A collection of 4 specialized sub-agents designed for hybrid product/engineers who build products end-to-end - from concept validation to stakeholder presentation.
Product builders who code - the hybrid product/engineers who:
- 🚀 Build products from idea to launch (not just implement tickets)
- 🧪 Need to validate concepts before heavy development investment
- 💼 Present progress to stakeholders, investors, and users
- 📋 Plan features and break down complex product requirements
- 🎨 Create prototypes for user testing and concept validation
- 📖 Document products for non-technical users and team members
Not for pure developers who focus solely on implementation within existing codebases.
- Copy the agent files to your
.claude/agents/directory (project-level) or~/.claude/agents/(user-level) - Use
/agentscommand to manage and configure - Agents will activate automatically based on your requests
Transforms product ideas into structured development plans
Perfect for breaking down that ambitious feature idea into actionable development work.
- Creates comprehensive PRDs from rough product concepts
- Generates structured task breakdowns with clear implementation order
- Provides architectural guidance and identifies technical dependencies
- Researches industry patterns and analyzes existing product architecture
Product Builder Scenario: "I want to add AI-powered expense categorization to my fintech app" → Complete PRD + 47 structured development tasks with technical guidance
Builds testable product prototypes for validation
Essential for testing product concepts before committing to full development.
- Creates sophisticated interactive prototypes that feel like real products
- Uses professional iconography (Ionicons) and modern web technologies
- Responsive design with smooth animations and micro-interactions
- Perfect for user testing, stakeholder demos, and investor presentations
Product Builder Scenario: "I need to test if users understand my onboarding flow" → Working interactive prototype ready for user testing
Creates user-facing product documentation
Bridges the gap between technical implementation and user understanding.
- Generates complete user guides, API documentation, and feature explanations
- Progressive complexity that works for both technical and non-technical audiences
- Working examples and practical use cases throughout
- Professional formatting ready for customer-facing documentation
Product Builder Scenario: "I need to document our API for third-party developers" → Complete API docs with examples and integration guides
Builds data-driven stakeholder presentations
Turn your product metrics and progress into compelling stakeholder communications.
- Creates professional HTML presentations with interactive data visualizations
- Processes uploaded data (CSV, Excel) into Chart.js visualizations
- Self-contained presentations ready for board meetings or investor updates
- Mobile-responsive with speaker notes and professional styling
Product Builder Scenario: "Present our user growth metrics to investors" → Professional presentation with interactive charts and executive summary

→ Get results presentation for stakeholders
| Product Challenge | Agent Solution | Typical Output |
|---|---|---|
| "This feature idea is too complex to start coding" | ai-dev-task-master |
Structured development plan with clear phases |
| "I need to test this concept with users first" | prototype-builder |
Interactive prototype for user testing |
| "Users don't understand how to use this feature" | docs-expert |
Clear user guides and tutorials |
| "I need to show progress to investors/stakeholders" | presentation-architect |
Professional presentation with metrics |
Building an MVP and wearing all hats - PM, designer, engineer, marketer
- Uses all 4 agents throughout the product development cycle
- Relies heavily on prototyping for validation before building
- Needs professional presentations for fundraising
Leading product development in a 2-5 person startup
- Uses task-master for feature planning and team coordination
- Creates prototypes for stakeholder alignment
- Documents features for non-technical team members
Technical team member who bridges product and engineering
- Breaks down product requirements into technical tasks
- Builds prototypes for design and user research collaboration
- Creates technical documentation for product features
Building products independently for specific markets
- Heavy prototype usage for market validation
- Documentation for users and potential customers
- Presentations for partnerships and business development
cp agents/*.md .claude/agents/cp agents/*.md ~/.claude/agents/claude /agents- Start with validation: Use
prototype-builderbefore heavy development investment - Plan before building: Use
ai-dev-task-masterto avoid scope creep and technical debt - Document as you go: Use
docs-expertto create user-facing documentation alongside development - Communicate progress: Use
presentation-architectto keep stakeholders aligned and engaged
Contributions should focus on real product building workflows and challenges. Test with actual product development scenarios, not just technical implementation tasks.
