code-review

code-review is a skill for Claude Code, Codex from mrclrchtr/supi. It costs 44 tokens per session (1,054 once invoked), scanned A, a copy of code-review, MIT.

A two-part code review for changes made after a specified commit, branch, tag, or merge base. One review checks the repository's coding standards, and the other checks whether the requested issue or specification was followed.

In plain words
What is it for?
Use it to review a branch or working tree against a fixed point and receive standards and specification findings side by side.
Why use it?
It separates style and project-rule concerns from the question of whether the change solves the requested problem. This makes gaps easier to identify.

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

code-review 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 1mo 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code review

Use review_run for this workflow. It freezes one Review Target and runs the Standards and Spec tasks independently. Keep their results separate. If review_run is unavailable, report that this workflow is unavailable. Do not replace it with agent_run or generic agents.

Process

1. Resolve the Review Target

Identify the before and after states once.

  • For committed changes since a branch or tag, resolve the merge base with git merge-base <fixed-point> HEAD. Pass that full commit as committed.from and pass HEAD as committed.to.
  • If the user gives two exact endpoints, resolve each endpoint and pass them as committed.from and committed.to.
  • To include staged, unstaged, or non-ignored untracked files, use workingTree.from. Use the merge base for branch work, or HEAD for work-in-progress changes only.
  • For a state audit, use mode: "state" and omit from.

Review endpoints must resolve to commits. Do not pass Git range syntax to review_run. If the request is not a state audit or a work-in-progress review and no fixed point is available, ask for one.

2. Identify the Spec source

Search in this order:

  1. Issue references in commit messages. Use the repository issue workflow when one exists.
  2. A path or issue that the user supplied.
  3. A specification under docs/, specs/, or .scratch/ that matches the branch or change.
  4. Ask the user when no source is available. If the user confirms that there is no Spec, omit the Spec task and state this in the report.

Record each authoritative source as a criteriaSources item with a useful summary.

3. Identify the Standards sources

Find repository instruction files, contribution guides, coding standards, and relevant package-local guidance. Reviewers do not receive ambient context files. Put each necessary rule in the task instructions or identify its repository file in criteriaSources.

Apply this smell baseline as advisory criteria. A documented repository rule overrides it. Report each match as a judgment, not as a hard violation. Skip checks that automated tooling already enforces.

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.
