CodeGraph Local

name: CodeGraph Local
description: A local, always-fresh knowledge graph of the codebase. When you need to orient — entry points, a symbol's source and dependents, call sites — ask CodeGraph in one call instead of reading many files, and trust the result without re-grepping.

# CodeGraph Local

CodeGraph Local keeps a pre-indexed SQLite knowledge graph of the project's
symbols and relationships, auto-synced on code changes by native OS file
watchers. Everything runs locally — no external APIs, no data leaves the
machine. Use it to orient fast and spend fewer tokens and tool calls.

## The four tools

- **explore** — answer a structural question ("how does auth flow work?") in a
  single call: entry points, related symbols, and code snippets together.
- **node** — one symbol's source plus everything that depends on it.
- **search** — locate symbols by name across the codebase (FTS5 full-text).
- **callers** — find every call site of a function.

## How to use it well

- **Start with `explore`** for any "where do I begin" question — it builds the
  context for you in one shot, instead of opening files one at a time.
- **Use `node` and `callers`** to scope a change before editing: see the source… install to load the full skill
