review

review is a skill for Claude Code, Codex from fullymiddleaged/Clawness. It costs 43 tokens per session (347 once invoked), scanned A, original, MIT.

An adversarial review of staged code changes or a specified file, carried out by a code-critic agent. It looks for correctness bugs, performance problems, missed edge cases, and maintainability issues.

In plain words
What is it for?
Reviewing staged changes, recently changed files, or selected files before committing or merging, then reporting findings with their location, severity, and suggested fix.
Why use it?
A normal change check can miss failures that appear only with unusual inputs, concurrency, or larger workloads. This review gives a focused second examination before a commit or merge.

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 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.

What it actually says

Adversarial Code Review

Run a thorough code review using the Clawness code-critic agent.

Before spawning the agent: if you surfaced this proactively (the user mentioned reviewing/merging but didn't explicitly ask to run it), first ask: "Want me to run the adversarial code review now?" Proceed only once they confirm. If the user explicitly invoked /clawness:review or already said yes, skip the question.

Steps

  1. Identify changes — If $ARGUMENTS specifies files, review those. Otherwise, check for staged git changes (git diff --cached). If nothing is staged, review the most recently changed files (git diff HEAD~1).

  2. Delegate to code-critic — Send the relevant code to the code-critic sub-agent for adversarial review focusing on:

    • Correctness bugs and logic errors
    • Performance issues (N+1, re-renders, memory leaks)
    • Missing edge cases (null, empty, concurrent, malicious)
    • Maintainability (naming, complexity, duplication)
  3. Report — Present findings grouped by severity. For each finding, include the file, line, problem, and suggested fix.

  4. Offer to fix — Ask the user if they want to apply any of the suggested fixes.

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.

review is a skill published in the GitHub repository fullymiddleaged/Clawness (3 stars, last pushed 6d ago), licensed MIT. It adds 43 tokens to every session and 347 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.
