Empirically validates a software metric before trusting or optimizing it — point it at any candidate metric (a command that takes a path and prints one number) plus a corpus, and it runs experiments that try to falsify each property a good metric must have. Checks determinism (same input, same number across runs and hash seeds), invariance to cosmetic edits (also an anti-gaming probe), monotonicity under construct-increasing edits, discrimination, robustness on edge inputs, near-linear tractabi…

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/'metric-validation-harness' ] || [ -L ~/.agents/skills/'metric-validation-harness' ]; then echo 'A skill folder named metric-validation-harness already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/pproenca/dot-skills' "$d" && git -C "$d" checkout --quiet 'cf93c57cac89d6fc3e4194686000411567f5caf3' -- 'skills/.experimental/metric-validation-harness' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/.experimental/metric-validation-harness' ~/.agents/skills/'metric-validation-harness' && 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/'metric-validation-harness' ~/.claude/skills/'metric-validation-harness' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
