Verify a measurable-improvement claim against a baseline captured BEFORE the change. Two metric families (`performance`: wall time, memory, allocations, throughput, latency; `metrics`: complexity, coverage, coupling), each with a `baseline` phase at planning time and a `compare` phase after the change. Never claims improvement without a baseline (no baseline → honest 'cannot quantify'). Use when: 'is it faster', 'before/after', 'prove the improvement', 'did that actually speed it up', 'how much…

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/'measure' ] || [ -L ~/.agents/skills/'measure' ]; then echo 'A skill folder named measure already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '677e7988f432dacb5e2d4df2b124f96da8e8f9f3' -- 'plugins/verification/skills/measure' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/verification/skills/measure' ~/.agents/skills/'measure' && 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/'measure' ~/.claude/skills/'measure' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
