End-of-Article CTA Designer

Designing an end-of-article CTA is a function of three inputs: the objective (what action), the audience (who reads it, in what relationship to the author), and the context (independent writing, newsletter, brand publication). Get those three right and the copy + form follow almost mechanically. Skip them and you get the universal failure mode: a generic "Subscribe for more" or "Learn More" that converts at the noise floor.

This skill runs a tight interview to capture those three inputs, then prescribes a CTA: copy (what it says), form (how it looks and sits on the page), mechanism (whether to use urgency, scarcity, curiosity, reciprocity, social proof, or none), an A/B test plan, and an accessibility check.

Workflow

Run the four steps below in order. Do not skip the interview. The user may have given partial context already; pull what's available from the conversation, then ask only for the missing pieces.

Step 1 — Interview

Use the ask_user_input_v0 tool. Ask one question at a time. Do not stack questions in prose. Each question must have 2-4 tappable options. Fall back to free text only if the answer genuinely cannot be enumerated.

Ask these in order, skipping any already answered:

Q1. Article context. Options: Personal / independent blog or essay · Newsletter / paid publication (Substack, beehiiv, Ghost, etc.) · Brand / company / content-marketing blog · Other (free text)
