github-code-review

github-code-review is a skill for Claude Code, Codex from itgoyo/hermes-skills. It costs 45 tokens per session (3,697 once invoked), scanned C, original, no licence file.

A code review tool for examining changes in a Git repository and GitHub pull requests. A pull request is a proposed code change that others review before it is added to the main project.

In plain words
What is it for?
Use it to inspect Git differences, review changes before pushing, and comment inline on pull requests.
Why use it?
It can spot problems before code is pushed or merged and lets you leave comments directly beside the relevant lines. This keeps feedback tied to the exact change being discussed.

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 C, and why

github-code-review scanned grade C with 2 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

description: Review code changes by analyzing git diffs, leaving inline comments on PRs, and performing thorough pre-push review. Works with gh CLI or falls back to git + GitHub REST API via curl.

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.
