code-review

code-review is a skill for Claude Code from euxx/claude-skills-for-copilot. It costs 41 tokens per session (982 once invoked), scanned A, original, MIT.

A multi-agent review of local code changes, files, or directories. It checks for bugs, security issues, and violations of project guidance files.

In plain words
What is it for?
Reviewing a change, file, or directory for correctness, security, project-rule violations, and relevant issues in the code’s history.
Why use it?
It provides several independent checks, making it easier to spot important problems before code is merged or shipped.

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 8d 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.

Code Review

Provide a code review for the given code changes (e.g. local changes, a file, or a directory).

Steps

Make a todo list first, then follow these steps precisely:

1. Gather context

  • Use a sub-agent to list file paths of relevant conventions files in this priority order: AGENTS.md, then CLAUDE.md, then GEMINI.md. Include the root file (if one exists), plus files in directories whose files were changed.
  • Use a sub-agent to scan the code changes and return a summary of the change.

2. Parallel review

Launch 5 parallel sub-agents to independently review the change. Each agent returns a list of issues with the reason flagged (e.g. conventions-file adherence, bug, historical context):

  • Agent 1 — Conventions-file compliance: Audit changes against AGENTS.md or similar conventions files (CLAUDE.md, GEMINI.md), using priority order AGENTS.md -> CLAUDE.md -> GEMINI.md. Note that these files are guidance for AI while writing code; not all instructions apply during code review.
  • Agent 2 — Bug scan: Shallow scan for obvious bugs, focusing only on the changed lines. Prioritize large bugs; ignore nitpicks and likely false positives.
  • Agent 3 — Git history: Read git blame and history of modified code to identify bugs in light of historical context.
  • Agent 4 — Code comments: Read comments in modified files and verify the changes comply with any guidance in those comments.
  • Agent 5 — Security & quality: Look for security issues and code quality problems that would directly impact functionality.

3. Confidence scoring

For each issue found in step 2, launch a parallel sub-agent to score it from 0–100 (give this rubric to each agent verbatim):

  • 0 — Not confident at all. False positive that doesn't stand up to light scrutiny, or a pre-existing issue.
  • 25 — Somewhat confident. Might be real, but unverified. If stylistic, not explicitly called out in the applicable conventions file.
  • 50 — Moderately confident. Verified as real, but may be a nitpick or rare in practice. Not very important relative to the rest of the change.
  • 75 — Highly confident. Double-checked; very likely a real issue that will be hit in practice. Important and directly impacts functionality, or directly mentioned in the applicable conventions file.
  • 100 — Absolutely certain. Confirmed real issue that will happen frequently. Evidence directly confirms 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.
