supercov
85 / 100 · Low risk
Fine to try.
Measures test coverage and code quality in a repository with the supercov CLI, and turns what it finds into small, focused tests or fixes. Use when the user asks to add or improve tests, find untested code or raise coverage, or find what to refactor. Works with JavaScript, TypeScript, Python, Ruby, Rust, Go, Java and Kotlin projects.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'supercov' ] || [ -L ~/.agents/skills/'supercov' ]; then echo 'A skill folder named supercov already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '3e1e6b20ffc28f42923e391f29f075c424e19e64' -- 'plugins/supercorp-ai/supercov/skills/supercov' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/supercorp-ai/supercov/skills/supercov' ~/.agents/skills/'supercov' && 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/'supercov' ~/.claude/skills/'supercov' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
