Lead Magnet Builder — bait that matches the buyer

A lead magnet is not a gift, it is a filter. The right magnet solves one narrow, urgent slice of the exact problem the paid offer solves fully — so the people who grab it are the people who buy. A magnet that appeals to everyone grows the list and starves the pipeline.

Inputs

• The paid offer the magnet feeds, the audience, and any candidate ideas: $ARGUMENTS
• From marketing-brief.md if present: the offer, top pains and desired outcomes, the ICP, the language bank, and the banned-phrases list.

Do this

1. Generate 6–10 candidates (fold in any supplied). Each must sit on one of the brief's top pains and be a genuine first step of the paid journey — a checklist, template, teardown, calculator, swipe file, or short guide.
2. Score each 1–5 on four axes and show the table:
   • Pulls the ICP specifically — would someone who will never buy still want it? Then it scores low.
   • Consumable in under 15 minutes — magnets that ask for an evening never get opened.
   • Delivers a real win — something is genuinely solved by the last line, not teased.
   • Sets up the offer — finishing it makes the paid next step feel obvious.
3. Pick the winner and outline it: three title options (specific, outcome-named), the promise, the sections, and the built-in bridge — the magnet solves step one and makes step two visible.
4. Write the core content in full. The actual checklist, template, or guide — complete and usable, not a summary of what it would contain. Where the content needs data the brief lacks, flag the gap instead of inventing.
5. Write the giveaway copy: the opt-in page (headline, three bullets, CTA) and two social posts announcing it, phrased from the language bank.
6. Name delivery and follow-up: what the delivery email says (the magnet plus one consumption tip) and when the paid offer first appears — usually after the win lands, not before.

Output

The scoring table, the finished magnet ready to format, opt-in page copy, two promo posts, and the delivery note. Flag every place where thin data forced a placeholder.

Rules

• The magnet must be genuinely useful on its own. If it only works as an advert for the offer, it is a brochure wearing a bow.
• The title may lean on curiosity; the contents deliver exactly what the title promised.
• Specific beats broad. A 12-point pre-launch checklist beats an ultimate guide to marketing.
• Evidence over invention: no fabricated statistics or examples inside the magnet. Its credibility is the whole point.
• Ask for the minimum at opt-in — usually just the email address. Every extra form field costs more subscribers than it is worth.
