67 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

By MadAppGang/claude-code (GitHub) · coding · 288 stars · scanned at commit 6097ad4

On-demand test coverage analysis. Use when identifying untested code, finding test gaps, measuring coverage metrics, or improving test quality. Trigger keywords - "test coverage", "coverage report", "untested code", "test gaps", "missing tests", "coverage metrics".

Works with any agent that supports SKILL.md skills.

Safer alternatives

Low-risk skills in the same category (coding) that look related. Check that one does what you need.

Install

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

if [ -e ~/.agents/skills/'test-coverage' ] || [ -L ~/.agents/skills/'test-coverage' ]; then echo 'A skill folder named test-coverage already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadAppGang/claude-code' "$d" && git -C "$d" checkout --quiet '6097ad4643f23b7645a9c99c329887b623b32e57' -- 'plugins/dev/skills/test-coverage' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/dev/skills/test-coverage' ~/.agents/skills/'test-coverage' && 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-coverage' ~/.claude/skills/'test-coverage' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
