What it is
A delegated browser executor for parent agents. A parent gives a bounded task; Jev selects one typed browser action from the current snapshot, agent-browser runs it, and the loop returns success or a structured handoff.
How it uses Jev
Jev chooses the next typed operation and target from the current page snapshot. The result is executed by agent-browser; the loop returns success or escalates ambiguity, repetition, or stuck states to the parent. Classification sends one typed, profile-driven batch to Jev.
Primitives:choice
Technique worth stealing
Keep the decision loop typed and bounded; escalate ambiguity or stuck states as structured handoffs instead of generating browser code.
Try it
npm install -g agent-browser jev-agent-browser; export TYPESAFE_API_KEY=...; jev --url ... --goal '...' --max-steps 6
