review

review is a skill for Claude Code from panda850819/verbs. It costs 49 tokens per session (1,074 once invoked), scanned A, original, MIT.

A code-diff review checks the files changed in a proposed commit or pull request against the requested intent and likely risks.

In plain words
What is it for?
Use it to review a branch, commit, or pull request, assess risks such as authentication or database changes, and make limited corrections when appropriate.
Why use it?
It helps catch defects, scope drift, missing coverage, and high-risk changes before they are committed or merged.

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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

The delta beyond an unstructured single-pass review is scope provenance, risk-adaptive lanes, evidence gates, bounded correction, and cold escalation.

1. Bind scope

  1. Read AGENTS.md or CLAUDE.md when present.
  2. Resolve the base from the PR, upstream, or merge-base; print the base and changed-file list. Never silently review the whole repository.
  3. Read the issue, brief, or request that defines intent. If none exists, report INTENT GAP and infer only from the diff.
  4. Check branch state and uncommitted changes; use history only to explain scope.

2. Choose the risk lane

  • low: local, reversible, with no trust boundary, persistent data, concurrency, public interface, generated contract, or production operation.
  • medium: shared behavior, multiple files, compatibility, or concurrency.
  • high: auth, secrets, money, permissions, migrations, destructive writes, production infrastructure, or unfamiliar costly behavior.

Choose the lane from the diff and intent. Promote when the first pass reveals a risk trigger, candidate finding, coverage gap, or scope drift.

Low-risk fast path

Only in the low lane with explicit scope and intent: trace the changed path, match acceptance and branches to tests, and self-refute the likeliest defect. An INTENT GAP promotes rather than entering this fast path. If no finding, gap, or drift remains: Do not load review learnings; enumerate no lenses, print no empty scope-drift or cold-review fields, and return:

Review scope: <base>..<head> | <n> files | risk: low
No actionable findings.
Coverage: <verified check>
Self-refute: <assumption and observed result>

3. Escalated review

Read lib/learning-recall.md and apply relevant repo learnings. Map the diff to security, data integrity, concurrency, architecture, or operations lenses. Medium uses only triggered lenses. High uses every relevant lens plus a cold review.

Trace changed inputs through code, callers, contracts, tests, and failure handling. A finding survives only with severity P0P3, a tight file/line range, a trigger, mechanism and user-visible consequence, and a correction direction. Exclude style, unreachable speculation, and pre-existing defects; review does not edit code.

Changes

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 panda850819/verbs (5 stars, last pushed 5d ago), licensed MIT. It adds 49 tokens to every session and 1,074 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.
