Jev Use

Overview

Splits an agent loop by whether a step must produce text. Steps that only produce a decision - is the build done, which of these 30 elements to click, is this shell command safe, keep or drop this message - are handed to Jev, TypeSafe's judgment model, which answers typed yes/no, pick-one and score questions about a state in one forward pass instead of generating tokens. The agent stays the planner and the writer; Jev takes the quick calls.

Everything Jev should not decide comes back under a typed escalation contract, so the handoff is explicit in both directions rather than a guess.

When to Use This Skill

• Use when the next step is a judgment over context you already have ("did X succeed?", "which option?", "how bad is this?") rather than something to write.
• Use when you are about to check the same state several times in a row, so the questions can be batched into one call.
• Use when you want a risk check on a proposed tool call before running it.
• Do not use when the step must produce new content - text, code, free-form tool arguments - or when the options cannot be enumerated. Those are structurally the model's own work.
