Agent tooling — built on Jev
Tools that make agents decide faster. The common shape is a reflex router: keep the agent state, ask a few typed questions — next action, needs human, complexity — and branch in code, rather than paying multi-second generative latency per step.
This is the largest category in the catalog and the one most likely to overlap with your own stack. Skim it for the pattern you need, then check the use cases on this site for a written composition you can adapt.
