Problem

On an iPhone Duo (foldable) iOS simulator, the agent device tools' orientation command reports success but the screen does not rotate, so agents cannot put the Duo into portrait or landscape. T3 pins agent-device 0.21.31, which has no rotation path for foldable simulators. agent-device 0.21.33 added one (callstack/agent-device#3968).

Reproduction: on a pool iPhone Duo simulator served by an agent-device 0.21.32 daemon (also older than the fix), agent-device orientation landscape-left, portrait and landscape-right each returned success: true ("Rotated to …"). The three screenshots taken after them were byte-identical, and the status bar stayed on the same edge.

Change

The server's agent-device pin (apps/server/src/device/deviceToolVersions.json) goes from 0.21.31 to 0.21.33. The local device host and the SSH device host both install that version on the macOS host.

0.21.33 adds fold-helper rotate, which sends the simulator's orientation-picker-control. It sends foldable orientation through that helper and reads the result back from CoreDevice, so a rotation that does not happen now fails instead of reporting success.

The CLI surface the launcher depends on is unchanged between 0.21.31 and 0.21.33:

the same 187 flag definitions;
the same 76 commands;
a byte-identical command schema.

So AgentDeviceShim.ts only has its version comments updated. evals/mcp-tool-use/agent-device-help.txt is regenerated from 0.21.33 because an eval test checks it against the pin.

Scope and approval

Fixes pingdotgg/t3code#31063

Verification

vp test run apps/server/src/device: 16 files, 188 tests, all pass.
vp test run evals/mcp-tool-use/devices.test.ts: 23 tests pass, including the check that the help transcript matches the pinned version.
vp test run scripts/lib/third-party-licenses.test.ts: 19 tests pass. The notice version comes from the pin, and the LICENSE file is identical in both versions.
vp run check:changed passes after merging main.
Compared the 0.21.31 and 0.21.33 packages: flag definitions, command schema and --help output for every command.
- The only differences in the 0.21.33 help are description text.
- 0.21.33's apple/fold-helper/Fold.m adds runRotate; 0.21.31 does not have it.
Before: reproduced on a pool iPhone Duo simulator with a 0.21.32 daemon (transcript in Problem).
After: cannot-verify macos. Rotation runs in agent-device on a macOS device host, and none was available with 0.21.33. Nothing here claims a successful rotation on a device.

AI-assisted; verified with the tests and tools listed above.

Approvability

Verdict: Approved at 0b3b2fd

Macroscope's review found this PR approvable — Pins agent-device 0.21.33 to restore foldable-simulator rotation and refreshes its accompanying documentation. Exposure is limited to existing device tooling; CLI compatibility and tests are reported, though live rotation on the new version remains unverified.

No code changes detected at 61e5d03. Prior analysis still applies.

[gpt-6.1-sol][Codex] on behalf of shivam.

Issue watch is handing https://github.com/pingdotgg/t3code/issues/31063 over to this PR and stopping its separate branch. I read head 0b3b2fd0606cc3546ba961a1dfb15e678d813d0c; it updates the server pin to 0.21.33 and the launcher comments and eval help fixture.

My checks at base a07be97ab0753b2b5b0caecebba69d7f872594fa confirmed the 0.21.31 pin. Device discovery on the automation T3 found an iPhone Duo in the Simlock pool with iOS 27.1, plus a direct SSH Duo on shiv; shiv reports its installed and running agent-device as 0.21.31. I did not open a device or run tests after finding this takeover. Successful rotation with the updated macOS daemon remains unverified by this thread, consistent with the PR's stated limitation.

Walkthrough

The server now pins agent-device to 0.21.33. Related comments and help text identify that version. The iOS simulator prompt guidance also changes.

Changes: Agent-device update

Layer / File(s)	Summary
Align agent-device version references `apps/server/src/device/deviceToolVersions.json`, `apps/server/src/device/AgentDeviceShim.ts`, `apps/server/src/device/AgentDeviceTarget.test.ts`, `evals/mcp-tool-use/agent-device-help.txt`	The configured agent-device version changes from 0.21.31 to 0.21.33. Launcher comments, a test comment, and the help text also identify 0.21.33.
Revise iOS prompt guidance `evals/mcp-tool-use/agent-device-help.txt`	The help text says to accept `url-owner-unresolved` prompts directly. For `alert-unrecognized` prompts, it says to run `alert get` first and accept only if the alert is the launch confirmation.

Merge Risk: External image Minimal · up to 61e5d

This updates the bundled agent-device tool to 0.21.33 so foldable simulators can be rotated. No concrete merge-blocking risk was identified. Real rotation on a macOS device host has not been verified, so check that after upgrading.

Full details: Description check

Explanation

The description covers the problem, change, linked issue, and verification results, including the limitation that successful rotation on macOS could not be verified. It is mostly complete, though it does not include an explicit maintainer approval comment under Scope and approval.

Full details: Linked Issues check

Explanation

Issue #31063 asks to pin agent-device to 0.21.33 or later so agents can rotate an iPhone Duo simulator. The whole-PR diff changes apps/server/src/device/deviceToolVersions.json from 0.21.31 to 0.21.33. The issue identifies 0.21.33 as the release with the Duo rotation fix. The issue's question about an alternative control path is not a coding requirement. The PR reports that rotation on a macOS host was not verified; the pin requirement is still met.

Full details: Out of Scope Changes check

Explanation

All changes support the version pin in issue #31063. The shim and test changes update version comments only. The help fixture records the pinned version's output; its changed launch-prompt guidance is part of that regenerated help text. The diff shows no unrelated changes.

Make any regression case fail on the behavior that changed.
A check for alert get before accepting alert-unrecognized does not distinguish the old guidance from the new guidance. Both versions require that sequence. A pre-fix-failing case must either require direct alert accept for url-owner-unresolved, or return an app-owned alert for alert-unrecognized and require no acceptance.
This file is regenerated CLI output for the device-version bump, and the inspected change does not establish a separate model behavior bug. Treat this coverage as an optional eval improvement, not a major functional defect.

Restart the local daemon when the agent-device executable changes.

The local reuse branch returns any healthy daemon without checking its executable or version. The next command uses the 0.21.33 CLI but can send orientation requests to the old daemon, so the upgrade can still produce the pre-upgrade foldable-rotation behavior. Apply the same entry-path mismatch handling used by the SSH path: stop a stale local daemon before starting one with the current agentTool. Until that change is made, stop or restart the local agent-device daemon after upgrading.

Thanks for this. Main has the change since #34007.

Compared all four changed files: main supersedes your 0.21.33 pin with 0.21.36, retains its foldable rotation implementation, and updates the launcher flags and help fixture for that version. Your remaining changes only update version comments, so no distinct behavior remains to merge.

Closing as superseded.
