fix(opencode): a failed steer no longer leaves the turn running forever - #24701
With an OpenCode 1.x server, a steer whose prompt request fails can leave the turn running for good. The thread keeps showing Working after OpenCode has finished and gone idle.
Steering marks the turn's prompt admission as pending before it sends promptAsync. While admission is pending, the adapter holds session.idle and session.status: idle, because an idle that arrives before OpenCode picks up a new prompt can be stale. A completed assistant message releases the hold. When the steer request fails, nothing clears the pending flag, and OpenCode never received the prompt, so no user message for it arrives. If the turn's last assistant message had already completed when the steer started, nothing else releases the hold either. Every later idle is held, and the turn stays running.
The window is narrow. Against OpenCode 1.19.4, idle arrives about 4 ms after the last assistant message completes. A steer that fails while the agent is still generating does not hang the turn, because the assistant completion that follows releases the hold.
Expected: a rejected steer is reported, and the turn ends when the session goes idle, as it would without the steer.
Change
When the steer's prompt request fails and its admission is still current, steerTurn reconciles the native session's current status. Idle completes the turn; busy releases admission so a later idle can complete it. A status sequence detects idle, busy, or retry events received during the status read and retries that read before accepting a potentially stale result.
The current-admission check skips the cases another path already owns: a Stop, which clears admission itself, a newer steer, and a native command whose failure has already failed the turn. The steer error still reaches the caller as before.
The OpenCode 2 adapter already does this for a rejected steer: it drops the steer and ends the turn if the session has settled.
Scope and approval
No issue, and no maintainer has agreed to this yet; it awaits maintainer review. It is a small fix for a confirmed bug in one adapter method, and it changes nothing for steers that succeed, for starting a turn, or for OpenCode 2 servers. One choice for maintainers to confirm: when the session is already idle, a rejected steer ends the turn as completed, as the OpenCode 2 adapter does, rather than failed.
Verification
This head, e9fc9f7fb6. The maintainer's captures further down, from "Latest takeover head" on, were taken on earlier heads, before main was merged and before this fix; every capture in this section names the commit it ran on. It is 1915c8ce88 with main 9359081c24 merged in (9193cd76b5, no conflicts) and one commit: only an HTTP error reply or a connection that never opened counts as a rejected steer. After any other failure OpenCode may have taken the steer, or an earlier attempt of it (T3 retries a failed steer), so the turn waits for that steer's output, or Stop, instead of completing on the next idle and dropping the answer. This covers the second item of the Not checked list further down.
To see it on Linux web: point T3 at opencode serve as an external server, start a turn that runs a long shell command, stop OpenCode, steer, start OpenCode again on the same port. On main the thread stays Working after OpenCode is back and idle; on this head the turn ends when OpenCode is back (records in details).
I ran a real opencode serve 1.19.5 in a test T3 server ("Test machine") with a real model (gpt-6-luna through my gateway), input in the Browser panel, main first. A stand-in proxy sat between T3 and OpenCode. It holds OpenCode's idle events for 45 seconds so a steer can be sent by hand after the reply, and changes one thing per run: it answers every steer attempt for 3 seconds with 503 (T3 retries a failed steer up to 5 times), or it passes the first steer to OpenCode and withholds OpenCode's reply from T3. Everything else passes through; it logs no headers.

Head e9fc9f7: the steer's answer is shown and the turn finished
On the head, T3 then resends the refused message as a new turn, which the proxy still refuses (Provider error). With a real model OpenCode is already busy when T3 reads its status after a withheld reply, so this run cannot show the short window in which 9193cd76b5 dropped a steer's answer; the scripted run in the details block forces that window, and the adapter tests cover it.
Tests on e9fc9f7fb6 pass (adapter suite and vp run check:changed); the new regression cases fail on the code before this commit (details).
Not checked on this head: desktop and mobile clients, and 1915c8ce88 on its own (its web client never connected to its test server on my test host).
Tests, scripted runs and records
Tests on e9fc9f7fb6: the adapter suite (64) and vp run check:changed pass. "keeps the turn for a steer whose reply was lost until its output lands" fails with 9193cd76b5's adapter.ts (expected [] to include 'README covered'); its case "even after a retry is rejected" also fails with the previous candidate's adapter.ts; both pass here. With main's adapter.ts, 7 of the 8 rejected-steer cases fail.
In the withheld-reply runs T3 also retried the steer and the retry reached OpenCode, on both revisions (proxy records below).
A scripted run with a local model (no account) and the proxy in a third mode: every steer attempt for 3 seconds gets its connection closed with no reply, and only the first is delivered to OpenCode 2 seconds later, so OpenCode is idle when T3 reads its status. This forces the window in which this PR's code before this commit (9193cd76b5) dropped the steer's answer.

Latest takeover head 6dd5df611d: blacksmith vp run check:changed da8cc591dadd75819ae62961da4a882767efb145 passes format, lint, knip, 10 affected package typechecks, and 45 tests. Seven regression cases cover idle timing, stale idle followed by busy, idle or busy during a status read, and repeated user updates. The new busy-during-status case fails before the fix by completing prematurely. All 29 CI checks pass on 6dd5df611d. Both independent final-head reviews approve, and CodeRabbit reports no new actionable findings.
The original author's verification follows. Latest web evidence is appended below and in the takeover comment; desktop/mobile and a live model service were not rerun during takeover.
A new test in adapter.test.ts starts a turn, admits its prompt, then steers with a promptAsync that rejects. It runs twice: with the idle arriving while the steer request is in flight, and with the idle arriving after the steer has failed. Both cases assert that the steer fails and the turn ends completed.
On the base commit both cases fail with the turn still running.
On this branch both cases pass.
vp test run src/server/adapter.test.ts in packages/provider-opencode: 33 of 33 pass.
vp run check:changed main: format, lint, knip, typecheck and tests pass.
In the web client, against OpenCode 1.19.4 with a scripted OpenAI-compatible model behind it, I put a small proxy between T3 Code and OpenCode. It answers each session's second prompt_async with a 503 and holds OpenCode's idle events for 60 seconds, so the window above is wide enough to steer into by hand. Steps: send "Count slowly to 15.", queue a follow-up while it runs, wait for the count to finish, click Steer on the queued message, then wait past the held idle.
On the base commit the steer fails and the thread keeps working. Its provider turn was still running when I stopped the server, about 100 seconds after OpenCode's idle reached T3 Code.
On this branch the provider turn completes at the moment the held idle reaches T3 Code.
The same steps on the Android app (Debug build, Android 16 emulator), steering from the queue sheet, give the same result. On base the provider turn was still running about 70 seconds after the held idle reached T3 Code. On this branch it completed when the idle arrived.
The iOS app (Debug build, iOS 26.5 simulator) matches: on base the provider turn was still running about 130 seconds after the held idle arrived, and on this branch it completed when the idle arrived.
The desktop app on Linux (dev build) matches: on base the provider turn was still running about 130 seconds after the held idle arrived, and on this branch it completed when the idle arrived.
Not checked:
Production builds. Every client run above used a dev or Debug build.
The case where OpenCode accepted the prompt but the request still failed on our side, such as a dropped connection after the server took it. The turn may then complete before the steer's reply arrives. Turn start already treats a failed prompt request as not admitted and fails the turn.
A steer whose prompt request failed kept the turn's admission pending, so
every later idle was held for a prompt OpenCode never received. Clear the
admission on failure and end the turn if the session already went idle.

Macroscope's review found this PR approvable — This narrowly scoped fix clears stale steer admission state after a rejected OpenCode prompt and adds coverage for idle events arriving before or after the rejection. Existing successful steer behavior and unrelated turn paths remain unchanged.

The adapter tracks status events during prompt admission and retries reconciliation when an event arrives during a status query. Status reads time out after ten seconds. Failed steering submissions trigger reconciliation only if the turn and captured admission generation remain current.
Changes: Steering rejection handling
Layer / File(s)
Summary
Admission reconciliation on rejection packages/provider-opencode/src/server/adapter.ts, packages/provider-opencode/src/server/adapter.test.ts
The adapter tracks status events during admission and retries reconciliation if the sequence changes during a status query. A status read that exceeds ten seconds returns unknown. Failed steering submissions trigger reconciliation only when the turn and captured admission generation remain current. Tests cover seven steering timing scenarios and a pending status read.
Rejected steers now recover instead of leaving the turn running. However, if a steer is accepted but its response is lost, the turn can be marked complete early and the assistant's reply dropped. Resolve this before merging or explicitly accept the risk.

Full details: Description check
Explanation
The description follows the template closely. It has a clear Problem section (a rejected steer leaves the turn Working after OpenCode goes idle), a detailed Change section (reconcile native session status after a failed steer while admission is current, with a status sequence and retry), a Scope section that explains why no issue is linked and notes that no maintainer has agreed yet, and an extensive Verification section. The Verification section lists the commits tested, the unit test results (33 and 64 adapter tests appear in different places, and the counts conflict with the takeover note of 45 and 44), live and scripted runs with records, and a Not checked list. Weaknesses: the template asks for a Conventional Commit title, which is not part of the description body and cannot be judged here. The description is long and spreads verification across several commit heads, so a reviewer must work to follow which results apply to the final head. It also has no explicit link to a maintainer request, which the Scope section acknowledges. These are gaps in precision rather than missing required sections, so the check passes.

thanks @only21mil. your regression correctly identified rejected steering leaving admission pending. i kept your commit, merged current main, and pushed the follow-up to this branch (51d8f1a955).
the fix now reuses current-status reconciliation rather than completing from a historical idle. busy stays running; idle completes; failed status reads retry through the existing path. an idle sequence prevents losing an idle received during a busy status read while preserving successful admission's historical idle flag. this also addresses the CodeRabbit finding on 784e36bf.

the original two cases fail on current main (running instead of completed). stale-idle-then-busy fails on the original implementation. gated idle-during-status and repeated-user-update regressions fail before their respective fixes.

thanks @only21mil. your regression identified the pending admission left by a rejected steer. this branch already had maria's status-reconciliation follow-up, so i preserved that implementation and all contributor commits. this pass merges current main and its ci repair, then fixes the new busy-during-status-read finding in 6dd5df611d. the final diff remains two files, with seven regression cases.
current-status reconciliation keeps a busy session running despite an older idle. one status sequence preserves idle, busy, and retry events received during a status read. if it changes, reconciliation reads status again before accepting either result. this prevents a stale idle response from completing a still-busy turn.
verification:
reproduced both original regressions on current main through blacksmith: running instead of completed.

found and fixed a live recovery stall in 1915c8ce88. the status request used after rejected steering could hang during opencode restart, leaving admission pending even after the native session became idle. it now times out after 10 seconds, cancels the HTTP request, and retries through the existing reconciliation loop. pushed without force to this contributor head and origin/maria/takeover-pr-24701-status-timeout.
ran github/main (6575ce3250) in ../main after vp i, stopped it by its captured PID, then ran the exact original PR head (6dd5df611d) after vp i. only one dev server ran at a time.
drove the real web client with repository Playwright and /usr/bin/google-chrome. created a project pointing at a real git repo and created threads through the app. opencode 1.19.5 used the live local proxy with gpt-6.1-sol. no mocks, fixtures, demo provider, scripted model, or rejecting transport proxy.
started a real shell sleep, sent a successful steer, killed only the task-owned external opencode process, and sent another steer through the composer. the request failed with ECONNREFUSED. restarted opencode on the same port and confirmed native idle. main stayed running; the original PR also stayed working because its status HTTP request never returned. this is a real transport-failure reproduction, broader than the original narrow timing window.
repeated the flow with the fix: the original turn became completed, working disappeared, and send returned. a new turn ran pwd and replied FOLLOWUP_OK. stopping the orphaned shell task also worked.
real codex gpt-6.1-sol turns on the fixed build completed normally (CODEX_OK), accepted steering (CODEX_STEER_OK), and honored stop (interrupted persisted).

Do not complete an ambiguously accepted steer from idle status.
OpenCode 1.19.5 forks promptSvc.prompt(...) and returns 204 No Content without waiting for prompt execution. A transport error or timeout can therefore reach the adapter after OpenCode accepted the steer but before the session becomes busy.
The adapter sends every promptAsync error to reconciliation. A stable idle result then completes the turn and causes later assistant output to be ignored. Distinguish confirmed rejection from uncertain transport failure before treating idle as terminal. Add a regression case for an accepted prompt whose response is lost.

2172 - 2173:
Update the idle-status handling in the turn reconciliation flow so it does not
call finalizeTurn with “completed” when a promptAsync error may be an uncertain
transport failure after OpenCode accepted the steer; only treat idle as terminal
after confirmed rejection. Add a regression case where an accepted prompt’s
response is lost and later assistant output is still processed.

@maria-rcks, about the open CodeRabbit item (review 5714853808): we checked whether a small fix could close it. We don't think one exists without a protocol choice, so here is the analysis. The choice is yours.
Why the adapter can't tell. In OpenCode 1.19.5, prompt_async forks promptSvc.prompt and returns 204 right away (server/routes/instance/httpapi/handlers/session.ts:311-328). The prompt saves the user message only after it resolves the agent, the model and the file parts (session/prompt.ts:1053-1057). So once a 204 is lost, neither session.status nor a lookup of our own messageID can tell "rejected" from "accepted, not saved yet". At 1915c8ce88, every steer error goes to reconciliation (adapter.ts:3418-3422), and an idle read completes the turn (L2172-2173). If that read happens before OpenCode marks the session busy, the steer's output arrives after the turn has ended and is dropped. On main, the same case never completes: the steer's user message sets admissionMessageObserved but not admissionAccepted (L321), so admission holds forever.
Options
Classify the steer error. Two errors confirm a rejection: a connect failure where nothing was sent (ECONNREFUSED, as in your restart reproduction) and an HTTP error response from OpenCode. Both keep today's idle completion. Any other failure (a reset, timeout or abort after the request was written) is ambiguous. An ambiguous failure never completes the turn from idle; the turn waits for the steer's own user message or for busy, and Stop still ends it. The steer's own user message would also count as acceptance. Cost: a short list of undici error codes to maintain, and a steer that OpenCode really dropped after an ambiguous error shows as running until Stop.
Recover late output. Keep idle completion. When a user message with a finished steer's messageID arrives, open a new provider turn for it, as createChildTurn does for subagent sessions. Nothing is lost, but this needs an orchestration decision about turns the provider starts.
Land as is. State the limit in the body and track the rest separately. This PR fixes the rejected-steer and refused-connection cases. For an accepted steer whose response is lost, it trades main's endless run for possibly dropped output.
Recommendation: 1. A running turn that Stop can always end (#27252) is easier to recover from than output that disappears without notice. The confirmed-rejection path you verified live stays as it is. It needs a regression case where the steer request fails after OpenCode accepted it and the later output still lands in the turn. It also needs a live run in which a proxy drops the response after the request reaches OpenCode.
If you choose 1 or 2, we can build it as an offer branch that fast-forwards this head, or you can take it. We won't push to the branch either way.
…Code answers
Only an HTTP error reply or a connection that never opened proves OpenCode
rejected a steer. Any other failure may follow a steer OpenCode took, so the
turn now waits for that steer's message, or Stop, instead of completing on
the next idle and dropping its output.

Problem
With an OpenCode 1.x server, a steer whose prompt request fails can leave the turn running for good. The thread keeps showing Working after OpenCode has finished and gone idle.
Steering marks the turn's prompt admission as pending before it sends
promptAsync. While admission is pending, the adapter holdssession.idleandsession.status: idle, because an idle that arrives before OpenCode picks up a new prompt can be stale. A completed assistant message releases the hold. When the steer request fails, nothing clears the pending flag, and OpenCode never received the prompt, so no user message for it arrives. If the turn's last assistant message had already completed when the steer started, nothing else releases the hold either. Every later idle is held, and the turn staysrunning.The window is narrow. Against OpenCode 1.19.4, idle arrives about 4 ms after the last assistant message completes. A steer that fails while the agent is still generating does not hang the turn, because the assistant completion that follows releases the hold.
Expected: a rejected steer is reported, and the turn ends when the session goes idle, as it would without the steer.
Change
When the steer's prompt request fails and its admission is still current,
steerTurnreconciles the native session's current status. Idle completes the turn; busy releases admission so a later idle can complete it. A status sequence detects idle, busy, or retry events received during the status read and retries that read before accepting a potentially stale result.The current-admission check skips the cases another path already owns: a Stop, which clears admission itself, a newer steer, and a native command whose failure has already failed the turn. The steer error still reaches the caller as before.
The OpenCode 2 adapter already does this for a rejected steer: it drops the steer and ends the turn if the session has settled.
Scope and approval
No issue, and no maintainer has agreed to this yet; it awaits maintainer review. It is a small fix for a confirmed bug in one adapter method, and it changes nothing for steers that succeed, for starting a turn, or for OpenCode 2 servers. One choice for maintainers to confirm: when the session is already idle, a rejected steer ends the turn as
completed, as the OpenCode 2 adapter does, rather thanfailed.Verification
This head,
e9fc9f7fb6. The maintainer's captures further down, from "Latest takeover head" on, were taken on earlier heads, before main was merged and before this fix; every capture in this section names the commit it ran on. It is1915c8ce88with main9359081c24merged in (9193cd76b5, no conflicts) and one commit: only an HTTP error reply or a connection that never opened counts as a rejected steer. After any other failure OpenCode may have taken the steer, or an earlier attempt of it (T3 retries a failed steer), so the turn waits for that steer's output, or Stop, instead of completing on the next idle and dropping the answer. This covers the second item of the Not checked list further down.To see it on Linux web: point T3 at
opencode serveas an external server, start a turn that runs a long shell command, stop OpenCode, steer, start OpenCode again on the same port. On main the thread stays Working after OpenCode is back and idle; on this head the turn ends when OpenCode is back (records in details).I ran a real
opencode serve1.19.5 in a test T3 server ("Test machine") with a real model (gpt-6-lunathrough my gateway), input in the Browser panel, main first. A stand-in proxy sat between T3 and OpenCode. It holds OpenCode's idle events for 45 seconds so a steer can be sent by hand after the reply, and changes one thing per run: it answers every steer attempt for 3 seconds with 503 (T3 retries a failed steer up to 5 times), or it passes the first steer to OpenCode and withholds OpenCode's reply from T3. Everything else passes through; it logs no headers.9359081c24e9fc9f7fb6On the head, T3 then resends the refused message as a new turn, which the proxy still refuses (Provider error). With a real model OpenCode is already busy when T3 reads its status after a withheld reply, so this run cannot show the short window in which

Tests on

"keeps the turn for a steer whose reply was lost until its output lands" fails with9193cd76b5'sadapter.ts(expected [] to include 'README covered'); its case "even after a retry is rejected" also fails with the previous candidate'sadapter.ts; both pass here. With main'sadapter.ts, 7 of the 8 rejected-steer cases fail.In the withheld-reply runs T3 also retried the steer and the retry reached OpenCode, on both revisions (proxy records below).
A scripted run with a local model (no account) and the proxy in a third mode: every steer attempt for 3 seconds gets its connection closed with no reply, and only the first is delivered to OpenCode 2 seconds later, so OpenCode is idle when T3 reads its status. This forces the window in which this PR's code before this commit (

A new test in

It runs twice: with the idle arriving while the steer request is in flight, and with the idle arriving after the steer has failed. Both cases assert that the steer fails and the turn endscompleted.On the base commit both cases fail with the turn still
running.On this branch both cases pass.

It answers each session's second
prompt_asyncwith a 503 and holds OpenCode's idle events for 60 seconds, so the window above is wide enough to steer into by hand. Steps: send "Count slowly to 15.", queue a follow-up while it runs, wait for the count to finish, click Steer on the queued message, then wait past the held idle.On the base commit the steer fails and the thread keeps working. Its provider turn was still
runningwhen I stopped the server, about 100 seconds after OpenCode's idle reached T3 Code.On this branch the provider turn completes at the moment the held idle reaches T3 Code.
