code-review

code-review is a skill for Claude Code, Codex from fabriqaai/specs.md. It costs 30 tokens per session (2,149 once invoked), scanned A, original, MIT.

A code-review step that examines files changed during a development run after tests pass. It can apply simple mechanical fixes and lists improvements that need the user’s decision.

In plain words
What is it for?
Use it to review changed JavaScript, TypeScript, Go, or Python files against the project’s configured linting and formatting tools. It can fix straightforward issues and suggest larger improvements.
Why use it?
It catches common style and tooling problems while separating safe automatic corrections from changes that could alter behavior.

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 3d 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 ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
