review-conformance

review-conformance is a skill for Claude Code, Codex from anhnguyen0905/codex-mcp. It costs 37 tokens per session (706 once invoked), scanned A, original, MIT.

A review checklist for comparing completed work with the agreed requirements, technical plan, file scope, and acceptance criteria. It checks whether the implementation does what was requested before focusing on code quality details.

In plain words
What is it for?
Use it after implementation to verify each acceptance criterion, architecture decision, data or API contract, and changed-file boundary.
Why use it?
It catches cleanly written work that solves the wrong problem, omits a requirement, changes an agreed interface, or modifies files outside the task.

Token cost

What it costs to keep this loaded

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.

Security

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.

Conformance Review (first pass, before quality)

Wrong-but-clean code is worse than ugly-but-right code. Check conformance FIRST.

Three-level check

  1. 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.status list shows every file — files outside the task's declared Files: list need justification).
  2. 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.
  3. 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 status field first: only review a success run normally. A partial run (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 (see review-feedback).
  • When the run carried a verifyCommand, read the verification field before anything else: passed: true proves the acceptance command exited 0 in the workspace; passed: false or skipped is an automatic unmet criterion — quote its outputTail in the finding.
  • Work from the tool result's diff field (status + patch); read full files when the patch lacks context. Never review from Codex's agentMessage alone — it describes intent, not reality.
  • Do not re-run the suite per task: read accepted and verification (the server-run verifyCommand) as the acceptance evidence, and run a manual probe only when the acceptance is not a command. commands in 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).

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.
