coverage-ratchet

95 / 100 · Low risk

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

Gate test coverage with a ratchet — a committed baseline that coverage may never drop below and only ever rises. Ships a coverage-gate script (xccov-based) plus an advisory CRAP report (complexity × uncovered). Use when agent-written code needs a deterministic "tests were actually written" check.

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/'coverage-ratchet' ] || [ -L ~/.agents/skills/'coverage-ratchet' ]; then echo 'A skill folder named coverage-ratchet already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/rshankras/claude-code-apple-skills' "$d" && git -C "$d" checkout --quiet 'f9589828e222113d49c7bff417c33038802856ff' -- 'skills/testing/coverage-ratchet' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/testing/coverage-ratchet' ~/.agents/skills/'coverage-ratchet' && 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/'coverage-ratchet' ~/.claude/skills/'coverage-ratchet' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
