review is a skill for Claude Code from smartwhale8/claude-playbook. It costs 13 tokens per session (484 once invoked), scanned A, original, MIT.

A review procedure for checking uncommitted code changes against a project's standards before committing them to version control.

In plain words
What is it for?
Use it to inspect staged or unstaged changes, review new files, and assess code quality, architecture, consistency, and reuse.
Why use it?
It helps find dead code, inconsistent patterns, duplicated work, architecture problems, and other issues before changes are saved to the project history.

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 11d 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

Review all uncommitted changes in this project. $ARGUMENTS

Process

  1. Gather changes: Run git diff --staged for staged changes, or git diff if nothing is staged. Also check git status for new untracked files.

  2. Check each changed file against the project rules (.claude/rules/*.md):

    Code Quality

    • Is there dead code, unused imports, or commented-out code?
    • Are there bandaid fixes or workarounds instead of root-cause solutions?
    • Is anything over-engineered for what it needs to do?

    Architecture

    • Does this follow existing patterns in the codebase?
    • Is there duplicate logic that should use an existing shared component or utility?
    • Are dependencies pointing in the right direction (inward, not outward)?

    Consistency

    • Does the code match the style and structure of similar files in the project?
    • For frontend: are spacing, colors, and component usage consistent with the rest of the UI?
    • For backend: are error handling, response format, and validation patterns consistent?

    Reuse

    • Could any new component, function, or pattern already exist in the codebase? Search before approving.
    • If something similar exists, flag it — it should be reused or extracted into a shared utility.

    Security

    • Any hardcoded secrets, credentials, or API keys?
    • Is user input validated at the boundary?
    • Are there SQL injection, XSS, or other OWASP risks?

    Performance

    • Any N+1 query patterns (database calls inside loops)?
    • Any unbounded queries missing LIMIT/pagination?
    • Frontend: unnecessary re-renders, missing debounce on inputs?
  3. Verdict: Provide one of:

    • Ready to commit — no issues found
    • Minor issues — list them, but committing is acceptable after acknowledging
    • Needs changes — list specific issues that must be fixed before committing

For each issue, provide: the file, the line(s), what's wrong, and what the fix should be.

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 smartwhale8/claude-playbook (37 stars, last pushed 6mo ago), licensed MIT. It adds 13 tokens to every session and 484 once invoked, about $0.0001 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 2026-08-30.
