# Changelog
## [1.3.3] - 2026-01-18
### Fixed
- **Security**: Resolve `pnpm audit` advisories by updating `hono` to 4.11.4 and removing the vulnerable `diff` transitive dependency (replaced `ts-node` with `tsx` for `pnpm dev`).
### Changed
- **Docs**: Clarify private `internal-docs/` submodule setup, add `npx --yes` tip, document `CODEBASE_ROOT`, and list `get_indexing_status` tool.
- **Submodule**: Disable automatic updates for `internal-docs` (`update = none`).
### Removed
- **Dev**: Remove local-only `test-context.cjs` helper script.
## [1.3.2] - 2026-01-16
### Changed
- **Embeddings**: Batch embedding now uses a single Transformers.js pipeline call per batch for higher throughput.
- **Dependencies**: Bump `@modelcontextprotocol/sdk` to 1.25.2.
## [1.3.1] - 2026-01-05
### Fixed
- **Auto-Heal Semantic Search**: Detects LanceDB schema corruption (missing `vector` column), triggers re-indexing, and retries search instead of silently falling back to keyword-only results.
## [1.3.0] - 2026-01-01
### Added
- **Workspace Detection**: Monorepo support for Nx, Turborepo, Lerna, and pnpm workspaces
- New utility: `src/utils/workspace-detection.ts`
- Functions: `scanWorkspacePackageJsons()`, `detectWorkspaceType()`, `aggregateWorkspaceDependencies()`
- **Testing Infrastructure**: Vitest smoke tests for core utilities
- Tests for workspace detection, analyzer registry, and indexer metadata
- CI/CD workflow via GitHub Actions
- **Dependency Detection**: Added `@nx/` and `@nrwl/` prefix matching for build tools
### Fixed
- **detectMetadata() bug**: All registered analyzers now contribute to codebase metadata (previously only the first analyzer was called)
- Added `mergeMetadata()` helper with proper array deduplication and layer merging
### Changed
- Updated roadmap: v1.3 is now "Extensible Architecture Foundation"
### Acknowledgements
Thanks to [@aolin480](https://github.com/aolin480) for accelerating the workspace detection roadmap and identifying the detectMetadata() limitation in their fork.
## 1.2.2 (2025-12-31)
### Fixed
- **Critical Startup Crash**: Fixed immediate "Exit Code 1" silent crash on Windows by handling unhandled rejections during startup
- **MCPJam Compatibility**: Removed `logging` capability (which was unimplemented) to support strict MCP clients like MCPJam
- **Silent Failure**: Added global exception handlers to stderr to prevent silent failures in the future
## 1.2.1 (2025-12-31)
### Fixed
- **MCP Protocol Compatibility**: Fixed stderr output during MCP STDIO handshake for strict clients
- All startup `console.error` calls now guarded with `CODEBASE_CONTEXT_DEBUG` env var
- Zero stderr output during JSON-RPC handshake (required by Warp, OpenCode, MCPJam)
- Debug logs available via `CODEBASE_CONTEXT_DEBUG=1` environment variable
- Minimal implementation: 2 files changed, 46 insertions, 25 deletions
- Reported by [@aolin480](https://github.com/aolin480) in [#2](https://github.com/PatrickSys/codebase-context/issues/2)
## 1.2.0 (2025-12-29)
### Features
- **Actionable Guidance**: `get_team_patterns` now returns a `guidance` field with pre-computed decisions:
- `"USE: inject() – 97% adoption, stable"`
- `"AVOID: constructor DI – 3%, declining (legacy)"`
- **Pattern-Aware Search**: `search_codebase` results now include:
- `trend`: `Rising` | `Stable` | `Declining` for each result
- `patternWarning`: Warning message for results using declining patterns
- **Search Boosting**: Results are re-ranked based on pattern modernity:
- +15% score boost for Rising patterns
- -10% score penalty for Declining patterns
### Purpose
This release addresses **Search Contamination** — the proven problem where AI agents copy legacy code from search results. By adding trend awareness and actionable guidance, AI agents can now prioritize modern patterns over legacy code.
## 1.1.0 (2025-12-15)
### Features
- **Pattern Momentum**: Detect migration direction via git history. Each pattern in `get_team_patterns` now includes:
- `newestFileDate`: ISO timestamp of the most recent file using this pattern
- `trend`: `Rising` (≤60 days), `Stable`, or `Declining` (≥180 days)
- This solves the "3% Problem" — AI can now distinguish between legacy patterns being phased out vs. new patterns being adopted
### Technical
- New `src/utils/git-dates.ts`: Extracts file commit dates via single `git log` command
- Updated `PatternDetector` to track temporal data per pattern
- Graceful fallback for non-git repositories
## 1.0.1 (2025-12-11)
### Fixed
- Added `typescript` as runtime dependency (required by `@typescript-eslint/typescript-estree`)
## 1.0.0 (2025-12-11)
Initial release.
### Features
- **Semantic search**: Hybrid search combining semantic similarity with keyword matching
- **Pattern detection**: Detects team patterns (DI, signals, standalone) with usage frequencies
- **Golden Files**: Surfaces files that demonstrate all team patterns together
- **Internal library discovery**: Tracks usage counts per library, detects wrappers
- **Testing framework detection**: Detects Jest, Jasmine, Vitest, Cypress, Playwright from actual code
- **Angular analyzer**: Components, services, guards, interceptors, pipes, directives
- **Generic analyzer**: Fallback for non-Angular files (32 file extensions supported)
- **Local embeddings**: Transformers.js + BGE model, no API keys required
- **LanceDB vector storage**: Fast, local vector database
### Architecture
- Framework-agnostic core with pluggable analyzers
- Angular as first specialized analyzer (React/Vue extensible)
- tsconfig paths extraction for internal vs external import detection
