tree-sitting

AST-powered code navigation using tree-sitter. Parses all source files in a codebase into in-memory syntax trees, then provides fast query tools for symbol search, file/directory overview, source retrieval, and reference finding.

Features

• Fast scanning — parses ~250 files in ~700ms, then all queries are sub-millisecond from cache
• Symbol search — find by exact name, substring, or glob pattern across the entire codebase
• Directory and file overview — structural summaries with symbol counts, signatures, and doc comments
• Source retrieval — fetch implementation of any symbol, preferring definitions over declarations
• Reference finding — locate all textual references to a symbol via fast grep against cached source
• 12 grammars — Python, JavaScript, TypeScript, TSX, Go, Rust, Ruby, Java, C, HTML, Markdown, Mojo. Bundled for Linux x86_64 (.so) and macOS (.dylib); scripts/build_grammars.py compiles them anywhere else.
• Three-tier extraction — custom extractors (richest), community tags.scm queries, and generic heuristic fallback
• Dual deployment — direct Python calls in Claude.ai, or long-lived MCP server in Claude Code

Dependencies

• tree-sitter — bare parser runtime
• Python 3.10+ — the grammars are ABI 15, which needs the tree-sitter >= 0.25 binding
• fastmcp — required only for MCP server mode (Claude Code)
