Skills (7)

• ab-test-design

  Use before running any experiment that will inform a product decision. All six elements — hypothesis, metric, sample size, duration, stopping rule, and decision rule — must be defined before the test starts. Blocks "we'll stop when we see something" completions.

• ai-feature-validation

  Use before any AI feature is approved for build. Covers four AI-specific risks that standard PRD review misses: hallucination UX, trust calibration, scope creep, and reversibility. Blocks "we validated it like any other feature" completions.

• feature-scoping

  Use before any engineering estimate is made. Requires a written scope before an estimate, and a written estimate before a commit. Blocks "we'll scope as we go" and "just give me a rough number" completions.

• metric-definition

  Use before writing any implementation code for a new feature. North star metric, guardrail metrics, and diagnostic metrics must be defined — with baselines — before the build begins. Blocks "we'll figure out the metrics from the data" completions.

• mvp-scope-validator

  Use before writing a PRD for a new product or feature. Extracts the core hypothesis and reduces scope to the minimum needed to test it. Blocks feature lists that bundle multiple unvalidated assumptions.

• prd-quality-gate

  Use before committing scope, estimate, or engineering time to any feature. Requires user problem, success metric, scope boundary, and anti-goals defined before any estimate is made. Blocks "we'll define success once we see the data" completions.

• user-research-synthesis

  Use after conducting user research and before making product decisions from it. Requires every insight to map to a decision. Blocks "users said X" reports that produce no actionable direction.
