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 | $0.03165 | $0.03165 |
| Opus 5 | $0.01582 | $0.01582 |
| Sonnet 5 | $0.00633 | $0.00633 |
| Haiku 4.5 | $0.00316 | $0.00316 |
Grade A, and why
repo-graph CLAUDE.md scanned grade A 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Is
A thin Python MCP server that wraps the glia Rust engine (crate repo-graph-py, PyPI repo-graph-py). It exposes 6 MCP tools — orient, find, impact, trace, read, refresh — over any codebase. Each is a natural verb backed by an engine primitive (v0.4.18: blast_radius, cross_stack_trace, resolve, coverage, governing_docs), so the wrapper stays thin — the engine owns ranking, file/line locating, and the live (dead-code) flag.
The Python side is ~900 lines across 4 files. All parsing, graph building, storage (.gmap), activation, ranking, locating, and liveness happen in Rust. The Python package only hosts the MCP server, the CLI entrypoints, and a thin wrapper over the pyo3 bindings.
Commands
# Install (editable, for development)
pip install -e .
# Run the MCP server (points at a target repo)
repo-graph --repo /path/to/target-repo
# Initialise a new target repo (writes .mcp.json + CLAUDE.md instructions + first graph)
repo-graph-init --repo /path/to/target-repo
Python 3.11+ required. Runtime deps: mcp[cli]>=1.0.0, repo-graph-py>=0.4.16.
Cache reuse on cold start
Since engine v0.4.14 the wrapper caches the graph at <repo>/.ai/repo-graph/ (sharded .gmap files). On every server start get_graph() checks is_stale(gmap_dir, repo_path):
- Fresh cache →
load_from_gmap()(≈10× faster than re-scanning; a 22k-node repo loads in ~250ms instead of ~2.8s). - Stale or missing →
generate()+save_to_default()so the next cold start is fast.
Cache writes are best-effort: a read-only filesystem or perms error doesn't break the live graph. The generate MCP tool always writes the cache after a successful scan; the reload tool now forces a real re-generate (not just a .gmap reload), so edits between calls always show up. Source-tree change detection for the .gmap staleness check is mtime-based and skips .git, target, node_modules, .venv, __pycache__, .ai/.
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.

repo-graph CLAUDE.md is an instructions file published in the GitHub repository James-Chahwan/repo-graph (15 stars, last pushed 2mo ago), licensed MIT. It adds 3,165 tokens to every session, about $0.0158 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
