review

review is a skill for Claude Code, Codex from MatrixAges/polywise. It costs 54 tokens per session (248 once invoked), scanned A, original, MIT.

A code-review procedure for examining uncommitted changes. It looks for design problems, incomplete requirements, bugs, duplicated work, missing checks, and possible improvements.

In plain words
What is it for?
Reviewing pending changes, reporting findings with file references, fixing issues when requested, and checking the result afterward.
Why use it?
It helps reviewers focus on the highest-impact problems instead of producing only a summary of the diff.

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 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 today.

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

Review

Inspect the current working tree before making assumptions. Start with git status --short, then read the relevant diff.

Prioritize findings over summaries. Report the highest-impact issues first with precise file references and concrete impact.

Check these areas on every run:

  • Find unreasonable or fragile design choices.
  • Find unfinished requirements or behavior gaps.
  • Find potential bugs, regressions, and edge-case failures.
  • Find duplicated logic or places where existing code should have been reused.
  • Find missing validation, verification, or tests.

When the user expects action instead of commentary, fix the issues you identify and re-check the result.

When reviewing, keep the response structure tight:

  • List findings first, ordered by severity.
  • Add open questions or assumptions only if they materially affect correctness.
  • Add a short change summary only after the findings or fixes.

When no issues are found, say so explicitly and still mention residual risks or missing verification.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
