review-code

review-code is a skill for Claude Code from patforna/auto-task. It costs 51 tokens per session (2,416 once invoked), scanned C, original, MIT.

A read-only review process for checking a code difference, such as a commit, branch range, or pull request, for defects, design problems, security issues, and project conventions.

In plain words
What is it for?
Use it to review a proposed change. It reports findings and possible mechanical patches but does not apply fixes, and it requires a fresh session for a full review of code written in the current session.
Why use it?
It focuses attention on findings an author would likely fix and separates serious release-blocking problems from minor mechanical fixes.

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 C, and why

review-code scanned grade C with 1 finding 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Usage

/at:review-code [diff target] [further instructions]

Diff target: a commit, a commit range, a base branch, PR ref, etc.

Goal

Surface the small set of findings a competent author would fix if they saw them, and capture mechanically-certain trivia as ready-to-apply patches.

Notes

  • Most findings are expected to be around design and evolvability, not defects.
  • Defects are the high-severity minority that gates the ship.
  • You classify, you do not fix: emit the fix, never apply it.

Authorship Guard

This must be run by a different model, or at least in a fresh session, as same-context self-review is fundamentally flawed.

If you authored the diff under review in the current session, or there is no diff target:

  • warn the user that same-context self-review is structurally unreliable and advise re-invoking from a fresh session.
  • if declined, downgrade review scope to: convention, CLAUDE.md, project-rule conformance, the do-not-flag filter, and the autofix lane only. Do NOT run an open correctness / logic / security pass in this context. A user override may only further restrict scope — never re-authorise the open pass in the same context.

The Do-Not-Flag List

Drop, do not surface:

  • Pre-existing issues — anything this diff did not introduce or worsen.
  • Tool-owned — lint, formatting, type errors, test failures. The deterministic gate runs separately; never duplicate it.
  • Correct-but-unusual — unconventional but provably correct is not a finding.
  • Framework-handled — errors or validation the framework already guarantees.
  • Speculative — anything you cannot pin to a file:line with a concrete failure mechanism.
  • Judgement-bound trivia — taste-level naming or structure where reasonable authors differ and nothing is measurably wrong.

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.
