Ergonomic wrapper over CDP's Page.handleJavaScriptDialog that accepts or dismisses alert/confirm/prompt/beforeunload dialogs blocking a page. Unsticks pages whose JS thread is frozen by an unhandled dialog — symptom is that browser_snapshot, browser_console, browser_click etc. start hanging or erroring. - action='accept'|'dismiss' required; prompt_text optional for prompt() - target_id auto-resolves when exactly one page tab is open; with multiple page tabs, errors with the tab list so the agent picks one - Shares browser_cdp's check_fn gate — only appears when CDP is reachable (/browser connect or browser.cdp_url in config). Hidden otherwise so backends that can't use it don't see it. - Safe as a probe: CDP returns a clean 'No dialog is showing' error when nothing's pending, which we pass through verbatim Dialog detection (knowing a dialog is open without being told) is NOT included — it requires persistent CDP subscriptions per session, a larger architectural change. Documented as a follow-up; agents infer from symptoms and use this tool to recover. Tests: 11 new unit tests against mock CDP server covering the wrapper (action validation, auto-resolve with 0/1/multiple page targets, explicit target_id accept/dismiss flow, prompt_text passthrough, shared gate with browser_cdp, registry dispatch). E2E probe case against real headless Chrome passes. Positive-case real-Chrome E2E is blocked by Chromium's headless auto-dismiss behavior when no persistent listener is attached — unit tests exercise the exact CDP protocol we send, so the handling path is protocol-verified; headful real-browser usage (the actual /browser connect case) keeps dialogs alive via the Chrome UI. |
