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 | $0.00037 | $0.00706 |
| Opus 5 | $0.00018 | $0.00353 |
| Sonnet 5 | $0.00007 | $0.00141 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
review-conformance 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Conformance Review (first pass, before quality)
Wrong-but-clean code is worse than ugly-but-right code. Check conformance FIRST.
Three-level check
- Requirement conformance — For each acceptance criterion of the task: point at the exact code/test that satisfies it. No pointer = finding. Check scope both ways: nothing promised is missing, and nothing out-of-scope was touched (the
diff.statuslist shows every file — files outside the task's declaredFiles:list need justification). - Plan/architecture conformance — Does the implementation follow the approved design: same components, same data flow, same chosen option? Check the code against PLAN.md's Contracts — signatures, data shapes, and API/event contracts must match what was agreed, because other tasks were sliced and reviewed assuming them; a silently changed contract breaks callers this task can't see. Codex substituting its own design is a finding even when it works — the plan was reviewed, the substitute wasn't. If the deviation is genuinely better, surface it to the user as a plan change, don't wave it through.
- Structure conformance — Files in the right places, naming matching conventions, integration through existing seams (not parallel copies of existing helpers), tests where the project keeps tests.
Evidence rules
- Check the tool result's
statusfield first: only review asuccessrun normally. Apartialrun (no completion marker / parse errors) means the result may be incomplete — verify everything from the diff and your own check runs, or re-run the task (seereview-feedback). - When the run carried a
verifyCommand, read theverificationfield before anything else:passed: trueproves the acceptance command exited 0 in the workspace;passed: falseorskippedis an automatic unmet criterion — quote itsoutputTailin the finding. - Work from the tool result's
difffield (status + patch); read full files when the patch lacks context. Never review from Codex'sagentMessagealone — it describes intent, not reality. - Do not re-run the suite per task: read
acceptedandverification(the server-runverifyCommand) as the acceptance evidence, and run a manual probe only when the acceptance is not a command.commandsin the result shows what Codex ran and exit codes — confirm the targeted tests plus build/typecheck ran green; Codex is not expected to run the full suite (it runs once per merged parallel wave and once in the whole-feature review).
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.

review-conformance is a skill published in the GitHub repository anhnguyen0905/codex-mcp (3 stars, last pushed today), licensed MIT. It adds 37 tokens to every session and 706 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 2026-08-31.
