Anthropic: Extend Claude with Skills (official docs)
What it is
Official documentation for Agent Skills, a `SKILL.md` file that packages a checklist or multi-step procedure so the assistant loads it only when relevant. The trigger it names is exactly the founder pain point: you keep pasting the same instructions into chat.
Why we picked it
Primary source, no vendor spin, and it converts Module 4's "document your expertise" lesson into a file format the AI actually executes.
How you might use it
If marketing is your bottleneck, this is the kind of resource the Get More Customers workflow uses. Start small: one campaign, one week. Judge it by replies and booked calls, not by impressions.
