Select the next agent tool before generating arguments with Jev
Added to DistroCool on 2026-11-04 · Discovery date, not a release announcement
Jev Agent introduces a separate, fast tool-choice step that picks the winning tool from up to 255 options before passing context to an LLM to generate tool arguments.
Why it matters
In agents with dozens of available tools, feeding full schemas into an LLM on every step increases latency and token costs. Decoupling tool selection from argument generation cuts round-trip time on multi-step workflows.
