97 / 100 · Low risk

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

By ccusage/ccusage (GitHub) · coding · 19,435 stars · scanned at commit 83d3f20

Verifies ccusage terminal output in a real cmux pane. Use when changing responsive tables, column widths, progress bars, spinners, or colors, or when a long-running command's output must be captured beyond the visible viewport.

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/'cmux-debug' ] || [ -L ~/.agents/skills/'cmux-debug' ]; then echo 'A skill folder named cmux-debug already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/ccusage/ccusage' "$d" && git -C "$d" checkout --quiet '83d3f209a86e8b6f1e86eaf93f10568a262fd4e4' -- '.agents/skills/cmux-debug' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/cmux-debug' ~/.agents/skills/'cmux-debug' && 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/'cmux-debug' ~/.claude/skills/'cmux-debug' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
