review

review is a skill for Claude Code from fivol/claude-make-better. It costs 103 tokens per session (6,821 once invoked), scanned A, original, MIT.

An in-place adversarial review workflow for an unfinished code change. It searches for correctness problems first, checks history and related projects, and fixes verified issues directly in the working tree.

In plain words
What is it for?
Use it before committing or again on the complete change to inspect bugs, missing work, duplication, design, efficiency, tests, documentation, conventions, and cross-repository integration.
Why use it?
It finds and repairs problems before a change is committed, while checking whether the change fits existing code and earlier review feedback.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions CLAUDE.md; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pack.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 468 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review — find what's wrong with this change, then fix it

gather scope → build the pack → find candidates → verify in batches → sweep → cross-repo → fix → report

Your job is not to produce a report the user reads and acts on. It is to leave the tree better than you found it and hand back a short, honest account of what you changed, what you refused to change, and what only the user can decide.

This skill runs inline, and that is the whole design

Do not run this skill in a fork, a background agent, or anything else that returns before the review is done. It is a gate: the caller must not be able to commit, push or answer the user while it is still running. A detached run has already produced the worst failure this gate has had — the caller ended its turn on the dispatch, the user asked why nothing happened, the next turn started a second full fan-out over the same worktree, and the change was committed and pushed eight minutes before either review returned. Two competing reviews, twenty-eight million tokens, and the gate's own fixes landed as loose uncommitted work on top of the push.

So: you orchestrate in this context. Only the leaf agents are separate, and they are separate for a reason that has nothing to do with hiding latency — see below.

Blindness belongs at the leaves, not at the root. The finders and verifiers see the diff and nothing else: not the task, not the chat, not the author's reasoning. That is what makes their judgement worth having. You are not blind, and that is deliberate too — you know what the change was for, which is the only way to tell a deliberate behavior change from a bug, and the one call the finders provably cannot make. What you must never do is defend the code. When a candidate lands, read the line as if a stranger wrote it.

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.
