CodeGraph is a local, pre-indexed knowledge graph of a software codebase that helps AI coding agents understand relationships across files and symbols. Developers use it to retrieve focused code context, keep the graph synchronized with changes, and support agents such as Claude Code, Codex, Cursor, and Gemini. The catalogue entries provide CodeGraph skills and instructions for those agent workflows.

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 | $0.00172 | $0.00172 |
| Opus 5.5 | $0.00069 | $0.00069 |
| Sonnet 5.5 | $0.00034 | $0.00034 |
| Haiku 4.5 | $0.00017 | $0.00017 |
Grade A, and why
codegraph 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 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.
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.

What it actually says
CLAUDE.md
Claude Code project guidance for this repository.
Primary instructions live in the canonical agent guide — import it:
@AGENTS.md
Claude-only notes
- Prefer the repo-root
AGENTS.mdas the source of truth for build/test/architecture/house rules. Edit that file (not this wrapper) when guidance changes. - Claude Code can
@-import nested guides too (e.g.@docs/AGENTS.md) when working on design/eval docs; Codex loads nestedAGENTS.mdautomatically when the session cwd is under that directory. - Do not reintroduce a duplicated
## CodeGraphMCP tool-guidance block here —src/mcp/server-instructions.tsis the single source of truth (issue #529); the installer strips legacy marker blocks on upgrade.
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.
