code-review

A guide for reviewing a pull request, which is a proposed set of code changes, for quality, security, and compliance with project standards. It can trace code across files and involve a security review for sensitive areas.

In plain words
What is it for?
Use it to inspect pull requests, check how code fits the surrounding application, and review changes involving authentication, encryption, or secrets.
Why use it?
It provides a consistent review process for finding problems before 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

code-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 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.

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

/code-review — Code Review

Review a pull request for quality, security, and adherence to standards.

This skill performs semantic code navigation — finding definitions, walking references, tracing handlers across modules. With LSP enabled (ENABLE_LSP_TOOL=1 + per-language plugin per docs/getting-started.md), queries are ~3-15× cheaper in token cost than grep + Read. Without LSP, the skill falls back to grep + Read transparently — no new failure mode, just optional speed.

Per-language LSP plugins live in Claude Code's marketplace. Install once; the skill detects the active language and dispatches automatically.

Activated agent + role

When /code-review runs:

  1. Primary reviewer: the Code Reviewer agent (Rex) at .claude/agents/code-reviewer.md — runs on every commit, owns the automated first-pass review.
  2. Human approval gate: the Tech Lead — activates to sign off on architecture, design patterns, and team conventions that Rex can't judge from code alone.
  3. Conditional Security Auditor: if the diff touches **/auth/**, **/crypto/**, **/secrets/**, .env*, or similar, the Security Auditor also activates and must sign off before merge. Consider chaining /security-review for the deeper pass.
  4. Conditional UI Designer: if the diff touches visible UI, the UI Designer activates for design review.

See .claude/rules/role-triggers.md for the full activation protocol.

Process

0. Write the active-reviewer marker (REQUIRED — me2resh/apexyard#843)

Before spawning the Code Reviewer agent (Rex), write the active-reviewer session marker. It records that this review pass is the sanctioned one, and suppresses warn-review-marker-write.sh's advisory warning on Rex's *-rex.approved write (that hook warns and never blocks since #1026 — AgDR-0111).

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-review is a skill published in the GitHub repository me2resh/apexyard (497 stars, last pushed 3d ago), licensed MIT. It adds 25 tokens to every session and 1,325 once invoked, about $0.0001 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.
