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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.07343 | $0.07343 |
| Opus 5.5 | $0.02937 | $0.02937 |
| Sonnet 5.5 | $0.01469 | $0.01469 |
| Haiku 4.5 | $0.00734 | $0.00734 |
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 1mo 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
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.
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 (3 stars, last pushed 3mo ago), licensed MIT. It adds 7,343 tokens to every session, about $0.0294 per session on Opus 5.5. 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.
