What we shipped with it

No notes yet.

We haven’t shipped with Anthropic APIyet. When we do, what we learned will land here — terse, dated, honest. The bar is “a real thing we built, including what didn’t work.”

Editorial cadence is bi-weekly. Pieces are mined from real shipping logs, not generated from vendor copy.
