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`

Discovery & Validation

**product-agent/** AI-powered product discovery and validation.

• Idea validation and assessment
• MVP scoping
• Market opportunity analysis

**market-research/** Deep market analysis.

• Market sizing (TAM/SAM/SOM)
• Growth trends and maturity
• Entry barriers and distribution channels
• Revenue potential

**competitive-analysis/** Competitor deep dive.

• Feature comparison matrices
• Pricing analysis
• Strengths/weaknesses
• Differentiation opportunities

Specification Generation

**prd-generator/** Product Requirements Document.

• Features and user stories
• Acceptance criteria
• Success metrics

**architecture-spec/** Technical architecture.

• Architecture pattern selection
• Tech stack decisions
• Data models
• App structure

**ux-spec/** UI/UX specifications.

• Wireframes and user flows
• Design system definition
• Interaction patterns

**implementation-guide/** Development roadmap.

• Step-by-step instructions
• Pseudo-code examples
• Implementation priorities

**test-spec/** QA and testing strategy.

• Unit test coverage
• UI testing plan
• Accessibility testing
• Beta testing strategy

**release-spec/** App Store preparation.

• Submission guide
• Asset requirements
• Privacy compliance
• Marketing strategy

Pre-Launch

**beta-testing/** TestFlight beta program strategy and feedback collection.

• Internal vs. external testing cohort management
• Beta tester recruitment and incentive strategies
• Feedback collection methodology (in-app, surveys, interviews)
• Signal vs. noise framework for interpreting feedback
• Go/no-go launch decision framework

**localization-strategy/** Market prioritization and localization planning.

• Language tier recommendations by app category
• Minimum viable localization levels (metadata-only to full)
• Translation workflow with Xcode String Catalogs
• Cultural adaptation beyond translation
• Localized ASO strategy

Orchestration

**implementation-spec/** Master orchestrator.

• Generates complete specification package
• Coordinates all role-based agents
• End-to-end spec generation

**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. Run `app-namer/` to name it and reserve the App Store name 5. 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
