Module agent 

agent_step: the questions a browser agent asks for one step, built from the page’s element table the way jev-ultrafast’s choose builds them (jev_ultrafast/model.py, MIT, Browser Use). One operation head picks CLICK, TYPE_TEXT, SELECT, a page control such as SCROLL_DOWN, DONE or BLOCKED, and each operation with candidates gets a <op>_target head over the element indexes, so one request answers both what to do and where. AgentStep::decide checks the answers as jev-ultrafast’s validate_choice does and maps them back to the action to run.

The snapshot is what jev-ultrafast’s snapshot.js returns: url, title, text and actions, where an action has id, kind (click, fill, select, or anything else for a page control), and for elements node, label, role and value. The body is the same one jev-ultrafast sends, key for key and in the same order, so answers can be compared with Jev’s.
