ddupont 413ee1a286 feat(computer-use): background focus-safe backend — set_value, structured windows, MIME detection ... Extends the cua-driver computer-use backend to drive backgrounded macOS windows without stealing keyboard or mouse focus from the foreground app. All changes target the cua-driver MCP backend and the shared dispatcher. ## cua_backend.py **Window-aware capture**: capture() now calls list_windows + get_window_state instead of the removed capture tool. Prefers structuredContent.windows (MCP 2024-11-05+ cua-driver) for zero-parse window enumeration; falls back to regex-parsed text for older builds. Stores the selected (pid, window_id) as sticky context so subsequent action calls do not need a redundant round-trip. **Action routing**: click/scroll/type_text/key all carry the sticky pid (and window_id for element-indexed clicks). type_text routes through type_text_chars (individual key events) rather than AX attribute write -- WebKit AXTextFields reject attribute writes from backgrounded processes. **Key parsing**: _parse_key_combo splits cmd+s-style strings into (key, [modifiers]) and routes to hotkey (modifier present) or press_key (bare key) -- cua-driver actual tool names. **set_value method**: new set_value(value, element) calls the cua-driver set_value MCP tool. For AXPopUpButton / HTML select in a backgrounded Safari, AXPress opens the native macOS popup which closes immediately when the app is non-frontmost; set_value AX-presses the matching child option directly (no menu required, no focus steal). **focus_app**: reimplemented as a pure window-selector (enumerates list_windows, sets sticky pid/window_id) without ever raising the window or stealing focus. **list_apps**: fixed tool name from listApps to list_apps; handles plain-text response via regex when structured data is absent. **Structured-content extraction**: _extract_tool_result now surfaces structuredContent from MCP results, enabling the list_windows window array without text parsing. **Helpers**: _parse_windows_from_text, _parse_elements_from_tree, _split_tree_text, _parse_key_combo extracted as module-level functions. ## schema.py Added set_value to the action enum with a description explaining when to prefer it over click (select/popup elements, sliders, no focus steal). Added value field for set_value payloads. ## tool.py Routed set_value action through _dispatch to backend.set_value. Added set_value to _DESTRUCTIVE_ACTIONS (approval-gated). Fixed MIME-type detection in _capture_response: cua-driver may return JPEG; detect from base64 magic bytes (/9j/ -> image/jpeg, else image/png) rather than hardcoding image/png. ## agent/display.py + run_agent.py Guard _detect_tool_failure and result-preview logic against non-string function_result values: multimodal tool results (dicts with _multimodal=True) are not string-sliceable; treat them as successes and fall back to str() for length/preview.		2026-04-28 01:46:36 -07:00
