Example Workflows
User doesn't have an idea yet:
- Use
idea-generator/ to brainstorm and rank ideas
- Pick top idea from shortlist
- Run
product-agent/ to validate the idea
- Continue with market research and specs
User has new app idea:
- Use
product-agent/ for initial validation
- Run
market-research/ for market sizing
- Run
competitive-analysis/ for competitor insights
- Generate PRD with
prd-generator/
User wants full spec package:
- Use
implementation-spec/ orchestrator
- It coordinates all spec generators
- Produces complete documentation set
