Problem

t3_thread_send with mode: "restart" always failed on a running Claude thread with Claude cannot redirect an active run. Stop it first, then send the message., while the same call on a Codex thread restarts the turn. Claude (like Pi, Muse and ACP registry agents that turn native restart off, such as Copilot) can stop a turn and queue messages, but cannot restart a turn with new input, so CommandPolicy.decideSteeringExecution rejected every forced restart.

Reproduced on main 22dc6f9e98 with a dev server on a fresh database: a Claude thread runs python3 -c 'import time; time.sleep(150)' in the foreground, and a second thread calls t3_thread_send {threadId, mode: "restart", message} on it. The call fails and the sleep keeps running. The same call against a running Codex thread returns delivery: "restarted".

Change

  • message.dispatch with restart_active, on a provider that can interrupt and queue but not interrupt-and-restart, now queues the message first and stops the running turn. It reuses the path /goal already takes for "stop the turn, then run this next" (stopRunForQueuedCommand); goalStopRunId becomes queuedRunStop. The stop row reads "Stopped to send a new message".
  • The restart message does not inherit a queue hold left by an earlier Stop and takes queue position 1, so it runs ahead of other queued messages; older held messages stay held. A delegated-task result that was already queued still delivers first, as it does after /goal.
  • Providers with native interrupt-and-restart (Codex, OpenCode, Cursor, ACP) keep their path unchanged. A provider that cannot interrupt, a target that Stop already reached, and /compact or /logout turns keep the existing behaviour.
  • t3_thread_send reports delivery: "restarted" for this fallback. It reads the stop request from the send's own committed events, so a replayed send (same command id) gets the same answer.
  • docs/orchestration-v2/orchestrator-mcp-server.md describes the fallback.

Scope and approval

Fixes pingdotgg/t3code#32890

The reporter asked for exactly this behaviour: on a driver without native interrupt-and-restart, restart interrupts the turn and starts the message as the next turn.

Verification

Focused tests in apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts (provider harness with interrupt and queued messages but no interrupt-and-restart):

  • restarts by stopping the running turn when the provider cannot interrupt-restart: fails on main with CommandPolicyCapabilityUnsupportedError: … cannot satisfy interrupt_restart_steering; passes now (stop requested, the restart runs before the older queued message).
  • starts a restart that stops the running turn ahead of an older held queue: without the hold exemption the restart never starts (started: ["first", "second"]); passes now.
  • reports a restart that stops the running turn as restarted: sends, then Stop, then replays the same send; with delivery read from queue state it gives ['restarted', 'queued']; passes now with ['restarted', 'restarted'].
  • With Orchestrator.ts and ThreadManagementService.ts reverted to main (12f3244e05), all three fail; the first with CommandPolicyCapabilityUnsupportedError: … cannot satisfy interrupt_restart_steering.
  • At ff0b4188ac (main merged): SteeringCompletion.integration.test.ts, ThreadManagementService.test.ts, CommandPolicy.test.ts 73/73; vp run check:changed passes.

Runtime transcript, server-only (the only visible change is the stop row's text, "Stopped to send a new message", in the existing stop row), taken at 2eda81176f; later commits only merge main and edit docs: T3CODE_DEV_SEED=0 vp run dev on a fresh database per side, a scratch git project, real Claude Code and Codex CLIs. Thread A runs the foreground sleep(150); pgrep confirms the process before the send; thread B calls t3_thread_send {threadId: A, mode: "restart", message: "Stop sleeping and reply with just: restarted"}.

Not checked at runtime: Pi, Muse and Copilot (ACP registry), which take the same capability-gated path; covered by the harness tests only. No web or mobile client sends restart (follow-up behaviour is queue or steer), so there is no UI change to capture.

Approvability

Verdict: Approved at f05d37e

Macroscope's review found this PR approvable — Explicit restart sends can now stop a supported running turn and queue the replacement next when native interrupt-and-restart is unavailable. The fallback is capability-gated, preserves maintenance and Stop safeguards, and leaves ordinary sends unchanged.

Walkthrough

For eligible restart_active requests, the orchestrator queues the new message and stops the active run. sendToThread reports "restarted" when stored dispatch events show an interrupt request for another run.

After an accepted restart finishes, a retry may fail instead of returning its result. Some documented restart cases can also leave the active turn running. These risks should be resolved or explicitly accepted before merge.

Full details: Linked Issues check

Explanation

Issue #32890 requires t3_thread_send with mode: "restart" to stop a running turn and start the supplied message next when the provider lacks native interrupt-and-restart. Orchestrator.ts implements this fallback for interrupt-capable providers that support queued messages. It gives the replacement priority over older held messages. The integration tests cover stopping and restarting, queue ordering, and stable delivery: "restarted" reporting. The MCP documentation describes the fallback. The PR summary reports a Claude runtime check and unchanged Codex behavior.

Full details: Out of Scope Changes check

Explanation

The reported changes to Orchestrator.ts, ThreadManagementService.ts, the steering integration tests, and the MCP documentation support the fallback, its delivery result, or verification and documentation. No unrelated change is evident.

Test the replay after the stop settles.

The test retries without running the interrupt effect, so it does not cover replay after the provider turn stops. started.length === 1 also does not show that Stop held the replacement.

Drain the worker and await the interrupted provider-turn event before replaying. Assert that the replacement remains held and that the replay reports delivery: "restarted".

On the CodeRabbit nitpick about the replay test in SteeringCompletion.integration.test.ts (lines 1696–1704), leaving it as is:

  • After the Stop settles, the thread has no running turn left. sendToThread rejects any restart/steer send with ThreadManagementNoSteerableRunError before it reaches the command receipt, so a replay in that state cannot report a delivery at all. I tried this ordering while writing the test. That limit applies to every steer replay on main and is outside this fix.
  • The test replays while the Stop is still pending. In that window, the replacement's queue state (held by Stop) and the send's own events disagree. Before the last commit this test failed with ['restarted', 'queued']. started.length === 1 only confirms the replacement had not started; the hold itself is covered by starts a restart that stops the running turn ahead of an older held queue.

Replay accepted restarts before requiring an active turn.

If the replacement completes and no turn is running, a retry with the same clientRequestId fails before receipt replay. After a lost response, the caller cannot recover the accepted restarted result. Thread reads can show the message and run, but do not return that result.

Allow accepted receipts to replay before the steerable-run guard. Keep the guard for new restart commands.

  • docs(server): state when the restart fallback applies0ebbb6a

On the CodeRabbit outside-diff finding (ThreadManagementService.ts:895-904, replay an accepted restart before the steerable-run guard): leaving it out of this PR. The guard runs before receipt replay for every steer and restart send on main, whatever the provider, so a replay after the turn settles fails the same way on Codex today. Moving the replay ahead of the guard changes idempotency for all steer sends and belongs in its own change; this PR keeps to the restart fallback for #32890.

Reject a restart when interrupt planning fails.

Honor explicit restart for /goal clear.

On Claude, /goal clear with no active goal enters the goal branch before the restart fallback. It can queue behind earlier messages without stopping the turn.

Apply the restart fallback for an explicit restart, while preserving the existing behavior for ordinary goal sends. Add a test for this case.

10before queueing the message; preserve the existing behavior for ordinary goal

Leaving this out of the PR. A goal command takes the goal branch before the restart fallback on every provider, Codex included: by design it never joins a running turn and stops the run only when it starts or ends goal work, so /goal clear with no active goal queues on main today. Changing what restart means for goal commands is a separate decision from #32890.

@juliusmarminge Understood. I withdraw the request to change /goal clear behavior in this PR. The existing goal-command behavior applies across providers, and changing it is a separate design decision.

Would you like me to open a follow-up issue for that decision?

  • docs(server): name which delegated results run before a restartefb2003

On the other two CodeRabbit items from the review of 0ebbb6a2f3:

  • Outside diff, Orchestrator.ts:6562-6570 (propagate a failed stop instead of returning queued): when the stop cannot be issued, the replacement message is queued and the send reports delivery: "queued", which is what happened. /goal handles a failed stop the same way. Failing the send would leave a queued message the caller was told was rejected.
  • Description check: the reporter asked for this behaviour in the issue ("Could restart, on a driver without native interrupt-and-restart, do exactly that"), and the PR was opened by a maintainer.

Document the freshContext exception.

When freshContext is true, ThreadManagementService.ts converts restart to queue without stopping the active turn. OrchestratorMcpService.ts passes this option through. Qualify the restart guarantee for this input. (raw.githubusercontent.com)

Leaving as is. freshContext turning restart into a queued send is main behaviour for every provider, Codex included, and is not changed here; this paragraph only describes the provider fallback this PR adds.

@juliusmarminge Thanks for clarifying. The freshContext behavior predates this PR and applies across providers. I’ll withdraw the documentation request for this PR.

Document failed stop requests.

If dispatchRunInterrupt fails, Orchestrator.ts keeps the replacement queued and lets the active turn continue. The send reports delivery: "queued". Document this outcome so callers do not assume the turn stopped. (raw.githubusercontent.com)

Leaving as is. A send whose stop could not be issued already answers delivery: "queued" rather than "restarted", so the caller sees from the response that the turn was not stopped; the doc describes the outcomes, not each failure path.

@juliusmarminge Understood. The delivery: "queued" response distinguishes this outcome from "restarted". I won’t insist on the documentation change.

Evidence

Steps on both commits: start a Claude thread running python3 -c 'import time; time.sleep(150)' in the foreground; confirm the command is running; wait 25 seconds; send Stop sleeping and reply with just: restarted through t3_thread_send with mode: "restart".

Environment for both recordings: Linux, isolated real development server, fresh synthetic thread data, light theme, 1280×800 browser viewport. Identical privacy crop; captions identify the actual RPC result and its timing.

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

Not shown:

  • The send used a standalone authenticated MCP driver rather than an agent in another thread; the real t3_thread_send endpoint and provider execution were exercised.
  • Codex control evidence consists of real server transcripts; its UI interaction was not recorded.
  • Held-queue prioritization, replay/idempotency behavior, and maintenance-command exclusions were not exercised by this reproduction.
