it's f*cking insane Jev sat between GPT and me, killing

Placed Jev between GPT and the user to reject drafts breaking rules, then found the agent went silent with no default branch, requiring a second agent to unstick it.

your checker needs a branch for the moment it goes quiet:

> let it through tagged unverified and keep moving

> hand the risky span to the big model

> park it in a queue and retry in a minute

> wake a human when the action is irreversible

70-500 ms

one Jev call, by TypeSafe's own number. a half-second checker still takes down the whole pipeline when it has no default.

Where this case fits

Filed under agents & workflows. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the agents & workflows page.
