funnel-build
When to use. When the user asks for an end-to-end acquisition funnel — traffic source → landing page → email capture → nurture → offer → conversion — and needs the channel-level structure that ties stages together.
Procedure (stub). Diagnose the See / Think / Do stage map first (route to channel-strategy). For each stage, pick the channel that feeds it and the next-step asset that catches the audience and moves them one rung. Common architecture: See-stage paid social → Think-stage lead magnet landing page → Care-stage welcome sequence → Do-stage sales sequence. Spec the bridge between each stage explicitly: what triggers the next step, what creative the next stage needs, and what measurement validates the bridge worked. Coordinate with Copy for landing-page words and email bodies; with Forge for the offer at the bottom; with Lens for the tracking. The funnel diagram is the deliverable; do not build inside any one platform's funnel-builder tool without first proving the architecture works on whiteboard logic.
Status. Default tier: user-toggle. Full procedure deferred to Phase 2. Until then, the channel-strategy skill handles cross-channel decisions.
