review

review is a skill for Claude Code from wyattowalsh/agents. It costs 36 tokens per session (4,359 once invoked), scanned A, original, MIT.

A read-only inspection tool for code, diffs, pull requests, repositories, and external sources. It reports evidence-backed findings and can also review proposed simplifications or source provenance.

In plain words
What is it for?
Use it for session, pull-request, range, full-audit, security, frontend, accessibility, provenance, and behavior-preserving simplification reviews.
Why use it?
It helps identify problems and risks before code is changed, while keeping the review focused on the selected scope.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00036 $0.04359
Opus 5.5 $0.00014 $0.01744

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 1mo ago.

The scan reads SKILL.md. This mod also ships 14 executable files (scripts/asset_toolkit/__init__.py, scripts/asset_toolkit/_shared.py, scripts/asset_toolkit/common.py, …), 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.

How it starts

The opening of the file, as written. The whole thing — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review

Use /review as the canonical first-party review entrypoint. It covers code review, session diffs, scoped files, PRs, full audits, behavior-preserving simplification review, source/provenance review for external skills, specialist audit lenses, browser-grounded frontend/a11y/web-quality review, review history, delta reports, false-positive learnings, SARIF output, Conventional Comments output, and approval-gated fix passes.

honest-review, simplify, and external-skill-auditor are not separate skills. Their behavior lives here as /review, /review simplify, and /review source.

Default posture: read-only, evidence-first, and scoped. Do not perform feature work, broad rewrites, installs, or fixes until the user explicitly approves selected findings or invokes a mode that permits edits and passes its gates.

Canonical Vocabulary

Use these canonical terms exactly.

Term Meaning
review Evidence-first inspection of code, diffs, PRs, repositories, sources, or proposed simplifications
scope The exact files, directories, PR, git range, source, or snippet under review
triage First pass that classifies scope, risk, changed files, specialist lenses, and validation requirements
finding A discrete issue with citation, reasoning, severity, confidence, evidence, and recommended action
strength A positive review observation that explains what should be preserved
confidence Score from 0.0 to 1.0; report >= 0.7, mark 0.3-0.7 unconfirmed, discard < 0.3 unless P0/S0
severity Priority/scope classification such as P0-P3 and S0-S3
citation anchor A verified [file:start-end] source location or source/provenance anchor
reasoning chain Why the finding matters, written before the finding statement
evidence Tool, source, test, docs, grep, dependency, or research proof that supports or rejects a finding
lens Specialist perspective such as security, supply chain, CI, SQL, data, frontend, a11y, web quality, MCP, agentic, or docs
skill asset A SKILL.md, skill directory, skill eval, skill script, reference, package, catalog row, or generated skill doc reviewed through skill-creator structural patterns
simplification lens Behavior-preserving review of complexity, invariants, semantic-change risk, and clarity opportunities
source/provenance lens Review of external skill/source trust, executable surfaces, owner, license, credentials, network behavior, and dedupe
approval gate Mandatory pause before editing files or applying fixes
learning Stored false-positive dismissal used to reduce repeated noise in future reviews
mode Explicit or inferred review workflow such as session, scoped, PR, range, audit, simplify, source, history, delta, learnings, or fix
shard map Wave 0 ownership plan for large parallel reviews, with lane IDs, shard IDs, file/source ownership, coverage expectations, and merge status

What ships with it

36 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
