What is code-reviewer?

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.

Use it to check JSON, referenced paths, configuration keys, event names, metadata, mirrored files, Markdown style, and file length.

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.

code-reviewer — Agent for Claude Code by paulo-yamagishi

Install

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.

Clone the repo

git clone --depth 1 https://github.com/paulo-yamagishi/claude-code-setup

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00013	$0.00246
Opus 5.5	$0.00005	$0.00098
Sonnet 5.5	$0.00003	$0.00049
Haiku 4.5	$0.00001	$0.00025

Measured 2mo ago against content hash 101d33bad094, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

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 2mo 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:

JSON validity — All JSON code blocks must be valid (no comments, no trailing commas)
Path correctness — All referenced file paths must exist
Settings key accuracy — Keys must match official Claude Code docs
Hook event names — Must be from the valid set of 14 events
Skill/agent frontmatter — Required fields present, valid format
Cross-file consistency — Mirrored files (skill/ vs .claude/skills/setup/) stay in sync
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.
