Quick Reference

When to Use Each Subagent

Task TypeRecommended SubagentExample Use Case
Building UI componentsFrontend UI Expert"Create a responsive navigation bar"
Code quality reviewProduction Validator"Review this code for production readiness"
Writing documentationCode Documentor"Document this authentication module"
Complex researchGeneral Purpose"Find all API endpoints in this codebase"
Multi-step automationGeneral Purpose"Set up CI/CD pipeline with testing"

Subagent Invocation Patterns

# Using Task tool to invoke subagents
/task description="Build user profile component" subagent_type="frontend-ui-expert"
/task description="Review code quality" subagent_type="production-validator"
/task description="Create API docs" subagent_type="code-documentor"
/task description="Research database schema" subagent_type="general-purpose"

Best Practices

Choosing the Right Subagent

  1. Match Task to Expertise: Choose the subagent whose specialty aligns with your task
  2. Consider Tool Requirements: Some subagents have limited tool access by design
  3. Think About Context: Specialized agents maintain better focused context
  4. Use General Purpose for Complex Tasks: When tasks span multiple domains, use the general-purpose agent

Effective Subagent Usage

  1. Be Specific: Provide clear, detailed task descriptions
  2. Set Clear Expectations: Specify what you want the subagent to deliver
  3. Provide Context: Include relevant background information
  4. Chain Subagents: Use multiple subagents in sequence for complex workflows

Common Patterns

# Frontend Development Workflow
1. Frontend UI Expert: Build component
2. Production Validator: Review for production
3. Code Documentor: Create component documentation

# Code Review Workflow  
1. Production Validator: Initial quality check
2. General Purpose: Complex analysis if needed
3. Code Documentor: Update documentation

# Research and Implementation
1. General Purpose: Research and planning
2. Specialized Agent: Implementation
3. Production Validator: Final review

Integration Workflows

Multi-Agent Workflows

Claude Code allows you to chain subagents together for complex workflows:

  1. Sequential Processing: Use agents one after another
  2. Parallel Processing: Run multiple agents concurrently
  3. Conditional Logic: Choose agents based on task requirements

Example Workflows

Complete Feature Development

1. General Purpose: Research requirements and plan architecture
2. Frontend UI Expert: Build user interface components  
3. Production Validator: Review code quality and security
4. Code Documentor: Create comprehensive documentation

Code Quality Pipeline

1. Production Validator: Automated quality checks
2. General Purpose: Complex issue analysis (if needed)
3. Frontend UI Expert: UI-specific fixes (if applicable)
4. Code Documentor: Update documentation

Getting Started

  1. Identify Your Task Type: Determine which subagent is most appropriate
  2. Use the Task Tool: Invoke the subagent using Claude Code's Task tool
  3. Provide Clear Instructions: Be specific about what you want accomplished
  4. Review Results: Each subagent will provide a focused response
  5. Chain as Needed: Use multiple subagents for complex workflows

Advanced Usage

Custom Subagent Patterns

You can create sophisticated workflows by combining subagents with Claude Code's other features:

  • Session Management: Maintain context across subagent invocations
  • Tool Permissions: Configure specific tool access for security
  • Output Formatting: Use structured output for automation
  • Error Handling: Implement fallback patterns between subagents

Performance Optimization

  • Use specialized subagents to reduce context switching
  • Leverage parallel subagent execution when possible
  • Cache common subagent results for repeated tasks
  • Monitor subagent performance with Claude Code's cost tracking
