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 | $0.00210 | $0.00210 |
| Opus 5 | $0.00105 | $0.00105 |
| Sonnet 5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
ardupilot-mcp 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 10d 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
The full, tool-agnostic rules for this repo live in AGENTS.md — read it first. It covers the architecture, the golden rules (deterministic core / offline & read-only / no unsupported assumptions / keep docs in sync / tests gate everything), how to add a check, and the dev commands.
Claude-specific notes:
- Use
/add-check(.claude/commands/add-check.md) to scaffold a new diagnostic check the right way. - After any change, run
ruff check,ruff format,mypy ardupilot_mcp, andpytest. - When you add or rename a check/tool, update
README.md,CHANGELOG.md, anddocs/SOURCES.md—tests/test_docs_sync.pywill fail if you don't. - Never add network access or vehicle actuation: the server is offline and read-only by design, and that is its entire safety guarantee.
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.
