Outcome

nemoclaw <sandbox> agent … --json now exits 0 for completed OpenClaw tool turns whose reply starts with a reply directive or includes MEDIA: lines. Paused, blocked, pending-continuation, and timed-out turns, and turns that end with OpenClaw's no-final-answer fallback reply, still exit 1 when replayInvalid is set.

Reason

#12502 added a corroborated classifier for replayInvalid turns: it accepts a completed tool turn when the final visible text matches a reply payload. Two gaps remain:

  • OpenClaw strips leading reply directives such as [[reply_to_current]] and MEDIA: lines from payloads, so those completed turns still exit 1.
  • The classifier does not check livenessState, continuationPending, timeoutPhase, or the fallback reply, so a paused or blocked turn, or one that ended with "The tool run finished, but no final summary was produced…", can exit 0.

Fixes #11844

Changes

  • Keep fix(inference): fit managed Qwen serving to 64 GB Spark #12502's classifier and extend hasCompletedToolReply: ignore the leading reply directives OpenClaw strips, match MEDIA: lines against the payload's media URLs, and reject a declared liveness state other than working, a pending continuation, a timeout phase, and the fallback reply. A missing livenessState stays accepted, as fix(inference): fit managed Qwen serving to 64 GB Spark #12502's tests expect.
  • Update the agent reference in docs/reference/commands.mdx.
  • Add unit cases for both envelope shapes and a passthrough case for exit 0. E2E reply parsing shares this classifier.

Verification

Review notes

  • The fallback reply is matched by its exact text, since OpenClaw exposes no separate metadata for it. The text is identical from OpenClaw 2026.8.2 through 2026.9.6.
  • Any declared liveness state other than working keeps replayInvalid incomplete; a turn with no livenessState follows fix(inference): fit managed Qwen serving to 64 GB Spark #12502.

Summary by CodeRabbit

  • Bug Fixes
    • Completed OpenClaw tool turns are now recognized when their replies match the visible assistant response, including replies with leading directives or media links.
    • Turns with pending continuations, aborted work, failed tool calls, or fallback replies remain classified as incomplete. This helps prevent completed turns from being incorrectly flagged while preserving incomplete-turn diagnostics.
  • Documentation
    • Clarified how completion checks handle reply matching, media links, and incomplete turns.

OpenClaw sets replayInvalid when a turn cannot be retried safely, which
includes every completed turn in which a mutating tool such as exec ran.
The agent JSON passthrough treated that marker as an incomplete turn, so
a successful tool turn printed its answer and then exited 1 with partial
trace guidance (NVIDIA#11844).

Treat replayInvalid as the only incomplete marker as complete only when
the final response proves delivery: livenessState working, stopReason
stop, not aborted, no run error, at least one tool call with no
failures, and a delivered reply payload with text or media that is not
an error or reasoning payload. Gateway envelopes must also report status
ok and summary completed. Payload presence replaces a visible-text match
because OpenClaw strips reply directives and MEDIA lines from payloads.
Abandoned, timed-out, incomplete_turn, paused, blocked, aborted,
failed-tool and undelivered turns still exit 1 with the side-effect
warning. The non-JSON transport does not read this metadata and already
exits 0. Update the agent command reference to match.

Validation: unit cases model real OpenClaw 2026.9.1 gateway and local
output; the completed-turn cases fail before the change and pass after
it, and removing any single completion condition fails a test. Related
CLI suites (377 tests), e2e-support (51 tests), the growth guardrails,
typecheck:cli, oxfmt and oxlint pass after dev-setup. On a real macOS
Colima sandbox with NVIDIA-hosted Nemotron, a forced exec prompt
returned the same answer through both builds; main exited 1 and this
change exited 0. A plain-text turn exits 0 on both.

📝 Walkthrough

Walkthrough

The change updates OpenClaw JSON-turn completion checks. The checks validate turn state and compare normalized visible replies with response payloads. Tests cover gateway, local, and passthrough cases. Command documentation describes the completion criteria.

Completion checks reject pending continuation, declared liveness states other than "working", and the settled-tool fallback reply. Reply matching strips leading directives and checks non-media text and media URLs against the payload. Tests cover accepted completed turns and incomplete cases, including replayInvalid: true. Documentation describes these criteria.

Explanation

Issue [#11844] requires a deterministic regression test with an ordered assistant tool call, matching tool result, and final assistant response. The new completed-turn fixtures use toolSummary metadata and final payload text, but do not include the assistant tool call or matching tool result. The implementation covers reply directives, MEDIA: URLs, liveness, continuation, timeout, fallback, JSON passthrough, nonzero incomplete turns, stderr classification, plain-text behavior, and redaction. Transcript order remains unvalidated in the reviewed JSON path.

Resolution

Add a deterministic completed-turn fixture that includes the complete ordered assistant tool call, matching tool result, and final assistant response. Validate that structure before suppressing replayInvalid. Add a negative fixture that has completion metadata and a final payload but lacks the matching transcript, and verify exit 1 with the side-effect warning.

OpenClaw writes a fixed fallback reply when a tool turn settles without a
final answer. Treat that reply, a pending continuation, and an empty media
URL as incomplete so those turns keep the side-effect warning.

@coderabbitai The json output has no transcript to validate. toolSummary and stopReason are OpenClaw's summary of the turn and replayInvalid means a retry would repeat side effects, not that the transcript is broken. Fetching the transcript would add a second sandbox call to every turn that could fail and bring back false exit 1s, so I’d like to keep the check on the envelope. I verified the live transcript for this turn is complete and in order.

@bowenzhu21, you’re right. The JSON output has no transcript for this wrapper to validate. I should not have asked the wrapper to fetch one with a second sandbox call.

The completed-turn check uses OpenClaw’s final envelope, including toolSummary and stopReason. Your live transcript check supports the behavior in #11844, but the wrapper itself does not verify transcript order. I withdraw the Linked Issues check’s requirement to add transcript validation to this JSON path. Thanks for clarifying.

Learning: For NVIDIA/NemoClaw's OpenClaw agent JSON passthrough, the JSON output does not include the assistant/tool transcript. `toolSummary` and `stopReason` are OpenClaw's summaries of the turn. `replayInvalid` indicates that retrying could repeat side effects; it does not by itself mean the transcript is broken. Fetching the transcript would require a second sandbox call that could fail and cause false exit-1 results.

NVIDIA#12502 added a corroborated replay-risk classifier on main. Keep it as
the base and narrow this change to the cases it still gets wrong:

- Accept a completed tool turn whose visible text starts with reply
  directives, or carries MEDIA: lines that the payload holds as media.
- Keep replayInvalid incomplete for a declared liveness state other than
  working, a pending continuation, a timed-out turn, or OpenClaw's
  no-final-answer fallback reply.

A missing liveness state stays accepted, as main's tests expect.

Validation: these tests fail in 20 cases against main's classifier and
pass with this change, along with main's own tests. vitest for
src/lib/openclaw and src/lib/actions/sandbox/agent (402), the E2E-support
output tests (51), growth guardrails, typecheck:cli, oxfmt, oxlint, and
the commit hooks pass.

Updated after #12502 merged. It added a corroborated classifier for replayInvalid turns that overlaps this PR, so I merged main, kept #12502's classifier as the base, and narrowed this PR to the cases it still misses:

  • Completed tool turns whose reply starts with a reply directive or includes MEDIA: lines still exit 1 on main.
  • Paused, blocked, pending-continuation, and timed-out turns, and turns that end with OpenClaw's no-final-answer fallback reply, can exit 0 on main.

A turn with no livenessState stays accepted, as #12502's tests expect. This PR's tests fail in 20 cases against #12502's classifier and pass with this change, along with #12502's own tests. The description is updated to match.

Strip only the leading directives OpenClaw removes from payload text
(reply_to_current, reply_to:<id>, audio_as_voice), so bracketed answer
text such as [[56]] still matches its payload. Trim lines only to find
MEDIA: lines, so an indented reply still matches the payload text, which
OpenClaw keeps verbatim.

Validation: OpenClaw 2026.9.1's parseReplyDirectives produces the payload
text and media these tests assume; its directive and reply parsers match
2026.9.2. The new cases fail before this change and pass after it. vitest
for src/lib/openclaw and src/lib/actions/sandbox/agent (410), the
E2E-support output tests (51), growth guardrails, typecheck:cli, oxfmt,
