review

A structured review workflow for assessing code changes, pull requests, or plans against the project's written principles. The review reports findings but does not change the work.

In plain words
What is it for?
Use it to review code, pull requests, or implementation plans, with review depth adjusted to the size of the change.
Why use it?
It gives reviews a consistent basis for judging quality and helps focus attention on the most important issues.

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 2d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review

Thorough review grounded in project principles. Do NOT make changes — the review is the deliverable.

Use Tasks to track progress. Create a task for each step below (TaskCreate), mark each in_progress when starting and completed when done (TaskUpdate). Check TaskList after each step.

Step 1 — Load Principles

Read brain/principles.md. Follow every [[wikilink]] and read each linked principle file. These principles govern review judgments — refer back to them when evaluating issues.

Do NOT skip this. Do NOT use memorized principle content — always read fresh.

Step 2 — Determine Scope

Infer what to review from context — the user's message, recent diffs, or referenced plans/PRs. If genuinely ambiguous (nothing to infer), ask.

Auto-detect review mode from change size:

  • BIG CHANGE (50+ lines changed, 3+ files, or new architecture) — all sections, at most 4 top issues per section
  • SMALL CHANGE (under those thresholds) — one issue per section

Step 3 — Gather Context

For SMALL CHANGE reviews, read files directly in the main context — delegation overhead exceeds the cost of reading a few files.

For BIG CHANGE reviews, delegate exploration to subagents via the Task tool.

Spawn exploration agents (subagent_type: Explore) to:

  • Read the code or plan under review
  • Identify dependencies, callers, and downstream effects
  • Map relevant types, tests, and infrastructure

Run multiple agents in parallel when investigating independent areas.

Step 4 — Gather Domain Skills

Check installed skills (.agents/skills/, .claude/skills/) for any that match the review's domain.

Invoke matched skills now — read their output and use domain guidance to inform your review.

For domains not covered by installed skills, use find-skills to search for a relevant skill.

Step 5 — Assessment Pipeline

Work through all sections in order. For each section, check against loaded principles.

1. Scope Check

If the review targets work against a plan phase:

  • Read the plan phase that was assigned.
  • Run git diff --stat and git log --oneline for the relevant commits.
  • Flag files changed outside the plan phase's stated scope as scope violations.

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 poteto/brainmaxxing (273 stars, last pushed 6mo ago), licensed MIT. It adds 46 tokens to every session and 1,186 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 2026-08-30.
