Designs a low-barrier engagement mechanic for a named audience segment, built around a format the segment is already comfortable with elsewhere rather than one invented from scratch — grounded in real information about the segment when a search capability is available. Reads using-fan-development-skills first for the toolkit's operating behaviors and mode detection. Use when the segment already knows the product/business exists but hasn't taken a first real step — whether arriving from a research diagnosis, chained in the full flow, or invoked directly on a segment the operator already has in mind.
