review

review is a command for Claude Code from isaacsight/kernel. It costs 0 tokens per session (146 once invoked), scanned A, original, MIT.

A code-review command that examines the files changed in the current project and reports quality, correctness, security, and performance issues.

In plain words
What is it for?
Use it to check changed code for type problems, missing error handling, broken imports, design-system violations, exposed secrets, and inefficient rendering.
Why use it?
It gives you a structured review of recent changes, including specific file and line references, before they are merged or released.

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.

What it actually says

Review the current codebase changes for quality and correctness.

Steps:

  1. Run git diff --stat to see what files changed
  2. For each changed file, review the diff
  3. Check for:
    • Type safety issues
    • Missing error handling
    • Broken imports or circular dependencies
    • Design system violations (should use EB Garamond, ivory palette, Rubin aesthetic)
    • Security issues (exposed keys, unsanitized input)
    • Performance concerns (unnecessary re-renders, missing memoization)
  4. Provide a summary with specific line references
  5. Rate overall quality: 🟢 Ship it / 🟡 Minor fixes / 🔴 Needs rework

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 command published in the GitHub repository isaacsight/kernel (16 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 146 tokens. 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 2026-09-03.
