# PROJECT_BRIEF.md
## Basic Information
- **Project Name**: DevPlan MCP Server
- **Project Type**: api
- **Primary Goal**: MCP server that transforms project ideas into paint-by-numbers development plans executable by AI coding assistants
- **Target Users**: Claude Code users, AI-assisted developers, Development teams using AI coding tools
- **Timeline**: Ongoing development
- **Team Size**: 1+
## Functional Requirements
### Key Features (MVP - Implemented)
- Generate Haiku-executable development plans from project briefs
- Built-in plan validation and verification
- Lessons learned system for continuous improvement
- GitHub issue to remediation task conversion
- Executor and Verifier agent generation
- Visual workflow export (Mermaid, ReactFlow)
- Claude Code Task tools integration
### Nice-to-Have Features (v2)
- Multi-model agent support (Cursor, Aider, Cline, Windsurf, Generic)
- Template customization and extension system
- Community adapter contributions
- Model-specific verbosity tuning
## Technical Constraints
### Must Use
- TypeScript
- Cloudflare Workers (Wrangler)
- SSE transport for MCP
- Vitest for testing
### Cannot Use
- Server-side databases (use KV for persistence)
- Long-running processes (serverless constraints)
## Other Constraints
- Plans must be Haiku-executable (mechanical implementation without interpretation)
- Backward compatibility required for existing users
- Must work with Claude Code's native MCP integration
## Success Criteria
- All MVP features implemented and working
- Code passes linting and type checking
- Test coverage >= 80%
- Documentation complete
- Plans successfully executed by Haiku model
