Fed both baselines the same 'shipped GitHub-to-post automation' update: the unguided baseline used exactly the banned phrases the skill's own voice rules forbid ('game-changing', 'excited to announce', an emoji-laden CTA), while the skill-guided version led with a real number (20 min to under 2 min) and one takeaway per the 5-question build-in-public structure.

What Founder Content System does

A prompt framework (no scripts) that runs content through Research -> Extract -> Adapt -> Write, plus a dedicated build-in-public workflow (5-question story extraction) and a repurposing framework (one piece to 7-10 derivatives). Triggers on 'write a post', 'turn this into posts', 'thread', 'build in public', 'ship update', 'content calendar'.
