Summary

Why

#78055 shows a fresh second final answer replaying an already-completed task after a newer user request and unrelated tool calls. That points at stale previous_response_id lineage being reused across completed final-answer boundaries. This surgical guard forces a full-context send for the first request after a phased final answer, then allows incremental behavior to resume inside the new turn.

Codex review: needs real behavior proof before merge.

Summary
The PR changes OpenAI WebSocket request planning so a new user turn after a phased final answer sends full context instead of reusing previous_response_id, and adds a planner regression test.

Reproducibility: no. high-confidence live reproduction was established here. Source inspection does show the planner-level path on current main: a strict extension after a phased final answer can still reuse previous_response_id for a new user message.

Real behavior proof
Needs real behavior proof before merge: The PR body and comments contain tests/CI status but no after-fix real runtime artifact showing the stale-final replay is fixed. After adding proof, update the PR body; ClawSweeper should re-review automatically. If it does not, ask a maintainer to comment @clawsweeper re-review.

Next step before merge
Contributor action is needed for real behavior proof, and the PR also needs a changelog entry or maintainer exemption before normal review can proceed.

Security
Cleared: The diff only changes OpenAI WebSocket request planning and a unit test; it does not add dependencies, workflows, permissions, secrets handling, or new code-execution surfaces.

Review findings

  • [P2] Add the required changelog entry — src/agents/openai-ws-request.ts:121
Review details

Best possible solution:

Land a narrow version after the contributor adds redacted real behavior proof, a changelog entry, and targeted validation; keep the broader stale subagent/history work tracked separately.

Do we have a high-confidence way to reproduce the issue?

No high-confidence live reproduction was established here. Source inspection does show the planner-level path on current main: a strict extension after a phased final answer can still reuse previous_response_id for a new user message.

Is this the best way to solve the issue?

Yes for the narrow WebSocket lineage slice: forcing one full-context send across a final-answer-to-new-user boundary is targeted and preserves incremental sends for ordinary continuations. It is not merge-ready until proof and changelog are supplied.

Full review comments:

  • [P2] Add the required changelog entry — src/agents/openai-ws-request.ts:121
    This changes user-visible agent behavior by preventing stale OpenAI WebSocket lineage reuse after final answers, but the PR only changes source and tests. OpenClaw policy requires user-facing fixes to include an Unreleased CHANGELOG.md entry, otherwise the fix can ship without release notes.
    Confidence: 0.88

Overall correctness: patch is incorrect
Overall confidence: 0.82

What I checked:

  • Current-main planner behavior: Current main plans an incremental WebSocket payload whenever the full input strictly extends the prior request plus response chain, with no final-answer-to-new-user boundary check before attaching previous_response_id. (src/agents/openai-ws-request.ts:93, 0da9f7e88d6f)
  • PR behavior change: The PR adds final-answer and new-user-turn detection, then falls back to full context when both are true instead of returning the incremental payload. (src/agents/openai-ws-request.ts:121, db85f7f9c450)
  • Regression coverage: The PR adds a planner test asserting that a previous assistant final_answer followed by a new user message produces mode: full_context and omits previous_response_id. (src/agents/openai-ws-stream.test.ts:1835, db85f7f9c450)
  • CI status: The latest head has successful check runs including check-test-types, check-lint, check-prod-types, and the security fast checks. (db85f7f9c450)
  • Real behavior proof missing: The PR body and follow-up comments list git diff --check, blocked local test attempts, and CI status, but no after-fix OpenClaw runtime output, redacted logs, screenshot, recording, or artifact showing the stale-final replay no longer occurs. (db85f7f9c450)
  • Changelog entry missing: The PR patch modifies only src/agents/openai-ws-request.ts and src/agents/openai-ws-stream.test.ts; no CHANGELOG.md entry is added for this user-visible agent behavior fix. (CHANGELOG.md:5, db85f7f9c450)

Likely related people:

  • steipete: Peter Steinberger introduced the OpenAI Responses WebSocket-first stream path and appears throughout recent history for openai-ws-stream.ts, openai-ws-request.ts, and continuation/replay fixes. (role: introduced behavior and recent maintainer; confidence: high; commits: 7ced38b5ef2a, cabdf5bbc4c6, cf511288b84b; files: src/agents/openai-ws-stream.ts, src/agents/openai-ws-request.ts, src/agents/openai-ws-stream.test.ts)
  • vincentkoc: Vincent Koc has nearby merged work on provider request policy, native WebSocket endpoint checks, and prompt-cache boundary handling used by the affected WebSocket request path. (role: adjacent owner; confidence: medium; commits: 64f28906de09, e250ea3668f6, 5ddca5dd56e9; files: src/agents/openai-ws-request.ts, src/agents/openai-ws-stream.ts, src/agents/openai-ws-connection.ts)

Remaining risk / open question:

  • No after-fix real OpenClaw runtime artifact shows the stale final-answer replay is fixed in a real setup.
  • The user-facing fix lacks the required CHANGELOG.md entry.
  • The broader stale subagent/history cluster remains open, so this PR should stay scoped to the OpenAI WebSocket lineage slice.

Merge-tree is clean against current main and the review threads are clean. Three required checks are still red and blocking:

  1. Real behavior proof — the planner regression alone won't satisfy the gate. Needs a captured runtime artifact showing the new full-context-after-final-answer guard firing on a [Bug]: Subagent announce can deliver stale output and subagent sessions may inherit unrelated history #78055-style stream (the trace from the instrumentation in fix: trace OpenAI WebSocket response lineage #78146 would be a natural source for this — happy to coordinate if useful).
  2. check-test-types — runs pnpm tsgo:test (package.json:1336 → pnpm tsgo:core:test && pnpm tsgo:extensions:test). The PR body says local typecheck couldn't run; once node_modules is back, pnpm tsgo:test:src should reproduce the failing shard fastest.
  3. CHANGELOG entry, or maintainer exemption noted on the PR.

Otherwise this is the cleanest of the three #78055-cluster PRs (#78142 / #78146 / #78147) — surgical guard, narrow blast radius, planner regression in place.

Thanks @100yenadmin. Closing this as superseded by #79726.

This PR works around a suspected stale replay by changing OpenClaw's custom OpenAI Responses WebSocket lineage planner. We are removing that planner instead. #79726 deletes the custom src/agents/openai-ws-* transport and hands explicit openai-codex/* Responses streaming back to PI's native WebSocket-capable transport.

That is the cleaner boundary: OpenAI/Codex Responses chaining stays inside the PI/Codex transport that owns it, and OpenClaw no longer needs to decide when to disable previous_response_id after a final answer. OpenClaw still wraps the stream for the pieces it owns: auth injection, abort signals, session id propagation, and prompt-cache boundary stripping.

Proof in #79726:

  • removes the deleted planner target (openai-ws-message-conversion.ts) and its tests instead of landing another heuristic in it
  • removes shouldUseOpenAIWebSocketTransport, custom WS session cleanup, and openaiWsWarmup from runtime/docs/tests
  • verifies no remaining custom WS symbols/config/docs with rg
  • targeted PI/OpenAI tests passed, and Testbox pnpm check:changed passed

#78055 is still referenced, but the remaining issue scope includes subagent announce/session-history contamination beyond this custom-WS lineage theory.
