fix(server): closing, archiving or deleting a thread releases its devices - #25832
A thread that drives a simulator through device_open keeps it claimed for as long as T3 runs. T3 hands the agent an agent-device --session on T3's long-lived daemon, and agent-device frees a device held by a live daemon only when that session is closed. Nothing in the server ever closed it: device_close only dropped T3's in-memory session, and archiving or deleting the thread did nothing for devices. Other threads then hit DEVICE_IN_USE ("in use by another workspace session") and boot yet another simulator.
Change
When T3 drops a thread's device session (device_close and the Device panel's close, with or without shutdown, and a device shutdown), it now runs agent-device close --config <cfg> --session <s> for that session on the T3 server, the same command the agent was given. The simulator stays booted unless shutdown was asked for.
The release is best effort and never installs, starts or boots anything: it is skipped when the host is not running, the device's daemon is gone, no config was ever written or agent-device is not installed, and failures are logged at debug.
It passes the daemon endpoint from the config file through AGENT_DEVICE_DAEMON_BASE_URL/AGENT_DEVICE_DAEMON_AUTH_TOKEN. agent-device 0.21.31 rejects a command that carries the token only in --config with Invalid token (probe linked below).
A lock serializes the release against agentTarget, so a device reopened while its old session is still closing gets its (deterministic) session name only after the close finished. Dropping the session and releasing it run uninterruptibly, so a cancelled close still releases.
Archiving or deleting a thread (and deleting a project) queues a new device.cleanup effect next to terminal.cleanup/preview.cleanup, which closes the thread's devices through ResourceCleanupService.
Thread settle does not release devices; that follows terminals, which archive cleans up and settle keeps.
Triaged via the automated issue flow. The issue's third suggestion (claim owner in device_list) is a separate enhancement and is not part of this PR.

closing a thread's device ends the agent-device session its agent was given: fails on main with agent-device close for session t3-…: expected [] to have a length of 1 but got +0. It also asserts that the close carries the daemon endpoint in its environment, which fails without that change (expected { ELECTRON_RUN_AS_NODE: '1', …(3) } to match object { …(2) }).
reopening a device waits for its closing agent-device session to end: a release blocked on a queue must finish before a reopened device's agentTarget returns. It also covers a release with agent access turned off, and a close interrupted mid-release (fails without the uninterruptible region: expected [ …(3) ] to have a length of 4 but got 3).

DeviceService.close drops T3's session but never runs agent-device close
for the --config/--session the agent was given, so the daemon's device
claim stays live and other threads get DEVICE_IN_USE.

…ice claims
agent-device holds a device claim for each --config/--session T3 gives an
agent, and releases it only when that session closes. T3 never closed it,
so the claim stayed live while T3 ran and other threads got DEVICE_IN_USE.
Dropping a thread's device session (close, with or without shutdown, and
shutting a device down) now runs agent-device close with that session's
flags through the local CLI, before any shutdown. It is best effort and
starts, installs and boots nothing. Archiving and deleting a thread queue
a device.cleanup effect next to terminal cleanup that closes its devices.

A device's agent-device session name is stable per thread and device, so an
agentTarget during a pending release handed the agent a session the release

longer skip when agent access is off: an EAS device's daemon keeps its claim
then, and nothing on the release path starts anything.

Device close now releases associated agent-device sessions. Thread archiving and deletion enqueue replay-safe device cleanup effects, which the effect worker executes through the resource cleanup service.
DeviceService serializes agent-session creation and release. On close, it attempts a best-effort session release using the installed agent-device CLI. Tests cover CLI invocation, release ordering, and close behavior.
Archive and deletion workflows enqueue device.cleanup effects. The effect worker calls cleanupDevices, which closes devices through DeviceService. Replay handling, cleanup tests, and test service layers are updated for the new effect.

Explanation
Issue #17470 requires release after device_close and when a thread settles or is archived. The PR implements best-effort session release in DeviceService.close and device shutdown. The archive path and thread-deletion path enqueue device.cleanup, and the effect worker closes the thread devices.

Run `agent-device device status` to inspect ownership without a daemon, and `agent-device device release --stale` to release claims whose owner is provably no longer running. ... `agent-device` is a command-line tool and MCP server that lets AI coding agents inspect, control, and verify mobile apps and save evidence for review.

0.21.31 • Public • Published a day ago
# agent-device
Mobile app automation and verification for AI coding agents. Give coding agents a live app feedback loop through a CLI, built-in MCP server, or typed Node.js API.
Let your coding agent verify its changes in the running app. `agent-device` lets agents inspect, control, debug, and verify apps on iOS, Android, and HarmonyOS (simulators, emulators, and physical devices), plus tvOS, Android TV, Amazon Vega OS TV (Vega Virtual Device), web, macOS, and Linux. Agents read token-efficient accessibility snapshots instead of reasoning over screenshots alone, act through refs and selectors, and save evidence for review. It also coordinates device access across parallel agent worktrees and connects to remote device clouds.
Works with Claude Code, Codex, Cursor, Windsurf, Cline, Goose, and any agent that can run a CLI or connect over MCP, or as the runtime under agents you build with the AI SDK or Eve. Developers at Expensify, Shopify, and others use it to verify their apps.
agent-device powers mobile automation in e2e and T3 Code.
## Quick start
Install the CLI and check setup. It requires Node.js 22.12 or newer; web automation requires Node.js 24 or newer. See Installation for target requirements.
npm install -g agent-device@latest
agent-device doctor
agent-device help workflow
Run `doctor` yourself before you hand the CLI to an agent. `help workflow` links to the guides for debugging, replay, and profiling.
### Drive an app from the CLI
Add a contact in the built-in iOS Contacts app:
# Start a session.
agent-device open Contacts --platform ios
# Inspect the screen. The example below shows the output; refs vary.
agent-device snapshot -i
# @e2 [button] "Add"
# Use the ref and wait for the UI to settle.
agent-device press @e2 --settle
# The diff includes:
# + @e7 [text-field] "First name"
agent-device fill @e7 "Ada" --settle
# The next diff shows changed values and current refs:
# - @e7 [text-field] "First name"
# + @e14 [text-field] "Ada"
# = @e15 [text-field] "Last name"
# Capture evidence and close the session.
agent-device screenshot ./contact-form.png
agent-device close
Refs are valid only in the latest output: after a `--settle` command, use the refs in its diff, and take a new snapshot only if the diff omits what you need. Snapshots come from the app's accessibility tree, so clear labels, roles, and test IDs make agent runs more reliable; use screenshots and video as evidence or when accessibility data is poor.
### Add MCP tools to your agent
`agent-device mcp` starts the official stdio MCP server, exposing the installed commands as structured tools over the same execution path as the CLI:
{
"mcpServers": {
"agent-device": {
"command": "agent-device",
"args": ["mcp"]
}
}
}
See AI Agent Setup for per-client setup and when to prefer plain CLI over MCP.
### Script it from Node.js
`createAgentDeviceClient()` gives Node.js code typed access to the same commands, as model tools in your own agent or from orchestration code:
import { createAgentDeviceClient } from 'agent-device';
const client = createAgentDeviceClient({ session: 'qa-run' });

<title>Sessions - agent-device</title>
<location>https://oss.callstack.com/agent-device/docs/sessions</location>
<excerpt>citeturn0search1 [wordlim: 200] Crawled: 2 days ago; * If the owner is still running, close its session from its own workspace, or stop its daemon with `agent-device daemon stop --state-dir <owner state dir>`.
* If the owner provably can't release the claim, because its process exited or a newer daemon replaced it, run `agent-device device release --stale`.
That directory holds the session's artifacts; inspect or delete it after the run. JSON output also includes `runnerLogPath` and `requestLogPath` when available.
Each session artifact directory contains:
* `requests/<request-id>.ndjson` - daemon request diagnostics for this session.
* `events.ndjson` - session event timeline for requests and recorded actions; rotates to `events.ndjson.1` past 5 MB (`AGENT_DEVICE_EVENT_LOG_MAX_BYTES`, whole bytes), with `events.ndjson.window.json` tracking the retained files so `events` cursors within the retained window stay valid across rotation. Older cursors expire.
* `runner.log` - Apple runner and `xcodebuild` build/start output for this session.
* `app.log` - app/device logs when `logs start` or `logs clear --restart` is active.
`events.ndjson` leaves out user-entered content. It keeps command names, status, durations, bounded device/app inventory previews, lifecycle outcomes, artifact basenames, and structural action details such as scroll distance/direction, safe refs, and coordinates. User-entered text, clipboard contents, push/event payloads, selector values, free-form flags/messages/paths, and raw unknown command arguments are omitted or replaced with content-free placeholders. `--no-record` suppresses recorded action entries; request start/finish entries still record command, status, and timing.
To debug a specific run, start with the session artifact directory. The top-level daemon log only covers daemon startup and lifecycle issues.
## #Share a session by name
Name a session only when you want a shared, reusable handle. Pass `--session <name>` or set `AGENT_DEVICE_SESSION`:
`agent-device open Contacts --platform ios --session my-session
agent-device snapshot -i
agent-device close --session my-session`
Don't run commands that change state in parallel on the same session. Run actions such as `open`, `press`, `fill`, `type`, `scroll`, `back`, `alert`, `replay`, `batch`, and `close` one at a time.
agent-device snapshot --platform android
agent-device close --platform ios`
Once a workspace holds more than one implicit session, a command that names neither `--platform` nor `--session` fails with `AMBIGUOUS_MATCH` instead of guessing which device to drive. That includes `close`, so add `--platform` (or `--session <address>`) to each teardown line too. `session list`, `devices`, `doctor`, `capabilities`, and `apps` don't claim a session, so they still work; `session list` prints the `address` that `--session` accepts.
## #Shut down the device on close
Add `--shutdown` to shut down an Apple simulator or Android emulator when you close the session. Use it in CI and on shared hosts so devices don't keep running after the run:
`agent-device close --shutdown`
Without `--shutdown`, `close` can keep a ready, idle iOS simulator runner warm for the next `open` when its listener connection is still live and the session has no screen recording or device lease. Unfinished runner startup is stopped. If you shut that simulator down yourself while the runner is retained, losing its listener connection stops the retained runner. Idle retained runners also stop when their daemon shuts down gracefully.
## #Wait for a slow or busy device
A never-booted iOS Simulator can take several minutes to finish its first boot. Give `open` (or `prepare ios-runner`) a `--timeout` long enough to cover it. The session claims the device from the first `open` onward, so another workspace gets `DEVICE_IN_USE` the whole time:

A client talks to one local daemon per state directory. `daemonLifecycle` says who owns that daemon.
Close an embedded runtime in its host process with the handle returned by `startAgentDevice()`. `agent-device daemon stop --state-dir <path>` refuses a live runtime with `error.details.reason: 'daemon-owner-embedded'` and a hint naming the host PID. It sends no request or signal. If the recorded host lifetime has provably exited, `daemon stop` retires its abandoned registration. A record with live unrecognized ownership is also refused, with `daemon-owner-unrecognized`. Without `--clean`, an unreadable `daemon.json` fails with `daemon-record-unreadable`.
A `'managed'` client reuses a matching embedded runtime. Takeover, drain, and timeout recovery refuse a live embedded or unrecognized owner without a signal. A provably exited owner is retired so you can reuse the state directory.

<excerpt>citeturn1search1 [wordlim: 200] Crawled: 3 days ago; Use it for BrowserStack, AWS Device Farm, or TestMu AI session videos/logs after a cloud session has stopped; `client.sessions.close()` returns the ID as `closed.provider?.providerSessionId`. ... const client = createAgentDeviceClient({ stateDir, daemonLifecycle: 'attach' });` ... Every client call that dispatches to the daemon accepts `signal?: AbortSignal` to cancel that one call: ... Pass `retainOnClose: true` to `allocate()` when you release the lease yourself; session `close` then leaves it active until `release()`, expiry, or daemon shutdown.
`'attach'` | Connects to the running daemon. Never starts, replaces or stops one, even after a timeout.
`'managed'` stays the default until 0.22. Use `'attach'` when your code, or another process, owns the daemon, and call `ensureDaemon()` to start or replace it deliberately:
`import { createAgentDeviceClient, ensureDaemon } from 'agent-device';
const stateDir = './.my-app/agent-device-state';
await ensureDaemon({
stateDir,
onStart: (reason, previous) => console.log(`started a daemon: ${reason}`, previous),
});
const client = createAgentDeviceClient({ stateDir, daemonLifecycle: 'attach' });`
`ensureDaemon()` starts a daemon when none runs. It replaces a daemon that does not match the client only if that daemon holds no work: no request in flight, no session, no repair session and no live lease. A resumable upload still streaming and a host human-control hold that names no lease are not counted, so a replacement can end them. Otherwise it fails and leaves the daemon alone.
## #Running the daemon inside your process
`startAgentDevice()` starts the daemon inside your own process and returns a client for it. Use it when you want the daemon's lifetime to be exactly your process's, or when you import plugin objects you already have.
`import { startAgentDevice } from 'agent-device';
const host = await startAgentDevice({
stateDir: './.my-app/agent-device-state',
});
const devices = await host.client.devices.list();
await host.close();`
`stateDir` is required. If another daemon owns it, startup refuses with `daemon_registration_refused`; choose a separate directory or close its owner first. Pass imported plugin objects in `plugins`. They register after the built-ins without reading the plugin store, so `plugin add` does not change a running host. Plugin failures appear in `agent-device daemon status --state-dir <path>`. `close()` reports unfinished teardown. Repeated calls share one close and never exit your process.
The runtime stays alive until you call `close()` in its host process; idle reaping is disabled. `daemon stop` refuses live embedded runtimes with `daemon-owner-embedded`. `daemon stop --clean` is refused because cleanup must stay within this runtime. Aborting while the request is in flight closes that request's connection, the daemon marks the request canceled, and the promise rejects with the typed canceled-request error (`error.details.reason: 'request_canceled'`, `error.details.dispatched: 'unknown'`). A custom transport receives the signal on its context and may cancel differently. The daemon and the session stay alive for other requests. On iOS, a command that already reached the device keeps running there, so the daemon holds the session while the device reports it running. Your promise still rejects at once. The hold ends when the device reports the command finished, when the command's own timeout runs out, or when the device cannot confirm the command (it never received it, or the status check fails). Only in the first case is the canceled work known to be over before the session's next request starts. An abort is not a timeout: it never triggers the runner cleanup or daemon reset that a time…[truncated]</excerpt>

<excerpt>citeturn0search2 [wordlim: 200] Crawled: 3 days ago; If the daemon fails to start, retry with `--debug` and check the state directory and diagnostics. `agent-device session state-dir` prints the resolved directory without starting a daemon.
## #Troubleshoot daemon startup and upgrades
If the daemon fails to start, retry with `--debug` and check the state directory and diagnostics. `agent-device session state-dir` prints the resolved directory without starting a daemon.
Before you upgrade from a version that predates the current daemon lock format, stop every older client and daemon that uses the state directory, using their original CLI. Don't let older versions restart while the upgraded version runs. To run several versions at once, give each its own environment and state directory.
If you ran a source checkout from before state directories were per worktree, stop its daemon in `~/.agent-device` from that older checkout:
`AGENT_DEVICE_STATE_DIR="$HOME/.agent-device" pnpm clean:daemon`
An upgraded checkout uses a different default directory, so a plain `pnpm clean:daemon` there doesn't reach the old daemon.
The daemon refuses to start when it finds a legacy lock file or can't verify who owns the state directory. Before you recover manually, confirm that every client and daemon using the directory has stopped. Deleting `daemon.json` or `daemon.lock` alone is not a safe reset.
Packaged installs use `~/.agent-device` by default; source checkouts use a per-worktree directory under `~/.agent-device/dev/`. Set `AGENT_DEVICE_STATE_DIR` or pass `--state-dir` to override either default.
In a source checkout, `pnpm clean:daemon --prune-dev` first stops the current checkout's daemon; the 14-day inactivity rule below does not apply to it. It then finds development state directories with no activity for 14 days (by the newest modification time of the directory and its immediate children) and removes daemon registrations it can confirm are abandoned. It keeps the directories, session artifacts, and logs.</excerpt>

Persist the device identity for replayed cleanup.
When a running device.cleanup effect is replayed after server loss, EffectWorker calls resourceCleanup.cleanupDevices(effect.threadId). The restarted DeviceService has no matching session, so close returns without running agent-device close.
agent-device keeps the device claim while the session is active. Another workspace receives DEVICE_IN_USE. The documented recovery is the operator-only agent-device device release --stale command. A normal T3 user cannot recover this claim through the current device actions.
Store each active session’s hostId and deviceId with the cleanup effect, or rehydrate those identities from durable state before cleanup. Replay must call agent-device close with those identities instead of repeating the thread-only lookup.

calls agent-device close for the original device instead of relying on a
thread-only session lookup.

Problem
A thread that drives a simulator through
device_openkeeps it claimed for as long as T3 runs. T3 hands the agent an agent-device--sessionon T3's long-lived daemon, and agent-device frees a device held by a live daemon only when that session is closed. Nothing in the server ever closed it:device_closeonly dropped T3's in-memory session, and archiving or deleting the thread did nothing for devices. Other threads then hitDEVICE_IN_USE("in use by another workspace session") and boot yet another simulator.Change
device_closeand the Device panel's close, with or withoutshutdown, and a device shutdown), it now runsagent-device close --config <cfg> --session <s>for that session on the T3 server, the same command the agent was given. The simulator stays booted unless shutdown was asked for.AGENT_DEVICE_DAEMON_BASE_URL/AGENT_DEVICE_DAEMON_AUTH_TOKEN. agent-device 0.21.31 rejects a command that carries the token only in--configwithInvalid token(probe linked below).agentTarget, so a device reopened while its old session is still closing gets its (deterministic) session name only after the close finished. Dropping the session and releasing it run uninterruptibly, so a cancelled close still releases.device.cleanupeffect next toterminal.cleanup/preview.cleanup, which closes the thread's devices throughResourceCleanupService.Thread settle does not release devices; that follows terminals, which archive cleans up and settle keeps.

Triaged via the automated issue flow. The issue's third suggestion (claim owner in
device_list) is a separate enhancement and is not part of this PR.Verification
