A baseline pass on the mini-task produced a headline and CTA ('Manage Your Projects Better' / 'Get Started') that land exactly on the two anti-patterns the skill's own Weak CTAs / vague-language rules tell you to avoid -- the skill-guided version replaced both with an outcome-specific headline and a CTA naming what the user actually gets.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Copywriting does

Writes and rewrites marketing page copy (homepage, landing, pricing, feature, about pages) using headline formulas, a benefits-over-features / specificity-over-vagueness rule set, and an explicit weak-CTA ('Submit,' 'Learn More,' 'Get Started') vs strong-CTA list. Triggers on headline/CTA/value-prop/hero-copy and 'this copy is weak' requests; defers to copy-editing for line-editing existing copy and to emails/popups for those specific formats.
