# Conductor - Context-Driven Development Plugin for Claude Code
Conductor transforms Claude Code into a project management tool by implementing **Context-Driven Development**. It enforces a structured workflow: **Context → Spec & Plan → Implement**.
## Philosophy
By treating context as a managed artifact alongside code, teams establish a persistent, project-aware foundation for all AI interactions. The system maintains:
- **Product vision** as living documentation
- **Technical decisions** as structured artifacts
- **Work units (tracks)** with specifications and phased plans
- **TDD workflow** with verification checkpoints
## Features
- **Specification & Planning**: Generate detailed specs and actionable task plans before implementation
- **Context Management**: Maintain style guides, tech stack preferences, and product goals
- **Safe Iteration**: Review plans before code generation, keeping humans in control
- **Team Collaboration**: Project-level context documents become shared foundations
- **Project Intelligence**: Handles both greenfield (new) and brownfield (existing) projects
- **Semantic Reversion**: Git-aware revert by logical work units (tracks, phases, tasks)
- **State Persistence**: Resume setup across multiple sessions
## Commands
| Command | Description |
| ---------------------- | ---------------------------------------------------------------------------------- |
| `/conductor:setup` | Initialize project with product definition, tech stack, workflow, and style guides |
| `/conductor:new-track` | Create a feature or bug track with spec.md and plan.md |
| `/conductor:implement` | Execute tasks from the plan following workflow rules |
| `/conductor:status` | Display project progress overview |
| `/conductor:revert` | Git-aware undo by track, phase, or task |
## Generated Artifacts
```
conductor/
├── index.md # Navigation hub
├── product.md # Product vision & goals
├── product-guidelines.md # Standards & messaging
├── tech-stack.md # Technology preferences
├── workflow.md # Development practices (TDD, commits)
├── tracks.md # Master track registry
├── setup_state.json # Resumable setup state

└── tracks/
└── <track-id>/
├── spec.md # Requirements specification
├── plan.md # Phased task breakdown
├── metadata.json # Track metadata
└── index.md # Track navigation
```
## Workflow
### 1. Setup (`/conductor:setup`)
Interactive initialization that creates foundational project documentation:
- Detects greenfield vs brownfield projects
- Asks sequential questions about product, tech stack, workflow preferences
- Generates style guides for selected languages
- Creates tracks registry
### 2. Create Track (`/conductor:new-track`)
Start a new feature or bug fix:
- Interactive Q&A to gather requirements
- Generates detailed specification (spec.md)
- Creates phased implementation plan (plan.md)
- Registers track in tracks.md
### 3. Implement (`/conductor:implement`)
Execute the plan systematically:
- Follows TDD red-green-refactor cycle
- Updates task status markers
- Includes manual verification checkpoints
- Synchronizes documentation on completion
### 4. Monitor (`/conductor:status`)
View project progress:
- Current phase and task
- Completion percentage
- Identified blockers
### 5. Revert (`/conductor:revert`)
Undo work by logical unit:
- Select track, phase, or task to revert
- Git-aware: finds all associated commits
- Requires confirmation before execution
## Installation
```bash
claude --plugin-dir /path/to/conductor
```
Or copy to your project's `.claude-plugin/` directory.

---
You are an expert validator for Conductor project artifacts. Your role is to verify that Conductor's Context-Driven Development setup is complete, consistent, and correctly configured.
## When to Use This Agent
- After `/conductor:setup` completes to verify all artifacts were created correctly
- When a user reports issues with Conductor commands not working
- Before starting implementation to verify project context is complete
- When synchronizing documentation after track completion
## Validation Categories
### A. Setup Validation
Verify the foundational Conductor structure exists and is properly configured.
**Directory Check:**
- `conductor/` directory exists at project root
**Required Files:**
- `conductor/index.md` - Navigation hub
- `conductor/product.md` - Product vision and goals
- `conductor/product-guidelines.md` - Standards and messaging
- `conductor/tech-stack.md` - Technology preferences
- `conductor/workflow.md` - Development practices
- `conductor/tracks.md` - Master track registry
**File Integrity:**
- All required files exist
- Files are not empty (have meaningful content)
- Markdown structure is valid (proper headings, lists)
### B. Content Validation
Verify required sections exist within each artifact.
**product.md Required Sections:**
- Overview or Introduction
- Problem Statement
- Target Users
- Value Proposition
**tech-stack.md Required Elements:**
- Technology decisions documented
- At least one language/framework specified
- Rationale for choices (preferred)
**workflow.md Required Elements:**
- Task lifecycle defined
- TDD workflow (if applicable)
- Commit message conventions
- Review/verification checkpoints
**tracks.md Required Format:**
- Status legend present ([ ], [~], [x] markers)
- Separator line usage (----)
- Track listing section
### C. Track Validation
When tracks exist, verify each track is properly configured.
**Track Registry Consistency:**
- Each track listed in `tracks.md` has a corresponding directory in `conductor/tracks/`
- Track directories contain required files:
- `spec.md` - Requirements specification
- `plan.md` - Phased task breakdown
- `metadata.json` - Track metadata
**Status Marker Validation:**
- Status markers in `tracks.md` match actual track states
- `[ ]` = not started (no tasks marked in progress or complete)
- `[~]` = in progress (has tasks marked `[~]` in plan.md)
- `[x]` = complete (all tasks marked `[x]` in plan.md)
**Plan Task Markers:**
- Tasks use proper markers: `[ ]` (pending), `[~]` (in progress), `[x]` (complete)
- Phases are properly numbered and structured
- At most one task should be `[~]` at a time
### D. Consistency Validation
Verify cross-artifact consistency.
**Track ID Uniqueness:**
- All track IDs are unique
- Track IDs follow naming convention (e.g., `feature_name_YYYYMMDD`)
**Reference Resolution:**
- All track references in `tracks.md` resolve to existing directories
- Cross-references between documents are valid
**Metadata Consistency:**
- `metadata.json` in each track is valid JSON
- Metadata reflects actual track state (status, dates, etc.)
### E. State Validation
Verify state files are valid.
**setup_state.json (if exists):**
- Valid JSON structure
- State reflects actual file system state
- No orphaned or inconsistent state entries
## Validation Process
1. **Use Glob** to find all relevant files and directories
2. **Use Read** to check file contents and structure
3. **Use Grep** to search for specific patterns and markers
4. **Use Bash** only for directory existence checks (e.g., `ls -la`)
## Output Format
Always produce a structured validation report:
```
## Conductor Validation Report
### Summary
- Status: PASS | FAIL | WARNINGS
- Files checked: X
- Issues found: Y
### Setup Validation
- [x] conductor/ directory exists
- [x] index.md exists and valid
- [x] product.md exists and valid
- [x] product-guidelines.md exists and valid
- [x] tech-stack.md exists and valid
- [x] workflow.md exists and valid
- [x] tracks.md exists and valid
- [ ] tech-stack.md missing required sections
### Content Validation
- [x] product.md has required sections
- [ ] tech-stack.md missing "Backend" section
- [x] workflow.md has task lifecycle
### Track Validation (if tracks exist)
- Track: auth_20250115
- [x] Directory exists
- [x] spec.md present
- [x] plan.md present
- [x] metadata.json valid
- [ ] Status mismatch: tracks.md shows [~] but no tasks in progress
### Issues
1. [CRITICAL] tech-stack.md: Missing "Backend" section
2. [WARNING] Track "auth_20250115": Status is [~] but no tasks in progress in plan.md
3. [INFO] product.md: Consider adding more detail to Value Proposition
### Recommendations
1. Add Backend section to tech-stack.md with your server-side technology choices
2. Update track status in tracks.md to reflect actual progress
3. Expand Value Proposition in product.md (optional)
```
## Issue Severity Levels
**CRITICAL** - Validation failure that will break Conductor commands:
- Missing required files
- Invalid JSON in metadata files
- Missing required sections that commands depend on
**WARNING** - Inconsistencies that may cause confusion:
- Status markers don't match actual state
- Track references don't resolve
- Empty sections that should have content
**INFO** - Suggestions for improvement:
- Missing optional sections
- Best practice recommendations
- Documentation quality suggestions
## Key Rules
1. **Be thorough** - Check all files and cross-references
2. **Be concise** - Report findings clearly without excessive verbosity
3. **Be actionable** - Provide specific recommendations for each issue
4. **Read-only** - Never modify files; only validate and report
5. **Report all issues** - Don't stop at the first error; find everything
6. **Prioritize** - List CRITICAL issues first, then WARNING, then INFO
## Example Validation Commands
```bash
# Check if conductor directory exists
ls -la conductor/
# Find all track directories
ls -la conductor/tracks/
# Check for required files
ls conductor/index.md conductor/product.md conductor/tech-stack.md conductor/workflow.md conductor/tracks.md
```
## Pattern Matching
**Status markers in tracks.md:**
```
- [ ] Track Name # Not started
- [~] Track Name # In progress
- [x] Track Name # Complete
```
**Task markers in plan.md:**
```
- [ ] Task description # Pending
- [~] Task description # In progress
- [x] Task description # Complete
```
**Track ID pattern:**
```
<type>_<name>_<YYYYMMDD>
Example: feature_user_auth_20250115
```

description: Execute tasks from a track's implementation plan following workflow rules
model: opus
argument-hint: "[track-id]"
---
Execute tasks from a track's implementation plan, following the workflow rules defined in `conductor/workflow.md`.
## Pre-flight Checks
1. Verify Conductor is initialized:
- Check `conductor/product.md` exists
- Check `conductor/workflow.md` exists
- Check `conductor/tracks.md` exists
- If missing: Display error and suggest running `/conductor:setup` first
2. Load workflow configuration:
- Read `conductor/workflow.md`
- Parse TDD strictness level
- Parse commit strategy
- Parse verification checkpoint rules
## Track Selection
### If argument provided:
- Validate track exists: `conductor/tracks/{argument}/plan.md`
- If not found: Search for partial matches, suggest corrections
### If no argument:
1. Read `conductor/tracks.md`
2. Parse for incomplete tracks (status `[ ]` or `[~]`)
3. Display selection menu:
```
Select a track to implement:
In Progress:
1. [~] auth_20250115 - User Authentication (Phase 2, Task 3)
Pending:
2. [ ] nav-fix_20250114 - Navigation Bug Fix
3. [ ] dashboard_20250113 - Dashboard Feature
Enter number or track ID:
```
## Context Loading
Load all relevant context for implementation:
1. Track documents:
- `conductor/tracks/{trackId}/spec.md` - Requirements
- `conductor/tracks/{trackId}/plan.md` - Task list
- `conductor/tracks/{trackId}/metadata.json` - Progress state
2. Project context:
- `conductor/product.md` - Product understanding
- `conductor/tech-stack.md` - Technical constraints
- `conductor/workflow.md` - Process rules
3. Code style (if exists):
- `conductor/code_styleguides/{language}.md`
## Track Status Update
Update track to in-progress:
1. In `conductor/tracks.md`:
- Change `[ ]` to `[~]` for this track
2. In `conductor/tracks/{trackId}/metadata.json`:
- Set `status: "in_progress"`
- Update `updated` timestamp
## Task Execution Loop
For each incomplete task in plan.md (marked with `[ ]`):
### 1. Task Identification
Parse plan.md to find next incomplete task:
- Look for lines matching `- [ ] Task X.Y: {description}`
- Track current phase from structure
### 2. Task Start
Mark task as in-progress:
- Update plan.md: Change `[ ]` to `[~]` for current task
- Announce: "Starting Task X.Y: {description}"
### 3. TDD Workflow (if TDD enabled in workflow.md)
**Red Phase - Write Failing Test:**
```
Following TDD workflow for Task X.Y...
Step 1: Writing failing test
```
- Create test file if needed
- Write test(s) for the task functionality
- Run tests to confirm they fail
- If tests pass unexpectedly: HALT, investigate
**Green Phase - Implement:**
```
Step 2: Implementing minimal code to pass test
```
- Write minimum code to make test pass
- Run tests to confirm they pass
- If tests fail: Debug and fix
**Refactor Phase:**
```
Step 3: Refactoring while keeping tests green
```
- Clean up code
- Run tests to ensure still passing
### 4. Non-TDD Workflow (if TDD not strict)
- Implement the task directly
- Run any existing tests
- Manual verification as needed
### 5. Task Completion
**Commit changes** (following commit strategy from workflow.md):
```bash
git add -A
git commit -m "{commit_prefix}: {task description} ({trackId})"
```
**Update plan.md:**
- Change `[~]` to `[x]` for completed task
- Commit plan update:
```bash
git add conductor/tracks/{trackId}/plan.md
git commit -m "chore: mark task X.Y complete ({trackId})"
```
**Update metadata.json:**
- Increment `tasks.completed`
- Update `updated` timestamp
### 6. Phase Completion Check
After each task, check if phase is complete:
- Parse plan.md for phase structure
- If all tasks in current phase are `[x]`:
**Run phase verification:**
```
Phase {N} complete. Running verification...
```
- Execute verification tasks listed for the phase
- Run full test suite: `npm test` / `pytest` / etc.
**Report and wait for approval:**
```
Phase {N} Verification Results:
- All phase tasks: Complete
- Tests: {passing/failing}
- Verification: {pass/fail}
Approve to continue to Phase {N+1}?
1. Yes, continue
2. No, there are issues to fix
3. Pause implementation
```
**CRITICAL: Wait for explicit user approval before proceeding to next phase.**
## Error Handling During Implementation
### On Tool Failure
```
ERROR: {tool} failed with: {error message}
Options:
1. Retry the operation
2. Skip this task and continue
3. Pause implementation
4. Revert current task changes
```
- HALT and present options
- Do NOT automatically continue
### On Test Failure
```
TESTS FAILING after Task X.Y
Failed tests:
- {test name}: {failure reason}
Options:
1. Attempt to fix
2. Rollback task changes
3. Pause for manual intervention
```
### On Git Failure
```
GIT ERROR: {error message}
This may indicate:
- Uncommitted changes from outside Conductor
- Merge conflicts
- Permission issues
Options:
1. Show git status
2. Attempt to resolve
3. Pause for manual intervention
```
## Track Completion
When all phases and tasks are complete:
### 1. Final Verification
```
All tasks complete. Running final verification...
```
- Run full test suite
- Check all acceptance criteria from spec.md
- Generate verification report
### 2. Update Track Status
In `conductor/tracks.md`:
- Change `[~]` to `[x]` for this track
- Update the "Updated" column
In `conductor/tracks/{trackId}/metadata.json`:
- Set `status: "complete"`
- Set `phases.completed` to total
- Set `tasks.completed` to total
- Update `updated` timestamp
In `conductor/tracks/{trackId}/plan.md`:
- Update header status to `[x] Complete`
### 3. Documentation Sync Offer
```
Track complete! Would you like to sync documentation?
This will update:
- conductor/product.md (if new features added)
- conductor/tech-stack.md (if new dependencies added)
- README.md (if applicable)
1. Yes, sync documentation
2. No, skip
```
### 4. Cleanup Offer
```
Track {trackId} is complete.
Cleanup options:
1. Archive - Move to conductor/tracks/_archive/
2. Delete - Remove track directory
3. Keep - Leave as-is
```
### 5. Completion Summary
```
Track Complete: {track title}
Summary:
- Track ID: {trackId}
- Phases completed: {N}/{N}
- Tasks completed: {M}/{M}
- Commits created: {count}
- Tests: All passing
Next steps:
- Run /conductor:status to see project progress
- Run /conductor:new-track for next feature
```
## Progress Tracking
Maintain progress in `metadata.json` throughout:
```json
{
"id": "auth_20250115",
"title": "User Authentication",
"type": "feature",
"status": "in_progress",
"created": "2025-01-15T10:00:00Z",
"updated": "2025-01-15T14:30:00Z",
"current_phase": 2,
"current_task": "2.3",
"phases": {
"total": 3,
"completed": 1
},
"tasks": {
"total": 12,
"completed": 7
},
"commits": [
"abc1234: feat: add login form (auth_20250115)",
"def5678: feat: add password validation (auth_20250115)"
]
}
```
## Resumption
If implementation is paused and resumed:
1. Load `metadata.json` for current state
2. Find current task from `current_task` field
3. Check if task is `[~]` in plan.md
4. Ask user:
```
Resuming track: {title}
Last task in progress: Task {X.Y}: {description}
Options:
1. Continue from where we left off
2. Restart current task
3. Show progress summary first
```
## Critical Rules
1. **NEVER skip verification checkpoints** - Always wait for user approval between phases
2. **STOP on any failure** - Do not attempt to continue past errors
3. **Follow workflow.md strictly** - TDD, commit strategy, and verification rules are mandatory
4. **Keep plan.md updated** - Task status must reflect actual progress
5. **Commit frequently** - Each task completion should be committed
6. **Track all commits** - Record commit hashes in metadata.json for potential revert

name: new-track
description: Create a new feature or bug track with specification and phased implementation plan
model: opus
argument-hint: "[track description]"
---
Create a new track (feature, bug fix, chore, or refactor) with a detailed specification and phased implementation plan.
## Pre-flight Checks
1. Verify Conductor is initialized:
- Check `conductor/product.md` exists
- Check `conductor/tech-stack.md` exists
- Check `conductor/workflow.md` exists
- If missing: Display error and suggest running `/conductor:setup` first
2. Load context files:
- Read `conductor/product.md` for product context
- Read `conductor/tech-stack.md` for technical context
- Read `conductor/workflow.md` for TDD/commit preferences
## Track Classification
Determine track type based on description or ask user:
```
What type of track is this?
1. Feature - New functionality
2. Bug - Fix for existing issue
3. Chore - Maintenance, dependencies, config
4. Refactor - Code improvement without behavior change
```
## Interactive Specification Gathering
**CRITICAL RULES:**
- Ask ONE question per turn
- Wait for user response before proceeding
- Tailor questions based on track type
- Maximum 6 questions total

## Track ID Generation
Generate track ID in format: `{shortname}_{YYYYMMDD}`
- Extract shortname from feature/bug summary (2-3 words, lowercase, hyphenated)
- Use current date
- Example: `user-auth_20250115`, `nav-bug_20250115`
Validate uniqueness:
- Check `conductor/tracks.md` for existing IDs
- If collision, append counter: `user-auth_20250115_2`
## Specification Generation
Create `conductor/tracks/{trackId}/spec.md`:
```markdown
# Specification: {Track Title}
**Track ID:** {trackId}
**Type:** {Feature|Bug|Chore|Refactor}
**Created:** {YYYY-MM-DD}
**Status:** Draft
## Summary
{1-2 sentence summary}
## Context
{Product context from product.md relevant to this track}
## User Story (for features)
As a {user}, I want to {action} so that {benefit}.
## Problem Description (for bugs)
{Bug description, steps to reproduce}
## Acceptance Criteria
- [ ] {Criterion 1}
- [ ] {Criterion 2}
- [ ] {Criterion 3}
## Dependencies
{List dependencies or "None"}
## Out of Scope
{Explicit exclusions}
## Technical Notes
{Technical considerations or "None specified"}
---
_Generated by Conductor. Review and edit as needed._
```
## User Review of Spec
Display the generated spec and ask:
```
Here is the specification I've generated:
{spec content}
Is this specification correct?
1. Yes, proceed to plan generation
2. No, let me edit (opens for inline edits)
3. Start over with different inputs
```
## Plan Generation
After spec approval, generate `conductor/tracks/{trackId}/plan.md`:
### Plan Structure
```markdown
# Implementation Plan: {Track Title}
**Track ID:** {trackId}
**Spec:** [spec.md](./spec.md)
**Created:** {YYYY-MM-DD}
**Status:** [ ] Not Started
## Overview
{Brief summary of implementation approach}
## Phase 1: {Phase Name}
{Phase description}
### Tasks
- [ ] Task 1.1: {Description}
- [ ] Task 1.2: {Description}
- [ ] Task 1.3: {Description}
### Verification
- [ ] {Verification step for phase 1}
## Phase 2: {Phase Name}
{Phase description}
### Tasks
- [ ] Task 2.1: {Description}
- [ ] Task 2.2: {Description}
### Verification
- [ ] {Verification step for phase 2}
## Phase 3: {Phase Name} (if needed)
...
## Final Verification
- [ ] All acceptance criteria met
- [ ] Tests passing
- [ ] Documentation updated (if applicable)
- [ ] Ready for review
---
_Generated by Conductor. Tasks will be marked [~] in progress and [x] complete._
```
### Phase Guidelines
- Group related tasks into logical phases
- Each phase should be independently verifiable
- Include verification task after each phase
- TDD tracks: Include test writing tasks before implementation tasks
- Typical structure:
1. **Setup/Foundation** - Initial scaffolding, interfaces
2. **Core Implementation** - Main functionality
3. **Integration** - Connect with existing system
4. **Polish** - Error handling, edge cases, docs
## User Review of Plan
Display the generated plan and ask:
```
Here is the implementation plan:
{plan content}
Is this plan correct?
1. Yes, create the track
2. No, let me edit (opens for inline edits)
3. Add more phases/tasks
4. Start over
```
## Track Creation
After plan approval:
1. Create directory structure:
```
conductor/tracks/{trackId}/
├── spec.md
├── plan.md
├── metadata.json
└── index.md
```
2. Create `metadata.json`:
```json
{
"id": "{trackId}",
"title": "{Track Title}",
"type": "feature|bug|chore|refactor",
"status": "pending",
"created": "ISO_TIMESTAMP",
"updated": "ISO_TIMESTAMP",
"phases": {
"total": N,
"completed": 0
},
"tasks": {
"total": M,
"completed": 0
}
}
```
3. Create `index.md`:
```markdown
# Track: {Track Title}
**ID:** {trackId}
**Status:** Pending
## Documents
- [Specification](./spec.md)
- [Implementation Plan](./plan.md)
## Progress
- Phases: 0/{N} complete
- Tasks: 0/{M} complete
## Quick Links
- [Back to Tracks](../../tracks.md)
- [Product Context](../../product.md)
```
4. Register in `conductor/tracks.md`:
- Add row to tracks table
- Format: `| [ ] | {trackId} | {title} | {created} | {created} |`
5. Update `conductor/index.md`:
- Add track to "Active Tracks" section
## Completion Message
```
Track created successfully!
Track ID: {trackId}
Location: conductor/tracks/{trackId}/
Files created:
- spec.md - Requirements specification
- plan.md - Phased implementation plan
- metadata.json - Track metadata
- index.md - Track navigation
Next steps:
1. Review spec.md and plan.md, make any edits
2. Run /conductor:implement {trackId} to start implementation
3. Run /conductor:status to see project progress
```
## Error Handling
- If directory creation fails: Halt and report, do not register in tracks.md
- If any file write fails: Clean up partial track, report error
- If tracks.md update fails: Warn user to manually register track

Revert changes by logical work unit with full git awareness. Supports reverting entire tracks, specific phases, or individual tasks.
## Pre-flight Checks
1. Verify Conductor is initialized:
- Check `conductor/tracks.md` exists
- If missing: Display error and suggest running `/conductor:setup` first
2. Verify git repository:
- Run `git status` to confirm git repo
- Check for uncommitted changes
- If uncommitted changes exist:
```
WARNING: Uncommitted changes detected
Files with changes:
{list of files}
Options:
1. Stash changes and continue
2. Commit changes first
3. Cancel revert
```
3. Verify git is clean enough to revert:
- No merge in progress
- No rebase in progress
- If issues found: Halt and explain resolution steps
## Target Selection
### If argument provided:
Parse the argument format:
**Full track:** `{trackId}`
- Example: `auth_20250115`
- Reverts all commits for the entire track
**Specific phase:** `{trackId}:phase{N}`
- Example: `auth_20250115:phase2`
- Reverts commits for phase N and all subsequent phases
**Specific task:** `{trackId}:task{X.Y}`
- Example: `auth_20250115:task2.3`
- Reverts commits for task X.Y only
### If no argument:
Display guided selection menu:
```
What would you like to revert?
Currently In Progress:
1. [~] Task 2.3 in dashboard_20250112 (most recent)
Recently Completed:
2. [x] Task 2.2 in dashboard_20250112 (1 hour ago)

4. [x] Full track: auth_20250115 (yesterday)
Options:
5. Enter specific reference (track:phase or track:task)
6. Cancel
Select option:
```
## Commit Discovery
### For Task Revert
1. Search git log for task-specific commits:
```bash
git log --oneline --grep="{trackId}" --grep="Task {X.Y}" --all-match
```
2. Also find the plan.md update commit:
```bash
git log --oneline --grep="mark task {X.Y} complete" --grep="{trackId}" --all-match
```
3. Collect all matching commit SHAs
### For Phase Revert
1. Determine task range for the phase by reading plan.md
2. Search for all task commits in that phase:
```bash
git log --oneline --grep="{trackId}" | grep -E "Task {N}\.[0-9]"
```
3. Find phase verification commit if exists
4. Find all plan.md update commits for phase tasks
5. Collect all matching commit SHAs in chronological order
### For Full Track Revert
1. Find ALL commits mentioning the track:
```bash
git log --oneline --grep="{trackId}"
```
2. Find track creation commits:
```bash
git log --oneline -- "conductor/tracks/{trackId}/"
```
3. Collect all matching commit SHAs in chronological order
## Execution Plan Display
Before any revert operations, display full plan:
```
================================================================================
REVERT EXECUTION PLAN
================================================================================
Target: {description of what's being reverted}
Commits to revert (in reverse chronological order):
1. abc1234 - feat: add chart rendering (dashboard_20250112)
2. def5678 - chore: mark task 2.3 complete (dashboard_20250112)
3. ghi9012 - feat: add data hooks (dashboard_20250112)
4. jkl3456 - chore: mark task 2.2 complete (dashboard_20250112)
Files that will be affected:
- src/components/Dashboard.tsx (modified)
- src/hooks/useData.ts (will be deleted - was created in these commits)
- conductor/tracks/dashboard_20250112/plan.md (modified)
Plan updates:
- Task 2.2: [x] -> [ ]
- Task 2.3: [~] -> [ ]
================================================================================
!! WARNING !!
================================================================================
This operation will:
- Create {N} revert commits
- Modify {M} files
- Reset {P} tasks to pending status
This CANNOT be easily undone without manual intervention.
================================================================================
Type 'YES' to proceed, or anything else to cancel:
```
**CRITICAL: Require explicit 'YES' confirmation. Do not proceed on 'y', 'yes', or enter.**
## Revert Execution
Execute reverts in reverse chronological order (newest first):
```
Executing revert plan...
[1/4] Reverting abc1234...
git revert --no-edit abc1234
✓ Success
[2/4] Reverting def5678...
git revert --no-edit def5678
✓ Success
[3/4] Reverting ghi9012...
git revert --no-edit ghi9012
✓ Success
[4/4] Reverting jkl3456...
git revert --no-edit jkl3456
✓ Success
```
### On Merge Conflict
If any revert produces a merge conflict:
```
================================================================================
MERGE CONFLICT DETECTED
================================================================================
Conflict occurred while reverting: {sha} - {message}
Conflicted files:
- src/components/Dashboard.tsx
Options:
1. Show conflict details
2. Abort revert sequence (keeps completed reverts)
3. Open manual resolution guide
IMPORTANT: Reverts 1-{N} have been completed. You may need to manually
resolve this conflict before continuing or fully undo the revert sequence.
Select option:
```
**HALT immediately on any conflict. Do not attempt automatic resolution.**
## Plan.md Updates
After successful git reverts, update plan.md:
1. Read current plan.md
2. For each reverted task, change marker:
- `[x]` -> `[ ]`
- `[~]` -> `[ ]`
3. Write updated plan.md
4. Update metadata.json:
- Decrement `tasks.completed`
- Update `status` if needed
- Update `updated` timestamp
**Do NOT commit plan.md changes** - they are part of the revert operation
## Track Status Updates
### If reverting entire track:
- In tracks.md: Change `[x]` or `[~]` to `[ ]`
- Consider offering to delete the track directory entirely
### If reverting to incomplete state:
- In tracks.md: Ensure marked as `[~]` if partially complete, `[ ]` if fully reverted
## Verification
After revert completion:
```
================================================================================
REVERT COMPLETE
================================================================================
Summary:
- Reverted {N} commits
- Reset {P} tasks to pending
- {M} files affected
Git log now shows:
{recent commit history}
Plan.md status:
- Task 2.2: [ ] Pending
- Task 2.3: [ ] Pending
================================================================================
Verify the revert was successful:
1. Run tests: {test command}
2. Check application: {relevant check}
If issues are found, you may need to:
- Fix conflicts manually
- Re-implement the reverted tasks
- Use 'git revert HEAD~{N}..HEAD' to undo the reverts
================================================================================
```
## Safety Rules
1. **NEVER use `git reset --hard`** - Only use `git revert`
2. **NEVER use `git push --force`** - Only safe push operations
3. **NEVER auto-resolve conflicts** - Always halt for human intervention
4. **ALWAYS show full plan** - User must see exactly what will happen
5. **REQUIRE explicit 'YES'** - Not 'y', not enter, only 'YES'
6. **HALT on ANY error** - Do not attempt to continue past failures
7. **PRESERVE history** - Revert commits are preferred over history rewriting
## Edge Cases
### Track Never Committed
```
No commits found for track: {trackId}
The track exists but has no associated commits. This may mean:
- Implementation never started
- Commits used different format
Options:
1. Delete track directory only
2. Cancel
```
### Commits Already Reverted
```
Some commits appear to already be reverted:
- abc1234 was reverted by xyz9876
Options:
1. Skip already-reverted commits
2. Cancel and investigate
```
### Remote Already Pushed
```
WARNING: Some commits have been pushed to remote
Commits on remote:
- abc1234 (origin/main)
- def5678 (origin/main)
Reverting will create new revert commits that you'll need to push.
This is the safe approach (no force push required).
Continue with revert? (YES/no):
```
## Undo the Revert
If user needs to undo the revert itself:
```
To undo this revert operation:
git revert HEAD~{N}..HEAD
This will create new commits that restore the reverted changes.
Alternatively, if not yet pushed:
git reset --soft HEAD~{N}
git checkout -- .
(Use with caution - this discards the revert commits)
```

3. Squash commits per task
```
**Q3: Code Review Requirements**
```
What code review policy?
Suggested:
1. Required for all changes
2. Required for non-trivial changes
3. Optional / self-review OK
```
**Q4: Verification Checkpoints**
```
When should manual verification be required?
Suggested:
1. After each phase completion
2. After each task completion
3. Only at track completion
```
### Section 5: Code Style Guides (max 2 questions)
**Q1: Languages to Include**
```
Which language style guides should be generated?
[Based on detected languages, pre-select]
Options:
1. TypeScript/JavaScript
2. Python
3. Go
4. Rust
5. All detected languages
6. Skip style guides
```
**Q2: Existing Conventions**
```
Do you have existing linting/formatting configs to incorporate?
[For brownfield: "I found .eslintrc, .prettierrc. Should I incorporate these?"]
Suggested:
1. Yes, use existing configs
2. No, generate fresh guides
3. Skip this step
```
## Artifact Generation

<!-- Tracks registered by /conductor:new-track -->
```
### 7. conductor/code_styleguides/
Generate selected style guides from `$CLAUDE_PLUGIN_ROOT/templates/code_styleguides/`
## State Management
After each successful file creation:
1. Update `setup_state.json`:
- Add filename to `files_created` array
- Update `last_updated` timestamp
- If section complete, add to `completed_sections`
2. Verify file exists with `Read` tool
## Completion
When all files are created:
1. Set `setup_state.json` status to "complete"
2. Display summary:
```
Conductor setup complete!
Created artifacts:
- conductor/index.md
- conductor/product.md
- conductor/product-guidelines.md
- conductor/tech-stack.md
- conductor/workflow.md
- conductor/tracks.md
- conductor/code_styleguides/[languages]
Next steps:
1. Review generated files and customize as needed
2. Run /conductor:new-track to create your first track
```
## Resume Handling
If `--resume` argument or resuming from state:
1. Load `setup_state.json`
2. Skip completed sections
3. Resume from `current_section` and `current_question`
4. Verify previously created files still exist
5. If files missing, offer to regenerate
## Error Handling
- If file write fails: Halt and report error, do not update state
- If user cancels: Save current state for future resume
- If state file corrupted: Offer to start fresh or attempt recovery

# Context-Driven Development
Guide for implementing and maintaining context as a managed artifact alongside code, enabling consistent AI interactions and team alignment through structured project documentation.
## When to Use This Skill
- Setting up new projects with Conductor
- Understanding the relationship between context artifacts
- Maintaining consistency across AI-assisted development sessions
- Onboarding team members to an existing Conductor project
- Deciding when to update context documents
- Managing greenfield vs brownfield project contexts
## Core Philosophy
Context-Driven Development treats project context as a first-class artifact managed alongside code. Instead of relying on ad-hoc prompts or scattered documentation, establish a persistent, structured foundation that informs all AI interactions.
Key principles:
1. **Context precedes code**: Define what you're building and how before implementation
2. **Living documentation**: Context artifacts evolve with the project
3. **Single source of truth**: One canonical location for each type of information
4. **AI alignment**: Consistent context produces consistent AI behavior
## The Workflow
Follow the **Context → Spec & Plan → Implement** workflow:
1. **Context Phase**: Establish or verify project context artifacts exist and are current
2. **Specification Phase**: Define requirements and acceptance criteria for work units
3. **Planning Phase**: Break specifications into phased, actionable tasks
4. **Implementation Phase**: Execute tasks following established workflow patterns
## Artifact Relationships
### product.md - Defines WHAT and WHY
Purpose: Captures product vision, goals, target users, and business context.
Contents:
- Product name and one-line description
- Problem statement and solution approach
- Target user personas
- Core features and capabilities
- Success metrics and KPIs
- Product roadmap (high-level)
Update when:
- Product vision or goals change
- New major features are planned
- Target audience shifts
- Business priorities evolve
### product-guidelines.md - Defines HOW to Communicate
Purpose: Establishes brand voice, messaging standards, and communication patterns.
Contents:
- Brand voice and tone guidelines
- Terminology and glossary
- Error message conventions
- User-facing copy standards
- Documentation style
Update when:
- Brand guidelines change
- New terminology is introduced
- Communication patterns need refinement
### tech-stack.md - Defines WITH WHAT
Purpose: Documents technology choices, dependencies, and architectural decisions.
Contents:
- Primary languages and frameworks
- Key dependencies with versions
- Infrastructure and deployment targets
- Development tools and environment
- Testing frameworks
- Code quality tools
Update when:
- Adding new dependencies
- Upgrading major versions
- Changing infrastructure
- Adopting new tools or patterns
### workflow.md - Defines HOW to Work
Purpose: Establishes development practices, quality gates, and team workflows.
Contents:
- Development methodology (TDD, etc.)
- Git workflow and commit conventions
- Code review requirements
- Testing requirements and coverage targets
- Quality assurance gates
- Deployment procedures
Update when:
- Team practices evolve
- Quality standards change
- New workflow patterns are adopted
### tracks.md - Tracks WHAT'S HAPPENING
Purpose: Registry of all work units with status and metadata.
Contents:
- Active tracks with current status
- Completed tracks with completion dates
- Track metadata (type, priority, assignee)
- Links to individual track directories
Update when:
- New tracks are created
- Track status changes
- Tracks are completed or archived
## Context Maintenance Principles
### Keep Artifacts Synchronized
Ensure changes in one artifact reflect in related documents:
- New feature in product.md → Update tech-stack.md if new dependencies needed
- Completed track → Update product.md to reflect new capabilities
- Workflow change → Update all affected track plans
### Update tech-stack.md When Adding Dependencies
Before adding any new dependency:
1. Check if existing dependencies solve the need
2. Document the rationale for new dependencies
3. Add version constraints
4. Note any configuration requirements
### Update product.md When Features Complete
After completing a feature track:
1. Move feature from "planned" to "implemented" in product.md
2. Update any affected success metrics
3. Document any scope changes from original plan
### Verify Context Before Implementation
Before starting any track:
1. Read all context artifacts
2. Flag any outdated information
3. Propose updates before proceeding
4. Confirm context accuracy with stakeholders
## Greenfield vs Brownfield Handling
### Greenfield Projects (New)
For new projects:
1. Run `/conductor:setup` to create all artifacts interactively
2. Answer questions about product vision, tech preferences, and workflow
3. Generate initial style guides for chosen languages
4. Create empty tracks registry
Characteristics:
- Full control over context structure
- Define standards before code exists
- Establish patterns early
### Brownfield Projects (Existing)
For existing codebases:
1. Run `/conductor:setup` with existing codebase detection
2. System analyzes existing code, configs, and documentation
3. Pre-populate artifacts based on discovered patterns
4. Review and refine generated context
Characteristics:
- Extract implicit context from existing code
- Reconcile existing patterns with desired patterns
- Document technical debt and modernization plans
- Preserve working patterns while establishing standards
## Benefits
### Team Alignment
- New team members onboard faster with explicit context
- Consistent terminology and conventions across the team
- Shared understanding of product goals and technical decisions
### AI Consistency
- AI assistants produce aligned outputs across sessions
- Reduced need to re-explain context in each interaction
- Predictable behavior based on documented standards
### Institutional Memory
- Decisions and rationale are preserved
- Context survives team changes
- Historical context informs future decisions
### Quality Assurance
- Standards are explicit and verifiable
- Deviations from context are detectable
- Quality gates are documented and enforceable

## Context Lifecycle
1. **Creation**: Initial setup via `/conductor:setup`
2. **Validation**: Verify before each track
3. **Evolution**: Update as project grows
4. **Synchronization**: Keep artifacts aligned
5. **Archival**: Document historical decisions
## Context Validation Checklist
Before starting implementation on any track, validate context:
### Product Context
- [ ] product.md reflects current product vision
- [ ] Target users are accurately described
- [ ] Feature list is up to date
- [ ] Success metrics are defined
### Technical Context
- [ ] tech-stack.md lists all current dependencies
- [ ] Version numbers are accurate
- [ ] Infrastructure targets are correct
- [ ] Development tools are documented
### Workflow Context
- [ ] workflow.md describes current practices
- [ ] Quality gates are defined
- [ ] Coverage targets are specified
- [ ] Commit conventions are documented
### Track Context
- [ ] tracks.md shows all active work
- [ ] No stale or abandoned tracks
- [ ] Dependencies between tracks are noted
## Common Anti-Patterns
Avoid these context management mistakes:
### Stale Context
Problem: Context documents become outdated and misleading.
Solution: Update context as part of each track's completion process.
### Context Sprawl
Problem: Information scattered across multiple locations.
Solution: Use the defined artifact structure; resist creating new document types.
### Implicit Context
Problem: Relying on knowledge not captured in artifacts.
Solution: If you reference something repeatedly, add it to the appropriate artifact.
### Context Hoarding
Problem: One person maintains context without team input.
Solution: Review context artifacts in pull requests; make updates collaborative.
### Over-Specification
Problem: Context becomes so detailed it's impossible to maintain.
Solution: Keep artifacts focused on decisions that affect AI behavior and team alignment.
## Integration with Development Tools
### IDE Integration
Configure your IDE to display context files prominently:
- Pin conductor/product.md for quick reference
- Add tech-stack.md to project notes
- Create snippets for common patterns from style guides
### Git Hooks
Consider pre-commit hooks that:
- Warn when dependencies change without tech-stack.md update
- Remind to update product.md when feature branches merge
- Validate context artifact syntax
### CI/CD Integration
Include context validation in pipelines:
- Check tech-stack.md matches actual dependencies
- Verify links in context documents resolve
- Ensure tracks.md status matches git branch state
## Session Continuity
Conductor supports multi-session development through context persistence:
### Starting a New Session
1. Read index.md to orient yourself
2. Check tracks.md for active work
3. Review relevant track's plan.md for current task
4. Verify context artifacts are current
### Ending a Session
1. Update plan.md with current progress
2. Note any blockers or decisions made
3. Commit in-progress work with clear status
4. Update tracks.md if status changed
### Handling Interruptions
If interrupted mid-task:
1. Mark task as `[~]` with note about stopping point
2. Commit work-in-progress to feature branch
3. Document any uncommitted decisions in plan.md
## Best Practices
1. **Read context first**: Always read relevant artifacts before starting work
2. **Small updates**: Make incremental context changes, not massive rewrites
3. **Link decisions**: Reference context when making implementation choices
4. **Version context**: Commit context changes alongside code changes
5. **Review context**: Include context artifact reviews in code reviews
6. **Validate regularly**: Run context validation checklist before major work
7. **Communicate changes**: Notify team when context artifacts change significantly
8. **Preserve history**: Use git to track context evolution over time
9. **Question staleness**: If context feels wrong, investigate and update
10. **Keep it actionable**: Every context item should inform a decision or behavior

# Track Management
Guide for creating, managing, and completing Conductor tracks - the logical work units that organize features, bugs, and refactors through specification, planning, and implementation phases.
## When to Use This Skill
- Creating new feature, bug, or refactor tracks
- Writing or reviewing spec.md files
- Creating or updating plan.md files
- Managing track lifecycle from creation to completion
- Understanding track status markers and conventions
- Working with the tracks.md registry
- Interpreting or updating track metadata
## Track Concept
A track is a logical work unit that encapsulates a complete piece of work. Each track has:
- A unique identifier
- A specification defining requirements
- A phased plan breaking work into tasks
- Metadata tracking status and progress
Tracks provide semantic organization for work, enabling:
- Clear scope boundaries
- Progress tracking
- Git-aware operations (revert by track)
- Team coordination
## Track Types
### feature
New functionality or capabilities. Use for:
- New user-facing features
- New API endpoints
- New integrations
- Significant enhancements
### bug
Defect fixes. Use for:
- Incorrect behavior
- Error conditions
- Performance regressions
- Security vulnerabilities
### chore
Maintenance and housekeeping. Use for:
- Dependency updates
- Configuration changes
- Documentation updates
- Cleanup tasks
### refactor
Code improvement without behavior change. Use for:
- Code restructuring
- Pattern adoption
- Technical debt reduction
- Performance optimization (same behavior, better performance)
## Track ID Format
Track IDs follow the pattern: `{shortname}_{YYYYMMDD}`
- **shortname**: 2-4 word kebab-case description (e.g., `user-auth`, `api-rate-limit`)
- **YYYYMMDD**: Creation date in ISO format
Examples:
- `user-auth_20250115`
- `fix-login-error_20250115`
- `upgrade-deps_20250115`
- `refactor-api-client_20250115`

## Track Operations
### Creating a Track
1. Run `/conductor:new-track`
2. Answer interactive questions
3. Review generated spec.md
4. Review generated plan.md
5. Confirm track creation
### Starting Implementation
1. Read spec.md and plan.md
2. Verify context artifacts are current
3. Mark first task as `[~]`
4. Begin TDD workflow
### Completing a Phase
1. Ensure all phase tasks are `[x]`
2. Complete verification tasks
3. Wait for checkpoint approval
4. Record checkpoint SHA
5. Proceed to next phase
### Completing a Track
1. Verify all phases complete
2. Verify all acceptance criteria met
3. Update product.md if needed
4. Mark track completed in tracks.md
5. Update metadata.json
### Reverting a Track
1. Run `/conductor:revert`
2. Select track to revert
3. Choose granularity (track/phase/task)
4. Confirm revert operation
5. Update status markers
## Handling Track Dependencies
### Identifying Dependencies
During track creation, identify:
- **Hard dependencies**: Must complete before this track can start
- **Soft dependencies**: Can proceed in parallel but may affect integration
- **External dependencies**: Third-party services, APIs, or team decisions
### Documenting Dependencies
In spec.md, list dependencies with:
- Dependency type (hard/soft/external)
- Current status (available/pending/blocked)
- Resolution path (what needs to happen)
### Managing Blocked Tracks
When a track is blocked:
1. Mark blocked tasks with `[!]` and reason
2. Update tracks.md status
3. Document blocker in metadata.json
4. Consider creating dependency track if needed
## Track Sizing Guidelines
### Right-Sized Tracks
Aim for tracks that:
- Complete in 1-5 days of work
- Have 2-4 phases
- Contain 8-20 tasks total
- Deliver a coherent, testable unit
### Too Large
Signs a track is too large:
- More than 5 phases
- More than 25 tasks
- Multiple unrelated features
- Estimated duration > 1 week
Solution: Split into multiple tracks with clear boundaries.
### Too Small
Signs a track is too small:
- Single phase with 1-2 tasks
- No meaningful verification needed
- Could be a sub-task of another track
- Less than a few hours of work
Solution: Combine with related work or handle as part of existing track.
## Specification Quality Checklist
Before finalizing spec.md, verify:
### Requirements Quality
- [ ] Each requirement has clear acceptance criteria
- [ ] Requirements are testable
- [ ] Requirements are independent (can verify separately)
- [ ] No ambiguous language ("should be fast" → "response < 200ms")
### Scope Clarity
- [ ] In-scope items are specific
- [ ] Out-of-scope items prevent scope creep
- [ ] Boundaries are clear to implementer
### Dependencies Identified
- [ ] All internal dependencies listed
- [ ] External dependencies have owners/contacts
- [ ] Dependency status is current
### Risks Addressed
- [ ] Major risks identified
- [ ] Impact assessment realistic
- [ ] Mitigations are actionable
## Plan Quality Checklist
Before starting implementation, verify plan.md:
### Task Quality
- [ ] Tasks are atomic (one logical action)
- [ ] Tasks are independently verifiable
- [ ] Task descriptions are clear
- [ ] Sub-tasks provide helpful detail
### Phase Organization
- [ ] Phases group related tasks
- [ ] Each phase delivers something testable
- [ ] Verification tasks after each phase
- [ ] Phases build on each other logically
### Completeness
- [ ] All spec requirements have corresponding tasks
- [ ] Documentation tasks included
- [ ] Testing tasks included
- [ ] Integration tasks included
## Common Track Patterns
### Feature Track Pattern
```
Phase 1: Foundation
- Data models
- Database migrations
- Basic API structure
Phase 2: Core Logic
- Business logic implementation
- Input validation
- Error handling
Phase 3: Integration
- UI integration
- API documentation
- End-to-end tests
```
### Bug Fix Track Pattern
```
Phase 1: Reproduction
- Write failing test capturing bug
- Document reproduction steps
Phase 2: Fix
- Implement fix
- Verify test passes
- Check for regressions
Phase 3: Verification
- Manual verification
- Update documentation if needed
```
### Refactor Track Pattern
```
Phase 1: Preparation
- Add characterization tests
- Document current behavior
Phase 2: Refactoring
- Apply changes incrementally
- Maintain green tests throughout
Phase 3: Cleanup
- Remove dead code
- Update documentation
```
## Best Practices
1. **One track, one concern**: Keep tracks focused on a single logical change
2. **Small phases**: Break work into phases of 3-5 tasks maximum
3. **Verification after phases**: Always include verification tasks
4. **Update markers immediately**: Mark task status as you work
5. **Record SHAs**: Always note commit SHAs for completed tasks
6. **Review specs before planning**: Ensure spec is complete before creating plan
7. **Link dependencies**: Explicitly note track dependencies
8. **Archive, don't delete**: Preserve completed tracks for reference
9. **Size appropriately**: Keep tracks between 1-5 days of work
10. **Clear acceptance criteria**: Every requirement must be testable

# Workflow Patterns
Guide for implementing tasks using Conductor's TDD workflow, managing phase checkpoints, handling git commits, and executing the verification protocol that ensures quality throughout implementation.
## When to Use This Skill
- Implementing tasks from a track's plan.md
- Following TDD red-green-refactor cycle
- Completing phase checkpoints
- Managing git commits and notes
- Understanding quality assurance gates
- Handling verification protocols
- Recording progress in plan files
## TDD Task Lifecycle
Follow these 11 steps for each task:
### Step 1: Select Next Task
Read plan.md and identify the next pending `[ ]` task. Select tasks in order within the current phase. Do not skip ahead to later phases.
### Step 2: Mark as In Progress
Update plan.md to mark the task as `[~]`:
```markdown
- [~] **Task 2.1**: Implement user validation
```
Commit this status change separately from implementation.
### Step 3: RED - Write Failing Tests
Write tests that define the expected behavior before writing implementation:
- Create test file if needed
- Write test cases covering happy path
- Write test cases covering edge cases
- Write test cases covering error conditions
- Run tests - they should FAIL
Example:
```python
def test_validate_user_email_valid():
user = User(email="test@example.com")
assert user.validate_email() is True
def test_validate_user_email_invalid():
user = User(email="invalid")
assert user.validate_email() is False
```
### Step 4: GREEN - Implement Minimum Code
Write the minimum code necessary to make tests pass:
- Focus on making tests green, not perfection
- Avoid premature optimization
- Keep implementation simple
- Run tests - they should PASS
### Step 5: REFACTOR - Improve Clarity
With green tests, improve the code:
- Extract common patterns
- Improve naming
- Remove duplication
- Simplify logic
- Run tests after each change - they should remain GREEN
### Step 6: Verify Coverage
Check test coverage meets the 80% target:
```bash
pytest --cov=module --cov-report=term-missing
```
If coverage is below 80%:
- Identify uncovered lines
- Add tests for missing paths
- Re-run coverage check
### Step 7: Document Deviations
If implementation deviated from plan or introduced new dependencies:
- Update tech-stack.md with new dependencies
- Note deviations in plan.md task comments
- Update spec.md if requirements changed
### Step 8: Commit Implementation
Create a focused commit for the task:
```bash
git add -A
git commit -m "feat(user): implement email validation
- Add validate_email method to User class
- Handle empty and malformed emails
- Add comprehensive test coverage
Task: 2.1
Track: user-auth_20250115"
```
Commit message format:
- Type: feat, fix, refactor, test, docs, chore
- Scope: affected module or component
- Summary: imperative, present tense
- Body: bullet points of changes
- Footer: task and track references
### Step 9: Attach Git Notes
Add rich task summary as git note:
```bash
git notes add -m "Task 2.1: Implement user validation
Summary:
- Added email validation using regex pattern
- Handles edge cases: empty, no @, no domain
- Coverage: 94% on validation module
Files changed:
- src/models/user.py (modified)
- tests/test_user.py (modified)
Decisions:
- Used simple regex over email-validator library
- Reason: No external dependency for basic validation"
```
### Step 10: Update Plan with SHA
Update plan.md to mark task complete with commit SHA:
```markdown
- [x] **Task 2.1**: Implement user validation `abc1234`
```
### Step 11: Commit Plan Update
Commit the plan status update:
```bash
git add conductor/tracks/*/plan.md
git commit -m "docs: update plan - task 2.1 complete
Track: user-auth_20250115"
```
## Phase Completion Protocol
When all tasks in a phase are complete, execute the verification protocol:
### Identify Changed Files
List all files modified since the last checkpoint:
```bash
git diff --name-only <last-checkpoint-sha>..HEAD
```
### Ensure Test Coverage
For each modified file:
1. Identify corresponding test file
2. Verify tests exist for new/changed code
3. Run coverage for modified modules
4. Add tests if coverage < 80%
### Run Full Test Suite
Execute complete test suite:
```bash
pytest -v --tb=short
```
All tests must pass before proceeding.
### Generate Manual Verification Steps
Create checklist of manual verifications:
```markdown
## Phase 1 Verification Checklist
- [ ] User can register with valid email
- [ ] Invalid email shows appropriate error
- [ ] Database stores user correctly
- [ ] API returns expected response codes
```
### WAIT for User Approval
Present verification checklist to user:
```
Phase 1 complete. Please verify:
1. [ ] Test suite passes (automated)
2. [ ] Coverage meets target (automated)
3. [ ] Manual verification items (requires human)
Respond with 'approved' to continue, or note issues.
```
Do NOT proceed without explicit approval.
### Create Checkpoint Commit
After approval, create checkpoint commit:
```bash
git add -A
git commit -m "checkpoint: phase 1 complete - user-auth_20250115
Verified:
- All tests passing
- Coverage: 87%
- Manual verification approved
Phase 1 tasks:
- [x] Task 1.1: Setup database schema
- [x] Task 1.2: Implement user model
- [x] Task 1.3: Add validation logic"
```
### Record Checkpoint SHA
Update plan.md checkpoints table:
```markdown
## Checkpoints
| Phase | Checkpoint SHA | Date | Status |
| ------- | -------------- | ---------- | -------- |
| Phase 1 | def5678 | 2025-01-15 | verified |
| Phase 2 | | | pending |
```
## Quality Assurance Gates
Before marking any task complete, verify these gates:
### Passing Tests
- All existing tests pass
- New tests pass
- No test regressions
### Coverage >= 80%
- New code has 80%+ coverage
- Overall project coverage maintained
- Critical paths fully covered
### Style Compliance
- Code follows style guides
- Linting passes
- Formatting correct
### Documentation
- Public APIs documented
- Complex logic explained
- README updated if needed
### Type Safety
- Type hints present (if applicable)
- Type checker passes
- No type: ignore without reason
### No Linting Errors
- Zero linter errors
- Warnings addressed or justified
- Static analysis clean
### Mobile Compatibility
If applicable:
- Responsive design verified
- Touch interactions work
- Performance acceptable
### Security Audit
- No secrets in code
- Input validation present
- Authentication/authorization correct
- Dependencies vulnerability-free
## Git Integration
### Commit Message Format
```
<type>(<scope>): <subject>
<body>
<footer>
```
Types:
- `feat`: New feature
- `fix`: Bug fix
- `refactor`: Code change without feature/fix
- `test`: Adding tests
- `docs`: Documentation
- `chore`: Maintenance
### Git Notes for Rich Summaries
Attach detailed notes to commits:
```bash
git notes add -m "<detailed summary>"
```
View notes:
```bash
git log --show-notes
```
Benefits:
- Preserves context without cluttering commit message
- Enables semantic queries across commits
- Supports track-based operations
### SHA Recording in plan.md
Always record the commit SHA when completing tasks:
```markdown
- [x] **Task 1.1**: Setup schema `abc1234`
- [x] **Task 1.2**: Add model `def5678`
```
This enables:
- Traceability from plan to code
- Semantic revert operations
- Progress auditing
## Verification Checkpoints
### Why Checkpoints Matter
Checkpoints create restore points for semantic reversion:
- Revert to end of any phase
- Maintain logical code state
- Enable safe experimentation
### When to Create Checkpoints
Create checkpoint after:
- All phase tasks complete
- All phase verifications pass
- User approval received
### Checkpoint Commit Content
Include in checkpoint commit:
- All uncommitted changes
- Updated plan.md
- Updated metadata.json
- Any documentation updates
### How to Use Checkpoints
For reverting:
```bash
# Revert to end of Phase 1
git revert --no-commit <phase-2-commits>...
git commit -m "revert: rollback to phase 1 checkpoint"
```
For review:
```bash
# See what changed in Phase 2
git diff <phase-1-sha>..<phase-2-sha>
```
## Handling Deviations
During implementation, deviations from the plan may occur. Handle them systematically:
### Types of Deviations
**Scope Addition**
Discovered requirement not in original spec.
- Document in spec.md as new requirement
- Add tasks to plan.md
- Note addition in task comments
**Scope Reduction**
Feature deemed unnecessary during implementation.
- Mark tasks as `[-]` (skipped) with reason
- Update spec.md scope section
- Document decision rationale
**Technical Deviation**
Different implementation approach than planned.
- Note deviation in task completion comment
- Update tech-stack.md if dependencies changed
- Document why original approach was unsuitable
**Requirement Change**
Understanding of requirement changes during work.
- Update spec.md with corrected requirement
- Adjust plan.md tasks if needed
- Re-verify acceptance criteria
### Deviation Documentation Format
When completing a task with deviation:
```markdown
- [x] **Task 2.1**: Implement validation `abc1234`
- DEVIATION: Used library instead of custom code
- Reason: Better edge case handling
- Impact: Added email-validator to dependencies
```
## Error Recovery
### Failed Tests After GREEN
If tests fail after reaching GREEN:
1. Do NOT proceed to REFACTOR
2. Identify which test started failing
3. Check if refactoring broke something
4. Revert to last known GREEN state
5. Re-approach the implementation
### Checkpoint Rejection
If user rejects a checkpoint:
1. Note rejection reason in plan.md
2. Create tasks to address issues
3. Complete remediation tasks
4. Request checkpoint approval again
### Blocked by Dependency
If task cannot proceed:
1. Mark task as `[!]` with blocker description
2. Check if other tasks can proceed
3. Document expected resolution timeline
4. Consider creating dependency resolution track
## TDD Variations by Task Type
### Data Model Tasks
```
RED: Write test for model creation and validation
GREEN: Implement model class with fields
REFACTOR: Add computed properties, improve types
```
### API Endpoint Tasks
```
RED: Write test for request/response contract
GREEN: Implement endpoint handler
REFACTOR: Extract validation, improve error handling
```
### Integration Tasks
```
RED: Write test for component interaction
GREEN: Wire components together
REFACTOR: Improve error propagation, add logging
```
### Refactoring Tasks
```
RED: Add characterization tests for current behavior
GREEN: Apply refactoring (tests should stay green)
REFACTOR: Clean up any introduced complexity
```
## Working with Existing Tests
When modifying code with existing tests:
### Extend, Don't Replace
- Keep existing tests passing
- Add new tests for new behavior
- Update tests only when requirements change
### Test Migration
When refactoring changes test structure:
1. Run existing tests (should pass)
2. Add new tests for refactored code
3. Migrate test cases to new structure
4. Remove old tests only after new tests pass
### Regression Prevention
After any change:
1. Run full test suite
2. Check for unexpected failures
3. Investigate any new failures
4. Fix regressions before proceeding
## Checkpoint Verification Details
### Automated Verification
Run before requesting approval:
```bash
# Test suite
pytest -v --tb=short
# Coverage
pytest --cov=src --cov-report=term-missing
# Linting
ruff check src/ tests/
# Type checking (if applicable)
mypy src/
```
### Manual Verification Guidance
For manual items, provide specific instructions:
```markdown
## Manual Verification Steps
### User Registration
1. Navigate to /register
2. Enter valid email: test@example.com
3. Enter password meeting requirements
4. Click Submit
5. Verify success message appears
6. Verify user appears in database
### Error Handling
1. Enter invalid email: "notanemail"
2. Verify error message shows
3. Verify form retains other entered data
```
## Performance Considerations
### Test Suite Performance
Keep test suite fast:
- Use fixtures to avoid redundant setup
- Mock slow external calls
- Run subset during development, full suite at checkpoints
### Commit Performance
Keep commits atomic:
- One logical change per commit
- Complete thought, not work-in-progress
- Tests should pass after every commit
## Best Practices
1. **Never skip RED**: Always write failing tests first
2. **Small commits**: One logical change per commit
3. **Immediate updates**: Update plan.md right after task completion
4. **Wait for approval**: Never skip checkpoint verification
5. **Rich git notes**: Include context that helps future understanding
6. **Coverage discipline**: Don't accept coverage below target
7. **Quality gates**: Check all gates before marking complete
8. **Sequential phases**: Complete phases in order
9. **Document deviations**: Note any changes from original plan
10. **Clean state**: Each commit should leave code in working state
11. **Fast feedback**: Run relevant tests frequently during development
12. **Clear blockers**: Address blockers promptly, don't work around them

# C# Style Guide
C# conventions and best practices for .NET development.
## Naming Conventions
### General Rules
```csharp
// PascalCase for public members, types, namespaces
public class UserService { }
public void ProcessOrder() { }
public string FirstName { get; set; }
// camelCase for private fields, parameters, locals
private readonly ILogger _logger;
private int _itemCount;
public void DoWork(string inputValue) { }
// Prefix interfaces with I
public interface IUserRepository { }
public interface INotificationService { }
// Suffix async methods with Async
public async Task<User> GetUserAsync(int id) { }
public async Task ProcessOrderAsync(Order order) { }
// Constants: PascalCase (not SCREAMING_CASE)
public const int MaxRetryCount = 3;
public const string DefaultCurrency = "USD";
```
### Field and Property Naming
```csharp
public class Order
{
// Private fields: underscore prefix + camelCase
private readonly IOrderRepository _repository;
private int _itemCount;
// Public properties: PascalCase
public int Id { get; set; }
public string CustomerName { get; set; }
public DateTime CreatedAt { get; init; }
// Boolean properties: Is/Has/Can prefix
public bool IsActive { get; set; }
public bool HasDiscount { get; set; }
public bool CanEdit { get; }
}
```
## Async/Await Patterns
### Basic Async Usage
```csharp
// Always use async/await for I/O operations
public async Task<User> GetUserAsync(int id)
{
var user = await _repository.FindAsync(id);
if (user == null)
{
throw new NotFoundException($"User {id} not found");
}
return user;
}
// Don't block on async code
// Bad
var user = GetUserAsync(id).Result;
// Good
var user = await GetUserAsync(id);
```
### Async Best Practices
```csharp
// Use ConfigureAwait(false) in library code
public async Task<Data> FetchDataAsync()
{
var response = await _httpClient.GetAsync(url)
.ConfigureAwait(false);
return await response.Content.ReadAsAsync<Data>()
.ConfigureAwait(false);
}
// Avoid async void except for event handlers
// Bad
public async void ProcessOrder() { }
// Good
public async Task ProcessOrderAsync() { }
// Event handler exception
private async void Button_Click(object sender, EventArgs e)
{
try
{
await ProcessOrderAsync();
}
catch (Exception ex)
{
HandleError(ex);
}
}
```
### Parallel Async Operations
```csharp
// Execute independent operations in parallel
public async Task<DashboardData> LoadDashboardAsync()
{
var usersTask = _userService.GetActiveUsersAsync();
var ordersTask = _orderService.GetRecentOrdersAsync();
var statsTask = _statsService.GetDailyStatsAsync();
await Task.WhenAll(usersTask, ordersTask, statsTask);
return new DashboardData
{
Users = await usersTask,
Orders = await ordersTask,
Stats = await statsTask
};
}
// Use SemaphoreSlim for throttling
public async Task ProcessItemsAsync(IEnumerable<Item> items)
{
using var semaphore = new SemaphoreSlim(10); // Max 10 concurrent
var tasks = items.Select(async item =>
{
await semaphore.WaitAsync();
try
{
await ProcessItemAsync(item);
}
finally
{
semaphore.Release();
}
});
await Task.WhenAll(tasks);
}
```
## LINQ
### Query Syntax vs Method Syntax
```csharp
// Method syntax (preferred for simple queries)
var activeUsers = users
.Where(u => u.IsActive)
.OrderBy(u => u.Name)
.ToList();
// Query syntax (for complex queries with joins)
var orderSummary =
from order in orders
join customer in customers on order.CustomerId equals customer.Id
where order.Total > 100
group order by customer.Name into g
select new { Customer = g.Key, Total = g.Sum(o => o.Total) };
```
### LINQ Best Practices
```csharp
// Use appropriate methods
var hasItems = items.Any(); // Not: items.Count() > 0
var firstOrDefault = items.FirstOrDefault(); // Not: items.First()
var count = items.Count; // Property, not Count()
// Avoid multiple enumerations
// Bad
if (items.Any())
{
foreach (var item in items) { }
}
// Good
var itemList = items.ToList();
if (itemList.Count > 0)
{
foreach (var item in itemList) { }
}
// Project early to reduce memory
var names = users
.Where(u => u.IsActive)
.Select(u => u.Name) // Select only what you need
.ToList();
```
### Common LINQ Operations
```csharp
// Filtering
var adults = people.Where(p => p.Age >= 18);
// Transformation
var names = people.Select(p => $"{p.FirstName} {p.LastName}");
// Aggregation
var total = orders.Sum(o => o.Amount);
var average = scores.Average();
var max = values.Max();
// Grouping
var byDepartment = employees
.GroupBy(e => e.Department)
.Select(g => new { Department = g.Key, Count = g.Count() });
// Joining
var result = orders
.Join(customers,
o => o.CustomerId,
c => c.Id,
(o, c) => new { Order = o, Customer = c });
// Flattening
var allOrders = customers.SelectMany(c => c.Orders);
```
## Dependency Injection
### Service Registration
```csharp
// In Program.cs or Startup.cs
public void ConfigureServices(IServiceCollection services)
{
// Transient: new instance each time
services.AddTransient<IEmailService, EmailService>();
// Scoped: one instance per request
services.AddScoped<IUserRepository, UserRepository>();
// Singleton: one instance for app lifetime
services.AddSingleton<ICacheService, MemoryCacheService>();
// Factory registration
services.AddScoped<IDbConnection>(sp =>
{
var config = sp.GetRequiredService<IConfiguration>();
return new SqlConnection(config.GetConnectionString("Default"));
});
}
```
### Constructor Injection
```csharp
public class OrderService : IOrderService
{
private readonly IOrderRepository _repository;
private readonly ILogger<OrderService> _logger;
private readonly IEmailService _emailService;
public OrderService(
IOrderRepository repository,
ILogger<OrderService> logger,
IEmailService emailService)
{
_repository = repository ?? throw new ArgumentNullException(nameof(repository));
_logger = logger ?? throw new ArgumentNullException(nameof(logger));
_emailService = emailService ?? throw new ArgumentNullException(nameof(emailService));
}
public async Task<Order> CreateOrderAsync(OrderRequest request)
{
_logger.LogInformation("Creating order for customer {CustomerId}", request.CustomerId);
var order = new Order(request);
await _repository.SaveAsync(order);
await _emailService.SendOrderConfirmationAsync(order);
return order;
}
}
```
### Options Pattern
```csharp
// Configuration class
public class EmailSettings
{
public string SmtpServer { get; set; }
public int Port { get; set; }
public string FromAddress { get; set; }
}
// Registration
services.Configure<EmailSettings>(
configuration.GetSection("Email"));
// Usage
public class EmailService
{
private readonly EmailSettings _settings;
public EmailService(IOptions<EmailSettings> options)
{
_settings = options.Value;
}
}
```
## Testing
### xUnit Basics
```csharp
public class CalculatorTests
{
[Fact]
public void Add_TwoPositiveNumbers_ReturnsSum()
{
// Arrange
var calculator = new Calculator();
// Act
var result = calculator.Add(2, 3);
// Assert
Assert.Equal(5, result);
}
[Theory]
[InlineData(1, 1, 2)]
[InlineData(0, 0, 0)]
[InlineData(-1, 1, 0)]
public void Add_VariousNumbers_ReturnsCorrectSum(int a, int b, int expected)
{
var calculator = new Calculator();
Assert.Equal(expected, calculator.Add(a, b));
}
}
```
### Mocking with Moq
```csharp
public class OrderServiceTests
{
private readonly Mock<IOrderRepository> _mockRepository;
private readonly Mock<ILogger<OrderService>> _mockLogger;
private readonly OrderService _service;
public OrderServiceTests()
{
_mockRepository = new Mock<IOrderRepository>();
_mockLogger = new Mock<ILogger<OrderService>>();
_service = new OrderService(_mockRepository.Object, _mockLogger.Object);
}
[Fact]
public async Task GetOrderAsync_ExistingOrder_ReturnsOrder()
{
// Arrange
var expectedOrder = new Order { Id = 1, Total = 100m };
_mockRepository
.Setup(r => r.FindAsync(1))
.ReturnsAsync(expectedOrder);
// Act
var result = await _service.GetOrderAsync(1);
// Assert
Assert.Equal(expectedOrder.Id, result.Id);
_mockRepository.Verify(r => r.FindAsync(1), Times.Once);
}
[Fact]
public async Task GetOrderAsync_NonExistingOrder_ThrowsNotFoundException()
{
// Arrange
_mockRepository
.Setup(r => r.FindAsync(999))
.ReturnsAsync((Order)null);
// Act & Assert
await Assert.ThrowsAsync<NotFoundException>(
() => _service.GetOrderAsync(999));
}
}
```
### Integration Testing
```csharp
public class ApiIntegrationTests : IClassFixture<WebApplicationFactory<Program>>
{
private readonly HttpClient _client;
public ApiIntegrationTests(WebApplicationFactory<Program> factory)
{
_client = factory.CreateClient();
}
[Fact]
public async Task GetUsers_ReturnsSuccessAndCorrectContentType()
{
// Act
var response = await _client.GetAsync("/api/users");
// Assert
response.EnsureSuccessStatusCode();
Assert.Equal("application/json; charset=utf-8",
response.Content.Headers.ContentType.ToString());
}
}
```
## Common Patterns
### Null Handling
```csharp
// Null-conditional operators
var length = customer?.Address?.Street?.Length;
var name = user?.Name ?? "Unknown";
// Null-coalescing assignment
list ??= new List<Item>();
// Pattern matching for null checks
if (user is not null)
{
ProcessUser(user);
}
// Guard clauses
public void ProcessOrder(Order order)
{
ArgumentNullException.ThrowIfNull(order);
if (order.Items.Count == 0)
{
throw new ArgumentException("Order must have items", nameof(order));
}
// Process...
}
```
### Records and Init-Only Properties
```csharp
// Record for immutable data
public record User(int Id, string Name, string Email);
// Record with additional members
public record Order
{
public int Id { get; init; }
public string CustomerName { get; init; }
public decimal Total { get; init; }
public bool IsHighValue => Total > 1000;
}
// Record mutation via with expression
var updatedUser = user with { Name = "New Name" };
```
### Pattern Matching
```csharp
// Type patterns
public decimal CalculateDiscount(object customer) => customer switch
{
PremiumCustomer p => p.PurchaseTotal * 0.2m,
RegularCustomer r when r.YearsActive > 5 => r.PurchaseTotal * 0.1m,
RegularCustomer r => r.PurchaseTotal * 0.05m,
null => 0m,
_ => throw new ArgumentException("Unknown customer type")
};
// Property patterns
public string GetShippingOption(Order order) => order switch
{
{ Total: > 100, IsPriority: true } => "Express",
{ Total: > 100 } => "Standard",
{ IsPriority: true } => "Priority",
_ => "Economy"
};
// List patterns (C# 11)
public bool IsValidSequence(int[] numbers) => numbers switch
{
[1, 2, 3] => true,
[1, .., 3] => true,
[_, _, ..] => numbers.Length >= 2,
_ => false
};
```
### Disposable Pattern
```csharp
public class ResourceManager : IDisposable
{
private bool _disposed;
private readonly FileStream _stream;
public ResourceManager(string path)
{
_stream = File.OpenRead(path);
}
public void DoWork()
{
ObjectDisposedException.ThrowIf(_disposed, this);
// Work with _stream
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool disposing)
{
if (_disposed) return;
if (disposing)
{
_stream?.Dispose();
}
_disposed = true;
}
}
// Using statement
using var manager = new ResourceManager("file.txt");
manager.DoWork();
```
## Code Organization
### File Structure
```csharp
// One type per file (generally)
// Filename matches type name: UserService.cs
// Order of members
public class UserService
{
// 1. Constants
private const int MaxRetries = 3;
// 2. Static fields
private static readonly object _lock = new();
// 3. Instance fields
private readonly IUserRepository _repository;
// 4. Constructors
public UserService(IUserRepository repository)
{
_repository = repository;
}
// 5. Properties
public int TotalUsers { get; private set; }
// 6. Public methods
public async Task<User> GetUserAsync(int id) { }
// 7. Private methods
private void ValidateUser(User user) { }
}
```

# Dart/Flutter Style Guide
Dart language conventions and Flutter-specific patterns.
## Null Safety
### Enable Sound Null Safety
```dart
// pubspec.yaml
environment:
sdk: '>=3.0.0 <4.0.0'
// All types are non-nullable by default
String name = 'John'; // Cannot be null
String? nickname; // Can be null
// Late initialization
late final Database database;
```
### Null-Aware Operators
```dart
// Null-aware access
final length = user?.name?.length;
// Null-aware assignment
nickname ??= 'Anonymous';
// Null assertion (use sparingly)
final definitelyNotNull = maybeNull!;
// Null-aware cascade
user
?..name = 'John'
..email = 'john@example.com';
// Null coalescing
final displayName = user.nickname ?? user.name ?? 'Unknown';
```
### Null Handling Patterns
```dart
// Guard clause with null check
void processUser(User? user) {
if (user == null) {
throw ArgumentError('User cannot be null');
}
// user is promoted to non-nullable here
print(user.name);
}
// Pattern matching (Dart 3)
void handleResult(Result? result) {
switch (result) {
case Success(data: final data):
handleSuccess(data);
case Error(message: final message):
handleError(message);
case null:
handleNull();
}
}
```
## Async/Await
### Future Basics
```dart
// Async function
Future<User> fetchUser(int id) async {
final response = await http.get(Uri.parse('/users/$id'));
if (response.statusCode != 200) {
throw HttpException('Failed to fetch user');
}
return User.fromJson(jsonDecode(response.body));
}
// Error handling
Future<User?> safeFetchUser(int id) async {
try {
return await fetchUser(id);
} on HttpException catch (e) {
logger.error('HTTP error: ${e.message}');
return null;
} catch (e) {
logger.error('Unexpected error: $e');
return null;
}
}
```
### Parallel Execution
```dart
// Wait for all futures
Future<Dashboard> loadDashboard() async {
final results = await Future.wait([
fetchUsers(),
fetchOrders(),
fetchStats(),
]);
return Dashboard(
users: results[0] as List<User>,
orders: results[1] as List<Order>,
stats: results[2] as Stats,
);
}
// With typed results
Future<(List<User>, List<Order>)> loadData() async {
final (users, orders) = await (
fetchUsers(),
fetchOrders(),
).wait;
return (users, orders);
}
```
### Streams
```dart
// Stream creation
Stream<int> countStream(int max) async* {
for (var i = 0; i < max; i++) {
await Future.delayed(const Duration(seconds: 1));
yield i;
}
}
// Stream transformation
Stream<String> userNames(Stream<User> users) {
return users.map((user) => user.name);
}
// Stream consumption
void listenToUsers() {
userStream.listen(
(user) => print('New user: ${user.name}'),
onError: (error) => print('Error: $error'),
onDone: () => print('Stream closed'),
);
}
```
## Widgets
### Stateless Widgets
```dart
class UserCard extends StatelessWidget {
const UserCard({
super.key,
required this.user,
this.onTap,
});
final User user;
final VoidCallback? onTap;
@override
Widget build(BuildContext context) {
return Card(
child: ListTile(
leading: CircleAvatar(
backgroundImage: NetworkImage(user.avatarUrl),
),
title: Text(user.name),
subtitle: Text(user.email),
onTap: onTap,
),
);
}
}
```
### Stateful Widgets
```dart
class Counter extends StatefulWidget {
const Counter({super.key, this.initialValue = 0});
final int initialValue;
@override
State<Counter> createState() => _CounterState();
}
class _CounterState extends State<Counter> {
late int _count;
@override
void initState() {
super.initState();
_count = widget.initialValue;
}
void _increment() {
setState(() {
_count++;
});
}
@override
Widget build(BuildContext context) {
return Column(
children: [
Text('Count: $_count'),
ElevatedButton(
onPressed: _increment,
child: const Text('Increment'),
),
],
);
}
}
```
### Widget Best Practices
```dart
// Use const constructors
class MyWidget extends StatelessWidget {
const MyWidget({super.key}); // const constructor
@override
Widget build(BuildContext context) {
return const Column(
children: [
Text('Hello'), // const widget
SizedBox(height: 8), // const widget
],
);
}
}
// Extract widgets for reusability
class PrimaryButton extends StatelessWidget {
const PrimaryButton({
super.key,
required this.label,
required this.onPressed,
this.isLoading = false,
});
final String label;
final VoidCallback? onPressed;
final bool isLoading;
@override
Widget build(BuildContext context) {
return ElevatedButton(
onPressed: isLoading ? null : onPressed,
child: isLoading
? const SizedBox(
width: 20,
height: 20,
child: CircularProgressIndicator(strokeWidth: 2),
)
: Text(label),
);
}
}
```
## State Management
### Provider Pattern
```dart
// Model with ChangeNotifier
class CartModel extends ChangeNotifier {
final List<Item> _items = [];
List<Item> get items => List.unmodifiable(_items);
double get totalPrice => _items.fold(0, (sum, item) => sum + item.price);
void addItem(Item item) {
_items.add(item);
notifyListeners();
}
void removeItem(Item item) {
_items.remove(item);
notifyListeners();
}
}
// Provider setup
void main() {
runApp(
ChangeNotifierProvider(
create: (_) => CartModel(),
child: const MyApp(),
),
);
}
// Consuming provider
class CartPage extends StatelessWidget {
const CartPage({super.key});
@override
Widget build(BuildContext context) {
return Consumer<CartModel>(
builder: (context, cart, child) {
return ListView.builder(
itemCount: cart.items.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(cart.items[index].name),
);
},
);
},
);
}
}
```
### Riverpod Pattern
```dart
// Provider definition
final userProvider = FutureProvider<User>((ref) async {
final repository = ref.read(userRepositoryProvider);
return repository.fetchCurrentUser();
});
final counterProvider = StateNotifierProvider<CounterNotifier, int>((ref) {
return CounterNotifier();
});
class CounterNotifier extends StateNotifier<int> {
CounterNotifier() : super(0);
void increment() => state++;
void decrement() => state--;
}
// Consumer widget
class UserProfile extends ConsumerWidget {
const UserProfile({super.key});
@override
Widget build(BuildContext context, WidgetRef ref) {
final userAsync = ref.watch(userProvider);
return userAsync.when(
data: (user) => Text('Hello, ${user.name}'),
loading: () => const CircularProgressIndicator(),
error: (error, stack) => Text('Error: $error'),
);
}
}
```
### BLoC Pattern
```dart
// Events
abstract class CounterEvent {}
class IncrementEvent extends CounterEvent {}
class DecrementEvent extends CounterEvent {}
// State
class CounterState {
final int count;
const CounterState(this.count);
}
// BLoC
class CounterBloc extends Bloc<CounterEvent, CounterState> {
CounterBloc() : super(const CounterState(0)) {
on<IncrementEvent>((event, emit) {
emit(CounterState(state.count + 1));
});
on<DecrementEvent>((event, emit) {
emit(CounterState(state.count - 1));
});
}
}
// Usage
class CounterPage extends StatelessWidget {
const CounterPage({super.key});
@override
Widget build(BuildContext context) {
return BlocBuilder<CounterBloc, CounterState>(
builder: (context, state) {
return Text('Count: ${state.count}');
},
);
}
}
```
## Testing
### Unit Tests
```dart
import 'package:test/test.dart';
void main() {
group('Calculator', () {
late Calculator calculator;
setUp(() {
calculator = Calculator();
});
test('adds two positive numbers', () {
expect(calculator.add(2, 3), equals(5));
});
test('handles negative numbers', () {
expect(calculator.add(-1, 1), equals(0));
});
});
}
```
### Widget Tests
```dart
import 'package:flutter_test/flutter_test.dart';
void main() {
testWidgets('Counter increments', (WidgetTester tester) async {
// Build widget
await tester.pumpWidget(const MaterialApp(home: Counter()));
// Verify initial state
expect(find.text('Count: 0'), findsOneWidget);
// Tap increment button
await tester.tap(find.byIcon(Icons.add));
await tester.pump();
// Verify incremented state
expect(find.text('Count: 1'), findsOneWidget);
});
testWidgets('shows loading indicator', (WidgetTester tester) async {
await tester.pumpWidget(
const MaterialApp(
home: UserProfile(isLoading: true),
),
);
expect(find.byType(CircularProgressIndicator), findsOneWidget);
});
}
```
### Mocking
```dart
import 'package:mockito/mockito.dart';
import 'package:mockito/annotations.dart';
@GenerateMocks([UserRepository])
void main() {
late MockUserRepository mockRepository;
late UserService service;
setUp(() {
mockRepository = MockUserRepository();
service = UserService(mockRepository);
});
test('fetches user by id', () async {
final user = User(id: 1, name: 'John');
when(mockRepository.findById(1)).thenAnswer((_) async => user);
final result = await service.getUser(1);
expect(result, equals(user));
verify(mockRepository.findById(1)).called(1);
});
}
```
## Common Patterns
### Factory Constructors
```dart
class User {
final int id;
final String name;
final String email;
const User({
required this.id,
required this.name,
required this.email,
});
// Factory from JSON
factory User.fromJson(Map<String, dynamic> json) {
return User(
id: json['id'] as int,
name: json['name'] as String,
email: json['email'] as String,
);
}
// Factory for default user
factory User.guest() {
return const User(
id: 0,
name: 'Guest',
email: 'guest@example.com',
);
}
Map<String, dynamic> toJson() {
return {
'id': id,
'name': name,
'email': email,
};
}
}
```
### Extension Methods
```dart
extension StringExtensions on String {
String capitalize() {
if (isEmpty) return this;
return '${this[0].toUpperCase()}${substring(1)}';
}
bool get isValidEmail {
return RegExp(r'^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$').hasMatch(this);
}
}
extension DateTimeExtensions on DateTime {
String get formatted => '${day.toString().padLeft(2, '0')}/'
'${month.toString().padLeft(2, '0')}/$year';
bool get isToday {
final now = DateTime.now();
return year == now.year && month == now.month && day == now.day;
}
}
// Usage
final name = 'john'.capitalize(); // 'John'
final isValid = 'test@example.com'.isValidEmail; // true
```
### Sealed Classes (Dart 3)
```dart
sealed class Result<T> {}
class Success<T> extends Result<T> {
final T data;
Success(this.data);
}
class Error<T> extends Result<T> {
final String message;
Error(this.message);
}
class Loading<T> extends Result<T> {}
// Usage with exhaustive pattern matching
Widget buildResult(Result<User> result) {
return switch (result) {
Success(data: final user) => Text(user.name),
Error(message: final msg) => Text('Error: $msg'),
Loading() => const CircularProgressIndicator(),
};
}
```
### Freezed for Immutable Data
```dart
import 'package:freezed_annotation/freezed_annotation.dart';
part 'user.freezed.dart';
part 'user.g.dart';
@freezed
class User with _$User {
const factory User({
required int id,
required String name,
required String email,
@Default(false) bool isActive,
}) = _User;
factory User.fromJson(Map<String, dynamic> json) => _$UserFromJson(json);
}
// Usage
final user = User(id: 1, name: 'John', email: 'john@example.com');
final updatedUser = user.copyWith(name: 'Jane');
```

# General Code Style Guide
Universal coding principles that apply across all languages and frameworks.
## Readability
### Code is Read More Than Written
- Write code for humans first, computers second
- Favor clarity over cleverness
- If code needs a comment to explain what it does, consider rewriting it
### Formatting
- Consistent indentation (use project standard)
- Reasonable line length (80-120 characters)
- Logical grouping with whitespace
- One statement per line
### Structure
- Keep functions/methods short (ideally < 20 lines)
- One level of abstraction per function
- Early returns to reduce nesting
- Group related code together
## Naming Conventions
### General Principles
- Names should reveal intent
- Avoid abbreviations (except universally understood ones)
- Be consistent within codebase
- Length proportional to scope
### Variables
```
# Bad
d = 86400 # What is this?
temp = getUserData() # Temp what?
# Good
secondsPerDay = 86400
userData = getUserData()
```
### Functions/Methods
- Use verbs for actions: `calculateTotal()`, `validateInput()`
- Use `is/has/can` for booleans: `isValid()`, `hasPermission()`
- Be specific: `sendEmailNotification()` not `send()`
### Constants
- Use SCREAMING_SNAKE_CASE or language convention
- Group related constants
- Document magic numbers
### Classes/Types
- Use nouns: `User`, `OrderProcessor`, `ValidationResult`
- Avoid generic names: `Manager`, `Handler`, `Data`
## Comments
### When to Comment
- WHY, not WHAT (code shows what, comments explain why)
- Complex algorithms or business logic
- Non-obvious workarounds with references
- Public API documentation
### When NOT to Comment
- Obvious code
- Commented-out code (delete it)
- Change history (use git)
- TODOs without tickets (create tickets instead)
### Comment Quality
```
# Bad
i += 1 # Increment i
# Good
# Retry limit based on SLA requirements (see JIRA-1234)
maxRetries = 3
```
## Error Handling
### Principles
- Fail fast and explicitly
- Handle errors at appropriate level
- Preserve error context
- Log for debugging, throw for callers
### Patterns
```
# Bad: Silent failure
try:
result = riskyOperation()
except:
pass
# Good: Explicit handling
try:
result = riskyOperation()
except SpecificError as e:
logger.error(f"Operation failed: {e}")
raise OperationFailed("Unable to complete operation") from e
```
### Error Messages
- Be specific about what failed
- Include relevant context
- Suggest remediation when possible
- Avoid exposing internal details to users
## Functions and Methods
### Single Responsibility
- One function = one task
- If you need "and" to describe it, split it
- Extract helper functions for clarity
### Parameters
- Limit parameters (ideally ≤ 3)
- Use objects/structs for many parameters
- Avoid boolean parameters (use named options)
- Order: required first, optional last
### Return Values
- Return early for edge cases
- Consistent return types
- Avoid returning null/nil when possible
- Consider Result/Option types for failures
## Code Organization
### File Structure
- One primary concept per file
- Related helpers in same file or nearby
- Consistent file naming
- Logical directory structure
### Import/Dependency Order
1. Standard library
2. External dependencies
3. Internal dependencies
4. Local/relative imports
### Coupling and Cohesion
- High cohesion within modules
- Low coupling between modules
- Depend on abstractions, not implementations
- Avoid circular dependencies
## Testing Considerations
### Testable Code
- Pure functions where possible
- Dependency injection
- Avoid global state
- Small, focused functions
### Test Naming
```
# Describe behavior, not implementation
test_user_can_login_with_valid_credentials()
test_order_total_includes_tax_and_shipping()
```
## Security Basics
### Input Validation
- Validate all external input
- Sanitize before use
- Whitelist over blacklist
- Fail closed (deny by default)
### Secrets
- Never hardcode secrets
- Use environment variables or secret managers
- Don't log sensitive data
- Rotate credentials regularly
### Data Handling
- Minimize data collection
- Encrypt sensitive data
- Secure data in transit and at rest
- Follow principle of least privilege
## Performance Mindset
### Premature Optimization
- Make it work, then make it fast
- Measure before optimizing
- Optimize bottlenecks, not everything
- Document performance-critical code
### Common Pitfalls
- N+1 queries
- Unnecessary allocations in loops
- Missing indexes
- Synchronous operations that could be async
## Code Review Checklist
- [ ] Does it work correctly?
- [ ] Is it readable and maintainable?
- [ ] Are edge cases handled?
- [ ] Is error handling appropriate?
- [ ] Are there security concerns?
- [ ] Is it tested adequately?
- [ ] Does it follow project conventions?
- [ ] Is there unnecessary complexity?

# Go Style Guide
Go idioms and conventions for clean, maintainable code.
## gofmt and Standard Formatting
### Always Use gofmt
```bash
# Format a single file
gofmt -w file.go
# Format entire project
gofmt -w .
# Use goimports for imports management
goimports -w .
```
### Formatting Rules (Enforced by gofmt)
- Tabs for indentation
- No trailing whitespace
- Consistent brace placement
- Standardized spacing
## Error Handling
### Explicit Error Checking
```go
// Always check errors explicitly
file, err := os.Open(filename)
if err != nil {
return fmt.Errorf("opening file %s: %w", filename, err)
}
defer file.Close()
// Don't ignore errors with _
// Bad
data, _ := json.Marshal(obj)
// Good
data, err := json.Marshal(obj)
if err != nil {
return nil, fmt.Errorf("marshaling object: %w", err)
}
```
### Error Wrapping
```go
// Use %w to wrap errors for unwrapping later
func processFile(path string) error {
data, err := os.ReadFile(path)
if err != nil {
return fmt.Errorf("reading file %s: %w", path, err)
}
if err := validate(data); err != nil {
return fmt.Errorf("validating data: %w", err)
}
return nil
}
// Check wrapped errors
if errors.Is(err, os.ErrNotExist) {
// Handle file not found
}
var validationErr *ValidationError
if errors.As(err, &validationErr) {
// Handle validation error
}
```
### Custom Error Types
```go
// Sentinel errors for expected conditions
var (
ErrNotFound = errors.New("resource not found")
ErrUnauthorized = errors.New("unauthorized access")
ErrInvalidInput = errors.New("invalid input")
)
// Custom error type with additional context
type ValidationError struct {
Field string
Message string
}
func (e *ValidationError) Error() string {
return fmt.Sprintf("validation error on %s: %s", e.Field, e.Message)
}
// Error constructor
func NewValidationError(field, message string) error {
return &ValidationError{Field: field, Message: message}
}
```
## Interfaces
### Small, Focused Interfaces
```go
// Good: Single-method interface
type Reader interface {
Read(p []byte) (n int, err error)
}
type Writer interface {
Write(p []byte) (n int, err error)
}
// Compose interfaces
type ReadWriter interface {
Reader
Writer
}
// Bad: Large interfaces
type Repository interface {
Find(id string) (*User, error)
FindAll() ([]*User, error)
Create(user *User) error
Update(user *User) error
Delete(id string) error
FindByEmail(email string) (*User, error)
// Too many methods - hard to implement and test
}
```
### Accept Interfaces, Return Structs
```go
// Good: Accept interface, return concrete type
func NewUserService(repo UserRepository) *UserService {
return &UserService{repo: repo}
}
// Interface defined by consumer
type UserRepository interface {
Find(ctx context.Context, id string) (*User, error)
Save(ctx context.Context, user *User) error
}
// Concrete implementation
type PostgresUserRepo struct {
db *sql.DB
}
func (r *PostgresUserRepo) Find(ctx context.Context, id string) (*User, error) {
// Implementation
}
```
### Interface Naming
```go
// Single-method interfaces: method name + "er"
type Reader interface { Read(p []byte) (n int, err error) }
type Writer interface { Write(p []byte) (n int, err error) }
type Closer interface { Close() error }
type Stringer interface { String() string }
// Multi-method interfaces: descriptive name
type UserStore interface {
Get(ctx context.Context, id string) (*User, error)
Put(ctx context.Context, user *User) error
}
```
## Package Structure
### Standard Layout

```go
// Package names: short, lowercase, no underscores
package user // Good
package userService // Bad
package user_service // Bad
// Package comment at top of primary file
// Package user provides user management functionality.
package user
// Group imports: stdlib, external, internal
import (
"context"
"fmt"
"github.com/google/uuid"
"github.com/lib/pq"
"myproject/internal/config"
)
```
### Internal Packages
```go
// internal/ packages cannot be imported from outside the module
// Use for implementation details you don't want to expose
// myproject/internal/cache/cache.go
package cache
// This can only be imported by code in myproject/
```
## Testing
### Test File Organization
```go
// user_test.go - same package
package user
import (
"testing"
)
func TestUserValidation(t *testing.T) {
// Test implementation details
}
// user_integration_test.go - external test package
package user_test
import (
"testing"
"myproject/internal/user"
)
func TestUserService(t *testing.T) {
// Test public API
}
```
### Table-Driven Tests
```go
func TestAdd(t *testing.T) {
tests := []struct {
name string
a, b int
expected int
}{
{"positive numbers", 2, 3, 5},
{"negative numbers", -1, -1, -2},
{"mixed numbers", -1, 5, 4},
{"zeros", 0, 0, 0},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
result := Add(tt.a, tt.b)
if result != tt.expected {
t.Errorf("Add(%d, %d) = %d; want %d",
tt.a, tt.b, result, tt.expected)
}
})
}
}
```
### Test Helpers
```go
// Helper functions should call t.Helper()
func newTestUser(t *testing.T) *User {
t.Helper()
return &User{
ID: uuid.New().String(),
Name: "Test User",
Email: "test@example.com",
}
}
func assertNoError(t *testing.T, err error) {
t.Helper()
if err != nil {
t.Fatalf("unexpected error: %v", err)
}
}
func assertEqual[T comparable](t *testing.T, got, want T) {
t.Helper()
if got != want {
t.Errorf("got %v; want %v", got, want)
}
}
```
### Mocking with Interfaces
```go
// Define interface for dependency
type UserRepository interface {
Find(ctx context.Context, id string) (*User, error)
Save(ctx context.Context, user *User) error
}
// Mock implementation for testing
type mockUserRepo struct {
users map[string]*User
}
func newMockUserRepo() *mockUserRepo {
return &mockUserRepo{users: make(map[string]*User)}
}
func (m *mockUserRepo) Find(ctx context.Context, id string) (*User, error) {
user, ok := m.users[id]
if !ok {
return nil, ErrNotFound
}
return user, nil
}
func (m *mockUserRepo) Save(ctx context.Context, user *User) error {
m.users[user.ID] = user
return nil
}
// Test using mock
func TestUserService_GetUser(t *testing.T) {
repo := newMockUserRepo()
repo.users["123"] = &User{ID: "123", Name: "Test"}
service := NewUserService(repo)
user, err := service.GetUser(context.Background(), "123")
assertNoError(t, err)
assertEqual(t, user.Name, "Test")
}
```
## Common Patterns
### Options Pattern
```go
// Option function type
type ServerOption func(*Server)
// Option functions
func WithPort(port int) ServerOption {
return func(s *Server) {
s.port = port
}
}
func WithTimeout(timeout time.Duration) ServerOption {
return func(s *Server) {
s.timeout = timeout
}
}
func WithLogger(logger *slog.Logger) ServerOption {
return func(s *Server) {
s.logger = logger
}
}
// Constructor using options
func NewServer(opts ...ServerOption) *Server {
s := &Server{
port: 8080, // defaults
timeout: 30 * time.Second,
logger: slog.Default(),
}
for _, opt := range opts {
opt(s)
}
return s
}
// Usage
server := NewServer(
WithPort(9000),
WithTimeout(time.Minute),
)
```
### Context Usage
```go
// Always pass context as first parameter
func (s *Service) ProcessRequest(ctx context.Context, req *Request) (*Response, error) {
// Check for cancellation
select {
case <-ctx.Done():
return nil, ctx.Err()
default:
}
// Use context for timeouts
ctx, cancel := context.WithTimeout(ctx, 5*time.Second)
defer cancel()
result, err := s.repo.Find(ctx, req.ID)
if err != nil {
return nil, fmt.Errorf("finding item: %w", err)
}
return &Response{Data: result}, nil
}
```
### Defer for Cleanup
```go
func processFile(path string) error {
file, err := os.Open(path)
if err != nil {
return err
}
defer file.Close() // Always executed on return
// Process file...
return nil
}
// Multiple defers execute in LIFO order
func transaction(db *sql.DB) error {
tx, err := db.Begin()
if err != nil {
return err
}
defer tx.Rollback() // Safe: no-op if committed
// Do work...
return tx.Commit()
}
```
### Concurrency Patterns
```go
// Worker pool
func processItems(items []Item, workers int) []Result {
jobs := make(chan Item, len(items))
results := make(chan Result, len(items))
// Start workers
var wg sync.WaitGroup
for i := 0; i < workers; i++ {
wg.Add(1)
go func() {
defer wg.Done()
for item := range jobs {
results <- process(item)
}
}()
}
// Send jobs
for _, item := range items {
jobs <- item
}
close(jobs)
// Wait and collect
go func() {
wg.Wait()
close(results)
}()
var out []Result
for r := range results {
out = append(out, r)
}
return out
}
```
## Code Quality
### Linting with golangci-lint
```yaml
# .golangci.yml
linters:
enable:
- errcheck
- govet
- ineffassign
- staticcheck
- unused
- gosimple
- gocritic
- gofmt
- goimports
linters-settings:
govet:
check-shadowing: true
errcheck:
check-type-assertions: true
issues:
exclude-rules:
- path: _test\.go
linters:
- errcheck
```
### Common Commands
```bash
# Format code
go fmt ./...
# Run linter
golangci-lint run
# Run tests
go test ./...
# Run tests with coverage
go test -coverprofile=coverage.out ./...
go tool cover -html=coverage.out
# Check for race conditions
go test -race ./...
# Build
go build ./...

# HTML & CSS Style Guide
Web standards for semantic markup, maintainable styling, and accessibility.
## Semantic HTML
### Document Structure
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta name="description" content="Page description for SEO" />
<title>Page Title | Site Name</title>
<link rel="stylesheet" href="styles.css" />
</head>
<body>
<header>
<nav aria-label="Main navigation">
<!-- Navigation -->
</nav>
</header>
<main>
<article>
<!-- Primary content -->
</article>
<aside>
<!-- Supplementary content -->
</aside>
</main>
<footer>
<!-- Footer content -->
</footer>
</body>
</html>
```
### Semantic Elements
```html
<!-- Use appropriate semantic elements -->
<!-- Navigation -->
<nav aria-label="Main navigation">
<ul>
<li><a href="/">Home</a></li>
<li><a href="/about">About</a></li>
</ul>
</nav>
<!-- Article with header and footer -->
<article>
<header>
<h1>Article Title</h1>
<time datetime="2024-01-15">January 15, 2024</time>
</header>
<p>Article content...</p>
<footer>
<p>Written by <address>Author Name</address></p>
</footer>
</article>
<!-- Sections with headings -->
<section aria-labelledby="features-heading">
<h2 id="features-heading">Features</h2>
<p>Section content...</p>
</section>
<!-- Figures with captions -->
<figure>
<img src="chart.png" alt="Sales data showing 20% growth">
<figcaption>Q4 2024 Sales Performance</figcaption>
</figure>
<!-- Definition lists -->
<dl>
<dt>HTML</dt>
<dd>HyperText Markup Language</dd>
<dt>CSS</dt>
<dd>Cascading Style Sheets</dd>
</dl>
```
### Form Elements
```html
<form action="/submit" method="POST">
<!-- Text input with label -->
<div class="form-group">
<label for="email">Email Address</label>
<input
type="email"
id="email"
name="email"
required
autocomplete="email"
aria-describedby="email-hint"
/>
<span id="email-hint" class="hint">We'll never share your email.</span>
</div>
<!-- Select with label -->
<div class="form-group">
<label for="country">Country</label>
<select id="country" name="country" required>
<option value="">Select a country</option>
<option value="us">United States</option>
<option value="uk">United Kingdom</option>
</select>
</div>
<!-- Radio group with fieldset -->
<fieldset>
<legend>Preferred Contact Method</legend>
<div>
<input type="radio" id="contact-email" name="contact" value="email" />
<label for="contact-email">Email</label>
</div>
<div>
<input type="radio" id="contact-phone" name="contact" value="phone" />
<label for="contact-phone">Phone</label>
</div>
</fieldset>
<!-- Submit button -->
<button type="submit">Submit</button>
</form>
```
## BEM Naming Convention
### Block, Element, Modifier
```css
/* Block: Standalone component */
.card {
}
/* Element: Part of block (double underscore) */
.card__header {
}
.card__body {
}
.card__footer {
}
/* Modifier: Variation (double hyphen) */
.card--featured {
}
.card--compact {
}
.card__header--centered {
}
```
### BEM Examples
```html
<!-- Card component -->
<article class="card card--featured">
<header class="card__header">
<h2 class="card__title">Card Title</h2>
</header>
<div class="card__body">
<p class="card__text">Card content goes here.</p>
</div>
<footer class="card__footer">
<button class="card__button card__button--primary">Action</button>
</footer>
</article>
<!-- Navigation component -->
<nav class="nav nav--horizontal">
<ul class="nav__list">
<li class="nav__item nav__item--active">
<a class="nav__link" href="/">Home</a>
</li>
<li class="nav__item">
<a class="nav__link" href="/about">About</a>
</li>
</ul>
</nav>
```
### BEM Best Practices
```css
/* Avoid deep nesting */
/* Bad */
.card__header__title__icon {
}
/* Good - flatten structure */
.card__title-icon {
}
/* Avoid styling elements without class */
/* Bad */
.card h2 {
}
/* Good */
.card__title {
}
/* Modifiers extend base styles */
.button {
padding: 8px 16px;
border-radius: 4px;
}
.button--large {
padding: 12px 24px;
}
.button--primary {
background: blue;
color: white;
}
```
## Accessibility
### ARIA Attributes
```html
<!-- Live regions for dynamic content -->
<div aria-live="polite" aria-atomic="true">Status updates appear here</div>
<!-- Landmarks -->
<nav aria-label="Main navigation"></nav>
<nav aria-label="Footer navigation"></nav>
<!-- Current page in navigation -->
<a href="/about" aria-current="page">About</a>
<!-- Expanded/collapsed state -->
<button aria-expanded="false" aria-controls="menu">Toggle Menu</button>
<div id="menu" hidden>Menu content</div>
<!-- Disabled vs aria-disabled -->
<button disabled>Can't click (removed from tab order)</button>
<button aria-disabled="true">Can't click (stays in tab order)</button>
<!-- Loading states -->
<button aria-busy="true">
<span aria-hidden="true">Loading...</span>
<span class="visually-hidden">Please wait</span>
</button>
```
### Keyboard Navigation
```html
<!-- Skip link -->
<a href="#main-content" class="skip-link">Skip to main content</a>
<!-- Focusable elements should be obvious -->
<style>
:focus-visible {
outline: 2px solid blue;
outline-offset: 2px;
}
</style>
<!-- Tabindex usage -->
<!-- tabindex="0": Add to tab order -->
<div tabindex="0" role="button">Custom button</div>
<!-- tabindex="-1": Programmatically focusable only -->
<div id="modal" tabindex="-1">Modal content</div>
<!-- Never use tabindex > 0 -->
```
### Screen Reader Support
```css
/* Visually hidden but accessible */
.visually-hidden {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0, 0, 0, 0);
white-space: nowrap;
border: 0;
}
/* Hide from screen readers */
[aria-hidden="true"] {
/* Decorative content */
}
```
```html
<!-- Icon buttons need accessible names -->
<button aria-label="Close dialog">
<svg aria-hidden="true"><!-- icon --></svg>
</button>
<!-- Decorative images -->
<img src="decoration.png" alt="" role="presentation" />
<!-- Informative images -->
<img src="chart.png" alt="Sales increased 20% in Q4 2024" />
<!-- Complex images -->
<figure>
<img
src="flowchart.png"
alt="User registration process"
aria-describedby="flowchart-desc"
/>
<figcaption id="flowchart-desc">
Step 1: Enter email. Step 2: Verify email. Step 3: Create password.
</figcaption>
</figure>
```
## Responsive Design
### Mobile-First Approach
```css
/* Base styles for mobile */
.container {
padding: 16px;
}
.grid {
display: grid;
gap: 16px;
grid-template-columns: 1fr;
}
/* Tablet and up */
@media (min-width: 768px) {
.container {
padding: 24px;
}
.grid {
grid-template-columns: repeat(2, 1fr);
}
}
/* Desktop and up */
@media (min-width: 1024px) {
.container {
padding: 32px;
max-width: 1200px;
margin: 0 auto;
}
.grid {
grid-template-columns: repeat(3, 1fr);
}
}
```
### Flexible Units
```css
/* Use relative units */
body {
font-size: 16px; /* Base size */
}
h1 {
font-size: 2rem; /* Relative to root */
margin-bottom: 1em; /* Relative to element */
}
.container {
max-width: 75ch; /* Character width for readability */
padding: 1rem;
}
/* Fluid typography */
h1 {
font-size: clamp(1.5rem, 4vw, 3rem);
}
/* Fluid spacing */
.section {
padding: clamp(2rem, 5vw, 4rem);
}
```
### Responsive Images
```html
<!-- Responsive image with srcset -->
<img
src="image-800.jpg"
srcset="image-400.jpg 400w, image-800.jpg 800w, image-1200.jpg 1200w"
sizes="(max-width: 600px) 100vw, 50vw"
alt="Description"
loading="lazy"
/>
<!-- Art direction with picture -->
<picture>
<source media="(min-width: 1024px)" srcset="hero-desktop.jpg" />
<source media="(min-width: 768px)" srcset="hero-tablet.jpg" />
<img src="hero-mobile.jpg" alt="Hero image" />
</picture>
```
## CSS Best Practices
### Custom Properties (CSS Variables)
```css
:root {
/* Colors */
--color-primary: #0066cc;
--color-primary-dark: #004c99;
--color-secondary: #6c757d;
--color-success: #28a745;
--color-error: #dc3545;
/* Typography */
--font-family-base: system-ui, sans-serif;
--font-family-mono: ui-monospace, monospace;
--font-size-sm: 0.875rem;
--font-size-base: 1rem;
--font-size-lg: 1.25rem;
/* Spacing */
--spacing-xs: 0.25rem;
--spacing-sm: 0.5rem;
--spacing-md: 1rem;
--spacing-lg: 1.5rem;
--spacing-xl: 2rem;
/* Borders */
--border-radius: 4px;
--border-color: #dee2e6;
/* Shadows */
--shadow-sm: 0 1px 2px rgba(0, 0, 0, 0.1);
--shadow-md: 0 4px 6px rgba(0, 0, 0, 0.1);
}
/* Dark mode */
@media (prefers-color-scheme: dark) {
:root {
--color-primary: #4da6ff;
--color-background: #1a1a1a;
--color-text: #ffffff;
}
}
/* Usage */
.button {
background: var(--color-primary);
padding: var(--spacing-sm) var(--spacing-md);
border-radius: var(--border-radius);
}
```
### Modern Layout
```css
/* Flexbox for 1D layouts */
.navbar {
display: flex;
justify-content: space-between;
align-items: center;
gap: var(--spacing-md);
}
/* Grid for 2D layouts */
.page-layout {
display: grid;
grid-template-areas:
"header header"
"sidebar main"
"footer footer";
grid-template-columns: 250px 1fr;
grid-template-rows: auto 1fr auto;
min-height: 100vh;
}
.header {
grid-area: header;
}
.sidebar {
grid-area: sidebar;
}
.main {
grid-area: main;
}
.footer {
grid-area: footer;
}
/* Auto-fit grid */
.card-grid {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
gap: var(--spacing-lg);
}
```
### Performance
```css
/* Avoid expensive properties in animations */
/* Bad - triggers layout */
.animate-bad {
animation: move 1s;
}
@keyframes move {
to {
left: 100px;
top: 100px;
}
}
/* Good - uses transform */
.animate-good {
animation: move-optimized 1s;
}
@keyframes move-optimized {
to {
transform: translate(100px, 100px);
}
}
/* Use will-change sparingly */
.will-animate {
will-change: transform;
}
/* Contain for layout isolation */
.card {
contain: layout style;
}
/* Content-visibility for off-screen content */
.below-fold {
content-visibility: auto;
contain-intrinsic-size: 500px;
}
```
## HTML Best Practices
### Validation and Attributes
```html
<!-- Use proper input types -->
<input type="email" autocomplete="email" />
<input type="tel" autocomplete="tel" />
<input type="url" />
<input type="number" min="0" max="100" step="1" />
<input type="date" min="2024-01-01" />
<!-- Required and validation -->
<input type="text" required minlength="2" maxlength="50" pattern="[A-Za-z]+" />
<!-- Autocomplete for better UX -->
<input type="text" name="name" autocomplete="name" />
<input type="text" name="address" autocomplete="street-address" />
<input type="text" name="cc-number" autocomplete="cc-number" />
```
### Performance Attributes
```html
<!-- Lazy loading -->
<img src="image.jpg" loading="lazy" alt="Description" />
<iframe src="video.html" loading="lazy"></iframe>
<!-- Preload critical resources -->
<link rel="preload" href="critical.css" as="style" />
<link rel="preload" href="hero.jpg" as="image" />
<link rel="preload" href="font.woff2" as="font" crossorigin />
<!-- Preconnect to origins -->
<link rel="preconnect" href="https://api.example.com" />
<link rel="dns-prefetch" href="https://analytics.example.com" />
<!-- Async/defer scripts -->
<script src="analytics.js" async></script>
<script src="app.js" defer></script>
```
### Microdata and SEO
```html
<!-- Schema.org markup -->
<article itemscope itemtype="https://schema.org/Article">
<h1 itemprop="headline">Article Title</h1>
<time itemprop="datePublished" datetime="2024-01-15"> January 15, 2024 </time>
<div itemprop="author" itemscope itemtype="https://schema.org/Person">
<span itemprop="name">Author Name</span>
</div>
<div itemprop="articleBody">Article content...</div>
</article>
<!-- Open Graph for social sharing -->
<meta property="og:title" content="Page Title" />
<meta property="og:description" content="Page description" />
<meta property="og:image" content="https://example.com/image.jpg" />
<meta property="og:url" content="https://example.com/page" />
```

# JavaScript Style Guide
Modern JavaScript (ES6+) best practices and conventions.
## ES6+ Features
### Use Modern Syntax
```javascript
// Prefer const and let over var
const immutableValue = "fixed";
let mutableValue = "can change";
// Never use var
// var outdated = 'avoid this';
// Template literals over concatenation
const greeting = `Hello, ${name}!`;
// Destructuring
const { id, name, email } = user;
const [first, second, ...rest] = items;
// Spread operator
const merged = { ...defaults, ...options };
const combined = [...array1, ...array2];
// Arrow functions for short callbacks
const doubled = numbers.map((n) => n * 2);
```
### Object Shorthand
```javascript
// Property shorthand
const name = "John";
const age = 30;
const user = { name, age };
// Method shorthand
const calculator = {
add(a, b) {
return a + b;
},
subtract(a, b) {
return a - b;
},
};
// Computed property names
const key = "dynamic";
const obj = {
[key]: "value",
[`${key}Method`]() {
return "result";
},
};
```
### Default Parameters and Rest
```javascript
// Default parameters
function greet(name = "Guest", greeting = "Hello") {
return `${greeting}, ${name}!`;
}
// Rest parameters
function sum(...numbers) {
return numbers.reduce((total, n) => total + n, 0);
}
// Named parameters via destructuring
function createUser({ name, email, role = "user" }) {
return { name, email, role, createdAt: new Date() };
}
```
## Async/Await
### Prefer async/await Over Promises
```javascript
// Bad: Promise chains
function fetchUserPosts(userId) {
return fetch(`/users/${userId}`)
.then((res) => res.json())
.then((user) => fetch(`/posts?userId=${user.id}`))
.then((res) => res.json());
}
// Good: async/await
async function fetchUserPosts(userId) {
const userRes = await fetch(`/users/${userId}`);
const user = await userRes.json();
const postsRes = await fetch(`/posts?userId=${user.id}`);
return postsRes.json();
}
```
### Parallel Execution
```javascript
// Sequential (slow)
async function loadDataSequentially() {
const users = await fetchUsers();
const posts = await fetchPosts();
const comments = await fetchComments();
return { users, posts, comments };
}
// Parallel (fast)
async function loadDataParallel() {
const [users, posts, comments] = await Promise.all([
fetchUsers(),
fetchPosts(),
fetchComments(),
]);
return { users, posts, comments };
}
```
### Error Handling
```javascript
// try/catch with async/await
async function fetchData(url) {
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error(`HTTP ${response.status}: ${response.statusText}`);
}
return await response.json();
} catch (error) {
console.error("Fetch failed:", error.message);
throw error;
}
}
// Error handling utility
async function safeAsync(promise) {
try {
const result = await promise;
return [result, null];
} catch (error) {
return [null, error];
}
}
// Usage
const [data, error] = await safeAsync(fetchData("/api/users"));
if (error) {
handleError(error);
}
```
## Error Handling
### Custom Errors
```javascript
class AppError extends Error {
constructor(message, code, statusCode = 500) {
super(message);
this.name = "AppError";
this.code = code;
this.statusCode = statusCode;
Error.captureStackTrace(this, this.constructor);
}
}
class ValidationError extends AppError {
constructor(message, field) {
super(message, "VALIDATION_ERROR", 400);
this.name = "ValidationError";
this.field = field;
}
}
class NotFoundError extends AppError {
constructor(resource, id) {
super(`${resource} with id ${id} not found`, "NOT_FOUND", 404);
this.name = "NotFoundError";
this.resource = resource;
this.resourceId = id;
}
}
```
### Error Handling Patterns
```javascript
// Centralized error handler
function handleError(error) {
if (error instanceof ValidationError) {
showFieldError(error.field, error.message);
} else if (error instanceof NotFoundError) {
showNotFound(error.resource);
} else {
showGenericError("Something went wrong");
reportError(error);
}
}
// Error boundary pattern (for React)
function withErrorBoundary(Component) {
return class extends React.Component {
state = { hasError: false };
static getDerivedStateFromError() {
return { hasError: true };
}
componentDidCatch(error, info) {
reportError(error, info);
}
render() {
if (this.state.hasError) {
return <ErrorFallback />;
}
return <Component {...this.props} />;
}
};
}
```
## Module Patterns
### ES Modules
```javascript
// Named exports
export const API_URL = "/api";
export function fetchData(endpoint) {
/* ... */
}
export class ApiClient {
/* ... */
}
// Re-exports
export { User, Post } from "./types.js";
export * as utils from "./utils.js";
// Imports
import { fetchData, API_URL } from "./api.js";
import * as api from "./api.js";
import defaultExport from "./module.js";
```
### Module Organization
```javascript
// Feature-based organization
// features/user/
// index.js - Public exports
// api.js - API calls
// utils.js - Helper functions
// constants.js - Feature constants
// index.js - Barrel export
export { UserService } from "./service.js";
export { validateUser } from "./utils.js";
export { USER_ROLES } from "./constants.js";
```
### Dependency Injection
```javascript
// Constructor injection
class UserService {
constructor(apiClient, logger) {
this.api = apiClient;
this.logger = logger;
}
async getUser(id) {
this.logger.info(`Fetching user ${id}`);
return this.api.get(`/users/${id}`);
}
}
// Factory function
function createUserService(config = {}) {
const api = config.apiClient || new ApiClient();
const logger = config.logger || console;
return new UserService(api, logger);
}
```
## Functional Patterns
### Pure Functions
```javascript
// Impure: Modifies external state
let count = 0;
function incrementCount() {
count++;
return count;
}
// Pure: No side effects
function increment(value) {
return value + 1;
}
// Pure: Same input = same output
function calculateTotal(items) {
return items.reduce((sum, item) => sum + item.price, 0);
}
```
### Array Methods
```javascript
const users = [
{ id: 1, name: "Alice", active: true },
{ id: 2, name: "Bob", active: false },
{ id: 3, name: "Charlie", active: true },
];
// map - transform
const names = users.map((user) => user.name);
// filter - select
const activeUsers = users.filter((user) => user.active);
// find - first match
const user = users.find((user) => user.id === 2);
// some/every - boolean check
const hasActive = users.some((user) => user.active);
const allActive = users.every((user) => user.active);
// reduce - accumulate
const userMap = users.reduce((map, user) => {
map[user.id] = user;
return map;
}, {});
// Chaining
const activeNames = users
.filter((user) => user.active)
.map((user) => user.name)
.sort();
```
### Composition
```javascript
// Compose functions
const compose =
(...fns) =>
(x) =>
fns.reduceRight((acc, fn) => fn(acc), x);
const pipe =
(...fns) =>
(x) =>
fns.reduce((acc, fn) => fn(acc), x);
// Usage
const processUser = pipe(validateUser, normalizeUser, enrichUser);
const result = processUser(rawUserData);
```
## Classes
### Modern Class Syntax
```javascript
class User {
// Private fields
#password;
// Static properties
static ROLES = ["admin", "user", "guest"];
constructor(name, email) {
this.name = name;
this.email = email;
this.#password = null;
}
// Getter
get displayName() {
return `${this.name} <${this.email}>`;
}
// Setter
set password(value) {
if (value.length < 8) {
throw new Error("Password too short");
}
this.#password = hashPassword(value);
}
// Instance method
toJSON() {
return { name: this.name, email: this.email };
}
// Static method
static fromJSON(json) {
return new User(json.name, json.email);
}
}
```
### Inheritance
```javascript
class Entity {
constructor(id) {
this.id = id;
this.createdAt = new Date();
}
equals(other) {
return other instanceof Entity && this.id === other.id;
}
}
class User extends Entity {
constructor(id, name, email) {
super(id);
this.name = name;
this.email = email;
}
toJSON() {
return {
id: this.id,
name: this.name,
email: this.email,
createdAt: this.createdAt.toISOString(),
};
}
}
```
## Common Patterns
### Null Safety
```javascript
// Optional chaining
const city = user?.address?.city;
const firstItem = items?.[0];
const result = obj?.method?.();
// Nullish coalescing
const name = user.name ?? "Anonymous";
const count = value ?? 0;
// Combining both
const displayName = user?.profile?.name ?? "Unknown";
```
### Debounce and Throttle
```javascript
function debounce(fn, delay) {
let timeoutId;
return function (...args) {
clearTimeout(timeoutId);
timeoutId = setTimeout(() => fn.apply(this, args), delay);
};
}
function throttle(fn, limit) {
let inThrottle;
return function (...args) {
if (!inThrottle) {
fn.apply(this, args);
inThrottle = true;
setTimeout(() => (inThrottle = false), limit);
}
};
}
```
### Memoization
```javascript
function memoize(fn) {
const cache = new Map();
return function (...args) {
const key = JSON.stringify(args);
if (cache.has(key)) {
return cache.get(key);
}
const result = fn.apply(this, args);
cache.set(key, result);
return result;
};
}
// Usage
const expensiveCalculation = memoize((n) => {
// Complex computation
return fibonacci(n);
});
```
## Best Practices
### Avoid Common Pitfalls
```javascript
// Avoid loose equality
// Bad
if (value == null) {
}
// Good
if (value === null || value === undefined) {
}
if (value == null) {
} // Only acceptable for null/undefined check
// Avoid implicit type coercion
// Bad
if (items.length) {
}
// Good
if (items.length > 0) {
}
// Avoid modifying function arguments
// Bad
function process(options) {
options.processed = true;
return options;
}
// Good
function process(options) {
return { ...options, processed: true };
}
```
### Performance Tips
```javascript
// Avoid creating functions in loops
// Bad
items.forEach(function (item) {
item.addEventListener("click", function () {});
});
// Good
function handleClick(event) {}
items.forEach((item) => {
item.addEventListener("click", handleClick);
});
// Use appropriate data structures
// For frequent lookups, use Map/Set instead of Array
const userMap = new Map(users.map((u) => [u.id, u]));
const userIds = new Set(users.map((u) => u.id));

# Python Style Guide
Python conventions following PEP 8 and modern best practices.
## PEP 8 Fundamentals
### Naming Conventions
```python
# Variables and functions: snake_case
user_name = "John"
def calculate_total(items):
pass
# Constants: SCREAMING_SNAKE_CASE
MAX_CONNECTIONS = 100
DEFAULT_TIMEOUT = 30
# Classes: PascalCase
class UserAccount:
pass
# Private: single underscore prefix
class User:
def __init__(self):
self._internal_state = {}
# Name mangling: double underscore prefix
class Base:
def __init__(self):
self.__private = "truly private"
# Module-level "private": single underscore
_module_cache = {}
```
### Indentation and Line Length
```python
# 4 spaces per indentation level
def function():
if condition:
do_something()
# Line length: 88 characters (Black) or 79 (PEP 8)
# Break long lines appropriately
result = some_function(
argument_one,
argument_two,
argument_three,
)
# Implicit line continuation in brackets
users = [
"alice",
"bob",
"charlie",
]
```
### Imports
```python
# Standard library
import os
import sys
from pathlib import Path
from typing import Optional, List
# Third-party
import requests
from pydantic import BaseModel
# Local application
from myapp.models import User
from myapp.utils import format_date
# Avoid wildcard imports
# Bad: from module import *
# Good: from module import specific_item
```
## Type Hints
### Basic Type Annotations
```python
from typing import Optional, List, Dict, Tuple, Union, Any
# Variables
name: str = "John"
age: int = 30
active: bool = True
scores: List[int] = [90, 85, 92]
# Functions
def greet(name: str) -> str:
return f"Hello, {name}!"
def find_user(user_id: int) -> Optional[User]:
"""Returns User or None if not found."""
pass
def process_items(items: List[str]) -> Dict[str, int]:
"""Returns count of each item."""
pass
```
### Advanced Type Hints
```python
from typing import (
TypeVar, Generic, Protocol, Callable,
Literal, TypedDict, Final
)
# TypeVar for generics
T = TypeVar('T')
def first(items: List[T]) -> Optional[T]:
return items[0] if items else None
# Protocol for structural typing
class Renderable(Protocol):
def render(self) -> str: ...
def display(obj: Renderable) -> None:
print(obj.render())
# Literal for specific values
Status = Literal["pending", "active", "completed"]
def set_status(status: Status) -> None:
pass
# TypedDict for dictionary shapes
class UserDict(TypedDict):
id: int
name: str
email: Optional[str]
# Final for constants
MAX_SIZE: Final = 100
```
### Type Hints in Classes
```python
from dataclasses import dataclass
from typing import ClassVar, Self
@dataclass
class User:
id: int
name: str
email: str
active: bool = True
# Class variable
_instances: ClassVar[Dict[int, 'User']] = {}
def deactivate(self) -> Self:
self.active = False
return self
class Builder:
def __init__(self) -> None:
self._value: str = ""
def append(self, text: str) -> Self:
self._value += text
return self
```
## Docstrings
### Function Docstrings
```python
def calculate_discount(
price: float,
discount_percent: float,
min_price: float = 0.0
) -> float:
"""Calculate the discounted price.
Args:
price: Original price of the item.
discount_percent: Discount percentage (0-100).
min_price: Minimum price floor. Defaults to 0.0.
Returns:
The discounted price, not less than min_price.
Raises:
ValueError: If discount_percent is not between 0 and 100.
Example:
>>> calculate_discount(100.0, 20.0)
80.0
"""
if not 0 <= discount_percent <= 100:
raise ValueError("Discount must be between 0 and 100")
discounted = price * (1 - discount_percent / 100)
return max(discounted, min_price)
```
### Class Docstrings
```python
class UserService:
"""Service for managing user operations.
This service handles user CRUD operations and authentication.
It requires a database connection and optional cache.
Attributes:
db: Database connection instance.
cache: Optional cache for user lookups.
Example:
>>> service = UserService(db_connection)
>>> user = service.get_user(123)
"""
def __init__(
self,
db: DatabaseConnection,
cache: Optional[Cache] = None
) -> None:
"""Initialize the UserService.
Args:
db: Active database connection.
cache: Optional cache instance for performance.
"""
self.db = db
self.cache = cache
```

```
## Testing
### pytest Basics
```python
import pytest
from myapp.calculator import add, divide
def test_add_positive_numbers():
assert add(2, 3) == 5
def test_add_negative_numbers():
assert add(-1, -1) == -2
def test_divide_by_zero_raises():
with pytest.raises(ZeroDivisionError):
divide(10, 0)
# Parametrized tests
@pytest.mark.parametrize("a,b,expected", [
(1, 1, 2),
(0, 0, 0),
(-1, 1, 0),
])
def test_add_parametrized(a, b, expected):
assert add(a, b) == expected
```
### Fixtures
```python
import pytest
from myapp.database import Database
from myapp.models import User
@pytest.fixture
def db():
"""Provide a clean database for each test."""
database = Database(":memory:")
database.create_tables()
yield database
database.close()
@pytest.fixture
def sample_user(db):
"""Create a sample user in the database."""
user = User(name="Test User", email="test@example.com")
db.save(user)
return user
def test_user_creation(db, sample_user):
found = db.find_user(sample_user.id)
assert found.name == "Test User"
```
### Mocking
```python
from unittest.mock import Mock, patch, MagicMock
import pytest
def test_api_client_with_mock():
# Create mock
mock_response = Mock()
mock_response.json.return_value = {"id": 1, "name": "Test"}
mock_response.status_code = 200
with patch('requests.get', return_value=mock_response) as mock_get:
result = fetch_user(1)
mock_get.assert_called_once_with('/users/1')
assert result['name'] == "Test"
@patch('myapp.service.external_api')
def test_with_patch_decorator(mock_api):
mock_api.get_data.return_value = {"status": "ok"}
result = process_data()
assert result["status"] == "ok"
```
## Error Handling
### Exception Patterns
```python
# Define custom exceptions
class AppError(Exception):
"""Base exception for application errors."""
pass
class ValidationError(AppError):
"""Raised when validation fails."""
def __init__(self, field: str, message: str):
self.field = field
self.message = message
super().__init__(f"{field}: {message}")
class NotFoundError(AppError):
"""Raised when a resource is not found."""
def __init__(self, resource: str, identifier: Any):
self.resource = resource
self.identifier = identifier
super().__init__(f"{resource} '{identifier}' not found")
```
### Exception Handling
```python
def get_user(user_id: int) -> User:
try:
user = db.find_user(user_id)
if user is None:
raise NotFoundError("User", user_id)
return user
except DatabaseError as e:
logger.error(f"Database error: {e}")
raise AppError("Unable to fetch user") from e
# Context managers for cleanup
from contextlib import contextmanager
@contextmanager
def database_transaction(db):
try:
yield db
db.commit()
except Exception:
db.rollback()
raise
```
## Common Patterns
### Dataclasses
```python
from dataclasses import dataclass, field
from typing import List, Optional
from datetime import datetime
@dataclass
class User:
id: int
name: str
email: str
active: bool = True
created_at: datetime = field(default_factory=datetime.now)
tags: List[str] = field(default_factory=list)
def __post_init__(self):
self.email = self.email.lower()
@dataclass(frozen=True)
class Point:
"""Immutable point."""
x: float
y: float
def distance_to(self, other: 'Point') -> float:
return ((self.x - other.x)**2 + (self.y - other.y)**2) ** 0.5
```
### Context Managers
```python
from contextlib import contextmanager
from typing import Generator
@contextmanager
def timer(name: str) -> Generator[None, None, None]:
"""Time a block of code."""
import time
start = time.perf_counter()
try:
yield
finally:
elapsed = time.perf_counter() - start
print(f"{name}: {elapsed:.3f}s")
# Usage
with timer("data processing"):
process_large_dataset()
# Class-based context manager
class DatabaseConnection:
def __init__(self, connection_string: str):
self.connection_string = connection_string
self.connection = None
def __enter__(self):
self.connection = connect(self.connection_string)
return self.connection
def __exit__(self, exc_type, exc_val, exc_tb):
if self.connection:
self.connection.close()
return False # Don't suppress exceptions
```
### Decorators
```python
from functools import wraps
from typing import Callable, TypeVar, ParamSpec
import time
P = ParamSpec('P')
R = TypeVar('R')
def retry(max_attempts: int = 3, delay: float = 1.0):
"""Retry decorator with exponential backoff."""
def decorator(func: Callable[P, R]) -> Callable[P, R]:
@wraps(func)
def wrapper(*args: P.args, **kwargs: P.kwargs) -> R:
last_exception = None
for attempt in range(max_attempts):
try:
return func(*args, **kwargs)
except Exception as e:
last_exception = e
if attempt < max_attempts - 1:
time.sleep(delay * (2 ** attempt))
raise last_exception
return wrapper
return decorator
@retry(max_attempts=3, delay=0.5)
def fetch_data(url: str) -> dict:
response = requests.get(url)
response.raise_for_status()
return response.json()
```
## Code Quality Tools
### Ruff Configuration
```toml
# pyproject.toml
[tool.ruff]
line-length = 88
target-version = "py311"
[tool.ruff.lint]
select = [
"E", # pycodestyle errors
"W", # pycodestyle warnings
"F", # Pyflakes
"I", # isort
"B", # flake8-bugbear
"C4", # flake8-comprehensions
"UP", # pyupgrade
]
ignore = ["E501"] # Line too long (handled by formatter)
[tool.ruff.lint.isort]
known-first-party = ["myapp"]
```
### Type Checking with mypy
```toml
# pyproject.toml
[tool.mypy]
python_version = "3.11"
strict = true
warn_return_any = true
warn_unused_configs = true
ignore_missing_imports = true
```

# TypeScript Style Guide
TypeScript-specific conventions and best practices for type-safe development.
## Strict Mode
### Enable Strict Configuration
```json
{
"compilerOptions": {
"strict": true,
"noImplicitAny": true,
"strictNullChecks": true,
"strictFunctionTypes": true,
"strictBindCallApply": true,
"strictPropertyInitialization": true,
"noImplicitThis": true,
"alwaysStrict": true,
"noUncheckedIndexedAccess": true,
"noImplicitReturns": true,
"noFallthroughCasesInSwitch": true
}
}
```
### Benefits
- Catches errors at compile time
- Better IDE support and autocomplete
- Self-documenting code
- Easier refactoring
## Type Safety
### Avoid `any`
```typescript
// Bad
function processData(data: any): any {
return data.value;
}
// Good
interface DataItem {
value: string;
count: number;
}
function processData(data: DataItem): string {
return data.value;
}
```
### Use `unknown` for Unknown Types
```typescript
// When type is truly unknown
function parseJSON(json: string): unknown {
return JSON.parse(json);
}
// Then narrow with type guards
function isUser(obj: unknown): obj is User {
return (
typeof obj === "object" && obj !== null && "id" in obj && "name" in obj
);
}
```
### Prefer Explicit Types
```typescript
// Bad: Implicit any
const items = [];
// Good: Explicit type
const items: Item[] = [];
// Also good: Type inference when obvious
const count = 0; // number inferred
const name = "John"; // string inferred
```
## Interfaces vs Types
### Use Interfaces for Object Shapes
```typescript
// Preferred for objects
interface User {
id: string;
name: string;
email: string;
}
// Interfaces can be extended
interface AdminUser extends User {
permissions: string[];
}
// Interfaces can be augmented (declaration merging)
interface User {
avatar?: string;
}
```
### Use Types for Unions, Primitives, and Computed Types
```typescript
// Union types
type Status = "pending" | "active" | "completed";
// Primitive aliases
type UserId = string;
// Computed/mapped types
type Readonly<T> = {
readonly [P in keyof T]: T[P];
};
// Tuple types
type Coordinate = [number, number];
```
### Decision Guide
| Use Case | Recommendation |
| ----------------------- | -------------- |
| Object shape | `interface` |
| Union type | `type` |
| Function signature | `type` |
| Class implementation | `interface` |
| Mapped/conditional type | `type` |
| Library public API | `interface` |
## Async Patterns
### Prefer async/await
```typescript
// Bad: Callback hell
function fetchUserData(id: string, callback: (user: User) => void) {
fetch(`/users/${id}`)
.then((res) => res.json())
.then((user) => callback(user));
}
// Good: async/await
async function fetchUserData(id: string): Promise<User> {
const response = await fetch(`/users/${id}`);
return response.json();
}
```
### Error Handling in Async Code
```typescript
// Explicit error handling
async function fetchUser(id: string): Promise<User> {
try {
const response = await fetch(`/users/${id}`);
if (!response.ok) {
throw new ApiError(`Failed to fetch user: ${response.status}`);
}
return response.json();
} catch (error) {
if (error instanceof ApiError) {
throw error;
}
throw new NetworkError("Network request failed", { cause: error });
}
}
```
### Promise Types
```typescript
// Return type annotation for clarity
async function loadData(): Promise<Data[]> {
// ...
}
// Use Promise.all for parallel operations
async function loadAllData(): Promise<[Users, Posts]> {
return Promise.all([fetchUsers(), fetchPosts()]);
}
```
## Module Structure
### File Organization
```
src/
├── types/ # Shared type definitions
│ ├── user.ts
│ └── api.ts
├── utils/ # Pure utility functions
│ ├── validation.ts
│ └── formatting.ts
├── services/ # Business logic
│ ├── userService.ts
│ └── authService.ts
├── components/ # UI components (if applicable)
└── index.ts # Public API exports
```
### Export Patterns
```typescript
// Named exports (preferred)
export interface User { ... }
export function createUser(data: UserInput): User { ... }
export const DEFAULT_USER: User = { ... };
// Re-exports for public API
// index.ts
export { User, createUser } from './user';
export { type Config } from './config';
// Avoid default exports (harder to refactor)
// Bad
export default class UserService { ... }
// Good
export class UserService { ... }
```
### Import Organization
```typescript
// 1. External dependencies
import { useState, useEffect } from "react";
import { z } from "zod";
// 2. Internal absolute imports
import { ApiClient } from "@/services/api";
import { User } from "@/types";
// 3. Relative imports
import { formatDate } from "./utils";
import { UserCard } from "./UserCard";
```
## Utility Types
### Built-in Utility Types
```typescript
// Partial - all properties optional
type UpdateUser = Partial<User>;
// Required - all properties required
type CompleteUser = Required<User>;
// Pick - select properties
type UserPreview = Pick<User, "id" | "name">;
// Omit - exclude properties
type UserWithoutPassword = Omit<User, "password">;
// Record - dictionary type
type UserRoles = Record<string, Role>;
// ReturnType - extract return type
type ApiResponse = ReturnType<typeof fetchData>;
// Parameters - extract parameter types
type FetchParams = Parameters<typeof fetch>;
```
### Custom Utility Types
```typescript
// Make specific properties optional
type PartialBy<T, K extends keyof T> = Omit<T, K> & Partial<Pick<T, K>>;
// Make specific properties required
type RequiredBy<T, K extends keyof T> = Omit<T, K> & Required<Pick<T, K>>;
// Deep readonly
type DeepReadonly<T> = {
readonly [P in keyof T]: T[P] extends object ? DeepReadonly<T[P]> : T[P];
};
```
## Enums and Constants
### Prefer const Objects Over Enums
```typescript
// Enums have runtime overhead
enum Status {
Pending = "pending",
Active = "active",
}
// Prefer const objects
const Status = {
Pending: "pending",
Active: "active",
} as const;
type Status = (typeof Status)[keyof typeof Status];
```
### When to Use Enums
```typescript
// Numeric enums for bit flags
enum Permissions {
None = 0,
Read = 1 << 0,
Write = 1 << 1,
Execute = 1 << 2,
All = Read | Write | Execute,
}
```
## Generics
### Basic Generic Usage
```typescript
// Generic function
function first<T>(items: T[]): T | undefined {
return items[0];
}
// Generic interface
interface Repository<T> {
find(id: string): Promise<T | null>;
save(item: T): Promise<T>;
delete(id: string): Promise<void>;
}
```
### Constraining Generics
```typescript
// Constrain to objects with id
function findById<T extends { id: string }>(
items: T[],
id: string,
): T | undefined {
return items.find((item) => item.id === id);
}
// Multiple constraints
function merge<T extends object, U extends object>(a: T, b: U): T & U {
return { ...a, ...b };
}
```
## Error Types
### Custom Error Classes
```typescript
class AppError extends Error {
constructor(
message: string,
public readonly code: string,
public readonly statusCode: number = 500,
) {
super(message);
this.name = "AppError";
}
}
class ValidationError extends AppError {
constructor(
message: string,
public readonly field: string,
) {
super(message, "VALIDATION_ERROR", 400);
this.name = "ValidationError";
}
}
```
### Type Guards for Errors
```typescript
function isAppError(error: unknown): error is AppError {
return error instanceof AppError;
}
function handleError(error: unknown): void {
if (isAppError(error)) {
console.error(`[${error.code}] ${error.message}`);
} else if (error instanceof Error) {
console.error(`Unexpected error: ${error.message}`);
} else {
console.error("Unknown error occurred");
}
}
```
## Testing Types
### Type Testing
```typescript
// Use type assertions for compile-time checks
type Assert<T, U extends T> = U;
// Test that types work as expected
type _TestUserHasId = Assert<{ id: string }, User>;
// Expect error (compile-time check)
// @ts-expect-error - User should require id
const invalidUser: User = { name: "John" };
```
## Common Patterns
### Builder Pattern
```typescript
class QueryBuilder<T> {
private filters: Array<(item: T) => boolean> = [];
where(predicate: (item: T) => boolean): this {
this.filters.push(predicate);
return this;
}
execute(items: T[]): T[] {
return items.filter((item) => this.filters.every((filter) => filter(item)));
}
}
```
### Result Type
```typescript
type Result<T, E = Error> =
| { success: true; data: T }
| { success: false; error: E };
function divide(a: number, b: number): Result<number> {
if (b === 0) {
return { success: false, error: new Error("Division by zero") };
}
return { success: true, data: a / b };
}
```

## Accessibility Standards
### Compliance Target
{{ACCESSIBILITY_STANDARD}} (e.g., WCAG 2.1 AA)
### Core Requirements
#### Perceivable
- All images have meaningful alt text
- Color is not the only means of conveying information
- Text has minimum contrast ratio of 4.5:1
- Content is readable at 200% zoom
#### Operable
- All functionality available via keyboard
- No content flashes more than 3 times per second
- Skip navigation links provided
- Focus indicators clearly visible
#### Understandable
- Language is clear and simple
- Navigation is consistent
- Error messages are descriptive and helpful
- Labels and instructions are clear
#### Robust
- Valid HTML markup
- ARIA labels used appropriately
- Compatible with assistive technologies
- Progressive enhancement approach
### Testing Requirements
- Screen reader testing with {{SCREEN_READER}}
- Keyboard-only navigation testing
- Color contrast verification
- Automated accessibility scans
## Error Handling Philosophy
### Error Prevention
- Validate input early and often
- Provide clear constraints and requirements upfront
- Use inline validation where appropriate
- Confirm destructive actions
### Error Communication
#### Principles
1. **Be specific:** Tell users exactly what went wrong
2. **Be helpful:** Explain how to fix the problem
3. **Be human:** Use friendly, non-technical language
4. **Be timely:** Show errors as soon as they're detected
#### Error Message Structure
```
[What happened] + [Why it happened (if relevant)] + [How to fix it]
```
#### Examples
| Bad | Good |
| --------------- | ---------------------------------------------------- |
| "Invalid input" | "Email address must include @ symbol" |
| "Error 500" | "We couldn't save your changes. Please try again." |
| "Failed" | "Unable to connect. Check your internet connection." |
### Error States
| Severity | Visual Treatment | User Action Required |
| -------- | ---------------------- | -------------------- |
| Info | {{INFO_TREATMENT}} | Optional |
| Warning | {{WARNING_TREATMENT}} | Recommended |
| Error | {{ERROR_TREATMENT}} | Required |
| Critical | {{CRITICAL_TREATMENT}} | Immediate |
### Recovery Patterns
- Auto-save user progress where possible
- Provide clear "try again" actions
- Offer alternative paths when primary fails
- Preserve user input on errors

# Track Registry
This file maintains the registry of all development tracks for the project. Each track represents a distinct body of work with its own spec and implementation plan.
## Status Legend
| Symbol | Status | Description |
| ------ | ----------- | ------------------------- |
| `[ ]` | Pending | Not yet started |
| `[~]` | In Progress | Currently being worked on |
| `[x]` | Completed | Finished and verified |
## Active Tracks
### [ ] {{TRACK_ID}}: {{TRACK_NAME}}
**Description:** {{TRACK_DESCRIPTION}}
**Priority:** {{PRIORITY}}
**Folder:** [./tracks/{{TRACK_ID}}/](./tracks/{{TRACK_ID}}/)
---
### [ ] {{TRACK_ID}}: {{TRACK_NAME}}
**Description:** {{TRACK_DESCRIPTION}}
**Priority:** {{PRIORITY}}
**Folder:** [./tracks/{{TRACK_ID}}/](./tracks/{{TRACK_ID}}/)
---
## Completed Tracks
<!-- Move completed tracks here -->
---
## Track Creation Checklist
When creating a new track:
1. [ ] Add entry to this registry
2. [ ] Create track folder: `./tracks/{{track-id}}/`
3. [ ] Create spec.md from template
4. [ ] Create plan.md from template
5. [ ] Create metadata.json from template
6. [ ] Update index.md with new track reference
## Notes
- Track IDs should be lowercase with hyphens (e.g., `user-auth`, `api-v2`)
- Keep descriptions concise (one line)
- Prioritize tracks as: critical, high, medium, low
- Archive completed tracks quarterly

# Development Workflow
## Core Principles
1. **plan.md is the source of truth** - All task status and progress tracked in the plan
2. **Test-Driven Development** - Red → Green → Refactor cycle with 80% coverage target
3. **CI/CD Compatibility** - All changes must pass automated pipelines before merge
4. **Incremental Progress** - Small, verifiable commits with clear purpose
## Task Lifecycle
### Step 1: Task Selection
- Review plan.md for next pending task
- Verify dependencies are complete
- Confirm understanding of acceptance criteria
### Step 2: Progress Marking
- Update task status in plan.md from `[ ]` to `[~]`
- Note start time if tracking velocity
### Step 3: Red Phase (Write Failing Tests)
- Write test(s) that define expected behavior
- Verify test fails for the right reason
- Keep tests focused and minimal
### Step 4: Green Phase (Make Tests Pass)
- Write minimum code to pass tests
- Avoid premature optimization
- Focus on correctness over elegance
### Step 5: Refactor Phase
- Improve code structure without changing behavior
- Apply relevant style guide conventions
- Remove duplication and clarify intent
### Step 6: Coverage Verification
- Run coverage report
- Ensure new code meets 80% threshold
- Add edge case tests if coverage gaps exist
### Step 7: Deviation Documentation
- If implementation differs from spec, document why
- Update spec if change is permanent
- Flag for review if uncertain
### Step 8: Code Commit
- Stage related changes only
- Write clear commit message referencing task
- Format: `[track-id] task: description`
### Step 9: Git Notes (Optional)
- Add implementation notes for complex changes
- Reference relevant decisions or trade-offs
### Step 10: Plan Update
- Mark task as `[x]` completed in plan.md
- Update any affected downstream tasks
- Note blockers or follow-up items
### Step 11: Plan Commit
- Commit plan.md changes separately
- Format: `[track-id] plan: mark task X complete`
## Phase Completion Protocol
### Checkpoint Commits
At the end of each phase:
1. Ensure all phase tasks are `[x]` complete
2. Run full test suite
3. Verify coverage meets threshold
4. Create checkpoint commit: `[track-id] checkpoint: phase N complete`
### Test Verification
```bash
{{TEST_COMMAND}}
{{COVERAGE_COMMAND}}
```
### Manual Approval Gates
Phases requiring approval before proceeding:
- Architecture changes
- API contract modifications
- Database schema changes
- Security-sensitive implementations
## Quality Assurance Gates
All code must pass these criteria before merge:
| Gate | Requirement | Command |
| ----------- | ------------------------ | ------------------------ |
| 1. Tests | All tests passing | `{{TEST_COMMAND}}` |
| 2. Coverage | Minimum 80% | `{{COVERAGE_COMMAND}}` |

## Plugin Design Principles
### Single Responsibility
- Each plugin does **one thing well** (Unix philosophy)
- Clear, focused purposes (describable in 5-10 words)
- Average plugin size: **3.4 components** (follows Anthropic's 2-8 pattern)
### Minimal Token Usage
- Install only what you need
- Each plugin loads only its specific agents and tools
- No unnecessary resources loaded into context
- Better context efficiency with granular plugins
### Composability
- Mix and match plugins for complex workflows
- Workflow orchestrators compose focused plugins
- Clear boundaries between plugins

### Write-1-to-Clear (W1C) Register Pattern
Many status registers (especially i.MX RT, STM32) clear by writing 1, not 0:
```cpp

**Common W1C:** `USBSTS`, `PORTSC`, CCM status. **Wrong:** `status &= ~bit` does nothing on W1C registers.
### Platform Safety & Gotchas

- Most platforms: GPIO max 3.3V (NOT 5V tolerant except STM32 FT pins)
- Use level shifters for 5V interfaces

## The Problem
Analysis of churned customers reveals a pattern:
- 73% churned within first 90 days
- Common factor: < 3 support interactions
- Low feature adoption in first month
## The Insight
[Show engagement curve visualization]
Customers who don't engage in the first 14 days

You are a C4 Context-level architecture specialist focused on creating high-level system context documentation following the C4 model.
## Purpose
Expert in synthesizing Container and Component-level documentation with system documentation, test files, and requirements to create comprehensive Context-level architecture documentation. Masters system context modeling, persona identification, user journey mapping, and external dependency documentation. Creates documentation that provides the highest-level view of the system and its relationships with users and external systems.
## Core Philosophy
According to the [C4 model](https://c4model.com/diagrams/system-context), context diagrams show the system as a box in the center, surrounded by its users and the other systems that it interacts with. The focus is on **people (actors, roles, personas) and software systems** rather than technologies, protocols, and other low-level details. Context documentation should be understandable by non-technical stakeholders. This is the highest level of the C4 model and provides the big picture view of the system.
