Moving an agent's small decisions from the main model to Jev
The author suggests auditing sentences an agent writes just to say yes or no, and routing three checks to Jev: tool-call approval, model tier choice, and whether a task is really done, at about $0.42 per 10,000 decisions versus roughly $300 via the main model, plus a paste-ready audit prompt.
Jev engineering tip: open your agent's last session and count how many times it wrote a sentence just to say yes or no put the small decisions somewhere that can't write a sentence Your agent keeps writing, editing, researching. Jev sits underneath it and only gets involved at three points: → before a tool call runs: safe, or does a human need to see this first? → when the task needs a model: the cheap one, or the expensive one? → before marking done: did the test actually pass, or does it just look finished? Jev answers in under half a second, and that speed is why 10,000 of these decisions cost 42 cents through it. route them through your main model instead, and the same 10,000 cost roughly $300 the full loop your agent runs the main session Jev checks every tool call before it executes Jev routes the task to the right model anything under the confidence threshold escalates back up Most agents never audit which fork is which. They just pay full price for both. paste this into your coding agent: "Audit my agent's decision points before we change anything. > List every model call in the last real run. For each one: what triggers it, what the output gets used for. > Classify each call: could every valid answer be listed in advance, would a person settle it on a glance, does it happen often enough to matter. Mark GENERATION or DECISION. > For every DECISION call, show what it would look like as a bounded decision instead, plus a confidence threshold below which it escalates back to the main model. > Report which calls stay, which move, and the real cost difference at current volume. If there's not much to gain, say that plainly. Show the classification as a table first. No changes until I say go."
