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 | $0.00445 | $0.00445 |
| Opus 5 | $0.00222 | $0.00222 |
| Sonnet 5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade B, and why
archdiagram CLAUDE.md scanned grade B 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Guidance for Claude Code when working in this repository.
Cursor↔Claude live-review bridge
A reviewer running in Cursor watches the executing agent (Claude, in the terminal) and steers it without interrupting the chat, via bridge files. This convention works in every repo (a user-scope hook activates it automatically).
- Bridge files are named
suggestions_*.md— e.g.plans/suggestions_NN_<slug>.mdbeside a plan, or a top-levelsuggestions_<topic>.md. The Cursor reviewer owns them (creates / rewrites / erases). The executor never deletes a reviewer's directives. - Claude polls the relevant
suggestions_*.mdbefore starting a task and after every task/checkbox. ## Open Directives(- [ ]) are binding. On conflict with the plan/spec body, the directive wins (the reviewer has fresher context).- Claude acknowledges under
## Claude Acknowledgements, ticking- [ ]→- [x]and referencing the code/tests that close each one. Blockers are surfaced there. - Automated — no manual nudge. A user-scope
Stophook (~/.claude/hooks/suggestions_watch.py, wired in~/.claude/settings.json) runs at the end of every turn: if asuggestions_*.mdchanged and still has unchecked directives, it blocks the stop and re-injects them. It baselines on first sight, guards against loops, and fails open. Hooks load at session start, so restart an in-flight session (or run/hooks) if the bridge does not fire. - When you are the Cursor reviewer: write
suggestions_*.mdwith a## Open Directiveslist of short, testable- [ ]items plus a## Claude Acknowledgementsheading, and reference the bridge file from the plan/spec.
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.

archdiagram CLAUDE.md is an instructions file published in the GitHub repository bharathgnana/archdiagram (3 stars, last pushed 2mo ago), licensed MIT.
