code-review

code-review is a skill for Claude Code, Codex from andreaswasita/copilot-agents-dojo. It costs 13 tokens per session (1,034 once invoked), scanned A, original, MIT.

A guide for reviewing code changes, such as a branch diff or pull request. It examines the change from its purpose through its structure and individual lines, then groups findings by severity.

In plain words
What is it for?
Use it before merging changes, when auditing a pull request, or when checking the agent’s own implementation.
Why use it?
It turns a broad code check into clear, prioritized feedback about security, correctness, performance, or other risks without rewriting the author’s code.

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 1mo 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review Skill

Reviews diffs and PRs the way a senior engineer would: intent first, structure second, line-by-line third. Produces feedback grouped by severity (🔴 must / 🟡 should / 🟢 nit) with concrete suggestions. Does NOT rewrite the author's code — it directs, it does not replace.

When to Use

  • Reviewing a pull request, branch diff, or staged changes.
  • Auditing changes before merge.
  • Self-reviewing the agent's own output before presenting it.
  • Hunting for security, correctness, or performance regressions.
  • The user asks "does this look right?" about a code change.

Prerequisites

  • The view, grep, and glob Copilot tools to read code.
  • git available so diffs can be inspected (git diff main, git log).
  • Read access to the repository being reviewed.
  • For PR-scoped review: gh CLI authenticated to fetch PR metadata.

How to Run

1. Read the PR title, description, and linked issue.
2. List changed files (`git diff main --stat`) and assess scope.
3. Walk the diff with the `view` tool, file by file.
4. Apply the severity rubric below.
5. Emit a structured review block with concrete fixes.

Quick Reference

Phase Tool What to check
Intent PR description, linked issue Why does this change exist?
Scope git diff main --stat Files changed match stated intent
Correctness view on hot paths Logic, null/edge handling, off-by-one
Security grep for secrets, raw SQL, eval Injection, auth bypass, leaked secrets
Performance view on loops, queries N+1, unbounded allocations, missing indexes
Tests view on test files New paths actually covered

Procedure

Step 1: Understand Intent

Read the PR description, commit messages, and any linked issue. If intent is unclear, stop and ask the author — reviewing code whose purpose you don't understand wastes everyone's time.

Step 2: Structural Pass

Use git diff main --stat to size the change. Check:

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.
