Eight tasks: the SDK and its optional key, the Zod shape the model must answer in, the prompt, the call, writing a draft back, the worker that drives it, the wiring, and one real photograph to see whether any of it writes something worth reading.
The prompt is the correctness surface and gets its own task with its own tests. On one-of-a-kind stock an invented "1930s hand-thrown stoneware" is not a cosmetic error but a false claim on a storefront, and nothing downstream can tell an invented detail from an observed one — the only place that distinction can be enforced is in the instruction, so the tests assert it is there.
The other governing rule is that a submission is the only irreplaceable thing in the pipeline. The photos are often the only copy of an item no longer in the sender's hands, so a missing key, a failed call, a malformed answer and three exhausted retries all end the same way: the item keeps its photos and waits undrafted. Nothing in the worker deletes anything, and an absent key does not spend an attempt.
Only the suggested price reaches the item, per #220, with price_source recording that a model rather than a person chose it. The name and description stay on the draft row until the review queue in #225 exists.
The monthly spend ceiling is deliberately left out. Task 8 measures what a real call costs first, because a budget set from a guessed number is one nobody trusts.
Every test stubs the Anthropic client. A test that reaches the real API is a defect in the test.
