Functions exposed to the LLM to take actions

Name	Description
start_captureA	Begin a screen-capture session. mode='fullscreen' works on every platform; mode='window' is Windows-only and requires `target` to be either a window-title substring or a hex hwnd (e.g. 'Notepad' or '0x1a2b3c').
stop_captureA	End the current capture session.
capture_nowA	Take a single screenshot on demand. Returns frame metadata (id, size, phash, timestamp) — NOT the image bytes. Use analyze_screen to actually read the content.
set_pollingB	Enable or disable a low-frequency background polling loop that keeps the frame buffer fresh. Default interval is 3 seconds.
list_windowsA	List visible top-level windows. On non-Windows platforms returns [].
analyze_screenA	Send recent frames to the configured vision provider along with the user's question, and return the model's answer. lookback_frames controls how many of the most recent frames to include (default 3).
