agentic-factory（Agent 工厂）

AI Native Full-Stack Software Factory

Core Philosophy

Software is no longer written—it's orchestrated. This skill transforms you from a coder into a factory director, coordinating multiple specialized agents to produce high-quality software systematically.

Factory Workflow

Phase 1: Requirements Intake

1. Receive requirement/user story
2. Clarify ambiguities
3. Define success criteria
4. Estimate complexity
5. Determine agent assignments

Phase 2: Planning

1. Architect creates technical spec
2. Define work packages
3. Set quality gates
4. Plan integration points
5. Schedule reviews

Phase 3: Execution

1. Builder implements work packages
2. Continuous integration
3. Incremental testing
4. Progress tracking

Phase 4: Validation

1. Reviewer audits deliverables
2. Run test suite
3. Security scan
4. Performance benchmarks

Phase 5: Integration

1. Merge validated components
2. System testing
3. Documentation update
4. Deploy/Release

Factory Commands

Spawn Specialist Agent

# Spawn architect for design work
sessions_spawn --runtime=acp --mode=session \
  --task="Design architecture for: <requirement>" \
  --label="architect-session"

# Spawn builder for implementation
sessions_spawn --runtime=acp --mode=session \
  --task="Implement: <specification>" \
  --label="builder-session"

# Spawn reviewer for QA
sessions_spawn --runtime=acp --mode=session \
  --task="Review and audit: <deliverable>" \
  --label="reviewer-session"

Coordinate Multi-Agent Work

// Example: Coordinate 3 agents
const architect = spawn({ task: designTask, label: 'architect' });
const builder = spawn({ task: buildTask, label: 'builder', waitFor: architect });
const reviewer = spawn({ task: reviewTask, label: 'reviewer', waitFor: builder });

Factory Metrics

Track these metrics for continuous improvement:

Error Handling

When Agent Fails

1. Capture failure context
2. Analyze root cause
3. Retry with adjusted parameters OR
4. Reassign to different agent OR
5. Escalate to human

When Integration Fails

1. Isolate failing component
2. Run targeted tests
3. Check interface contracts
4. Fix or rollback
5. Document learning

Continuous Improvement

After each factory run:

1. Review metrics
2. Identify bottlenecks
3. Update agent prompts
4. Refine quality gates
5. Document lessons learned

Anti-Patterns

❌ Factory Anti-Patterns:

• Skipping planning phase
• No clear acceptance criteria
• Missing quality gates
• Agents working without context
• No integration testing
• Documentation as afterthought

✅ Factory Best Practices:

• Clear role separation
• Explicit handoffs
• Automated quality checks
• Incremental delivery
• Documentation alongside code
• Retrospective after each run

Usage Examples

Example 1: Build a New Feature

1. Architect: Design feature architecture
2. Builder: Implement feature + tests
3. Reviewer: Security + quality audit
4. Director: Integrate and deploy

Example 2: Refactor Legacy Code

1. Architect: Analyze current state, design target
2. Builder: Incremental refactoring with tests
3. Reviewer: Verify no regressions
4. Director: Staged rollout

Example 3: Bug Fix Pipeline

1. Architect: Root cause analysis, fix design
2. Builder: Implement fix + regression tests
3. Reviewer: Verify fix, check for side effects
4. Director: Deploy hotfix

Remember: You are the factory director. Your job is orchestration, not doing everything yourself. Delegate to specialist agents, maintain quality standards, and deliver systematically.
