code-review

code-review is a skill for Claude Code, Codex from julien777z/agent-sync-action. It costs 129 tokens per session (7,530 once invoked), scanned A, original, MIT.

A code-review workflow for a GitHub pull request or the changes in the current working branch. It uses independent review perspectives and rates findings by severity.

In plain words
What is it for?
Reviewing pull requests or local changes, optionally applying small fixes for confirmed findings, and optionally adding review comments. If no pull request exists, it can create a branch and draft one.
Why use it?
It helps identify and validate problems before code is merged, while separating real issues from duplicates, outdated comments, or incorrect reports.

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 4d 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 — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Provide a code review for the selected target.

Dependencies

  • code-simplify — supply the complete simplification rubric for that review lens.
  • security-audit — supply the complete security rubric and attack-class catalogue for that review lens.
/code-review [low|medium|high|xhigh|max|ultra] [fix] [comment] [<target>]

Arguments

Arguments may appear in any order, and the -- prefix on a mode is optional: fix and --fix mean the same thing, as do comment and --comment. /code-review medium fix is a valid invocation.

Read the tokens as follows:

  • A token matching an effort level sets the effort.
  • A token matching fix or comment, with or without a leading --, enables that mode.
  • Any remaining token is the <target>. To review a ref whose name collides with a reserved word, pass it as a fuller ref such as refs/heads/fix.

Ask for anything the invocation did not state, before doing anything else. The invocation states two things independently, and each unstated one is a question:

  • Effort — stated by an effort token. Otherwise ask which level to run.
  • Modes — stated by the presence of any mode token, which turns the named modes on and leaves the unnamed ones off. When no mode token appears at all, ask which modes to enable.

So a bare /code-review asks both, /code-review high asks only about modes, /code-review fix asks only about effort, and /code-review high fix asks nothing and runs. A <target> never triggers a question; it has a defined fallback when absent.

When asking for effort, list every accepted value explicitly and describe its actual coverage and validation depth:

  • low — Run one Rules lens and one Bugs lens with inline validation for a quick review of small, low-risk changes.
  • medium — Run one Rules, Bugs, Contracts & comments, History, Simplification, and Security lens for a routine contextual review, with inline validation.
  • high — Run one Rules, two independent Bugs, one Contracts & comments, one History, one Prior PRs, one Simplification, and one Security lens, then have one standard validator try to refute every finding.
  • xhigh — Run two independent Rules and Bugs lenses plus one Contracts & comments, History, Prior PRs, Simplification, and Security lens, then use two standard validators per finding with majority rule.
  • max — Run two Rules, three Bugs, two Contracts & comments, two History, two Prior PRs, two Simplification, and two Security lenses in one pass, then use three deep refuters per finding with majority rule.
  • ultra — Repeat the max cohort until two consecutive rounds find nothing new, using the same three deep refuters per finding.

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.
