Note

Claude writing on behalf of @r3xsean.

Fixes #22531.

A steer sent while Claude was still starting up on the opening prompt was offered with priority now, and Claude Code could run it first: the model answered the steer without the prompt's context, and the prompt ran afterwards as a separate turn.

The Claude adapter now holds a steer until the opening prompt's first model output, then offers it with now as before; held steers go out in the order they were sent. Lifecycle events, init, synthetic notices, and output tagged for another prompt don't release them. Holding returns immediately, so it doesn't block the thread's effect queue. A held steer's PDF budget reservation stays pending until the steer is offered, so a compaction while it waits doesn't drop it from the count.

One behaviour change: a turn that ends without any model output (for example a bare /goal status check) now drops a held steer with a warning log, where previously the steer could run as a separate turn.

Verification

  • Real Claude Code 2.1.305 with Haiku, driven through T3's MCP tools (send a message, then steer straight away). On nightly 0.1.1-nightly.20261020, 3 of 3 steers that reached Claude before the message's API request were answered first without the message's context, and the message ran as a separate run. With this change, 5 of 5 steers that arrived before the message's first model output were held, then answered in order in one run; the provider log shows each one offered with the message's first message_start.
  • ClaudeAdapterV2.test.ts and ClaudeAutomaticDelivery.integration.test.ts on Windows: all pass except 13 that fail the same way on main here (12 attachment tests whose path assertions don't match JSON.stringify's escaped backslashes, and "pins tool search on when the user's Claude settings choose auto"). With those path assertions made backslash-tolerant locally on both, 237 of 239 pass versus 233 of 235 on main, and the same two fail on both: the tool-search test, and a login-error test that the temporary patch itself breaks.
  • tsc-rs --noEmit in apps/server: no errors in server sources.

Walkthrough

ClaudeAdapterV2 now queues steers received before the opening prompt streams. Eligible prompt-associated root output triggers ordered steer delivery. The adapter holds associated PDF reservations until delivery or turn finalization. Tests cover prompt gating, steer ordering, and stream synchronization.

Changes: Startup steering

Layer / File(s)Summary
Queue and release startup steers
apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts
Active turn state tracks prompt streaming and queued steers with their PDF reservations. Eligible root output triggers ordered delivery. Finalization releases reservations for steers that remain queued.
Startup steer regression coverage
apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts
Tests cover startup prompt gating with and without init echoes, steer ordering, held reservations, and prompt-stream synchronization in attachment and wake cases.

Merge Risk: External image Low · up to 6c835

Some startup steers can be lost if an offer fails or the turn ends before model output. The latter limitation is disclosed; contain offer failures before merging or explicitly accept that additional risk.

Security architecture risk: External image Low · up to 4945a

The change affects message ordering within an existing run without adding access or privileges. The main tradeoff is that messages still waiting when the run ends are discarded rather than retried; termination and interruption behavior have less direct verification than normal delivery.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure remains steering of an already active turn through its existing session. The production delta changes delivery timing, not the available callers, credential scope, runtime permissions, or tool authority.

Trust Boundaries and Controls

  • observed — Release requires the current query, a root stream or non-synthetic assistant frame, and compatible prompt identity. Explicitly different prompt identifiers do not release held steers. Untagged output remains acceptable when the session is not known to echo prompt identifiers early, so this is compatibility-based correlation rather than universal cryptographic provenance.

Resilience and Maintainability Implications

  • observed — The production offer implementation places messages into a local queue, and close shuts that queue down before closing the runtime. Stream processing captures failures and finalizes the owning active turn as interrupted or failed, rather than transferring ownership to a replacement query.

Full details: Title check

Explanation

The title states the main change: Claude steers sent while a turn starts are no longer run before the opening prompt. The raw summary shows the adapter now holds steers until the prompt's first model output, which matches the title. The title is a conventional commit, short, and specific. It names the component (server) and the behavior. Note that the title's PR number reference in the objectives is #22552, but that does not affect the title assessment.

Full details: Linked Issues check

Explanation

Issue #22531 requirements are met. ClaudeAdapterV2.ts holds startup steers in heldSteers until a qualifying root prompt frame. Lifecycle frames, init, synthetic output, child output, and output tagged for another prompt do not release them. The adapter offers held steers in FIFO order with priority: "now" and keeps the provider turn running while the prompt is pending. The adapter tests cover startup with and without an init echo, non-release cases, FIFO ordering, and held PDF reservations across compaction.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #22531. Production changes implement startup-steer holding, FIFO release, turn cleanup, and pending PDF reservation handling. Test changes provide deterministic coverage for these behaviors and adjust related attachment and wake-turn setup. No unrelated product behavior appears in the reviewed diff.

Full details: Description check

Explanation

The description explains the startup-steer problem, the change, and the behavior when a turn ends without model output. It links the issue and gives detailed verification results, including test failures also seen on main. The scope section does not document explicit maintainer approval or explain why the fix qualifies without it.

Do not acknowledge a held steer as delivered before release.

ProviderTurnControlService.steer treats a successful session.steerTurn call as success. ClaudeAdapterV2.steerTurn returns successfully after it adds the message to heldSteers. If the turn ends before the first qualifying root model frame, finalization only logs the drop. It does not emit a user-visible notice or retry the steer.

The deliberate-drop intent does not satisfy the existing success path. Either keep the submission pending until release, or propagate the drop so the orchestrator starts the follow-up turn.

Note

Claude writing on behalf of @r3xsean.

Agreed: if the turn ends before the opening prompt produces model output, a held steer is dropped without reaching Claude. Keeping the steer effect pending until release would block Stop and dialog responses behind it in the thread's provider-effect lane. Recovering a drop after the steer has returned needs asynchronous orchestration handling, related to the delivery-recovery work in #22423. I'd suggest leaving that for a follow-up; the limitation is disclosed in the PR and logged as orchestration-v2.claude-held-steers-dropped.

Exercise the repeated started sequence and assert the turn stays running.

The fixture sends only one matching started frame. It does not assert provider-turn state before the opening prompt produces model output, so this test cannot catch a second started event that incorrectly ends the provider turn.

Note

Claude writing on behalf of @r3xsean.

Added a second matching started frame with a distinct UUID and an assertion that the provider turn remains running before model output. This covers repeated lifecycle events while the startup steer is held; it does not replay the issue's separate result-before-restart sequence.

Cover correlated root stream_event release in the startup test.

handleSdkMessage has a separate release path for root stream_event frames, but this test only sends assistant frames before checking the held steer. A regression that releases an unrelated root event or a child event before the prompt’s correlated root event would pass. Add both negative cases, assert that the steer remains held, then send a root stream_event with user_message_uuid: promptUuid and assert release.

The test does not assert that a held steer cannot complete the run before the opening prompt produces eligible output. It only checks harness.offeredMessages and that lastProviderTurn(harness.events).status remains "running". An implementation that emits or accepts a steer result before the prompt answer could still satisfy both assertions because no terminal/result event is injected or checked.

Add a terminal/result frame immediately after the held-steer setup and assert that the run does not complete, or assert the harness run state directly if that is the established helper. Keep the existing stream_event correlation coverage separate from this startup-result case.

Note

Claude writing on behalf of @r3xsean.

Added a child stream_event tagged with the opening prompt's UUID to the existing startup test. Before this, removing the root-only check left the suite passing; the new frame covers that. The attachments test already exercises release on an untagged root stream_event, and the existing unrelated assistant frame exercises the shared correlation check.

I haven't added the suggested result assertion: the opening prompt can legitimately finish before producing model output. Dropping held steers in that case is the limitation discussed in the open thread above.

Also merged main and resolved the test-harness conflict.

Synced from GitHub

Note

Claude writing on behalf of @r3xsean.

Merged main. Since #21358, steerTurn reserves PDF budget per steer, so a held steer now keeps its reservation pending until it's offered: committed and persisted when it goes out, released if the offer fails before it's queued or the steer is dropped. Committing at hold would let a compaction during the hold subtract a PDF that hadn't reached Claude yet; the new held case in "keeps attachment reservations across compaction" covers that. The rewritten attachments test streams the prompt before each steer, so its scenarios run as on main.

Continue releasing held steers after an offer failure.

ClaudeAgentSdkQuerySession.offer can fail with ClaudeAgentSdkQueryRunnerError. The loop removes the first steer before yielding that offer. The failure aborts handleSdkMessage, and query-exit finalization releases remaining held steers without offering or retrying them.

Handle each offer failure inside the loop, continue offering later held steers in order, and propagate the original failure only after the loop completes.

Note

Claude writing on behalf of @r3xsean.

The session interface allows offer to fail with ClaudeAgentSdkQueryRunnerError, but the live implementation never produces it. It's a Queue.offer onto the session's unbounded prompt queue plus a reservation callback and a protocol log whose errors are ignored (ClaudeAdapterV2.ts:957, 1132-1148, 842-854). Queue.offer has no error channel and returns false after shutdown instead of failing. The loop can only stop by interruption, when this query's message handling is torn down, and offering the remaining steers to the same queue then wouldn't deliver them either. Steers still held at that point are released and logged by finalizeActiveTurn, as the PR description notes. The unheld path in steerTurn doesn't retry a failed offer for the same reason, so I've left this as is.

  • test(server): record Claude steering fixture after the prompt streamsaead046
Synced from GitHub

Note

Claude writing on behalf of @r3xsean.

The message_steering/claudeAgent replay hung because its recording sent the steer before the opening prompt reached the model, which is the startup case this PR now holds. The recorder now offers the steer at the prompt's first root model frame, as the adapter does, and the fixture is re-recorded from Claude Code 2.1.312.

Note

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

Partial verification only. I inspected the diff/discussion, installed dependencies, and ran github/main (15fe283272) in a separate worktree, followed by the exact PR head aead046a7ec9693b736a22b5e97fc77f1ab8a649. Only one task dev server ran at a time; main was stopped before starting the head. The verification runs used isolated T3 homes.

I used repository Playwright with /usr/bin/google-chrome, added a project pointing to the real repository through Add project > Local folder, and drove real Codex gpt-6.1-sol turns through the composer and local proxy. No mocks, fixtures, or demo data were used.

  • A steer during a running shell command was accepted through Steer message and answered READY MARBLE STEER-ONE. Persisted events show inputIntent=steer in the same completed run.
  • A rapid steer on the next turn failed with HTTP 400: no active upstream websocket for response.interrupt. This is a Codex/local-proxy finding; I have not established it as a regression from this Claude-only change.
  • A subsequent ordinary follow-up in the same thread completed with MARBLE RECOVERED.
  • Both main and the PR head accepted a real Claude Haiku thread start through the running server, but the provider failed before model output with Not logged in · Please run /login. The web client displayed the authentication error correctly.

real Codex rapid steer and recovery recording

Not verified

The actual changed behavior is unverified: this VM has no authenticated Claude account (claude auth status reports loggedIn: false, authMethod: none). Consequently I could not reproduce the original Claude startup race on main, prove startup hold/release and FIFO on the head, or exercise the no-model-output and attachment-budget cases with a real Claude provider. Codex cannot prove a change confined to ClaudeAdapterV2.

Native desktop, iOS/Android, other operating systems, remote/relay/tunnel, and multi-device behavior were not exercised. No source changes were made. I did not rerun automated checks; the PR status reported 29 successful checks, zero failing, zero pending. Passing CI does not resolve the real-provider verification blocker.
