-Each subagent is defined as a Markdown file with frontmatter:
-
-```markdown
----
-name: subagent-name
-description: Activation criteria for this subagent
-model: haiku|sonnet|opus # Optional: Model selection
-tools: tool1, tool2 # Optional: Tool restrictions
----
-
-System prompt defining the subagent's expertise and behavior
-```
-

-- **haiku**: Simple, deterministic tasks with minimal reasoning
-- **sonnet**: Standard development and engineering tasks
-- **opus**: Complex analysis, architecture, and critical operations
-
-## Agent Orchestration Patterns
+## Multi-Agent Orchestration Patterns
### Sequential Processing
-Agents execute in sequence, passing context forward:
```
backend-architect → frontend-developer → test-automator → security-auditor
```
### Parallel Execution
-Multiple agents work simultaneously on different aspects:
```
-performance-engineer + database-optimizer → Merged analysis
+performance-engineer + database-optimizer → Merged optimization
```
### Conditional Routing
-Dynamic agent selection based on analysis:
```
debugger → [backend-architect | frontend-developer | devops-troubleshooter]
```
### Validation Pipeline
-Primary work followed by specialized review:
```
-payment-integration → security-auditor → Validated implementation
+feature-development → security-auditor → performance-engineer → Validated release
```

-## Best Practices
-
-### Task Delegation
-1. **Automatic selection** - Let Claude Code analyze context and select optimal agents
-2. **Clear requirements** - Specify constraints, tech stack, and quality standards
-3. **Trust specialization** - Each agent is optimized for their specific domain
-
-### Multi-Agent Workflows
-1. **High-level requests** - Allow agents to coordinate complex multi-step tasks
-2. **Context preservation** - Ensure agents have necessary background information
-3. **Integration review** - Verify how different agents' outputs work together
-
-### Explicit Control
-1. **Direct invocation** - Specify agents when you need particular expertise
-2. **Strategic combination** - Use multiple specialists for validation
-3. **Review patterns** - Request specific review workflows (e.g., "security-auditor reviews API design")
-
-### Performance Optimization
-1. **Monitor effectiveness** - Track which agents work best for your use cases
-2. **Iterative refinement** - Use agent feedback to improve requirements
-3. **Complexity matching** - Align task complexity with agent capabilities

+To add new agents, workflows, or tools:
-1. Create a new `.md` file with appropriate frontmatter
-2. Use lowercase, hyphen-separated naming convention
-3. Write clear activation criteria in the description
-4. Define comprehensive system prompt with expertise areas
-
-## Troubleshooting
-
-### Agent Not Activating
-- Ensure request clearly indicates the domain
-- Be specific about task type and requirements
-- Use explicit invocation if automatic selection fails
-
-### Unexpected Agent Selection
-- Provide more context about tech stack
-- Include specific requirements in request
-- Use direct agent naming for precise control
-
-### Conflicting Recommendations
-- Normal behavior - specialists have different priorities
-- Request reconciliation between specific agents
-- Consider trade-offs based on project requirements
-
-### Missing Context
-- Include background information in requests
-- Reference previous work or patterns
-- Provide project-specific constraints
+1. Place agent definitions in `agents/` directory
+2. Place workflow orchestrators in `workflows/` directory
+3. Place tool commands in `tools/` directory
+4. Follow existing naming conventions (lowercase, hyphen-separated)
+5. Include proper frontmatter in markdown files

+## Installation
+
+Clone the repository to the Claude agents directory:
+
+```bash
+cd ~/.claude
+git clone https://github.com/wshobson/agents.git
+```
+
+The subagents will be automatically available to Claude Code once placed in the `~/.claude/agents/` directory.
+
+## Usage
+
+### Automatic Delegation
+Claude Code automatically selects the appropriate subagent based on task context and requirements. The system analyzes your request and delegates to the most suitable specialist.
+
+### Explicit Invocation
+Specify a subagent by name to use a particular specialist:
+
+```
+"Use code-reviewer to analyze the recent changes"
+"Have security-auditor scan for vulnerabilities"
+"Get performance-engineer to optimize this bottleneck"
+```
+
+## Usage Examples
+
+### Code Quality & Security
+```
+code-reviewer: Analyze component for best practices
+security-auditor: Check for OWASP compliance
+tdd-orchestrator: Implement feature with test-first approach
+performance-engineer: Profile and optimize bottlenecks
+```
+
+### Development & Architecture
+```
+backend-architect: Design authentication API
+frontend-developer: Create responsive dashboard
+graphql-architect: Design federated GraphQL schema
+mobile-developer: Build cross-platform mobile app
+```
+
+### Infrastructure & Operations
+```
+devops-troubleshooter: Analyze production logs
+cloud-architect: Design scalable AWS architecture
+network-engineer: Debug SSL certificate issues
+database-admin: Configure backup and replication
+terraform-specialist: Write infrastructure modules
+```
+
+### Data & Machine Learning
+```

+ai-engineer: Build RAG system for document search
+mlops-engineer: Set up experiment tracking
+ml-engineer: Deploy model to production
+```
+
+### Business & Documentation
+```
+business-analyst: Create metrics dashboard
+docs-architect: Generate technical documentation
+api-documenter: Write OpenAPI specifications
+content-marketer: Create SEO-optimized content
+```
+
+## Multi-Agent Workflows
+
+Subagents coordinate automatically for complex tasks. The system intelligently sequences multiple specialists based on task requirements.
+
+### Common Workflow Patterns
+
+**Feature Development**
+```
+"Implement user authentication"
+→ backend-architect → frontend-developer → test-automator → security-auditor
+```
+
+**Performance Optimization**
+```
+"Optimize checkout process"
+→ performance-engineer → database-optimizer → frontend-developer
+```
+
+**Production Incidents**
+```
+"Debug high memory usage"
+→ incident-responder → devops-troubleshooter → error-detective → performance-engineer
+```
+
+**Infrastructure Setup**
+```
+"Set up disaster recovery"
+→ database-admin → database-optimizer → terraform-specialist
+```
+
+**ML Pipeline Development**
+```
+"Build ML pipeline with monitoring"
+→ mlops-engineer → ml-engineer → data-engineer → performance-engineer
+```
+
+### Integration with Claude Code Commands
+
+For sophisticated multi-agent orchestration, use the [Claude Code Commands](https://github.com/wshobson/commands) collection which provides 52 pre-built slash commands:
+
+```
+/full-stack-feature # Coordinates 8+ agents for complete feature development
+/incident-response # Activates incident management workflow
+/ml-pipeline # Sets up end-to-end ML infrastructure
+/security-hardening # Implements security best practices across stack
+```
+
+## Subagent Format
+
+Each subagent is defined as a Markdown file with frontmatter:
+
+```markdown
+---
+name: subagent-name
+description: Activation criteria for this subagent
+model: haiku|sonnet|opus # Optional: Model selection
+tools: tool1, tool2 # Optional: Tool restrictions
+---
+
+System prompt defining the subagent's expertise and behavior
+```
+
+### Model Selection Criteria
+
+- **haiku**: Simple, deterministic tasks with minimal reasoning
+- **sonnet**: Standard development and engineering tasks
+- **opus**: Complex analysis, architecture, and critical operations
+
+## Agent Orchestration Patterns
+
+### Sequential Processing
+Agents execute in sequence, passing context forward:
+```
+backend-architect → frontend-developer → test-automator → security-auditor
+```
+
+### Parallel Execution
+Multiple agents work simultaneously on different aspects:
+```
+performance-engineer + database-optimizer → Merged analysis
+```
+
+### Conditional Routing
+Dynamic agent selection based on analysis:
+```
+debugger → [backend-architect | frontend-developer | devops-troubleshooter]
+```
+
+### Validation Pipeline
+Primary work followed by specialized review:
+```
+payment-integration → security-auditor → Validated implementation
+```

+
+You are an accessibility expert specializing in WCAG compliance, inclusive design, and assistive technology compatibility. Conduct comprehensive audits, identify barriers, provide remediation guidance, and ensure digital products are accessible to all users.
+
+## Context
+The user needs to audit and improve accessibility to ensure compliance with WCAG standards and provide an inclusive experience for users with disabilities. Focus on automated testing, manual verification, remediation strategies, and establishing ongoing accessibility practices.
+
+## Requirements
+$ARGUMENTS
+
+## Instructions
+
+### 1. Automated Accessibility Testing
+
+Implement comprehensive automated testing:
+
+**Accessibility Test Suite**
+```javascript

+
+# Run accessibility tests on changed components
+CHANGED_FILES=$(git diff --cached --name-only --diff-filter=ACM | grep -E '\.(jsx?|tsx?)$')
+
+if [ -n "$CHANGED_FILES" ]; then
+ echo "Running accessibility tests on changed files..."
+ npm run test:a11y -- $CHANGED_FILES
+
+ if [ $? -ne 0 ]; then
+ echo "❌ Accessibility tests failed. Please fix issues before committing."
+ exit 1
+ fi
+fi
+```

+
+## Cross-Command Integration
+
+This command integrates seamlessly with other Claude Code commands to create complete development workflows:
+
+### 1. Complete API Development Workflow
+
+**Standard Development Pipeline:**
+```bash
+# 1. Start with API scaffold
+/api-scaffold "User management API with FastAPI, PostgreSQL, and JWT auth"
+
+# 2. Set up comprehensive testing
+/test-harness "FastAPI API with unit, integration, and load testing using pytest and locust"
+
+# 3. Security validation
+/security-scan "FastAPI application with authentication endpoints"
+
+# 4. Container optimization
+/docker-optimize "FastAPI application with PostgreSQL and Redis dependencies"
+
+# 5. Kubernetes deployment
+/k8s-manifest "FastAPI microservice with PostgreSQL, Redis, and ingress"
+
+# 6. Frontend integration (if needed)
+/frontend-optimize "React application connecting to FastAPI backend"
+```
+
+### 2. Database-First Development
+
+**When starting with existing data:**
+```bash
+# 1. Handle database migrations first
+/db-migrate "PostgreSQL schema migration from legacy system to modern structure"
+
+# 2. Generate API based on migrated schema
+/api-scaffold "REST API for migrated PostgreSQL schema with auto-generated models"
+
+# 3. Continue with standard pipeline...
+```
+
+### 3. Microservices Architecture
+
+**For distributed systems:**
+```bash
+# Generate multiple related APIs
+/api-scaffold "User service with authentication and profile management"
+/api-scaffold "Order service with payment processing and inventory"
+/api-scaffold "Notification service with email and push notifications"
+
+# Containerize all services
+/docker-optimize "Microservices architecture with service discovery"
+
+# Deploy as distributed system
+/k8s-manifest "Microservices deployment with service mesh and monitoring"
+```
+
+### 4. Integration with Generated Code
+
+**Test Integration Setup:**
+```yaml
+# After running /api-scaffold, use this with /test-harness
+test_config:
+ api_base_url: "http://localhost:8000"
+ test_database: "postgresql://test:test@localhost:5432/test_db"
+ authentication:
+ test_user: "test@example.com"
+ test_password: "testpassword123"
+
+ endpoints_to_test:
+ - POST /api/v1/users/
+ - POST /api/v1/auth/login
+ - GET /api/v1/users/me
+ - GET /api/v1/users/{id}
+```
+
+**Security Scan Configuration:**
+```yaml
+# Configuration for /security-scan after API scaffold
+security_scan:
+ target: "localhost:8000"
+ authentication_endpoints:
+ - "/api/v1/auth/login"
+ - "/api/v1/auth/refresh"
+ protected_endpoints:
+ - "/api/v1/users/me"
+ - "/api/v1/users/{id}"
+ vulnerability_tests:
+ - jwt_token_validation
+ - sql_injection
+ - xss_prevention
+ - rate_limiting
+```
+
+**Docker Integration:**
+```dockerfile
+# Generated Dockerfile can be optimized with /docker-optimize
+# Multi-stage build for FastAPI application
+FROM python:3.11-slim as builder
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install --user -r requirements.txt
+
+FROM python:3.11-slim as runtime
+WORKDIR /app

+COPY . .
+ENV PATH=/root/.local/bin:$PATH
+CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8000"]
+```
+
+**Kubernetes Deployment:**
+```yaml
+# Use this configuration with /k8s-manifest
+apiVersion: apps/v1
+kind: Deployment

+ path: /ready
+ port: 8000
+ initialDelaySeconds: 5
+ periodSeconds: 5
+```
+
+### 5. CI/CD Pipeline Integration
+
+**Complete pipeline using multiple commands:**
+```yaml
+name: Full Stack CI/CD
+
+on:
+ push:
+ branches: [main]
+
+jobs:
+ api-test:
+ runs-on: ubuntu-latest
+ steps:
+ - uses: actions/checkout@v4
+
+ # Test API (generated by /api-scaffold)
+ - name: Run API tests

+ docker build -f Dockerfile.optimized -t api:${{ github.sha }} .
+
+ # Deploy to Kubernetes (from /k8s-manifest)
+ - name: Deploy to staging
+ run: |
+ kubectl apply -f k8s/staging/
+ kubectl set image deployment/api-deployment api=api:${{ github.sha }}
+```
+
+### 6. Frontend-Backend Integration
+
+**When building full-stack applications:**
+```bash
+# 1. Backend API
+/api-scaffold "REST API with user management and data operations"
+
+# 2. Frontend application
+/frontend-optimize "React SPA with API integration, authentication, and state management"
+
+# 3. Integration testing
+/test-harness "End-to-end testing for React frontend and FastAPI backend"
+
+# 4. Unified deployment
+/k8s-manifest "Full-stack deployment with API, frontend, and database"
+```
+
+**Frontend API Integration Code:**
+```typescript
+// Generated API client for frontend
+// Use this pattern with /frontend-optimize
+export class APIClient {
+ private baseURL: string;
+ private token: string | null = null;
+
+ constructor(baseURL: string) {
+ this.baseURL = baseURL;
+ }
+
+ setAuthToken(token: string) {
+ this.token = token;
+ }
+
+ private async request(
+ endpoint: string,
+ options: RequestInit = {}
+ ): Promise {
+ const url = `${this.baseURL}${endpoint}`;
+ const headers = {
+ 'Content-Type': 'application/json',
+ ...(this.token && { Authorization: `Bearer ${this.token}` }),
+ ...options.headers,
+ };
+
+ const response = await fetch(url, {
+ ...options,
+ headers,
+ });
+
+ if (!response.ok) {
+ throw new Error(`API Error: ${response.statusText}`);
+ }
+
+ return response.json();
+ }
+
+ // User management methods (matching API scaffold)
+ async createUser(userData: CreateUserRequest): Promise {
+ return this.request('/api/v1/users/', {
+ method: 'POST',
+ body: JSON.stringify(userData),
+ });
+ }
+
+ async login(credentials: LoginRequest): Promise {
+ return this.request('/api/v1/auth/login', {
+ method: 'POST',
+ body: JSON.stringify(credentials),
+ });
+ }
+
+ async getCurrentUser(): Promise {
+ return this.request('/api/v1/users/me');
+ }
+}
+```
+
+### 7. Monitoring and Observability Integration
+
+**Complete observability stack:**
+```bash
+# After API deployment, add monitoring
+/api-scaffold "Monitoring endpoints with Prometheus metrics and health checks"
+
+# Use with Kubernetes monitoring
+/k8s-manifest "Kubernetes deployment with Prometheus, Grafana, and alerting"
+```
+
+This integrated approach ensures all components work together seamlessly, creating a production-ready system with proper testing, security, deployment, and monitoring.

+## Understanding Decorators
+
+Decorators are a way to modify or enhance functions without changing their code directly.
+
+**Simple Analogy**: Think of a decorator like gift wrapping - it adds something extra around the original item.
+
+**How it works**:
+```python
+# This decorator:
+@timer
+def slow_function():
+ time.sleep(1)
+
+# Is equivalent to:
+def slow_function():
+ time.sleep(1)
+slow_function = timer(slow_function)
+```

+**In this code**: The decorator is used to {specific_use_in_code}
+''',
+ 'generators': '''
+## Understanding Generators
+
+Generators produce values one at a time, saving memory by not creating all values at once.
+
+**Simple Analogy**: Like a ticket dispenser that gives one ticket at a time, rather than printing all tickets upfront.
+
+**How it works**:
+```python
+# Generator function
+def count_up_to(n):
+ i = 0
+ while i < n:
+ yield i # Produces one value and pauses
+ i += 1
+
+# Using the generator

+
+Visualize algorithm execution:

+**Algorithm Step Visualization**
+```python

+ def visualize_sorting_algorithm(self, algorithm_name, array):
+ """
+ Create step-by-step visualization of sorting algorithm

+### Benefits:
+✅ Controlled access to single instance
+✅ Reduced namespace pollution
+✅ Permits refinement of operations
+
+### Drawbacks:
+❌ Can make unit testing difficult
+❌ Violates Single Responsibility Principle
+❌ Can hide dependencies
+
+### Alternative Approaches:

+Migrate between API paradigms:
+
+**REST to GraphQL Migration**
+```javascript

+Debug complex issues using specialized debugging agents:
+
+[Extended thinking: This tool command leverages the debugger agent with additional support from performance-engineer when performance issues are involved. It provides deep debugging capabilities with root cause analysis.]
+
+## Debugging Approach
+
+### 1. Primary Debug Analysis
+Use Task tool with subagent_type="debugger" to:
+- Analyze error messages and stack traces
+- Identify code paths leading to the issue
+- Reproduce the problem systematically
+- Isolate the root cause
+- Suggest multiple fix approaches
+
+Prompt: "Debug issue: $ARGUMENTS. Provide detailed analysis including:
+1. Error reproduction steps
+2. Root cause identification
+3. Code flow analysis leading to the error
+4. Multiple solution approaches with trade-offs
+5. Recommended fix with implementation details"
+
+### 2. Performance Debugging (if performance-related)
+If the issue involves performance problems, also use Task tool with subagent_type="performance-engineer" to:
+- Profile code execution
+- Identify bottlenecks
+- Analyze resource usage
+- Suggest optimization strategies
+
+Prompt: "Profile and debug performance issue: $ARGUMENTS. Include:
+1. Performance metrics and profiling data
+2. Bottleneck identification
+3. Resource usage analysis
+4. Optimization recommendations
+5. Before/after performance projections"
+
+## Debug Output Structure
+
+### Root Cause Analysis
+- Precise identification of the bug source
+- Explanation of why the issue occurs
+- Impact analysis on other components
+
+### Reproduction Guide
+- Step-by-step reproduction instructions
+- Required environment setup
+- Test data or conditions needed
+
+### Solution Options
+1. **Quick Fix** - Minimal change to resolve issue
+ - Implementation details
+ - Risk assessment
+
+2. **Proper Fix** - Best long-term solution
+ - Refactoring requirements
+ - Testing needs
+
+3. **Preventive Measures** - Avoid similar issues
+ - Code patterns to adopt
+ - Tests to add
+
+### Implementation Guide
+- Specific code changes needed
+- Order of operations for the fix
+- Validation steps
+
+Issue to debug: $ARGUMENTS

+# Standup Notes Generator
+
+Generate daily standup notes by reviewing Obsidian vault context and Jira tickets.
+
+## Usage
+```
+/standup-notes
+```
+
+## Prerequisites
+
+- Enable the **mcp-obsidian** provider with read/write access to the target vault.
+- Configure the **atlassian** provider with Jira credentials that can query the team's backlog.
+- Optional: connect calendar integrations if you want meetings to appear automatically.
+
+## Process
+
+1. **Gather Context from Obsidian**
+ - Use `mcp__mcp-obsidian__obsidian_get_recent_changes` to find recently modified files
+ - Use `mcp__mcp-obsidian__obsidian_get_recent_periodic_notes` to get recent daily notes
+ - Look for project updates, completed tasks, and ongoing work
+
+2. **Check Jira Tickets**
+ - Use `mcp__atlassian__searchJiraIssuesUsingJql` to find tickets assigned to current user (fall back to asking the user for updates if the Atlassian connector is unavailable)
+ - Filter for:
+ - In Progress tickets (current work)
+ - Recently resolved/closed tickets (yesterday's accomplishments)
+ - Upcoming/todo tickets (today's planned work)
+
+3. **Generate Standup Notes**
+ Format:
+ ```
+ Morning!
+ Yesterday:
+
+ • [Completed tasks from Jira and Obsidian notes]
+ • [Key accomplishments and milestones]
+
+ Today:
+
+ • [In-progress Jira tickets]
+ • [Planned work from tickets and notes]
+ • [Meetings from calendar/notes]
+
+ Note: [Any blockers, dependencies, or important context]
+ ```
+
+4. **Write to Obsidian**
+ - Create file in `Standup Notes/YYYY-MM-DD.md` format (or summarize in the chat if the Obsidian connector is disabled)
+ - Use `mcp__mcp-obsidian__obsidian_append_content` to write the generated notes when available
+
+## Implementation Steps
+
+1. Get current user info from Atlassian
+2. Search for recent Obsidian changes (last 2 days)
+3. Query Jira for:
+ - `assignee = currentUser() AND (status CHANGED FROM "In Progress" TO "Done" DURING (-1d, now()) OR resolutiondate >= -1d)`
+ - `assignee = currentUser() AND status = "In Progress"`
+ - `assignee = currentUser() AND status in ("To Do", "Open") AND (sprint in openSprints() OR priority in (High, Highest))`
+4. Parse and categorize findings
+5. Generate formatted standup notes
+6. Save to Obsidian vault
+
+## Context Extraction Patterns
+
+- Look for keywords: "completed", "finished", "deployed", "released", "fixed", "implemented"
+- Extract meeting notes and action items
+- Identify blockers or dependencies mentioned
+- Pull sprint goals and objectives

+Implement minimal code to make failing tests pass in TDD green phase:
+
+[Extended thinking: This tool uses the test-automator agent to implement the minimal code necessary to make tests pass. It focuses on simplicity, avoiding over-engineering while ensuring all tests become green.]
+
+## Implementation Process
+
+Use Task tool with subagent_type="test-automator" to implement minimal passing code.
+
+Prompt: "Implement MINIMAL code to make these failing tests pass: $ARGUMENTS. Follow TDD green phase principles:
+
+1. **Pre-Implementation Analysis**
+ - Review all failing tests and their error messages
+ - Identify the simplest path to make tests pass
+ - Map test requirements to minimal implementation needs
+ - Avoid premature optimization or over-engineering
+ - Focus only on making tests green, not perfect code
+
+2. **Implementation Strategy**
+ - **Fake It**: Return hard-coded values when appropriate
+ - **Obvious Implementation**: When solution is trivial and clear
+ - **Triangulation**: Generalize only when multiple tests require it
+ - Start with the simplest test and work incrementally
+ - One test at a time - don't try to pass all at once
+
+3. **Code Structure Guidelines**
+ - Write the minimal code that could possibly work
+ - Avoid adding functionality not required by tests
+ - Use simple data structures initially
+ - Defer architectural decisions until refactor phase
+ - Keep methods/functions small and focused
+ - Don't add error handling unless tests require it
+
+4. **Language-Specific Patterns**
+ - **JavaScript/TypeScript**: Simple functions, avoid classes initially
+ - **Python**: Functions before classes, simple returns
+ - **Java**: Minimal class structure, no patterns yet
+ - **C#**: Basic implementations, no interfaces yet
+ - **Go**: Simple functions, defer goroutines/channels
+ - **Ruby**: Procedural before object-oriented when possible
+
+5. **Progressive Implementation**
+ - Make first test pass with simplest possible code
+ - Run tests after each change to verify progress
+ - Add just enough code for next failing test
+ - Resist urge to implement beyond test requirements
+ - Keep track of technical debt for refactor phase
+ - Document assumptions and shortcuts taken
+
+6. **Common Green Phase Techniques**
+ - Hard-coded returns for initial tests
+ - Simple if/else for limited test cases
+ - Basic loops only when iteration tests require
+ - Minimal data structures (arrays before complex objects)
+ - In-memory storage before database integration
+ - Synchronous before asynchronous implementation
+
+7. **Success Criteria**
+ ✓ All tests pass (green)
+ ✓ No extra functionality beyond test requirements
+ ✓ Code is readable even if not optimal
+ ✓ No broken existing functionality
+ ✓ Implementation time is minimized
+ ✓ Clear path to refactoring identified
+
+8. **Anti-Patterns to Avoid**
+ - Gold plating or adding unrequested features
+ - Implementing design patterns prematurely
+ - Complex abstractions without test justification
+ - Performance optimizations without metrics
+ - Adding tests during green phase
+ - Refactoring during implementation
+ - Ignoring test failures to move forward
+
+9. **Implementation Metrics**
+ - Time to green: Track implementation duration
+ - Lines of code: Measure implementation size
+ - Cyclomatic complexity: Keep it low initially
+ - Test pass rate: Must reach 100%
+ - Code coverage: Verify all paths tested
+
+10. **Validation Steps**
+ - Run all tests and confirm they pass
+ - Verify no regression in existing tests
+ - Check that implementation is truly minimal
+ - Document any technical debt created
+ - Prepare notes for refactoring phase
+
+Output should include:
+- Complete implementation code
+- Test execution results showing all green
+- List of shortcuts taken for later refactoring
+- Implementation time metrics
+- Technical debt documentation
+- Readiness assessment for refactor phase"
+
+## Post-Implementation Checks
+
+After implementation:
+1. Run full test suite to confirm all tests pass
+2. Verify no existing tests were broken
+3. Document areas needing refactoring
+4. Check implementation is truly minimal
+5. Record implementation time for metrics
+
+## Recovery Process
+
+If tests still fail:
+- Review test requirements carefully
+- Check for misunderstood assertions
+- Add minimal code to address specific failures
+- Avoid the temptation to rewrite from scratch
+- Consider if tests themselves need adjustment
+
+## Integration Points
+
+- Follows from tdd-red.md test creation
+- Prepares for tdd-refactor.md improvements
+- Updates test coverage metrics
+- Triggers CI/CD pipeline verification
+- Documents technical debt for tracking
+
+## Best Practices
+
+- Embrace "good enough" for this phase
+- Speed over perfection (perfection comes in refactor)
+- Make it work, then make it right, then make it fast
+- Trust that refactoring phase will improve code
+- Keep changes small and incremental
+- Celebrate reaching green state!

+Write comprehensive failing tests following TDD red phase principles:
+
+[Extended thinking: This tool uses the test-automator agent to generate comprehensive failing tests that properly define expected behavior. It ensures tests fail for the right reasons and establishes a solid foundation for implementation.]
+
+## Test Generation Process
+
+Use Task tool with subagent_type="test-automator" to generate failing tests.
+
+Prompt: "Generate comprehensive FAILING tests for: $ARGUMENTS. Follow TDD red phase principles:
+
+1. **Test Structure Setup**
+ - Choose appropriate testing framework for the language/stack
+ - Set up test fixtures and necessary imports
+ - Configure test runners and assertion libraries
+ - Establish test naming conventions (should_X_when_Y format)
+
+2. **Behavior Definition**
+ - Define clear expected behaviors from requirements
+ - Cover happy path scenarios thoroughly
+ - Include edge cases and boundary conditions
+ - Add error handling and exception scenarios
+ - Consider null/undefined/empty input cases
+
+3. **Test Implementation**
+ - Write descriptive test names that document intent
+ - Keep tests focused on single behaviors (one assertion per test when possible)
+ - Use Arrange-Act-Assert (AAA) pattern consistently
+ - Implement test data builders for complex objects
+ - Avoid test interdependencies - each test must be isolated
+
+4. **Failure Verification**
+ - Ensure tests actually fail when run
+ - Verify failure messages are meaningful and diagnostic
+ - Confirm tests fail for the RIGHT reasons (not syntax/import errors)
+ - Check that error messages guide implementation
+ - Validate test isolation - no cascading failures
+
+5. **Test Categories**
+ - **Unit Tests**: Isolated component behavior
+ - **Integration Tests**: Component interaction scenarios
+ - **Contract Tests**: API and interface contracts
+ - **Property Tests**: Invariants and mathematical properties
+ - **Acceptance Tests**: User story validation
+
+6. **Framework-Specific Patterns**
+ - **JavaScript/TypeScript**: Jest, Mocha, Vitest patterns
+ - **Python**: pytest fixtures and parameterization
+ - **Java**: JUnit5 annotations and assertions
+ - **C#**: NUnit/xUnit attributes and theory data
+ - **Go**: Table-driven tests and subtests
+ - **Ruby**: RSpec expectations and contexts
+
+7. **Test Quality Checklist**
+ ✓ Tests are readable and self-documenting
+ ✓ Failure messages clearly indicate what went wrong
+ ✓ Tests follow DRY principle with appropriate abstractions
+ ✓ Coverage includes positive, negative, and edge cases
+ ✓ Tests can serve as living documentation
+ ✓ No implementation details leaked into tests
+ ✓ Tests use meaningful test data, not 'foo' and 'bar'
+
+8. **Common Anti-Patterns to Avoid**
+ - Writing tests that pass immediately
+ - Testing implementation instead of behavior
+ - Overly complex test setup
+ - Brittle tests tied to specific implementations
+ - Tests with multiple responsibilities
+ - Ignored or commented-out tests
+ - Tests without clear assertions
+
+Output should include:
+- Complete test file(s) with all necessary imports
+- Clear documentation of what each test validates
+- Verification commands to run tests and see failures
+- Metrics: number of tests, coverage areas, test categories
+- Next steps for moving to green phase"
+
+## Validation Steps
+
+After test generation:
+1. Run tests to confirm they fail
+2. Verify failure messages are helpful
+3. Check test independence and isolation
+4. Ensure comprehensive coverage
+5. Document any assumptions made
+
+## Recovery Process
+
+If tests don't fail properly:
+- Debug import/syntax issues first
+- Ensure test framework is properly configured
+- Verify assertions are actually checking behavior
+- Add more specific assertions if needed
+- Consider missing test categories
+
+## Integration Points
+
+- Links to tdd-green.md for implementation phase
+- Coordinates with tdd-refactor.md for improvement phase
+- Integrates with CI/CD for automated verification
+- Connects to test coverage reporting tools
+
+## Best Practices
+
+- Start with the simplest failing test
+- One behavior change at a time
+- Tests should tell a story of the feature
+- Prefer many small tests over few large ones
+- Use test naming as documentation
+- Keep test code as clean as production code
