What it does

Autoreview is an agent skill from swyxio/skills. Perform a structured final code review of a local diff, commit, branch, or pull request. Use only when the user explicitly asks for autoreview, a second review, or a final review before commit, merge, or release, or when repository instructions require one. Do not trigger automatically for ordinary non-trivial edits.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Pull requests. The repository describes itself as: Agent skills for Claude Code and other AI agents. The licence is MIT.

When your agent uses it

  • Explicitly asks for autoreview
  • A second review
  • A final review before commit
  • Repository instructions require one

Example prompts

  • “/autoreview”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. correctness and violated invariants;
  2. security, privacy, authorization, and unsafe data handling;
  3. error handling, retries, concurrency, cleanup, and partial failure;
  4. compatibility with persisted state and public contracts;
  5. missing or misleading tests;
  6. unnecessary complexity introduced by the change.

What it can do on your machine

Read from SKILL.md and the folder at commit 038ef34. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Autoreview loads about 548 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 257 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~548

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Perform a structured final code review of a local diff, commit, branch, or pull request. Use only when the user explicitly asks for autoreview, a second review, or a final review before commit, merge, or release, or when repository instructions require one. Do not trigger automatically for ordinary non-trivial edits.

Auto Review

Review the completed change as a closeout check. Use the review capability available in the current environment; do not make completion depend on a particular helper, model, service, or installation.

Select the real change

  • For dirty work, review the staged, unstaged, and relevant untracked diff.
  • For a commit, review that commit and its immediate context.
  • For branch or pull-request work, compare against the actual base branch.
  • Do not push, rewrite history, or manufacture a diff merely to make review possible.

Review priorities

Inspect the changed code and adjacent ownership boundaries for:

  1. correctness and violated invariants;
  2. security, privacy, authorization, and unsafe data handling;
  3. error handling, retries, concurrency, cleanup, and partial failure;
  4. compatibility with persisted state and public contracts;
  5. missing or misleading tests;
  6. unnecessary complexity introduced by the change.

Prefer concrete defects with a reproducible path. Reject speculative edge cases, style-only churn, unrelated rewrites, and fixes that cost more complexity than the risk warrants.

Verify findings

  • Treat every finding as advisory until confirmed against the real code path.
  • Read adjacent code, types, tests, and authoritative dependency documentation when needed.
  • Fix accepted findings at the narrowest correct ownership boundary.
  • Rerun affected tests after review-driven edits.
  • Re-review only the changed result when a fix could have introduced another defect.

Stop when no confirmed actionable findings remain. Do not seek extra reviewers or repeat a clean review solely for more reassuring wording.

Report

Include:

  • the target reviewed;
  • findings accepted and rejected, with brief reasons;
  • fixes made and tests run;
  • remaining risks or verification gaps.
