Start Project Skill - Feature Initialization

Orchestrate the start of new feature development.

Workflow

Phase 1: Research (Claude Subagents)

1. Codebase Exploration

   Task(subagent_type="Explore", prompt="""
   Explore codebase for:
   - Related existing implementations
   - Patterns used in similar features
   - Dependencies and interfaces
   
   Return: File paths and key patterns found
   """)
   

2. External Research (if needed)

   • WebSearch for library documentation
   • WebFetch for specific API references

Phase 2: Requirements Gathering

1. Ask user clarifying questions
2. Document requirements
3. Identify constraints

Phase 3: Design Consultation (Codex)

Task(subagent_type="general-purpose", prompt="""
Consult Codex for design:

codex exec --model o3 --sandbox read-only --full-auto "
Design approach for: {feature}

Research findings:
{research summary}

Requirements:
{requirements}

Recommend:
1. Architecture approach
2. Key design decisions
3. Potential issues
4. Implementation order
"

Return concise design summary.
""")

Phase 4: Task Creation

1. Create task list based on plan
2. Set task dependencies
3. Present for user approval
