Invokes when you're writing headlines, CTAs, ad copy, landing pages, or email copy. Reads your project context if available, then walks you through proven frameworks like PAS, AIDA, and BAB depending on what you're building. Includes headline formulas, platform-specific constraints for ads, and CTA best practices. The information gain angle is smart: it pushes you to differentiate from what competitors already say rather than restating generic promises. Outputs 2-3 headline variants, body structure, and A/B test suggestions. If you're writing long-form article bodies instead of marketing copy, it routes you to the article-content skill.
