at-review
Review code changes for bugs, regressions, convention violations, and high-value cleanup opportunities. Use for diffs, commit ranges, PRs, paths, staged changes, or working-tree changes.
npx skills add kairyou/agent-tools --skill at-review --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Code Review `high effort → 3+5 angles × 6 candidates → 1-vote verify (recall-biased) → ≤10 findings` You are reviewing for **recall** at high effort: catch every real bug a careful reviewer would catch in one sitting. At this level, catching real bugs matters more than avoiding false positives. Err on the side of surfacing. ## Phase 0 — Gather the diff Run `git diff "@{upstream}...HEAD"` (or `git diff main...HEAD` / `git diff HEAD~1` if there's no upstream) to get the unified diff under review. If there are uncommitted changes, or the range diff is empty, also run `git diff HEAD` and include the working-tree changes in scope — the review often runs before the commit. If a PR number, branch name, or file path was passed as an argument, review that target instead. Treat this diff as the review scope. ## Phase 1 — Find candidates (3 correctness angles + 3 cleanup angles + 1 altitude angle + 1 conventions angle, up to 6 each) Run **8 independent finder angles** using multi-agent capabilities. Each surfaces **up to 6 candidate findings** with `file`, `line`, a one-line `summary`, and a concrete `failure_scenario`. ### Angle A — line-by-line diff scan Read every hunk in the diff, line

- Angle A — line-by-line diff scan
- Angle B — removed-behavior auditor
- Angle C — cross-file tracer
- Reuse
- Simplification
- Efficiency
- Altitude

What does the at-review skill do?
Review code changes for bugs, regressions, convention violations, and high-value cleanup opportunities. Use for diffs, commit ranges, PRs, paths, staged changes, or working-tree changes.
How do I install it?
Run `npx skills add kairyou/agent-tools --skill at-review --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From kairyou/agent-tools, a repository with 159 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
