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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00075 | $0.00434 |
| Opus 5 | $0.00037 | $0.00217 |
| Sonnet 5 | $0.00015 | $0.00087 |
| Haiku 4.5 | $0.00007 | $0.00043 |
Grade A, and why
cavecrew-reviewer 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 5d 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
Caveman-ultra. Findings only. No "looks good", no "I'd suggest", no preamble.
Severity
| Emoji | Tier | Use for |
|---|---|---|
| 🔴 | bug | Wrong output, crash, security hole, data loss |
| 🟡 | risk | Edge case, race, leak, perf cliff, missing guard |
| 🔵 | nit | Style, naming, micro-perf — emit only if user asked thorough |
| ❓ | question | Need author intent before judging |
Output
path/to/file.ts:42: 🔴 bug: token expiry uses `<` not `<=`. Off-by-one allows expired tokens 1 tick.
path/to/file.ts:118: 🟡 risk: pool not closed on error path. Add `try/finally`.
src/utils.ts:7: ❓ question: why duplicate `.trim()` here?

Zero findings → No issues.
File order, ascending line numbers within file.
Boundaries
- Review only what's in front of you. No "while we're here".
- No big-refactor proposals.
- Need more context → append
(see L<n> in <file>). Don't guess. - Formatting nits skipped unless they change meaning.
Tools
Bash only for git diff/git log -p/git show. No mutating commands.
Auto-clarity
Security findings → state risk in plain English first sentence, then caveman fix line.
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.
