codeGraph-branch CLAUDE.md

Repository instructions for CodeGraph, a local code-intelligence library and command-line tool that maps files, symbols, and relationships into a searchable SQLite database.

In plain words
What is it for?
Use them to build or run CodeGraph, index a project, start its MCP server, execute all tests, or run one test file or pattern.
Why use it?
They show where the project components live and which commands verify changes, reducing guesswork when developing or testing the codebase.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

codeGraph-branch CLAUDE.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Project Overview

CodeGraph is a local-first code intelligence library + CLI + MCP server. It parses any supported codebase with tree-sitter, stores symbols/edges/files in SQLite (FTS5), and exposes a knowledge graph to AI agents (Claude Code, Cursor, Codex CLI, opencode) over MCP. Per-project data lives in .codegraph/. Extraction is deterministic — derived from AST, not LLM-summarized.

Distributed as @colbymchenry/codegraph on npm; same binary serves as installer, indexer, and MCP server.

Build, Test, Run

npm run build           # tsc + copy schema.sql and *.wasm into dist/; chmods dist/bin/codegraph.js
npm run dev             # tsc --watch
npm run clean           # rm -rf dist

npm test                # vitest run (all)
npm run test:watch
npm run test:eval       # only __tests__/evaluation/
npm run eval            # build then run __tests__/evaluation/runner.ts via tsx

npm run cli             # build then run the local dist binary

# Single test file / pattern
npx vitest run __tests__/installer-targets.test.ts
npx vitest run __tests__/extraction.test.ts -t "TypeScript"

copy-assets (called from build) copies src/db/schema.sql and all src/extraction/wasm/*.wasm files into dist/. Any new SQL or grammar wasm must be copied or it won't ship.

Node engines: >=18.0.0 <25.0.0. There is a hard exit on Node 25.x (see src/bin/node-version-check.ts).

Architecture

Layered pipeline

files → ExtractionOrchestrator (tree-sitter) → DB (nodes/edges/files)
              ↓
       ReferenceResolver (imports, name-matching, framework patterns)
              ↓
       GraphQueryManager / GraphTraverser (callers, callees, impact)
              ↓
       ContextBuilder (markdown/JSON for AI consumption)

The public API surface is src/index.ts — the CodeGraph class wires all the layers and re-exports types. Library users only touch this file; the MCP server and CLI also drive it.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codeGraph-branch CLAUDE.md is an instructions file published in the GitHub repository lagrahhn/codeGraph-branch (2 stars, last pushed 1mo ago), licensed MIT. It adds 7,343 tokens to every session, about $0.0367 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
