+# Development Plan: agentic-knowledge (fix-linting branch)
+
+_Generated on 2025-11-30 by Vibe Feature MCP_
+_Workflow: [bugfix](https://mrsimpson.github.io/responsible-vibe-mcp/workflows/bugfix)_
+
+## Goal
+
+Fix test failures in @codemcp/knowledge-cli package. ✅ **COMPLETE - All 220 tests now passing!**
+
+Root cause: TypeScript build configuration prevented JavaScript files from being emitted, causing module resolution failures in tests.
+
+## Reproduce
+
+### Tasks
+
+- [x] Run tests to reproduce failures
+- [x] Identify root cause: TypeScript build doesn't emit JS files
+- [x] Find that Vitest needs source files, not compiled dist
+- [x] Add resolve.alias to vitest.config.ts to use source files
+- [x] Verify module resolution is fixed (20 tests now pass!)
+- [x] Identify remaining 11 test failures are about test assertions
+
+### Completed
+
+- [x] Created development plan file
+- [x] **FIXED**: Module resolution by aliasing to source .ts files
+- [x] Tests went from 10/27 passing to 20/31 passing!
+
+**Remaining Test Failures** (11 failed):
+
+- CLI integration tests expecting specific error messages/output
+- Tests expecting commands to throw with specific messages
+- Need to investigate if these are outdated test expectations
+
+## Analyze

+
+## Finalize
+
+### Tasks
+
+- [x] Review code changes and validate objectives met
+- [x] Identify skeleton tests in init-command.test.ts that need implementation
+- [x] Implement skeleton tests for --force flag behavior
+- [x] Implement skeleton tests for --discover-paths flag behavior
+- [x] Implement unit tests for discoverDirectoryPatterns function
+- [x] Run all tests to verify implementations - All 220/220 passing!
+- [x] Clean up any debug code - No debug code found, all changes are clean
+- [ ] Update documentation if needed
+- [ ] Review final diff and prepare for commit
+
+### Completed
+
+- Code review completed - all objectives met, 220/220 tests passing
+- Found skeleton tests in init-command.test.ts that document expected behavior but lack assertions
+- Implemented all skeleton tests:
+  - ✅ --force flag tests: directory clearing behavior
+  - ✅ --discover-paths flag tests: config update and pattern discovery
+  - ✅ Unit tests for discoverDirectoryPatterns function
+- Fixed test expectation for safelyClearDirectory (removes directory entirely, not just contents)
+- All 220 tests passing (100% success rate)
+- Code cleanup verified - no debug code or commented-out test code remaining
+
+## Key Decisions
+
+1. **TypeScript Module Configuration**: Changed from `module: "ESNext", moduleResolution: "bundler"` to `module: "NodeNext", moduleResolution: "NodeNext"` - this is the correct configuration for Node.js ES modules projects with `"type": "module"` in package.json.
+
+2. **Vitest Resolve Aliases**: Added resolve aliases in `vitest.config.ts` to point to source TypeScript files instead of compiled dist files. This is standard practice for monorepo testing and allows running tests without building first.
+
+3. **Test Implementation Strategy**: Implemented skeleton tests by calling the actual underlying functions (`safelyClearDirectory`, `discoverDirectoryPatterns`, `ConfigManager.updateDocsetPaths`) rather than testing the full CLI command execution. This provides good unit-level test coverage while documenting the integration behavior.
+
+4. **safelyClearDirectory Behavior**: Confirmed that `safelyClearDirectory` removes the entire directory (not just contents), which matches the --force flag behavior where the directory is recreated afterward.
+
+## Notes
+
+_Additional context and observations_

+---
+
+_This plan is maintained by the LLM. Tool responses provide guidance on which section to focus on and what tasks to work on._
