Anthropic: Using Agent Skills with the API (Skills API now GA)
What it is
Agent Skills and the Skills API (`/v1/skills`) came out of beta on 10 September 2026, no beta header required. You upload a folder of instructions once, then name it in the requests that should use it (`container.skills`, with the code execution tool switched on) and Claude pulls in the detail when the task calls for it. That is Module 4's "document your expertise" lesson turned into a deployable artifact instead of a document nobody re-reads.
Why we picked it
GA status is the signal students need, this is now a stable foundation to build a business SOP library on, not a beta that will move under them. Pairs with entry 191.
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.
