  "works": "Unattended, offline install of the 0.13.2 Linux x64 release (checksums OK) with runtime-only, skip-system and offline flags; no account or API key. The stdio MCP server (rmcp 1.5.0, protocol 2025-06-18) lists 4 tools: js, js_add_node_module_dir, js_reset, turn_ended. The first js call returns an API guide, so the model learns the API in-band. Window listing, app launch and binding by window id, coordinate clicks, typeCharacters, a Save click that wrote the file to disk, JPEG screenshots, js_reset and turn_ended all worked. With an accessibility bus running, element-index clicks worked (menus, Thunar buttons, a context menu, a new-folder dialog) and typeText filled a dialog field with accented, CJK and emoji text. Clear errors for an unknown window id, a click outside the window (refused, nothing sent), an unsupported key, and a timeout (kernel resets).",
  "breaks": "(1) typeText and paste could not type into Xfce Terminal in any mode tried ('window does not expose a Paste action', 'cannot identify the focused text field', or a ~10 s clipboard paste timeout); after the timeout a literal Ctrl+V character was left at the shell prompt, so a failed call still changed the app's input. (2) js_add_node_module_dir accepted an absolute folder that does not exist and returned true. (3) If the temp folder setting points to a missing folder, the server exits at startup and the client only sees 'Connection closed'; the reason is only on stderr. Not tested: Chrome control, audio, harness adapters (Codex CLI, Claude Code, Pi), updates, macOS and Windows.",
