Product Development

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

Read relevant module files based on the user's needs:

Phase 0: Idea Discovery

idea-generator/

Brainstorm and rank app ideas via 5 lenses.

• Developer profile elicitation (skills, interests, constraints)
• Five brainstorming lenses (skills, problem-first, technology-first, market gap, trend-based)
• Feasibility filtering and scoring
• Ranked shortlist of 3-5 ideas with next_step commands

app-namer/

Turn a chosen idea into validated, App-Store-ready name candidates.

• Branded vs. descriptive vs. hybrid archetypes, paired with a subtitle
• App Store display rules (30-char limit, Home-Screen truncation, name/subtitle interplay)
• Validation gauntlet: App Store Connect name, trademark knockout, domain/.app, social handle, linguistic safety
• Ranked shortlist with scores and a "reserve now" action; feeds app-store/keyword-optimizer

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
• Run app-namer/ to name it and reserve the App Store name
• 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
