## What it does

This skill operates at the strategic top of the acquisition funnel. It specifies how new contacts discover the offer, designs lead magnets or incentives, and defines single versus double opt-in requirements. All subscriber growth rates and cost-per-opt-in targets carry an Estimated or User-provided tag.

Boundaries between tools stay clear. The skill avoids drafting email copy or designing sign-up forms directly. Instead of writing straight to `memory/consent/`, it posts proposed events to `memory/events/consent.ndjson` via `registry-events.py`, leaving the actual recording to `consent-registry`.

No API keys are mandatory because basic operation relies on pasted export data from an email platform or GA4 analytics. Choosing the legal jurisdiction matters immediately; without it, compliance requirements remain ambiguous.

# List Growth Designer

Plans how to grow an **owned** email list — acquisition channels, lead-magnet / incentive concepts, a compliant opt-in capture-flow spec, and referral-loop mechanics — and defines the growth metrics that gate whether it is working. It is the strategy layer at the top of the funnel: it decides *what* to offer and *how* subscribers enter, so that consent is captured cleanly (the upstream of the SEND-`S2` red line) and each new subscriber lands in a lifecycle (SEND-`N`). It does not build the signup page, write the confirmation email, or record the opt-in — it hands those to the owning skills.
