fix(server): thread waits return when a blocking request needs input - #24712
Read requests, secret-input cards and their owning runs together. Return hasPendingQuestion and the oldest pendingApproval without changing the run status. A queued wait also notices input blocking it on an earlier active run. Finished runs, unrelated later runs and asynchronous message-based questions do not end an active run's wait. Internal settle-after-run waits remain terminal-only.
Thread callers and linked environments return on input by default. External clients retain terminal-only waits unless they set returnOnInput: true, so older CLIs still take their pending-request path and exit with code 2 instead of treating an active run as failed. The updated CLI opts in and preserves the legacy pending-request/recheck fallback when an older server omits the new response fields. Forwarded waits preserve the originating caller's choice across every chunk.
Subscribe to runtime-request updates and filtered secret-input turn-item updates. Wait queries load only pending runtime requests. Background remote followers explicitly request terminal-only waits. Ordinary streaming turn items do not reload the projection; reads fetch only secret-request turn items. Delegated task status reports input only for its own task runs. Existing delegated-completion delivery and restart handling are retained. Responses never expose secret card contents. The wait guidance directs ordinary questions to t3_pending_request, secret cards to thread activity, and asks the user to answer secret cards and approvals in the thread.
Validation on macOS arm64 / Node 26.12.1, head c2480e3321, merged with main 32882540fb:
vp run check:changed 32882540fb --concurrency 1 passes 243 tests in 12 files, formatting, lint, both Knip checks, GraphQL and all 37 affected package typechecks. The SQL turn-item window regression passes on the repository-pinned Node version.
New regressions failed before this follow-up: an old server made the CLI exhaust its wait responses instead of returning needs-input; a legacy external caller incorrectly returned early on an active approval. Terminal-only opt-out also failed before the fix.
Coverage includes current/legacy CLI responses, the later-run completion race, real ThreadManagementService waits for old/updated external clients and thread callers, and explicit wait semantics across a real HTTP peer link.
Existing coverage includes questions, approvals and secret cards on selected/queued runs, secret events after subscription, unrelated/settled requests, delegated tasks, restart continuations and terminal-only internal waits. Event-driven tests use subscriptions/queue delivery; simulated time is used only for timeout assertions.
The measured MCP tool list is 48,130 bytes, 1 byte below main’s 48,131. The current budget test passes. The earlier request for agent-context-increase is superseded by the maintainer’s tool text revision.
The targeted real-model eval node mcp-tool-use/run.ts --case polling-after-async-delegates --samples 1 --out … could not start because ANTHROPIC_API_KEY is absent. The alternative Codex vibeproxy provider is also unconfigured. Real-model evaluation remains unverified; no provider request or client session was exercised.
This changes server/MCP/CLI behavior and has no visual layout change. The change to the default for thread-scoped callers still awaits maintainer review. The MCP eval dry run builds successfully. A real-model run requires the missing eval credentials or proxy configuration.

Macroscope's review found this PR requires human approval — Thread-scoped waits now return on blocking questions, approvals, and secret cards while leaving the run active. This changes existing callers’ default coordination behavior and requires a human product decision.

Summary
Wait outcomes and request evaluation apps/server/src/orchestration-v2/ThreadManagementService.ts, packages/contracts/src/orchestratorMcp.ts, apps/server/src/orchestration-v2/ThreadManagementService.test.ts, apps/server/src/orchestration-v2/ProjectionStore.test.ts, packages/contracts/src/orchestratorMcp.test.ts
Wait results now include pending-question and approval fields. The evaluator checks waiting secret requests and pending live runtime requests for blocking runs, and supports terminal-only waits. Tests cover request ownership, run status, event wake-ups, legacy decoding, and delegated-work outcomes.
MCP task projections include secret-request turn items and limit pending-question and approval checks to active task runs. Thread-wait responses expose the pending-input fields. Tests cover task-owned requests and secret-request wake-ups.
Invocation context, MCP forwarding, and the CLI set input-aware wait behavior. The CLI retains a fallback check for legacy wait responses. Tool guidance and documentation describe pending-input results and timeout behavior.

Explanation
The title names the main change: thread waits (t3_thread_wait) now return when a blocking request, such as a pending question, approval, or secret-input card, needs input. The changeset implements this across the server, MCP, CLI, contracts, and docs. It uses a conventional commit prefix and a single sentence, and it does not describe anything absent from the diff.
Full details: Description check
Explanation
The description covers the problem, the change, scope via a linked issue (#24593), and extensive verification with specific commands, platform, and results. It follows the template's Problem, Change, Scope and approval, and Verification sections. The Scope and approval section links the issue but does not explicitly cite a maintainer approval comment. The description also notes that the default for thread-scoped callers still awaits maintainer review, and the objectives mention an open maintainer decision on that default. The template asks for approval evidence, so this is a gap, but the description is otherwise mostly complete.
Full details: Out of Scope Changes check
Explanation
The changed files support input-aware waits or their compatibility requirements. They include the contract fields (returnOnInput, hasPendingQuestion, pendingApproval), the CLI wait loop and legacy fallback in apps/server/src/cli/thread.ts, ThreadManagementService wait logic and subscriptions, OrchestratorMcpService task-status reporting, peer forwarding of returnOnInput, the RemoteDelegation terminal-only flag, the tool guidance and docs, and the related tests. Secret-card handling is part of blocking-input detection. Delegated task status reports input only for the task's own runs. The agentContextBudget.json change (48131 to 48130) records the measured effect of the revised tool text. The change is small and tied to the tool text update. No unrelated behavior is evident in the summarized changes.
Full details: Linked Issues check
Explanation
[#24593] The reviewed head implements input-aware waiting for thread callers and linked environments. ThreadManagementService.waitForThread settles on a pending runtime request, a live user-input request, an approval, or a waiting secret-request card. Its result reports hasPendingQuestion and pendingApproval and keeps the run's real status. The head also covers queued runs blocked by an earlier run, excludes asynchronous message-based questions, keeps settleAfterRun terminal-only, and updates the CLI, tool guidance, and docs. These parts meet the issue. However, McpInvocationContext.threadWaitReturnsOnInput returns false for external MCP clients unless they pass returnOnInput: true. The issue states expected t3_thread_wait behavior without a scope limit and proposes 'No opt-in flag'. For external callers, an active run that waits on input still returns only at terminal state or timeout by default. The PR description calls this a deliberate default and says maintainer review is pending. That reason covers older CLIs. It does not change the issue requirement. This conclusion is unchanged from the previous review, because the external-caller default has not changed in the new commits.
Resolution
Make t3_thread_wait return on blocking input by default for external callers. Change threadWaitReturnsOnInput so an absent returnOnInput yields true for external scopes too. Keep terminal-only behavior for internal waits such as settleAfterRun and for background remote followers that set returnOnInput: false. Keep the legacy CLI fallback for older servers. Update the external-caller default tests in OrchestratorMcpService.test.ts, PeerForwarding.test.ts, and the related documentation. If maintainers instead accept an opt-in default for external clients, the issue owner must record that scope change on #24593. The assessment then needs re-evaluation.

971-982: Trivial · Performance & Scalability · Low value
Skip terminal-only runtime-request wake-ups.
settleAfterRun starts only for a shell activeRunId, whose statuses are preparing, starting, or running. Therefore, its terminal-only wait normally subscribes while the selected run is active. A runtime-request.updated event then rereads runs, nodes, and runtimeRequests, although terminal-only settlement does not inspect pending requests.
The wait can last until the run completes or the 24-hour timeout. Runtime-request events occur during request lifecycle changes, but the source does not establish a high per-thread frequency or a material production cost. Treat this as an optional performance refactor, not a high-reward issue.
The terminal-only projection read also requests nodes and runtimeRequests. Remove those fields only after updating the projection type used by outcome to support a runs-only read. Do not add omitSettledLeafNodes without an established guarantee that settled leaf nodes cannot own pending requests.

Thanks, this matches the design proposed in #24593.
One suggestion: keep WAIT_SLICE_MS at 15 s in apps/server/src/cli/thread.ts. With this fix the wait returns early on a question or approval, so the step length no longer affects how soon the CLI notices one. Raising it to 10 min changes the CLI's default behaviour, and Macroscope flagged that change for human approval. It also makes each call a single 10-minute request, which a tunnel or proxy can drop when the connection stays idle (see #18540). With 15 s the PR stays focused on the issue.
A small nit: two CLI tests still script t3_thread_read responses, but waitForRun no longer calls that tool.
@nateEc, kept your implementation and commits, merged current main, and pushed the focused follow-up at 906caf33f5.
kept cli wait slices at 15 seconds and removed unused read mocks.
skipped request reads and wakeups for terminal-only settlement waits.
fixed a reordered queued run missing a higher-ordinal active blocker, with a regression that failed before the fix.
covered newly arriving native questions and approvals, preserved main's next guidance, and clarified that approval responses belong in the human client.
verification: main's real codex native question and command approval both left a 2-second mcp wait timing out. on this head, the same provider scenarios return timedOut: false, unchanged running status, and the correct question/approval fields. both production cli --wait calls exit 2. answering the question through mcp and approving the harmless command in the web client both resume to completion, clear the request fields, and a later cli turn completes with exit 0.
blacksmith-check ran vp run check:changed github/main: format, lint, both knip checks, graphql generation, 30 affected package typechecks and 61 tests across 5 existing files passed. ci completed with no failures; coderabbit reported no actionable findings. two independent sol reviews found no code issues on this head. macroscope correctness passed; its neutral approvability result leaves the runtime-policy decision for maria.
runtime transcript. live verification used linux, codex gpt-6.1-sol, and the configured responses proxy. other providers, separate desktop/mobile clients, and remote/relay/tunnel connections remain unverified. no ui code changed. the captures show the existing request ui; earlier turns differ after restarting on this head.
Thanks for this fix. One more blocking case does not go through runtimeRequests, so the new wait does not return for it.
An agent can call request_secret. T3 Code stores that card as a secret_request turn item, not as a runtime request. The thread shell already treats a waiting secret_request on a live run as blocking input (apps/server/src/orchestration-v2/ProjectionStore.ts:1553-1563 and :1600-1610 at 3f9448747b), but the MCP side reads only runtimeRequests.
At head 906caf33f5, the new outcome helper in ThreadManagementService.waitForThread loops over projection.runtimeRequests only, and the wait stream listens to run.updated, thread.deleted and runtime-request.updated. The diff has no secret_request and no turn-item.updated.
I checked this with a focused service-level test on 906caf33f5 (a test reproduction, no live run or provider). With a waiting secret_request on a running child, OrchestratorMcpService.waitForThread (the service behind t3_thread_wait) returned timedOut: true and hasPendingQuestion: false after the test clock passed the 60 s limit, and taskStatus also returned hasPendingQuestion: false. In the same fixture, a pending user_input runtime request ended the wait at once with hasPendingQuestion: true.
Would a follow-up after this lands be welcome? It would count a waiting secret_request on a live run in the same check, listen to turn-item.updated, and never return the secret value. Settle handling is out of scope (#18606 already checks secret_request there).
Verified the secret-input gap reported in #24712 (comment) and included it in 5dafde2, after syncing main. It belongs to the same pending-input wait behavior, so a separate follow-up PR is no longer needed.
Waiting secret cards now end waitForThread, including cards emitted after subscription, and taskStatus reports them for the task's own active runs. Ordinary turn-item streaming does not cause extra projection reads. Terminal-only waits, resolved cards and unrelated/finished runs retain their existing behavior. Only the existing pending-question boolean is returned; secret contents and card metadata are not exposed. Settlement behavior is unchanged.
Before the fix: four new regressions failed with timed-out waits or hasPendingQuestion: false. After the fix: vp run check:changed passed all 69 tests in five files, plus format, lint, both knip passes, GraphQL generation and affected-package typechecks. The PR description now includes the service-level execution results and validation scope.

verified unchanged head 1c603f46116a38d96b33762178de686a8ca63214 on this linux boat vm. installed and ran github/main (2a738273e7) in a separate worktree first, stopped it, then installed and ran the exact pr head. one dev server at a time, isolated state, real git project created through the app, playwright with /usr/bin/google-chrome, real codex gpt-6.1-sol through the local proxy. no replay, mocks, fixtures, or demo data.
main: native question, command approval, and secret card all left t3_thread_wait timing out while input was visibly pending.
pr: the same three blockers return timedOut: false with the correct question/approval fields and unchanged running status. an arriving secret card woke an already-active wait.
client responses resume correctly: choosing blue, approving touch approval-proof.txt, and declining secret cards all completed their provider turns.
nearby behavior: a queued run reports the blocking question and completes after the answer. an older completed run ignores a later approval. cli --wait exits 2 for secret input and 0 for ordinary completion.
delegated codex child: delegate_task in wait mode returned hasPendingQuestion: true, waitTimedOut: false, status running when its secret card arrived. declining in the child client completed it.
blacksmith-check ran vp run check:changed be2ea30d2b269f1526be3fd556bc5380b4dc01b3: format, lint, both knip passes, graphql, 32 package typechecks, and 153 tests in nine files passed. no source changes or pushes were needed.
other providers, native desktop and ios/android, macos/windows, remote/relay/tunnel connections, mixed-version peers, and every internal restart/terminal-only/ownership permutation were not exercised live. existing scoped tests cover those service-level permutations. no actual secret was submitted or consumed by an external service. these captures show existing ui; the pr changes server/mcp/cli behavior.
merged github/main (d2c25950b4) into the contributor head with merge commit a3b52973e0, pushed without force. no code changes beyond the merge.
conflict: agentContextBudget.json takes main's values, with mcpToolListJsonBytes set to the measured 48,129 (2 under main).
the open CodeRabbit threads are both outdated: the budget value is re-measured above, and the RemoteDelegation.ts follower already sends returnOnInput: false (from bfb11f6e94).
vp run check:changed on a remote box: format, lint, knip, graphql and typecheck pass; 226 of 227 tests pass. The one failure, ProjectionStore.test.ts "reads a fixed SQL turn-item window", is main's test and needs Node 26's statement.stat; the box runs Node 24.
unverified: the mcp-tool-use evals were not rerun on the shorter t3_thread_wait text from the earlier pass.
Addressed all three outside-diff findings from review 5812778367 in b3727bc:
Old CLI → new server: external callers keep terminal-only semantics by default. Updated clients explicitly opt in with returnOnInput; thread callers retain input-aware defaults. The choice survives HTTP peer forwarding.
New CLI → old server: the CLI preserves an omitted input flag during decoding and falls back to the legacy pending-request check plus a final wait recheck, so a later run's request cannot replace an already completed result.
Wait guidance now distinguishes ordinary questions, secret cards and approvals, including where the user answers them.
The compatibility regressions failed before the fix. vp run check:changed --concurrency 1 now passes all 225 tests in 12 files and all 36 affected-package typechecks, plus formatting/lint/Knip/GraphQL checks.
The measured tool list is 48,358 bytes (+239 versus main). A maintainer must add agent-context-increase: both available credentials lack label-write permission. The targeted real-model eval also remains blocked by missing ANTHROPIC_API_KEY / unconfigured Codex proxy. The PR body records these limits; I am not treating the automated checks as approval of the behavior change.

Narrow the runtimeRequests read to pending requests.
filter limits turnItems and nodes, but it does not limit runtimeRequests. outcome uses only requests with status === "pending". Every wait wake-up reads all historical runtime-request payloads for the thread. The runtimeRequests wake streams make these reads more frequent. Add runtimeRequestStatuses to the filter. ProjectionStore already supports it for the non-windowed read.
Confirm that "pending" is a valid value for runtimeRequestStatuses before you apply this change.

Make `t3_thread_wait` return on blocking input by default for external callers
too. Keep terminal-only behavior only for internal waits that require
settlement, such as `settleAfterRun`, and for background remote followers that
set `returnOnInput: false`. Keep the legacy CLI fallback for older servers.
Update the external-caller default tests in `OrchestratorMcpService.test.ts`,
`PeerForwarding.test.ts`, and `McpInvocationContext` accordingly. If maintainers
accept the opt-in default for external clients, the issue owner must record that
scope change explicitly. The assessment then needs re-evaluation.

Linked peers arrive as client callers, so an older peer's task follower,
which sends no returnOnInput, would get an input-aware wait and re-call it
at once while the remote thread waits for an answer. Client callers now
opt in; PeerForwarding already sends the caller's resolved choice.
Also: the CLI's follow-wakes loop reports needs_input when the woken run
asks for an answer, and t3_thread_wait keeps main's description.
AI-assisted; verified with the tests and tools listed above.
ThreadManagementService.waitForThread returned early on pending input
unless a caller passed terminalOnly. ScheduledTaskService.recordRunFailure
did not, so a run that asked a question ended its monitoring and a later
failure left the task marked succeeded. The service now waits for a
terminal run unless the caller sets returnOnInput, which only the MCP
thread wait does.
AI-assisted; verified with the tests and tools listed above.
…argument
The returnOnInput argument grew the advertised MCP tool list past main's
agent context budget. Waits now return on blocking input for thread
callers only; the CLI, other MCP clients and linked peers' followers keep
terminal-only waits, so the CLI and peer plumbing for the flag is reverted.

Real dev servers, Chromium web client, 1280×800, light theme, fresh unseeded homes and identical synthetic state. Replay agents made real MCP calls. Steps: unanswered existing question → queued run blocked by that question → arriving question → approval → delegate secret request → direct secret wait → unrelated-run metadata → outside-MCP and linked-peer terminal-only controls → real CLI waiting/completion. Thread waits used 15-second budgets; external controls used three seconds.
Additional paired captures for arriving questions, approvals, direct secret waits, outside-MCP, linked-peer and CLI controls are in the complete Evidence section. Outside-MCP and linked-peer callers timed out while input remained pending and returned interrupted only after the run ended. The real CLI returned waiting/exit 2 after its normal slice and completed/exit 0 for completed work. The unrelated-approval control returned pendingApproval=null on both commits; no difference is claimed for it.
Forwarding between two separately running linked environments was not exercised; linked-peer authentication and the changed terminal-only wait default were exercised with real peerLink credentials against each server.

bugfix
A thread waiting on live user input or approval keeps its run active, so
t3_thread_waitpreviously slept until timeout even when a person needed to answer. Secret-input cards have the same problem because they are stored as turn items rather than runtime requests. Fixes https://git.cafe/pingdotgg/t3code/issues/24593.Read requests, secret-input cards and their owning runs together. Return
hasPendingQuestionand the oldestpendingApprovalwithout changing the run status. A queued wait also notices input blocking it on an earlier active run. Finished runs, unrelated later runs and asynchronous message-based questions do not end an active run's wait. Internal settle-after-run waits remain terminal-only.Thread callers and linked environments return on input by default. External clients retain terminal-only waits unless they set
returnOnInput: true, so older CLIs still take their pending-request path and exit with code 2 instead of treating an active run as failed. The updated CLI opts in and preserves the legacy pending-request/recheck fallback when an older server omits the new response fields. Forwarded waits preserve the originating caller's choice across every chunk.Subscribe to runtime-request updates and filtered secret-input turn-item updates. Wait queries load only pending runtime requests. Background remote followers explicitly request terminal-only waits. Ordinary streaming turn items do not reload the projection; reads fetch only secret-request turn items. Delegated task status reports input only for its own task runs. Existing delegated-completion delivery and restart handling are retained. Responses never expose secret card contents. The wait guidance directs ordinary questions to
t3_pending_request, secret cards to thread activity, and asks the user to answer secret cards and approvals in the thread.Validation on macOS arm64 / Node 26.12.1, head
