ax_activate

Activate an exact actionable node from a fresh axread; rejects stale snapshot IDs and reports route=ax\

ax_read

Canonical ax:read: read semantic labels, text, values, roles, actions, state, and optional bounds through macOS Accessibility or Windows UIA, without a screenshot. Returns an ephemeral snapshot/node protocol and explicit coverage/status.

batch_actions

Run a sequence of input actions in one call.

click_mark

Compatibility action for the latest numbered mark; prefer generation-safe axactivate.

ocr

Recognize on-screen text via Apple Vision (on-device, no model files). Returns each text line with a clickable center — read and click text on canvas/Electron/game surfaces where marks are empty. CJK + Latin.

screenshot

Capture the whole display or a single window= — use for layout, icons, colors, images, canvas, and visual verification after semantic/OCR paths.

wait

Pause for a specified number of seconds.

zoom_region

Magnify a rectangle of the last screenshot at native resolution — reads small targets on surfaces with no Accessibility tree.
