Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Build a self-contained HTML review aid at .pr-review/{branch}.html that teaches a reviewer what a PR changes and why — problem, system context, before/after flow, focused diffs, verification evidence, takeaway. Use when asked to explain a PR, help reviewers understand a complex change, or produce a review page for a branch. Do not use it as a substitute for review itself (/self-review) or instead of a PR description.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'pr-explainer' ] || [ -L ~/.agents/skills/'pr-explainer' ]; then echo 'A skill folder named pr-explainer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/crbnos/carbon' "$d" && git -C "$d" checkout --quiet '23320e4132e2b978e186521fbfb4225017a18d1f' -- '.claude/skills/pr-explainer' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/pr-explainer' ~/.agents/skills/'pr-explainer' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'pr-explainer' ~/.claude/skills/'pr-explainer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
