Highlights
- Ben Sabic, 21 September 2026. Choice picks an option, Score rates ordered evidence, and Boolean estimates that a statement is true.
- The table maps form routing and tool-call review to Choice, ticket priority to Score, and moderation to Boolean.
- Document categorization is Choice. Checking a generated answer is Boolean or Score.
- The post says to keep fixed business rules in code and let the app decide what happens after the answer.
Watch out
A product guide. It does not publish accuracy, latency, or cost for these seven jobs.
Questions about this entry
Short answers drawn from the linked project or page.
No. It is a pattern catalog: a table mapping each job to Choice, Score, or Boolean, plus a reference implementation of the form router. No accuracy, latency, or cost figure appears for any of the seven, so treat the claims about tool-call review and response scoring as unmeasured.
Not blindly. The AI SDK form router accepts Jev's selected destination only when its confidence clears a threshold you configure. An uncertain result or a failed evaluation hands the submission to a fallback model for an independent decision, so a low-confidence answer routes to more scrutiny rather than a wrong inbox.
The guide says don't. It separates ticket ownership from ticket priority and tells you to keep contractual response deadlines in code. Score interprets the reported impact against descriptions you write, such as cosmetic versus blocked work; it does not establish what a customer is entitled to.
Because the decision is deliberately binary in eve's automatic tool-approval workflow. Jev reviews the proposed tool name and arguments and picks clear or caution; clear calls run without asking, caution calls pause for a person, and a failed review also blocks the call.
The guide's table maps form routing and tool-call review to Choice, ticket priority to Score, and moderation to Boolean. Document categorization is Choice, and checking a generated answer is Boolean or Score.
Routing forms, prioritizing tickets, reviewing tool calls, picking a model, categorizing documents, moderation, and checking a generated answer. The post is by Ben Sabic and dated 21 September 2026.
The guide says to keep fixed business rules in code and let the application decide what happens after the answer. Jev returns the typed choice, score or probability; the routing, thresholds and side effects belong to your code.
