Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00038 | $0.00395 |
| Opus 5 | $0.00019 | $0.00198 |
| Sonnet 5 | $0.00008 | $0.00079 |
| Haiku 4.5 | $0.00004 | $0.00040 |
Grade A, and why
review-pr 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 11d 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.

Review Checklist
For each changed file, verify:
Correctness
- Does the code do what the PR description claims?
- Are there any logic errors or edge cases missed?
- Are error paths handled properly?
Conventions
- Are datetimes handled consistently (UTC internally)?
- Are error messages specific and actionable?
- Is async used properly (no sync I/O in async paths)?
- Are type hints present on all new functions?
- Are typed models used for data structures (not raw dicts)?
Tests
- Are new features covered by tests?
- Are edge cases tested?
- Are external APIs mocked (no real network calls)?
Security
- Are authorization checks enforced on new endpoints?
- Are there any secrets or API keys in the diff?
- Is input validation present?
Output
Provide a structured review:
- Summary: One-line assessment (approve/request changes)
- Issues: Specific problems with file paths and line numbers
- Suggestions: Optional improvements (clearly marked as non-blocking)
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.
