code-reviewer

code-reviewer is a skill for Claude Code, Codex from bugrabilge/bilge-development-kit. It costs 14 tokens per session (2,467 once invoked), scanned A, original, MIT.

A guide for thorough code reviews using modern code-analysis and AI-assisted review practices. Code review is the process of examining changes before they are accepted.

In plain words
What is it for?
Use it for code-review workflows, pull-request assessments, static analysis, and production-quality checks.
Why use it?
It helps identify bugs, security vulnerabilities, performance issues, maintainability problems, and risks that could cause production incidents.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/ai_review.py \.

Good fit Use it for code-review workflows, pull-request assessments, static analysis, and production-quality checks.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 5d 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 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.
