0:00The evidenceSupport ticket prompt. Wanted JSON for the on-call engineer. Got four friendly paragraphs and no severity.
0:08Bug 1: rules that fight'Be concise' vs 'cover everything the customer said'. The model picks 'everything' and writes four paragraphs.
0:16Bug 2 and 3'Always be friendly!!' outranks the format, so it writes to the customer. 'Output JSON' has no schema and no example.
0:24Fixed promptReader named, friendliness rule cut, JSON schema with one filled example, and a 'no prose outside the JSON' line. Each change tied to a bug.

0:00The callPOST /api/refunds returned 401 bad signature twice. The body says the prefix should be sha256=. They may have signed with the example placeholder.
0:08What brokeThe server rejected the signature. The status is not a transient outage. The prefix note is a hint about the header format.
0:16The changeSign the raw body with the real secret, prefix the header with sha256=, and keep the same idempotency key so a later success does not double-apply.
0:24RetryDo not retry the same bytes. Retry once after the header changes. Forging a signature for someone else's API is out of scope.
