Phase 1 of the auto-improvement loop — how the app designs and calibrates the ruler (the trustworthy metric) BEFORE any optimization; calibration itself is backend code, read its result with get_ruler. Covers a low-variance primary metric, frozen anchors, a calibrated noise band, guardrails, reward-hack guards, and a mandatory canary that must clear the band or the ruler is rejected.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'metric-design' ] || [ -L ~/.agents/skills/'metric-design' ]; then echo 'A skill folder named metric-design already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/kirodotdev/KiroCrew' "$d" && git -C "$d" checkout --quiet 'f2c5c50d602f1e6c2059a407b3a0c6fca6db44da' -- 'src/kiro_crew/apps/builtins/auto_improvement/skills/metric-design' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/kiro_crew/apps/builtins/auto_improvement/skills/metric-design' ~/.agents/skills/'metric-design' && 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-design' ~/.claude/skills/'metric-design' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
