### 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 ## Subagent Format
Each subagent follows this structure: Each subagent is defined as a Markdown file with frontmatter:
```markdown ```markdown
--- ---
name: subagent-name name: subagent-name
description: When this subagent should be invoked description: Activation criteria for this subagent
model: haiku # Optional - specify which model to use (haiku/sonnet/opus) model: haiku|sonnet|opus # Optional: Model selection
tools: tool1, tool2 # Optional - defaults to all tools tools: tool1, tool2 # Optional: Tool restrictions
--- ---
System prompt defining the subagent's role and capabilities System prompt defining the subagent's expertise and behavior
``` ```
### Model Configuration ### Model Selection Criteria
As of Claude Code v1.0.64, subagents can specify which Claude model they should use. This allows for cost-effective task delegation based on complexity: - **haiku**: Simple, deterministic tasks with minimal reasoning
- **sonnet**: Standard development and engineering tasks
- **Low Complexity (Haiku)**: Simple tasks like basic data analysis, documentation generation, and standard responses - **opus**: Complex analysis, architecture, and critical operations
- **Medium Complexity (Sonnet)**: Development tasks, code review, testing, and standard engineering work
- **High Complexity (Opus)**: Critical tasks like security auditing, architecture review, incident response, and AI/ML engineering
Available models (using simplified naming as of Claude Code v1.0.64):
- `haiku` - Fast and cost-effective for simple tasks
- `sonnet` - Balanced performance for most development work
- `opus` - Most capable for complex analysis and critical tasks
If no model is specified, the subagent will use the system's default model.
## Agent Orchestration Patterns ## Agent Orchestration Patterns
Claude Code automatically coordinates agents using these common patterns: ### Sequential Processing
Agents execute in sequence, passing context forward:
### Sequential Workflows
``` ```
User Request → Agent A → Agent B → Agent C → Result
Example: "Build a new API feature"
backend-architect → frontend-developer → test-automator → security-auditor backend-architect → frontend-developer → test-automator → security-auditor
``` ```
### Parallel Execution ### Parallel Execution
Multiple agents work simultaneously on different aspects:
``` ```
User Request → Agent A + Agent B (simultaneously) → Merge Results performance-engineer + database-optimizer → Merged analysis
Example: "Optimize application performance"
performance-engineer + database-optimizer → Combined recommendations
``` ```
### Conditional Branching ### Conditional Routing
Dynamic agent selection based on analysis:
``` ```
User Request → Analysis → Route to appropriate specialist debugger → [backend-architect | frontend-developer | devops-troubleshooter]
Example: "Fix this bug"
debugger (analyzes) → Routes to: backend-architect OR frontend-developer OR devops-troubleshooter
``` ```
### Review & Validation ### Validation Pipeline
Primary work followed by specialized review:
``` ```
Primary Agent → Review Agent → Final Result
Example: "Implement payment processing"
payment-integration → security-auditor → Validated implementation payment-integration → security-auditor → Validated implementation
``` ```

## Troubleshooting ## Troubleshooting
### Common Issues ### Agent Not Activating
- Ensure request clearly indicates the domain
- Be specific about task type and requirements
- Use explicit invocation if automatic selection fails
**Agent not being invoked automatically:** ### Unexpected Agent Selection
- Ensure your request clearly indicates the domain (e.g., "performance issue" → performance-engineer) - Provide more context about tech stack
- Be specific about the task type (e.g., "review code" → code-reviewer) - Include specific requirements in request
- Use direct agent naming for precise control
**Unexpected agent selection:** ### Conflicting Recommendations
- Provide more context about your tech stack and requirements - Normal behavior - specialists have different priorities
- Use explicit invocation if you need a specific agent - Request reconciliation between specific agents
- Consider trade-offs based on project requirements
**Multiple agents producing conflicting advice:** ### Missing Context
- This is normal - different specialists may have different priorities - Include background information in requests
- Ask for clarification: "Reconcile the recommendations from security-auditor and performance-engineer" - Reference previous work or patterns
- Provide project-specific constraints
**Agent seems to lack context:**
- Provide background information in your request
- Reference previous conversations or established patterns
### Getting Help
If agents aren't working as expected:
1. Check agent descriptions in their individual files
2. Try more specific language in your requests
3. Use explicit invocation to test specific agents
4. Provide more context about your project and goals

```
### When Team Resists TDD
```bash

Prompt: "Create gradual TDD adoption plan for team with training materials"
```
## Advanced TDD Techniques
### Approval Testing
```bash
Use Task tool with subagent_type="test-automator"
