Chrome shows a "WebPilot started debugging this browser" bar while a task runs; it goes away when the task ends, and clicking **Cancel** on it stops the task. +- Chrome refuses the debugger on pages that contain another extension's frame, which password managers (LastPass, 1Password...) and tools like Grammarly add to many pages, including Gmail, and detaches it when such a frame appears mid-task. It also can't attach while another tool is debugging the tab. On those pages WebPilot switches to page scripts (`src/dom-browser.ts`, `src/page-scripts.ts`): it reads the visible page into the same snapshot format and acts with DOM events. The flight log notes the switch; each navigation tries the debugger again. - Pages are read from Chrome's accessibility tree and acted on with real mouse and keyboard events, so sites treat them like your own input. - The same core runs in the desktop app and the extension: `lib/core/run-task.ts` (the task flow), `lib/cdp/` (the CDP driver and accessibility-tree snapshot), `lib/jev/` (fast mode), `lib/safety.ts` and `lib/model-client.ts`. - The agent runs in the extension's background service worker (`src/engine.ts`), one session per tab; panels are views connected over a port. While a task runs, the worker keeps itself alive. - Requests about the open page that reading alone can answer ("summarize this", "what does this say about X") skip navigation and clicks and stream the answer straight from the page. Other requests that only find or read information use fast mode: Jev picks each click in ~0.3s and the model writes text and the answer. Requests that change something (buy, book, send, delete, submit) use the careful model planner. - Answers stream into the panel as they are written; Jev then checks them against the page, and an unsupported answer is redone (first by Jev looking closer, then by the model). - Before an irreversible click (buy, place order, checkout, send, delete, publish, unsubscribe...) the panel shows **"Hold on — this can't be undone"** with Allow and Cancel. Cancel ends the task there; say "go ahead" to continue. +- WebPilot never types into password, one-time-code or card fields and never makes up usernames or other personal details.
