review is a skill for Claude Code from matteocervelli/llms. It costs 84 tokens per session (3,168 once invoked), scanned B, original, MIT.

A workflow that sends code, pull requests, documents, or design questions to other AI systems for an independent review.

In plain words
What is it for?

Why use it?
It provides a second opinion on changes, architecture, documentation, types, comments, or implementation progress.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; runs codex exec; mentions Codex.

This is matteocervelli/llms's own configuration. It tells Claude Code how to work on llms itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llms configures →

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 B, and why

review scanned grade B with 1 finding 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.

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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Review — Companion-Dispatched Reviews & Analysis

Unified skill for all companion AI reviews. Dispatches structured prompts to external AIs (Codex, Gemini, Claude) via runner.sh for independent second opinions.

For Claude-native code quality checks (no external AI), use /code-review.

Usage

/review                              # Auto-detect: uncommitted changes → changes review
/review changes                      # Full review: code + silent-failures + types + comments
/review changes --quick              # Code review only (skip silent-failures/types/comments)
/review pr [--pr N]                  # PR merge readiness (MERGE/BLOCK verdict)
/review doc <file>                   # PRP/PRD/RFC/Design completeness review
/review solve "problem"              # Architecture/design second opinion
/review status <spec>                # Implementation progress vs spec
/review frontend <url>               # Delegates to /frontend review
/review silent-failures [file|diff]  # Error handling audit
/review types [file]                 # Type design analysis
/review comments [file]              # Comment accuracy check
/review gate                         # Lightweight pre-commit gate (critical bugs + security only)
/review adversarial                  # Adversarial review: challenge design choices (Codex gpt-5.5 xhigh)

All subcommands support: [companion] (codex/gemini/claude), --model MODEL, --all, --exclude-self

Workflow

Step 1: Parse Arguments

Parse $ARGUMENTS for subcommand and flags:

  • First positional arg → subcommand (changes, pr, doc, solve, status, frontend, silent-failures, types, comments, gate, adversarial)
  • If no subcommand: check for uncommitted changes → default to changes, else show usage
  • Companion name: codex, gemini, or claude (optional, resolved from registry defaults)
  • --model MODEL → override default model
  • --base BRANCH → diff against branch (for changes/pr)
  • --pr NUMBER → GitHub PR mode (for pr subcommand)
  • --context FILE → attach context files (for solve)
  • --type PRP|PRD|RFC|DESIGN → doc type override (for doc)
  • --issue NUMBER → GitHub issue (for status)
  • --timeout SECS → override default timeout
  • --all → dispatch to all installed companions in parallel
  • --exclude-self → exclude claude from --all runs
  • --quick → code review only (for changes: skip silent-failures/types/comments checks)

What ships with it

9 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.
