Changelog

[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 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 in #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
