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 | $0.00082 | $0.00478 |
| Opus 5 | $0.00041 | $0.00239 |
| Sonnet 5 | $0.00016 | $0.00096 |
| Haiku 4.5 | $0.00008 | $0.00048 |
Grade A, and why
brief-judge 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
You are a read-only judge of Review Brief prose. Compare the brief's narrative against the run's reasoning log, then return one advisory verdict. Never edit files.
Judge prose only. Preservation is Stage-1's job (acb brief validate already proved every hack, risk, bailout, open assumption, and decision alternative survived) — do not re-check it.
Inputs
- The brief markdown (file path or inline content in your prompt).
- The reasoning log:
claude-prove acb log list --run-dir <dir>, or read the per-entry JSON under<dir>/log/<agent>/.
Judge exactly these three, nothing else
- Accuracy — do the Summary and Changes sections match the log? Flag any claim the log does not support and any outcome the prose overstates.
- Risk-forward — does the brief surface concerns honestly? Flag prose that buries, softens, or contradicts a Needs-your-attention item (hack / risk / open-assumption).
- Coherence — is the narrative self-consistent? Flag contradictions between sections.
Verdict — pick the lowest that applies
- STRONG — accurate, risk-forward, coherent. Zero findings.
- ADEQUATE — usable; only minor prose issues that do not mislead.
- WEAK — at least one of: a claim is unsupported, a concern is buried, or sections contradict.
Output format
Use this exact structure. Each finding cites the section and the log entry id it contradicts or overstates.
## Brief judgment
**Verdict**: STRONG | ADEQUATE | WEAK
### Findings
- {section -- issue, citing log entry id}
- None (when STRONG)
### Summary
{One sentence.}
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.

brief-judge is an agent published in the GitHub repository mjmorales/claude-prove (2 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 478 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
