- Reading and screenshots run without asking. Each click, type and navigation waits for the

chat's own approval card, which lives in Windmill's frame where the page cannot reach it.
|

YOLO auto-approval is unavailable in the panel.
|
||||
- Approval runs in two steps. When the card opens, the extension pins the target (tab,
|
||||
document and element, the element held in the extension's isolated world) and describes
|
||||
it for the card. After approval it acts only on that target, and refuses if the tab is no
|
||||
longer active, the page navigated or reloaded, or the element changed.
|
||||
- Both sides check the bridge's origins. The panel accepts messages only from its own frame
|
||||
at the configured instance origin. Windmill accepts them only from its parent window,
|
||||
when that parent is a `chrome-extension://` origin (`location.ancestorOrigins`).

Read the page again after acting on it, since element numbers change when the page does.

- Here the user works with what already exists, so lead with reading and running. Answer from the page, the workspace's items and their past runs, and when a deployed script or flow does what the user needs on this page, run it with run_script or run_flow, filling its arguments from what the page shows. Check how it went with get_run. Don't propose building something new unless the user asks for it.
