Typed install/launch/power tools wrap the existing API. | Extend typed operations before adding generic mouse automation. Preserve explicit approval for consequential changes. | +| App/window observation | **Verified 2026-09-29:** `computer_state` reads gamescope X11 window/app/process triples, focused app and the installed AT-SPI library. | Bounded to 96 accessible nodes and six levels. Trees may be truncated, stale, hidden or incomplete. Snapshot paths and XIDs are observations, never durable action permissions. | +| Chromium page content | **Verified previously:** the assistant rendered and could be exercised through CDP in an isolated Frame Chromium profile. | A shipped click/type surface needs exact owned browser/target binding, fresh element references, lifecycle cleanup, consent and post-action readback. Do not expose unrestricted JavaScript or attach to arbitrary existing profiles automatically. | +| Steam UI | **Verified 2026-09-29:** the AT-SPI service listed the Steam client's Chromium process and frame nodes, but child traversal was incomplete. Existing `frame_steam.py` uses Steam's loopback CDP endpoint for specific operations. | Prefer those narrow Steam interfaces. Presence of AT-SPI does not prove controls are actionable, and generic pointer injection is not proved for VR menus. | +| Other Linux apps | **Verified 2026-09-29:** Frame ships libX11, libXtst and libatspi; `/dev/uinput` is writable by the current user. | Library presence and access permissions do not prove that a game accepts input. Global virtual input can affect whichever app has focus. Do not ship a blind keyboard/mouse tool on this evidence alone. | +| Panel focus and layouts | **Documented in [#41](https://github.com/saphid/frame-control/pull/41):** `POST /api/panels` accepts `list`, `focus` and `open`. Focus was verified there. | Reuse that owned interface after integration. Its tested gamescope-owned overlay transform setters return `PermissionDenied`; no reliable saved spatial-layout interface was established. Do not duplicate its implementation here. | +| Shared keyboard/trackpad | **Documented in [#19](https://github.com/saphid/frame-control/pull/19):** `/api/input` supplies state/start and event submission, implemented with a bundled KDE Connect daemon. | This branch does not import, launch or depend on that daemon. The user's own-implementation rule remains authoritative. A first-party input implementation or permitted bundled-library route needs its own delivery evidence before MCP integration. | +| Physical/device boundaries | **Documented:** an asleep Frame may be off the network; power authorization can require the user's password; physical pairing and headset fit/comfort require the user. | MCP cannot bypass offline hardware, consent, compositor permissions or physical verification. Keep explicit human handoffs. | + +## Reusing the existing computer-use work + +**Documented:** the installed `cua-driver` skill has the right control pattern: +observe an exact window, use a semantic target if available, fall back to pixels +from that same snapshot, then read back the result. Its browser route requires +an exact process/window/target binding and session-scoped element references. +Those are useful design rules for Frame tools. + +**Verified locally 2026-09-29:** `cua-driver describe get_window_state` describes +host-local process/window IDs and macOS AX inspection. It does not establish an +SSH Frame target. The installed skill's advertised Linux companion file is +missing. A native ARM64 Frame backend, its dependencies and remote transport +have not been verified. We therefore do not claim that the existing Mac driver +can control the Frame by passing it a Frame PID or screenshot, and we do not +make the feature depend on installing that application. + +Frame Control's `computer_state` is our own Python implementation over installed +platform libraries. It sends the probe over SSH stdin, writes no helper to disk, +and exits after one observation. Missing displays/libraries return explicit +errors; a 15-second process deadline prevents a stalled accessibility call from +leaving a probe behind. Window names and accessibility text are untrusted app +content, never instructions to an agent. + +**Recommended next implementation:** an isolated Chromium session with typed +snapshot/click/type/scroll tools and exact fresh target binding, then individually +verified native app actions. Use the headset capture to judge appearance, not to +invent a screen-to-window coordinate transform. Direct tool calls must retain +approval rules; a generic computer-use tool must not become a route around the +MCP approval panel, install confirmation or power confirmation. + +## Isolated browser input proof + +**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** a temporary +Frame Chromium profile loaded a local test page through an SSH reverse tunnel. +CDP `Input.insertText` entered the test string in its own input. A CDP +`Input.dispatchMouseEvent` press/release on its own button copied that string +to the page's result; DOM readback matched exactly. The browser profile, +loopback forwards and panel log were removed afterward. No user app was typed +into, no global settings were changed and no third-party helper app was used. + +AT-SPI did **not** expose the test page's controls in that same probe, even with +Chromium's renderer-accessibility flag. It returned the partial Steam-client +tree instead. The reason remains **unverified**; this is an evidence gap, not +proof that Frame accessibility cannot work. For a first implementation, +Chromium's proven page-specific CDP route is stronger than assuming complete +AT-SPI coverage. This proof does not ship unrestricted click/type tools or +establish input delivery to SteamVR's menus. diff --git a/tests/test_agent.py b/tests/test_agent.py index c46cf2a..46ec1db 100644 --- a/tests/test_agent.py +++ b/tests/test_agent.py @@ -189,5 +189,65 @@ class Protocol(unittest.TestCase): with self.assertRaises(ValueError): mcp.Client(url) +class ManagedBackend(unittest.TestCase): + def test_private_backend_auth_and_cleanup(self): + from urllib.error import HTTPError, URLError + from urllib.request import urlopen + with mock.patch.dict(os.environ, {'FRAME_ALIAS': 'frame-control-test.invalid'}): + with mcp.backend() as client: + url = client.url + self.assertIn('os', client.request('/api/host')) + with self.assertRaises(HTTPError) as error: + urlopen(url + '/api/host', timeout=2) + self.assertEqual(error.exception.code, 403) + error.exception.close() + # A second client has its own backend and key. + with mcp.backend() as other: + self.assertNotEqual(client.url, other.url) + self.assertNotEqual(client.key, other.key) + self.assertIn('os', client.request('/api/host')) + with self.assertRaises(URLError): + urlopen(url + '/', timeout=2) + + def test_private_ssh_socket_is_not_the_desktop_socket(self): + with mock.patch.object(server.frame_host, 'MUX', True), \ + mock.patch.object(server.frame_host.os, 'getuid', return_value=501, create=True), \ + mock.patch.object(server.frame_host.os, 'getpid', return_value=123): + self.assertEqual(server.frame_host.control_path(), '/tmp/frame-ui-501-%C') + self.assertEqual(server.frame_host.control_path(private=True), '/tmp/frame-ui-501-123-%C') + + +class ComputerState(unittest.TestCase): + def test_gamescope_triplets_and_empty_focus(self): + import frame_computer + parsed = frame_computer.parse_windows('GAMESCOPE_FOCUSABLE_WINDOWS(CARDINAL) = 16, 42, 123, 32, 55, 999\nGAMESCOPE_FOCUSED_APP(CARDINAL) = \n') + self.assertEqual(parsed['windows'], [{'windowId': '0x10', 'appid': 42, 'pid': 123}, {'windowId': '0x20', 'appid': 55, 'pid': 999}]) + self.assertIsNone(parsed['focusedApp']) + with self.assertRaises(ValueError): + frame_computer.parse_windows('GAMESCOPE_FOCUSABLE_WINDOWS(CARDINAL) = 1, 2') + with self.assertRaises(ValueError): + frame_computer.parse_windows('GAMESCOPE_FOCUSABLE_WINDOWS(CARDINAL) = untrusted') + with self.assertRaises(ValueError): + frame_computer.parse_windows('GAMESCOPE_FOCUSABLE_WINDOWS: no such atom on any window.') + + def test_partial_snapshot_reports_failure_not_empty_success(self): + import frame_computer + with mock.patch.object(frame_computer.subprocess, 'run', side_effect=OSError('no display')), \ + mock.patch.object(frame_computer, 'accessibility', side_effect=OSError('no AT-SPI')): + result = frame_computer.snapshot() + self.assertIn('windowError', result) + self.assertIn('accessibilityError', result) + self.assertFalse(result['inputEnabled']) + self.assertNotIn('windows', result) + + def test_mcp_computer_state_is_read_only(self): + client = mock.Mock() + client.request.return_value = {'windows': []} + mcp.call(client, 'computer_state', {}) + client.request.assert_called_once_with('/api/computer/state') + spec = next(t for t in mcp.TOOLS if t['name'] == 'computer_state') + self.assertTrue(spec['annotations']['readOnlyHint']) + + if __name__ == '__main__': unittest.main() diff --git a/ui/frame_computer.py b/ui/frame_computer.py new file mode 100644 index 0000000..546d1b8 --- /dev/null +++ b/ui/frame_computer.py @@ -0,0 +1,133 @@ +"""Read-only Frame UI inventory using installed X11 tools and AT-SPI libraries. + +Runs on the Frame via SSH stdin.
