FIG. N.21 — A spec sheet, signed before build
A spec sheet is one page. It lists what an agent reads, what it writes, which tools it may use and where it must stop.
01 — Plain language only
If the operations lead can’t read it in two minutes, it’s not finished. Jargon hides decisions.
02 — Limits are features
The most important line on the sheet is the limit: the amount, the confidence score or the customer type where the agent hands over.
03 — Signed, then built
Nothing is built until the sheet is signed. It becomes the test suite, the runbook and the audit trail.
