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
