codesteward-graph CLAUDE.md

Repository instructions for Codesteward Graph, a Model Context Protocol server that parses source code into a searchable graph of repository structure and relationships.

In plain words
What is it for?
Use them when developing or operating the graph server, choosing Neo4j, JanusGraph, or embedded SQLite storage, or working across its package workspace.
Why use it?
They explain the project's boundaries, architecture, and supported graph databases so changes fit the intended design.

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 A, and why

codesteward-graph CLAUDE.md scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md — Codesteward MCP Graph Server

What This Is

This is the Phase 1 standalone repository of the Codesteward platform. It is a self-contained Model Context Protocol server that parses source repositories into a structural code graph and exposes that graph as queryable tools for AI agents.

It has no dependency on the broader Codesteward agent platform (no deepagents, no LangChain, no workflows, no policy engine, no PostgreSQL). For graph storage it supports three backends: Neo4j, JanusGraph (Apache 2.0), or GraphQLite (embedded SQLite — no server needed, ideal for local dev via uvx).

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.
