Turn Claude Hopkins’ Scientific Advertising into 20 executable skills. No generic copywriting advice — every rule traces to a specific Hopkins quote from a specific chapter.

Skills cover: copy audits (3-tier PASS/NEAR-PASS/FAIL scoring), headline workshops, offer design, appeal selection, campaign diagnostics, A/B testing, cost-per-customer calculation, image briefs, direct-mail letters, long-copy ads, brand persona, pricing strategy, and a complete 30-day launch plan.

Start with Skill #18 (Plugin Onboarding) — describe your business, get routed to the right skills in the right order.

All 20 skills were manually tested on a real business before writing. Each has 5 eval cases including a false-positive resistance test. Strong copy does not get penalized.

Best for: business owners running or planning paid campaigns; marketers applying direct-response principles; agencies auditing client campaigns.
