fix(agent): report a timed-out turn as a failure and bound the host wait by hunglp6d · Pull Request #9056 · NVIDIA/NemoClaw

hunglp6d · 2026-08-13T23:09:36Z

Summary

$$nemoclaw <name> agent reported success when the agent turn's deadline fired without producing a result: both transports exited 0, so a CI job or an evaluation harness recorded a timed-out turn as a pass. The host command also had no deadline of its own, so a turn that stopped answering held the host until the in-sandbox deadline fired. This change bounds the host command when the caller passes --timeout, classifies a timed-out turn as a failure with exit 1, and documents both deadlines and the commands that raise them.

Related Issue

Follow-up to #9036, which closed #8723. #9036 fixed the cancellation half of that report. The timeout half still reproduced after it: on 0810a95ecd a timed-out turn exits 0 on both transports, and no --timeout reaches the host transport.

What #9036 already fixed, and is not repeated here

Host termination reaches OpenShell. runAgentDispatch replaced the synchronous transports so a host SIGTERM is forwarded to the OpenShell child, and the command returns 130 or 143.
One combined 64 MiB capture bound across stdout and stderr.
NEMOCLAW_AGENT_TIMEOUT is documented as a build-time setting.

This pull request leaves all of that unchanged. It adds no signal handling, no capture logic, and no second dispatch runner; both transports keep calling runAgentDispatch.

What #9036 did not cover

#8723 report	State on `0810a95ecd`	This change
the turn ran past its deadline	the host wait is still unbounded	`--timeout N` also bounds the host at `N + 30`
no result reached the caller	both transports still exit `0`	a timed-out turn exits `1` with guidance
the sandbox kept working after the host was signalled	fixed by #9036	unchanged
no recovery guidance	the two deadline keys were undocumented	documented, and named in the failure text

Changes

Read the --timeout value out of the forwarded openclaw agent argv and pass value + 30 to openshell sandbox exec on both transports. --timeout 0, an unreadable value, or an argv without --timeout leaves the host wait unbounded, so no caller loses an unbounded turn it did not ask to bound.
Add timeoutPhase to the OpenClaw run-metadata markers that already classify an incomplete turn, so the JSON transport reports a timed-out turn as a failure. Presence is the marker rather than a fixed set of phase values, so a phase added upstream keeps classifying.
Match OpenClaw's timeout report in the captured output on the non-JSON transport, which has no structured payload to read. This mirrors the existing embedded-fallback branch in the same file and carries the same documented removal condition.
Write deadline-specific guidance that names sessions export, shields down, and config set --restart, and states which key each deadline lives in.
Document the host bound, the new exit status, the timeoutPhase marker, and the difference between the two deadline keys.

The 30-second buffer is a choice, not a derivation, and its constant records the measurements behind it. The in-sandbox turn owns the deadline and answers first while it can still write to stderr, so the host bound catches only a turn that stops answering. Nine aborted runs finished between 0.1 s and 20.8 s after their deadline, and four recorded no finish at all, so no measurement establishes an upper bound. passthrough-dispatch.test.ts protects the parser, the buffer, and both classifiers.

Why the exit-status change is called out

A command that exited 0 on a timed-out turn now exits 1. That is a public contract change, and it is the change the report asks for. #8796 and #7104 are the same family: a dispatch that produced no result still reported success. If the maintainers prefer a different code, or prefer this behind a flag, I will revert or rework it.

Live verification

Built this branch on an x86_64 Linux host and ran it against the same Ollama-backed OpenClaw sandbox as the installed pre-fix CLI. --timeout 5 forces the deadline on every trial, so the timeout path is exercised rather than waited for.

Host transport flags, read from the running openshell sandbox exec process:

PR   agent --timeout 5           --name <sb> -g <gw> --no-tty --timeout 35     exit 1
PR   agent --json --timeout 5    --name <sb> -g <gw> --no-tty --timeout 35     exit 1
PR   agent (no --timeout)        --name <sb> -g <gw> --no-tty                  exit 0
CTL  agent --timeout 5           --name <sb> -g <gw> --no-tty                  exit 0

Exit status, paired against the pre-fix CLI on the same sandbox:

transport	this branch	pre-fix CLI
non-JSON, timed-out turn	`1`	`0`
JSON, timed-out turn	`1` (2 of 2)	`0`
healthy turn	`0`, no guidance emitted	`0`

The pre-fix JSON run is the clearest evidence: its payload already carried "timeoutPhase": "provider" and the command still exited 0.

Emitted guidance, captured verbatim:

  The agent turn in sandbox '<sb>' timed out in the provider phase before producing a result.
  Reporting this as a failure: the deadline fired and no result reached this command.
  The output above is a partial trace. Tool calls in it may have already applied side effects.
  Documented recovery paths:
    nemoclaw '<sb>' sessions list          — locate the session key
    nemoclaw '<sb>' sessions export <key>  — export the partial transcript
    nemoclaw '<sb>' shields down           — unlock configuration writes
    nemoclaw '<sb>' config set --key <deadline-key> --value <seconds> --restart  — raise the deadline
  Two keys carry a deadline. agents.defaults.timeoutSeconds bounds the run, and
  `agent --timeout <seconds>` overrides it for a single run. models.providers.<id>.timeoutSeconds
  bounds the provider request, and no flag overrides it.
  Inspect the partial output and affected resources before retrying.

Why the guidance describes `--timeout` instead of offering it

Every timeout measured for #8723 reported phase provider. The gateway log shows two independent deadlines: --timeout N sets the run deadline (embedded run timeout ... timeoutMs=N000), while the provider request keeps models.providers.<provider-id>.timeoutSeconds ([model-fetch] start ... timeoutMs=60000 was unchanged by --timeout 150). A longer --timeout therefore does not recover the reported failure, so the failure text names the configuration keys and the documented commands that write them.

Evidence: Reviewed the complete 12-file diff through 68a7d47, including both documentation pages, user-visible diagnostics, comments, test titles, terminology, voice, and command presentation. The documentation matches the implementation: agent-run and provider-request deadlines remain distinct; a valid positive agent timeout adds a 30-second host buffer; a timed-out turn preserves partial output and returns failure; a completed reply that quotes the timeout sentence remains successful; and an unsafe phase label is omitted from diagnostic text without weakening timeout classification. Focused validation passed 116 tests across five loaded files, then 81 tests across the three suites that required the compiled shared boundary. The full normal commit hook passed.

Summary by CodeRabbit

New Features
- Added timeout-aware agent execution with clearer handling of run and provider-request deadlines.
- Preserved partial output and provided phase-specific recovery guidance when turns time out.
- Timed-out executions now return a non-zero exit status.
- Added guidance for inspecting sessions, updating timeout settings, and recovering sandbox configurations.
Documentation
- Expanded timeout configuration and command references, including CLI override behavior and deadline limitations.
Tests
- Added coverage for timeout parsing, detection, reporting, exit statuses, and JSON responses.

`nemoclaw <name> agent` spawned `openshell sandbox exec` without a timeout and forwarded none, so the transport ran on its own default of no timeout. A `--timeout` in the argv reached only the in-sandbox `openclaw agent`. When the in-sandbox turn stopped answering, the host command waited with nothing to end it. Read the requested `--timeout` from the argv the caller already passed and bound the transport at that value plus a fixed buffer, on both the JSON and non-JSON dispatch paths. The buffer keeps the in-sandbox turn first to answer, so a caller still receives the turn's own timeout report rather than a bare transport failure. The `exec` command already forwards `timeoutSeconds` this way; the agent wrapper now does the same. An argv with no `--timeout`, with `--timeout 0`, with a malformed value, or with the flag past a `--` terminator leaves the transport unbounded exactly as before, so no existing invocation changes its wait. This covers a caller who states a deadline on the command. A caller who sets only the onboarded `NEMOCLAW_AGENT_TIMEOUT`, as issue #8723 reports, passes no `--timeout` and still waits unbounded here; the exit-code and cancellation changes in this branch cover that path. The buffer is a choice rather than a derivation. Its doc comment records the measurements behind it and the range a reviewer can move it within. Signed-off-by: Hung Le <hple@nvidia.com>

`nemoclaw <name> agent` reported success when the turn's deadline fired without producing a result. Both transports exited 0, so a CI job or an evaluation harness recorded a timed-out turn as a pass. Neither existing guard covers this. The empty-dispatch guard requires both streams to be byte-empty, and OpenClaw prints its timeout report. The incomplete-turn classifier tests `livenessState === "abandoned"`, and two identical timed-out runs reported `blocked` and `working` instead. Classify the timeout from the signal each transport has. The JSON transport reads `meta.timeoutPhase`, which OpenClaw declares on `EmbeddedAgentRunMeta` and omits from a turn that answered; presence is the marker, so a phase added upstream is still classified. The non-JSON transport has only text, so it matches the sentence OpenClaw prints, the way the embedded-fallback branch already matches its own banner. Both exit 1 after the partial trace reaches the caller, and an upstream non-zero code is preserved. The failure text names where each deadline lives instead of offering `--timeout` as the fix. `--timeout N` sets the embedded run deadline, while the provider request keeps the deadline from `models.providers.<id>.timeoutSeconds`, so a provider-phase timeout does not respond to the flag. This changes a public contract: a command that exited 0 on a timed-out turn now exits 1. Signed-off-by: Hung Le <hple@nvidia.com>

`nemoclaw <name> agent` gained a host-side deadline and a nonzero exit for a timed-out turn, and neither was described anywhere. The recovery question #8723 raised was also unanswered: a reader who hit a timeout had no documented way to give the next attempt more time. Describe the host bound in the command reference, including the three argv forms that leave the OpenShell wait unbounded, and record that a turn whose deadline fired now exits 1 rather than the upstream 0. Add `timeoutPhase` to the JSON completion markers that already produce that exit. Explain in the inference timeout page that the two configuration keys bound different deadlines. `agents.defaults.timeoutSeconds` bounds the run and `agent --timeout` overrides it for a single run; the provider request keeps `models.providers.<provider-id>.timeoutSeconds`, which no flag overrides. Every timeout measured for #8723 fired in the provider phase, so a reader who raises only the run deadline is not helped. Add the in-place procedure beside the existing rebuild instruction. Name those same commands in the failure text, so an operator reads the documented `shields down` and `config set --restart` pair instead of an instruction to edit a file.

📝 Walkthrough

Walkthrough

Agent passthrough now parses agent timeouts, applies a 30-second host buffer, detects timeout results, preserves partial output, returns exit code 1, and reports phase-specific guidance. OpenClaw JSON provenance records valid timeout phases. Documentation describes timeout scopes and CLI behavior.

Changes

Agent timeout handling

Layer / File(s)	Summary
Timeout provenance contract `src/lib/openclaw/agent-json-provenance.ts`, `src/lib/openclaw/agent-json-provenance.test.ts`	Incomplete-turn signals now include valid `timeoutPhase` metadata. Tests cover valid, invalid, successful-tool, abandoned-turn, and combined-marker cases.
Dispatch timeout parsing and classification `src/lib/actions/sandbox/agent/passthrough-dispatch.ts`, `src/lib/actions/sandbox/agent/passthrough-dispatch.test.ts`	The dispatch layer parses positive `--timeout` values, calculates a 30-second host buffer, detects timeout output on both streams, and defines exit code `1`.
Timeout failure diagnostics `src/lib/actions/sandbox/agent/passthrough-help.ts`, `src/lib/actions/sandbox/agent/passthrough-help.test.ts`	Timeout failures report phases, possible side effects, recovery commands, and separate agent/provider deadline guidance.
JSON and non-JSON passthrough integration `src/lib/actions/sandbox/agent/passthrough.ts`, `src/lib/actions/sandbox/agent/passthrough.test.ts`	Both passthrough modes apply command-derived host deadlines, preserve partial output, and return exit code `1` for timed-out turns.
Timeout documentation `docs/reference/commands.mdx`, `docs/inference/configure-inference-timeouts.mdx`	The documentation describes timeout scopes, host deadline derivation, timeout failure behavior, and configuration updates.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: ⚪ Minimal · up to 11135

The command now bounds host waiting when a timeout is requested and reports timed-out turns as failures while preserving healthy-turn success; no actionable merge-blocking risk remains after normal checks and review.

`PRA-1` Blocker — Stop parsing a host timeout after an unknown OpenClaw option

Location: src/lib/actions/sandbox/agent/passthrough-dispatch.ts:334
Category: correctness
Problem: The timeout parser scans past unrecognized options and can treat a later `--timeout` token as a host deadline even when the unknown option consumes that token as its value.
Impact: An OpenClaw option that takes a value can cause its value `--timeout 30` to add a 60-second host timeout. The host can then terminate a turn that OpenClaw did not configure with a deadline.
Fix: Return null when an unrecognized option appears before a recognized timeout, so the host timeout is omitted unless the parser can establish the flag boundary.
Verification: Read requestedAgentTimeoutSeconds with argv `openclaw agent --unknown --timeout 30`; before the fix it returns 30, while the conservative parser must return null.
Test coverage: Add a requestedAgentTimeoutSeconds test where an unrecognized option consumes `--timeout` and `30`, and assert that agentDispatchDeadlineSeconds returns undefined.
Evidence: src/lib/actions/sandbox/agent/passthrough-dispatch.ts:334-342 scans each argument and returns a deadline for a later `--timeout` without rejecting unknown options. src/lib/actions/sandbox/agent/passthrough.ts:463-476 keeps JSON detection on the normal path when an unrecognized OpenClaw option occurs, because OpenClaw remains the argv source of truth. The changed dispatch comment states that unreadable argv must leave the host wait unbounded rather than shorten a turn without evidence.

Workflow run details

This automated review informs maintainers. Warnings and suggestions do not require a response. A maintainer decides whether to merge.

`agentDispatchDeadlineSeconds` added the buffer to a requested deadline without checking the sum stayed a safe integer. A `--timeout` at `Number.MAX_SAFE_INTEGER` produced a value the runtime rounds, so the command line carried a deadline that differed from the one it reported. Return undefined instead, which is how the module already treats every value it cannot read, and cover both sides of the boundary. Also record the fourth argv form that leaves the host wait unbounded. A `--timeout` after the `--` terminator is payload, not a deadline request, so a reader scanning a command line that contains `--timeout` needs to see that case listed beside the other three.

Input validation: timeout values require positive safe integers, the buffered value must remain safe, and diagnostic phase labels use a bounded token grammar. Authentication and authorization: unchanged. Dependencies and supply chain: unchanged. Error handling and information exposure: timed-out turns fail after preserving partial output; completed quoted replies remain successful; unsafe phase text is omitted. Cryptography: unchanged. Network exposure: unchanged. Tests: both transports, bounds, provenance, false-positive handling, and diagnostic safety are covered. System behavior: upstream nonzero and signal-derived statuses remain unchanged. Product scope is accepted #8723; no blocker found.

Security review follow-up: PASS at 11135ab. The CodeRabbit finding was valid and is fixed with the shared terminal-control sanitizer. Both timeout verdict forms and their recovery commands now render an inert, bounded sandbox name; valid names remain unchanged. Focused coverage exercises phase and no-phase diagnostics with newline and ANSI input. The other security categories and accepted product scope remain unchanged.

## Summary NemoClaw now infers the host-side OpenShell deadline only when it can parse the complete forwarded OpenClaw option sequence without ambiguity. Unknown options and positional tokens leave the host wait unbounded instead of treating a later `--timeout` token as an OpenClaw deadline. ## Related Issue Follow-up to #9056. Addresses the delayed [PR Review Advisor finding](#9056 (comment)). ## Changes - Recognize the documented separated, equals-form, boolean, and JSON option forms before `--timeout`. - Leave the host wait unbounded for unknown flags, positional tokens, consumed values, malformed timeout values, and tokens after `--`. - Document the unknown-option condition in the command reference. - Add regression coverage for the ambiguous `--unknown --timeout 30` sequence. ## Type of Change - [ ] Code change (feature, bug fix, or refactor) - [x] Code change with doc updates - [ ] Doc only (prose changes, no code sample modifications) - [ ] Doc only (includes code sample changes) ## Quality Gates - [x] Tests added or updated for changed behavior - [ ] Existing tests cover changed behavior — justification: - [ ] Tests not applicable — justification: - [x] Docs updated for user-facing behavior changes - [ ] Docs not applicable — justification: - [x] Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging) - [x] Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: an exact nine-category security review passed at `4aaaf7c3` with no actionable findings. Unknown or ambiguous argv does not authorize an inferred deadline, and forwarded arguments remain an argv array without shell interpretation. - [ ] Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue: ## Documentation Writer Review - [x] Documentation writer subagent reviewed the completed changes - Result: `docs-updated` - Evidence: `docs/reference/commands.mdx` now lists an unrecognized option before `--timeout` among the conditions that leave the OpenShell wait unbounded. The implementation and regression test enforce the same condition. - Agent: Codex Desktop   ## DGX Station Hardware Evidence - [ ] Tested on DGX Station - Tested commit: - Station profile/scenario: - Result: - Supporting evidence: ## Verification - [x] PR description includes a `Signed-off-by:` line and every commit appears as `Verified` in GitHub - [x] Normal `pre-commit`, `commit-msg`, and `pre-push` hooks passed, or `npm run validate:pr` passed after refreshing `origin/main` when hooks were skipped or unavailable - [x] Targeted behavior tests pass for the current change set, or tests are marked not applicable above — four focused agent-dispatch suites, 129 tests passed - [x] Applicable broad gate passed — `npm run validate:pr` passed, including repository checks, secret scanning, commit checks, and CLI type checking - [x] Quality Gates section completed with required justifications or waivers - [x] No secrets, API keys, or credentials committed - [ ] `npm run docs` builds without warnings (doc changes only) — build passed with 0 errors; Fern reported two existing repository warnings - [x] Doc pages follow the [style guide](https://github.com/NVIDIA/NemoClaw/blob/main/docs/CONTRIBUTING.md) (doc changes only) - [ ] New doc pages include SPDX header and frontmatter (new pages only) --- Signed-off-by: Apurv Kumaria <akumaria@nvidia.com>  ## Summary by CodeRabbit * **Bug Fixes** * Improved timeout option parsing for the `agent` command, including boolean and equals-form options. * Prevented unrecognized options from incorrectly creating a dispatch deadline. * Clarified that an unrecognized option before `--timeout` leaves the wait unbounded. * **Tests** * Added coverage for supported option formats and unknown-option handling.  --------- Signed-off-by: Apurv Kumaria <akumaria@nvidia.com>
