pm-funnel-criticlisted

# PM funnel critic Runs a funnel-layer review on an activation or conversion experience. The existing skills cover adjacent layers: `pm-metrics-critic` catches metric-level failures (vanity metrics, gaming, segment masking); `pm-design-critic` catches surface-level failures (defaults, friction placement, choice architecture). This skill sits between them — at the layer where a sequence of metrics combines with a sequence of design moments into a funnel that either works or doesn't. The job is to name the binding stage, name the drop-off driver, and propose specific experiments that would close the largest gap, not the easiest one. ## When to use Use this when: - A PM shares an onboarding flow, a paywall design, a trial structure, or a growth dashboard - A team is debating which stage of the funnel to optimize next - A PM has activation or conversion numbers that "look fine" and wants to know whether they're top-decile or median - A team is choosing between Enterprise (sales-led) and PLG (product-led) conversion mechanics and wants the trade-off named - A team is preparing a growth-related PRD or strategy memo and wants the funnel logic stress-tested before circulation Don't use this when: - The strategy isn't framed yet — route to `pm-decision-coach` or `decision-making/problem-framing.md` first - The artifact is purely metric-layer (a KPI debate with no funnel structure) — use `pm-metrics-critic` - The artifact is purely surface-layer (an onboarding mockup with no funne
