Phase 1: Complete MCP server with filesystem backend\n2. Phase 2: Add Docker infrastructure for database management\n3. Phase 3: Fix graph backend integration with proper dependencies\n4. Phase 4: Add remote transport capabilities\n\n## Development Strategy\n- Focus on getting the MCP server working with filesystem backend first\n- Implement Docker commands for database management\n- Gradually enable graph backend features once dependencies are resolved\n- Add comprehensive testing throughout\n\n## Current Blockers\n- Graph backend requires significant refactoring for new FalkorDB API\n- Vector search needs additional ML dependencies\n- Type system needs cleanup for proper error handling\n\n## Files Modified\n- `package.json`: Added all necessary dependencies\n- `src/core/backend-manager.ts`: GraphBackend enabled but temporarily disabled\n- `src/core/types.ts`: Core type definitions created\n- `src/core/storage-interface.ts`: Cleaned up type imports\n- `kb/implementation/`: Documentation added",

This dependency comes from `@xenova/transformers` which is only used for vector embeddings in the graph backend.\n\n## Impact\n- Users getting installation errors when running `npm install -g kb-mcp`\n- Bun installations fail with native compilation errors\n- Users who only need filesystem backend are forced to install heavy ML dependencies\n\n## Current Workaround\n```bash\n# Install with ignored scripts\nnpm install -g kb-mcp --ignore-scripts\n\n# Or use the installation script\ncurl -sSL https://raw.githubusercontent.com/moikas-code/kb-mcp/master/scripts/install-global.sh | bash\n```\n\n## Proposed Solution\n1. Make `@xenova/transformers` an optional dependency\n2. Lazy-load it only when graph backend with vector search is used\n3. Provide clear error message if vector search is attempted without the dependency\n\n## Implementation Notes\n- The dependency is only imported in `src/graph/vector-memory.ts`\n- Could use dynamic import: `await import('@xenova/transformers')`\n- Add try-catch to provide helpful error message\n- Document that vector search requires additional installation step\n\n## Priority\nMedium - affects user experience but has workarounds",

      "content": "# KB Entries vs Markdown Files Issue\n\n## The Problem\nYou noticed JSON entries in `/kb/entries/` with empty content instead of markdown files.\n\n## Root Cause\nThere are **two different KB systems** at play:\n\n### 1. NPM-installed KB CLI (v1.2.1)\n- Creates JSON metadata in `/kb/entries/` directory\n- Stores entries like: `{id, title, content: '', tags, created_at, updated_at}`\n- The content is empty because it expects a different backend\n\n### 2. Our Project's KB System  \n- Uses direct markdown files in directories\n- Expects structure like: `/kb/active/ISSUE.md`, `/kb/docs/guide.md`\n- Integrated with BackendManager for filesystem/graph switching\n\n## What Happened\n1. You used `kb write \"kb/active/CLI_CONSOLIDATION.md\" \"content\"`\n2. The NPM CLI created `/kb/entries/mcv60mwm5e06078m9al.json` with empty content\n3. No actual markdown file was created in `/kb/active/`\n4. The `/kb/active/` directory doesn't even exist\n\n## Solution\nWe need to:\n1. Use our project's CLI (once fixed) instead of the NPM version\n2. Or manually create the proper directory structure\n3. Or update the NPM CLI to match our backend\n\n## Current Status\n- Our unified CLI has build issues with path aliases\n- The NPM CLI uses a different storage format\n- Need to decide which approach to standardize on",

Keep src/cli/index.ts as the main implementation\n2. Add BackendManager support to replace SecureKBManager\n3. Remove all alternate CLI versions\n4. Update build and packaging to use single CLI\n\n## Implementation Plan\n- [ ] Analyze feature differences between CLIs\n- [ ] Update main CLI to use BackendManager\n- [ ] Remove alternate CLI files\n- [ ] Update package.json and build scripts\n- [ ] Test unified implementation\n- [ ] Update documentation",
