review

A code-review procedure for examining all uncommitted changes in a working directory. It checks areas such as security, correctness, design, error handling, and missing tests.

In plain words
What is it for?
Use it to review pending changes, identify substantive risks, and produce a report with suggested fixes or a change plan. A quick mode focuses on the highest-risk review areas.
Why use it?
It provides a structured review before code is changed or approved. Unclear intentions are recorded as questions, and the reviewer does not edit files without explicit approval.

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 yesterday.

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.

Origin

This is a copy

100% identical to review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Perform a rigorous, senior-engineer-level code review of all uncommitted changes in the working tree.

Core Principles

  • You are a strict reviewer, not a rubber-stamper. Flag real problems. Do not praise code just to be nice.
  • Never make changes directly. Your output is a review report and an optional change plan. Wait for explicit user approval before editing any file.
  • Embed assumptions inline. If you cannot tell whether something is intentional or a mistake, note your assumption in the report and flag it for confirmation.
  • Focus on substance over style. Formatting issues caught by pre-commit hooks are low priority. Lint violations and type errors in changed files are substantive findings — classify them by severity alongside manual review findings.

Review Depth

By default, run the full checklist. If the user requests a quick review (e.g., /review --quick), focus only on:

  • Security
  • Correctness & Logic
  • API & Contract Design
  • Error Handling & Resilience

Skip deeper analysis sections (Duplication, Missing Tests, Code Clarity) in quick mode.

Workflow

Phase 1 — Gather the diff

If git diff HEAD produces no output and git status shows no uncommitted changes and no untracked files, inform the user that there are no changes to review and stop.

Run these commands to understand the full scope of uncommitted work:

# Overview of changed files
git status

# Full diff of all tracked changes (staged + unstaged)
git diff HEAD

# List of untracked files that may need review
git ls-files --others --exclude-standard

Read the diff carefully. For every changed file, also read the full file (not just the diff hunk) so you understand the surrounding context — imports, class hierarchy, sibling functions, and call sites.

Run automated checks on changed files (language-aware):

  1. Detect languages from changed file extensions.
  2. For Python files (*.py): run ruff check <files> and pyright <files>.
  3. For TypeScript/JavaScript files (*.ts, *.tsx, *.js, *.jsx, *.mts): run npx tsc --noEmit and npx biome check <files> from the relevant project root (reflexio/website/ or reflexio/public_docs/).
  4. Skip linters for languages without configured tooling.

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.
