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 | $0.00040 | $0.00230 |
| Opus 5 | $0.00020 | $0.00115 |
| Sonnet 5 | $0.00008 | $0.00046 |
| Haiku 4.5 | $0.00004 | $0.00023 |
Grade A, and why
monitor-evals 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 2d 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
Monitor evaluation history
Read versioned run manifests with helpers.evals.monitoring.load_history. Use classify_changes before comparing scores.
Separate:
- system behavior changes;
- data changes;
- task-mix or suite-version changes;
- evaluator changes; and
- operational failures such as blocked tools or expired connections.
Compare only compatible runs. Show per-case and slice movement, not only the aggregate. Run frozen sentinel examples for model graders so evaluator drift does not look like system drift.
Apply the named operating rule:
- continue when the intended change improved the target slice without a blocking regression;
- investigate when the cause is unclear or several inputs changed;
- rollback when a blocking regression follows a controlled system change; or
- escalate when the evaluator, data, or authorization boundary may be invalid.
Record the owner and next action. Monitoring is an operating practice, not a dashboard someone passively observes.
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.

monitor-evals is a skill published in the GitHub repository ai-analyst-lab/ai-analyst (298 stars, last pushed 3d ago), licensed MIT. It adds 40 tokens to every session and 230 once invoked, about $0.0002 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 2026-09-12.
