code-review-assistant is a skill for Claude Code, Codex from ValorVie/custom-skills. It costs 64 tokens per session (1,617 once invoked), scanned A, original, MIT.

A checklist for reviewing code changes and pull requests. A pull request is a proposed change that teammates inspect before adding it to the shared codebase.

In plain words
What is it for?
Use it for pull-request reviews and pre-commit checks, with labels showing which findings must be fixed and which are optional.
Why use it?
It reduces the chance of missing problems with behavior, design, tests, security, performance, or documentation before merging.

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-assistant 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.

For AI assistants, use the YAML format file for reduced token usage:

  • Base standard: ai/standards/code-review.ai.yaml

Example Review Comments

❗ BLOCKING: Potential SQL injection vulnerability here.
Please use parameterized queries instead of string concatenation.

⚠️ IMPORTANT: This method is doing too much (120 lines).
Consider extracting validation logic to a separate method.

💡 SUGGESTION: Consider using a Map here instead of an array for O(1) lookup.

❓ QUESTION: Why are we using setTimeout here instead of async/await?

📝 NOTE: This is a clever solution! Nice use of reduce here.

What ships with it

2 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.
