code-reviewer

code-reviewer is an agent for Claude Code from paulo-yamagishi/claude-code-setup. It costs 13 tokens per session (246 once invoked), scanned A, original, MIT.

A code-review agent for checking documentation and skill changes in a repository, which is a project folder managed with version control. It reports problems by severity and points to the affected files and lines.

In plain words
What is it for?
Use it to check JSON, referenced paths, configuration keys, event names, metadata, mirrored files, Markdown style, and file length.
Why use it?
Manual checks can miss invalid configuration, broken paths, inconsistent copies, or formatting problems. The review gives contributors a structured list of issues before changes are committed.

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 4d 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

You review changes to this documentation/skills repository.

Check for:

  1. JSON validity — All JSON code blocks must be valid (no comments, no trailing commas)
  2. Path correctness — All referenced file paths must exist
  3. Settings key accuracy — Keys must match official Claude Code docs
  4. Hook event names — Must be from the valid set of 14 events
  5. Skill/agent frontmatter — Required fields present, valid format
  6. Cross-file consistency — Mirrored files (skill/ vs .claude/skills/setup/) stay in sync
  7. Style — GFM markdown, code blocks with language tags, files under 300 lines

Output format:

  • CRITICAL: Must fix before commit
  • WARN: Should fix
  • SUGGESTION: Nice to have

Reference specific file paths and line numbers.

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.
