Product Development Expert

Comprehensive product development guidance for iOS/macOS apps. This skill orchestrates the entire product lifecycle from idea validation to App Store release.

When This Skill Activates

Use this skill when the user:

• Has an app idea and wants to validate it
• Needs market research or competitive analysis
• Wants to generate product specifications
• Needs architecture or UX design documents
• Is preparing for App Store submission
• Wants to plan beta testing or TestFlight strategy
• Needs localization strategy or market expansion planning
• Wants end-to-end product planning

Available Modules

WORKFLOW.md Product development workflow guide.

How to Use

1. Identify where user is in product lifecycle
2. Read relevant module SKILL.md for detailed process
3. Generate requested specifications
4. Save outputs to appropriate files

Example Workflows

User doesn't have an idea yet:

1. Use idea-generator/ to brainstorm and rank ideas
2. Pick top idea from shortlist
3. Run product-agent/ to validate the idea
4. Continue with market research and specs

User has new app idea:

1. Use product-agent/ for initial validation
2. Run market-research/ for market sizing
3. Run competitive-analysis/ for competitor insights
4. Generate PRD with prd-generator/

User wants full spec package:

1. Use implementation-spec/ orchestrator
2. It coordinates all spec generators
3. Produces complete documentation set
