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

Agentically test a specific feature end-to-end in the running Carbon dev server — analyze the branch diff (or a given feature/issue), build a test plan, drive the app with agent-browser, and cache successful playbooks to .ai/playbooks/ for reuse. Use to verify a feature or fix actually works in the browser ("test this", "verify in the browser", after /execute or /fix for user-facing changes). Builds on /auth and /error. For a broad does-everything-load sweep use /smoke-test.

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/'test' ] || [ -L ~/.agents/skills/'test' ]; then echo 'A skill folder named test 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 "$d" checkout --quiet '23320e4132e2b978e186521fbfb4225017a18d1f' -- '.claude/skills/test' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/test' ~/.agents/skills/'test' && 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/'test' ~/.claude/skills/'test' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
