[ ] Existing MCP server infrastructure (src/mcp/server.ts) - ✅ Available - [ ] MCP server registration and capability system - ✅ Available - [ ] TypeScript build and development environment - ✅ Available ### Current Blockers - [ ] None currently identified - all dependencies are satisfied ## Risk Management ### Identified Risks - [ ] **Risk**: Prompt naming conflicts with existing commands | **Mitigation**: Use consistent `mcp__dot-ai__` prefix, test naming | **Owner**: Developer - [ ] **Risk**: Large prompt content impacting performance | **Mitigation**: Set reasonable prompt size limits, implement caching | **Owner**: Developer - [ ] **Risk**: Team adoption resistance due to unfamiliarity | **Mitigation**: Clear documentation, gradual rollout, training | **Owner**: Team Lead - [ ] **Risk**: Prompt quality inconsistency | **Mitigation**: Establish review process, prompt templates, guidelines | **Owner**: Curator ### Mitigation Actions - [ ] Create prompt contribution guidelines and review process - [ ] Implement prompt size and format validation - [ ] Develop comprehensive documentation and examples - [ ] Plan gradual team introduction with high-value prompts first ## Decision Log ### Open Questions - [ ] What prompt categories should we implement initially? (code-review, documentation, architecture, debugging) - [ ] Should we support prompt parameters/arguments in v1 or keep strictly static? - [ ] What's the ideal prompt storage format - separate files vs embedded data? - [ ] How should we handle prompt versioning and updates? - [ ] Do MCP prompts work similarly in Cursor, VS Code, and other coding agents as they do in Claude Code? - [ ] Are there client-specific differences in prompt naming, discovery, or execution that we need to accommodate? ### Resolved Decisions - [x] Use standard MCP Prompts specification - **Decided**: 2025-01-22 **Rationale**: Standardized approach, native Claude Code integration - [x] Target native slash command experience - **Decided**: 2025-01-22 **Rationale**: Research confirmed MCP prompts become `/mcp__servername__prompt` commands - [x] Static prompts only for v1 - **Decided**: 2025-01-22 **Rationale**: Simpler implementation, clear scope, meets core need - [x] Build on existing dot-ai MCP server - **Decided**: 2025-01-22 **Rationale**: Leverage existing infrastructure, single server deployment ## Scope Management ### In Scope (Current Version) - [x] Static prompts only (no dynamic arguments) - [x] New standalone prompts (separate from existing workflow prompts) - [x] Standard MCP Prompts implementation (`prompts/list`, `prompts/get`) - [x] Native slash command integration (`/mcp__dot-ai__*`) - [x] Basic prompt organization and metadata - [x] File-based prompt storage - [x] Integration with existing dot-ai MCP server ### Out of Scope (Future Versions) - [~] Dynamic prompt arguments/parameters - [~] Integration with existing workflow prompts (recommend, generate, etc.) - [~] Web-based prompt management UI - [~] Prompt analytics and usage tracking - [~] User-submitted prompt contributions - [~] Prompt versioning and history ### Deferred Items - [~] Advanced prompt search and filtering - **Reason**: Complex for v1, basic list sufficient initially **Target**: Phase 3 - [~] Prompt contribution workflow - **Reason**: Need to establish core library first **Target**: Future version - [~] Usage analytics - **Reason**: Focus on core functionality first **Target**: Phase 3 - [~] Prompt templates with parameters - **Reason**: Static prompts meet immediate need **Target**: v2.0 ## Testing & Validation ### Test Coverage Requirements -

[MCP Prompts Specification](https://modelcontextprotocol.io/docs/concepts/prompts) - [Claude Code MCP Integration Documentation](https://docs.anthropic.com/en/docs/claude-code/mcp) - [Existing dot-ai MCP Server Implementation](./src/mcp/server.ts) ### Research Findings - MCP prompts automatically become native slash commands in Claude Code - Format: `/mcp__servername__promptname` - Users can discover prompts by typing `/` in Claude Code - Prompts work identically to `.claude/commands/` but with centralized management - No client-side setup required - prompts available immediately upon MCP server connection ### Example Prompt Structure ```json { "id": "code-review-security", "name": "Security-Focused Code Review", "description": "Comprehensive security analysis prompt for code review", "category": "code-review", "content": "Please review this code with focus on security vulnerabilities..." } ``` ### Implementation References -
