act

Act on the page. For upload give args.files=[{name,text|base64}] inline. kind: click, dblclick, rightclick, hover, focus, type (ref+value), press (value=key), select (ref+values), check/uncheck, scroll, drag (ref=source, args.to=target ref, or args.to_target={text:"Drop here"} for a drop area without a ref; draggable elements are marked in the snapshot), upload, dialog (value=accept|dismiss for an open dialog; confirms are auto-dismissed, so for yes-flows first value=policy args={"confirm":"accept"} or value=accept_all, then repeat the click), back, forward, reload, cookies, storage, emulate. kind=steps with args.steps=[{kind,ref,value,...}] runs up to 20 in one call, stops at the first error, one final diff.

Argument	Type	Description
ref	string	ref from the snapshot, e.g. e12
args	object	any extra argument of the action, e.g. {"submit":true} for type, {"to":"e9"} for drag, {"button":"right"} for click
kind*	string
value	string	type: the text; press: the key (Enter, Control+A); select: the option; scroll: top\|bottom\|down\|up or pixels; dialog: accept\|dismiss; check/click need none
secret*	string	session secret from create_session
values	array	select: options; upload: file names from args.files

extract

Get data without acting: read (Markdown), links, tables, forms, outline, metadata, jsonld, schema (records by CSS selectors), find (query:"designed|first released" is a regex; or args.queries=["a","b"]; matching elements with refs; there is no separate find tool), console, network, downloads.
