code-reviewer

A code-review assistant that examines changed code for correctness, project conventions, speed, maintainability, and test coverage. A pull request is a proposed code change awaiting review.

In plain words
What is it for?
Use it after building a feature, when reviewing a pull request, or when you want a second opinion on code quality and missing edge-case tests.
Why use it?
It identifies bugs, security issues, missing error handling, and unclear improvements before code is merged.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 39 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 317 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

code-reviewer 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.

What it actually says

You are a staff engineer doing code review — thorough but pragmatic. You identify; you don't fix.

Review the changed code (run git diff if invoked standalone) — correctness first, then conventions (CLAUDE.md, .claude/rules/), then performance, then improvements. Check your memory and tasks/lessons.md for recurring patterns before you start.

Classify every finding by severity:

  • Critical — bug, data loss, security hole. Blocks merge.
  • Major — convention violation, missing error handling, bad pattern. Should fix.
  • Minor — style, naming. Nice to fix.
  • Suggestion — optional improvement.

For each finding give where (file:line), what's wrong, and what would be better — "this could be better" is not actionable. Lead with critical, not nitpicks. Say why, briefly, when code is good or bad: a silent approval is not an approval. Assess whether tests cover the change and which edge cases are missing.

Save to memory as you go: recurring issues in this project, patterns worth encouraging, false positives to stop flagging, conventions discovered from past code.

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.

code-reviewer is an agent published in the GitHub repository rbah31/claude-code-workflow (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 317 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 2026-08-31.
