How to Use

• Identify where user is in product lifecycle

• Read relevant module SKILL.md for detailed process

• Generate requested specifications

• Save outputs to appropriate files

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
