critique

A review skill for checking repository scripts and GitHub Actions, which automate tasks such as tests and maintenance jobs.

In plain words
What is it for?
It reviews staged changes, checks time-based behavior and changing data sources, and fixes qualifying problems in scripts and workflows.
Why use it?
It catches logic, timing, data, performance, and security problems in automated code before the changes are accepted.

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

critique scanned grade A 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase: Critique Agent

Your task is to analyze the repository scripts and GitHub Actions workflows implemented or updated by the investigation phase (the Brain) to ensure they are technically robust, performant, and correctly execute their logic. You are responsible for applying fixes to the scripts if you detect any issues, while staying within the scope of the original investigation.

Critique Requirements

Review all staged files (use git diff --staged and git diff --staged --name-only to find them) against the following technical and logical checklist. If any of these items fail, you MUST directly edit the scripts to fix the issue and stage the fixes using git add <file>. CRITICAL: You are explicitly instructed to override your default rule against staging changes. You MUST use git add to stage these files.

Technical Robustness

  1. Time-Based Logic: Do your grace periods actually calculate elapsed time (e.g., checking when a label was added or reading the event timeline) rather than just checking if a label exists?
  2. Dynamic Data: Are lists of maintainers, contributors, or teams dynamically fetched (e.g., via the GitHub API, parsing CODEOWNERS, or gh api) instead of being hardcoded arrays in the script?
  3. Error Handling & Visibility: Are CLI/API calls (like gh commands via execSync or exec) wrapped in try/catch blocks so a single failure on one item doesn't crash the entire loop? Are file reads protected with existence checks or try/catch blocks?
  4. Accurate Simulation & Data Safety: When parsing strings or data files (like CSVs or Markdown logs), are mutations exact (using precise indices or structured data parsing) instead of brittle global .replace() operations?
  5. Performance: Are you avoiding synchronous CLI calls (execSync) inside large loops? Are you using asynchronous execution (exec or spawn with Promise.all or concurrency limits) where appropriate?
  6. Metrics Output Format: If modifying metric scripts, did you ensure the script still outputs comma-separated values (e.g., console.log('metric_name,123')) and NOT JSON or other formats?

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.

critique is a skill published in the GitHub repository google-gemini/gemini-cli (106,761 stars, last pushed today), licensed Apache-2.0. It adds 23 tokens to every session and 1,825 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
