 ```js

+If the user later asks for the link in a clickable form (e.g. "give me the live url"), surface it in your reply as a markdown link — `[Live view](<liveUrl>)` — which the TUI renders clickable. Tool stdout is not auto-linkified, but markdown in your assistant message is.

 Stash `id` somewhere (a `globalThis.cloudBrowserId = id` is fine, or the snippet's return value) — you need it to stop the browser later.

 Before the first `browser_execute` call of a session, you MUST read `{{SKILLS_DIR}}/BROWSER.md`. It defines the snippet model, the three connection methods (local user Chrome, isolated debug-port Chrome, Browser Use cloud browser), the workspace pattern, the `session` API surface, and gotchas. For cloud-browser specifics, also read `{{SKILLS_DIR}}/cloud-browser.md`.
 
+Always pass a clear, concise `description` of what the snippet does in 3-7 words (e.g. "Connect to local Chrome", "Scrape product titles", "Screenshot homepage"). It surfaces in the TUI as the call's title.

 - `session` — the live CDP `Session`. You call `session.connect(...)` once at the start of your work; subsequent snippets reuse the same connection. Domain methods follow `session.<Domain>.<method>(params)` and return Promises.
