# PRD: Complete CLI Interface Removal **GitHub Issue**: [#33](https://github.com/vfarcic/dot-ai/issues/33) **Status**: Complete **Priority**: Medium **Start Date**: 2025-07-23 **Target Completion**: 2025-08-13 ✅ ## Overview Complete the removal of CLI interface functionality that was previously started but left incomplete. This involves removing all CLI-related source code, tests, build configurations, and documentation while preserving the MCP server functionality. ## Problem Statement A previous session attempted to remove the CLI interface but left significant CLI-related code in the codebase: - **Core CLI files still exist**: `src/cli.ts`, `src/interfaces/cli.ts`, `bin/dot-ai.ts` - **Package.json still defines CLI**: Binary entries, CLI scripts, build configurations - **Full CLI test suite remains**: Comprehensive test coverage for removed functionality - **Documentation still references CLI**: Commands that no longer should exist - **Build system still compiles CLI**: Creates working CLI binaries This incomplete removal creates confusion about the project's interface strategy and maintains unnecessary code complexity. ## Success Criteria ### Primary Goals - [x] **All CLI source code removed**: No CLI-related files in `src/` directory - [x] **Package.json updated**: No CLI binary entries, scripts, or build references - [x] **Clean MCP-only interface**: Only MCP server functionality remains - [x] **Documentation updated**: No references to non-existent CLI commands - [x] **Tests updated**: No CLI test files, clean test suite execution - [x] **Build system cleaned**: No CLI compilation or binary generation ### Quality Gates - [x] **All tests pass**: `npm test` succeeds after all removals - [x] **MCP functionality intact**: MCP server and prompts work correctly - [x] **No broken references**: No imports or exports to removed CLI code - [x] **Documentation accuracy**: All documented commands and workflows are valid ## Functional Requirements ### CLI Code Removal - [x] **Remove core CLI files**: - [x] Delete `src/cli.ts` - [x] Delete `src/interfaces/cli.ts` - [x] Delete `bin/dot-ai.ts` - [x] Remove CLI export from `src/index.ts` - [x] **Remove CLI test infrastructure**: - [x] Delete `tests/interfaces/cli.test.ts` - [x] Update any other test files that reference CLI components - [x] Verify test suite runs cleanly ### Package.json Updates - [x] **Remove CLI binary entries**: - [x] Remove `"dot-ai": "./dist/cli.js"` from bin section - [x] Keep only `"dot-ai-mcp": "./dist/mcp/server.js"` - [x] **Remove CLI scripts**: - [x] Remove `"build:cli"` script - [x] Remove `"start:cli"` script - [x] Update `"postbuild"` to only handle MCP server permissions ### Documentation Updates - [x] **Update CLAUDE.md**: - [x] Remove references to `dot-ai discover`, `dot-ai explain`, `dot-ai fingerprint` - [x] Update "Key Commands" section to focus on MCP and npm commands - [x] Update project description to reflect MCP-only interface - [x] **Update project documentation**: - [x] Review all files in `docs/` directory for CLI references - [x] Update or remove CLI-focused documentation files - [x] Ensure setup guides focus on MCP server configuration - [x] **Update README.md**: - [x] Remove CLI installation and usage instructions - [x] Focus on MCP server setup and integration - [x] Update feature descriptions to reflect current architecture ## Implementation Approach ### Phase 1: Code Removal (Safe Cleanup) 1. **Remove CLI source files** - Delete main CLI implementation files 2. **Update exports** - Remove CLI exports from index files 3. **Remove CLI tests** - Delete CLI-specific test files 4. **Verify compilation** - Ensure project builds without CLI code ### Phase 2: Package Configuration (Interface Changes) 1. **Update package.json** - Remove CLI binary and script entries 2. **Update build scripts** - Remove CLI-specific build configurations 3. **Test packaging** - Verify npm package works correctly 4. **Verify MCP functionality** - Ensure MCP server still works ### Phase 3: Documentation Cleanup (User-Facing Updates) 1. **Audit all documentation** - Find every CLI reference across all files 2. **Update core documentation** - CLAUDE.md, README.md, setup guides 3. **Remove/update CLI-specific docs** - Handle docs that are CLI-only 4. **Verify documentation accuracy** - Test that all documented workflows work ## Dependencies ### Internal Dependencies - **MCP server functionality must remain intact** - This is the primary interface going forward - **Shared prompts functionality preserved** - CLI removal should not affect prompt library - **Core discovery and schema functionality preserved** - Business logic should be unaffected ### External Dependencies - **No external blockers identified** - This is internal code cleanup ## Risk Assessment ### Technical Risks - **🟡 Medium: Missed CLI references** - May miss some CLI imports or references in complex codebase - *Mitigation*: Comprehensive search for CLI-related patterns before removal - *Detection*: Build errors will catch missing imports - **🟡 Medium: Accidental MCP functionality removal** - Could accidentally remove shared code - *Mitigation*: Careful analysis of what CLI and MCP share before deletion - *Testing*: Verify MCP functionality after each removal step - **🟢 Low: Test suite breakage** - Some tests might fail after CLI removal - *Mitigation*: Update tests incrementally and run test suite frequently - *Recovery*: Easy to fix broken test imports and references ### Business Risks - **🟢 Low: User impact** - CLI removal should not affect current MCP users - **🟢 Low: Feature regression** - Core functionality delivered via MCP should be unaffected ## Success Metrics ### Technical Metrics - **Zero CLI-related files**: No files with CLI in name or primary purpose - **Clean package.json**: Only MCP-related scripts and binaries - **100% test pass rate**: All remaining tests execute successfully - **No build warnings**: Clean compilation without CLI references ### Documentation Metrics - **Zero broken CLI references**: No documentation mentions non-existent CLI commands - **Complete MCP focus**: All setup and usage docs focus on MCP integration - **Accurate workflows**: All documented workflows can be successfully executed ## Content Location Map This PRD manages code removal rather than documentation creation, so content changes are primarily deletions and updates to existing files: ### Files to Delete - `src/cli.ts` - Main CLI entry point - `src/interfaces/cli.ts` - CLI interface implementation - `bin/dot-ai.ts` - CLI binary entry point - `tests/interfaces/cli.test.ts` - CLI test suite ### Files to Update - `package.json` - Remove CLI binary and scripts - `src/index.ts` - Remove CLI exports - `CLAUDE.md` - Remove CLI command references, update project description - `README.md` - Remove CLI installation/usage, focus on MCP - Various `docs/*.md` files - Remove/update CLI references ### Files to Verify - All TypeScript files for CLI imports - All test files for CLI references - All documentation files for CLI command examples ## Open Questions - [ ] **Build system impact**: Are there any CI/CD or deployment scripts that reference CLI binaries? - [ ] **Documentation scope**: Should we create a "migration from CLI to MCP" guide for any existing users? - [ ] **Testing completeness**: Do we need additional tests to verify MCP functionality is unaffected? ## Decision Log ### 2025-07-23: Scope Decision **Decision**: Complete CLI removal with clean deletion approach **Rationale**: User confirmed no need for backward compatibility or migration path **Impact**: Simplifies implementation - no need for deprecation warnings or migration guides ## Work Log ### 2025-07-23: PRD Creation **Duration**: 30 minutes **Tasks Completed**: - [x] Created GitHub issue #33 - [x] Created comprehensive PRD document - [x] Identified all CLI-related files requiring removal - [x] Planned implementation phases focusing on safe, incremental removal **Next Session Priority**: Begin Phase 1 (Code Removal) starting with CLI source file deletion ### 2025-08-14: CLI Removal Implementation **Duration**: ~2 hours (based on commit timestamps) **Commits**: 2 commits (4f3a57c, e92a4db) **Primary Focus**: Complete CLI interface removal and package cleanup **Completed PRD Items**: -
