What problem does it solve? Teams routinely adopt metrics that look rigorous but fail in practice: vanity numbers that inform no decision, key results nobody can verify, outputs disguised as outcomes, and targets that invite gaming without guardrails. This Skill audits any metric set against seven validity principles and returns severity-rated findings with concrete rewrites instead of vague encouragement. ## Core Features & Use Cases - Seven-Principle Validity Framework: Tests every metric for outcome-vs-output orientation, falsifiability, vanity exposure, objective quality, causal connection to value, gaming exposure with guardrails, and leading/lagging balance. - Severity-Rated Output: Classifies findings as Critical, Major, Minor, or Cosmetic based on decision damage, and always ends with a prioritized top-3 fix list including suggested rewrites. - Use Case: A product manager drafts quarterly OKRs in a strategy doc. Run this audit to catch that "Ship 12 features" is an output, "Improve satisfaction" is unfalsifiable, and the session-duration target has no quality guardrail — then get concrete rewritten key results. ## Quick Start Ask the assistant to audit the OKRs or KPIs in your current document for validity and list the top three fixes with rewrites.
