Overview

Parses a repository with Tree-sitter into a SQLite graph of functions, classes, imports, calls, inheritance and tests, then serves blast-radius and review context to AI coding tools over MCP. A single install command detects and configures about 16 tools, including Claude Code, Cursor, Codex, Windsurf and Zed. It also ships a GitHub Action that posts risk-scored PR comments, and updates the graph incrementally by SHA-256 hash.

Who it is for: Developers using AI coding assistants on large repos who want less token use

Strengths

  • One install command configures about 16 coding tools; uninstall leaves other config intact
  • Incremental re-parse by SHA-256; two-file edit on a ~3,000-file repo took about 2.5 s
  • Covers 30+ languages and notebooks, plus custom languages via languages.toml
  • Pinned-SHA benchmarks with a reproduction recipe; median 63x token reduction across 6 repos

Weaknesses

  • Impact recall of 1.0 is circular, since ground truth comes from the same graph
  • Graph context can exceed a plain file read for small single-file edits
  • Search ranking needs work; Express queries can return no hits
  • Flow detection is strongest for Python and PHP/Laravel; JavaScript and Go are weaker

What it needs

  • no GPU
  • Needs Python 3.10+, Tree-sitter, SQLite
  • Models: sentence-transformers (all-MiniLM-L6-v2), Google Gemini, MiniMax, Voyage AI, OpenAI-compatible endpoints
