Core Patterns

Pattern 1: Skill Creation (≤500 lines)

## Advanced Implementation (10+ minutes)

Pattern 2: Sub-agent Delegation

# Sequential delegation
result1 = Task(subagent_type="workflow-spec", prompt="Analyze")
result2 = Task(subagent_type="code-backend", prompt="Implement", context=result1)

# Parallel delegation
results = await Promise.all([
 Task(subagent_type="code-backend", prompt="Backend"),
 Task(subagent_type="code-frontend", prompt="Frontend")
])

Pattern 3: Custom Command with Hooks

{
 "hooks": {
 "PreToolUse": [{
 "matcher": "Write",
 "hooks": [{"type": "command", "command": "validate-write"}]
 }]
 }
}

Quick Access Patterns

Core Skills: Skill("moai-foundation-claude") - This comprehensive authoring kit Agent Creation: Task(subagent_type="agent-factory") - Create standardized sub-agents Skill Creation: Task(subagent_type="skill-factory") - Create compliant skills Quality Gates: Task(subagent_type="quality-gate") - TRUST 5 validation Documentation: Task(subagent_type="docs-manager") - Generate technical docs

Key Specialized Skills:

• moai-lang-python - Python 3.13+ with FastAPI, async patterns
• moai-lang-typescript - TypeScript 5.9+ with React 19, Next.js 16
• moai-domain-backend - Modern backend architecture patterns
• moai-domain-frontend - React 19, Next.js 15, Vue 3.5 frameworks
• moai-quality-security - OWASP Top 10, threat modeling
• moai-essentials-debug - AI-powered debugging with Context7

Essential Sub-agents:

• spec-builder - EARS format specification generation
• tdd-implementer - RED-GREEN-REFACTOR TDD execution
• security-expert - Security analysis and validation
• backend-expert - Backend architecture and API development
• frontend-expert - Frontend UI implementation
• performance-engineer - Performance optimization and analysis

Essential Implementation Patterns

Command→Agent→Skill Orchestration

Sequential Workflow:

# Phase 1: Analysis → spec-builder → analysis
analysis = Task(subagent_type="spec-builder", prompt="Analyze: $ARGUMENTS")
# Phase 2: Implementation → tdd-implementer → code + tests
implementation = Task(subagent_type="tdd-implementer", prompt="Implement: $analysis.spec_id")
# Phase 3: Validation → quality-gate → approval
validation = Task(subagent_type="quality-gate", prompt="Validate: $implementation")

Parallel Development:

# Execute independent tasks simultaneously
results = await Promise.all([
 Task(subagent_type="backend-expert", prompt="Backend: $1"),
 Task(subagent_type="frontend-expert", prompt="Frontend: $1"),
 Task(subagent_type="docs-manager", prompt="Docs: $1")
])
# Integrate all results
Task(subagent_type="quality-gate", prompt="Integrate", context={"results": results})

Token Session Management

Independent 200K Sessions: Each Task() creates a new 200K token context

Task(subagent_type="backend-expert", prompt="Complex task") # 200K session
Task(subagent_type="frontend-expert", prompt="UI task") # New 200K session

File Reference Patterns

Parameter Handling:

• Positional: $1, $2, $3
• All arguments: $ARGUMENTS
• File references: @config.yaml, @path/to/file.md

Hook Integration

Pre/Post Tool Execution (see Hooks Guide):

{
 "hooks": {
 "PreToolUse": [{"matcher": "Bash", "hooks": [{"type": "command", "command": "validate-command"}]}],
 "PostToolUse": [{"matcher": "Write", "hooks": [{"type": "command", "command": "backup-file"}]}]
 }
}
