What happened?

When the assistant asks a question through the question dock, choosing an option can show a toast with:

请求失败
[object Object]

The observed session export shows the answer was actually accepted and the assistant continued with the chosen action. The user-visible failure is therefore misleading: the app reports a raw object instead of a readable response-state message.

Affected observed case:

• Question: 怎么处理这个 perf CI？
• Selected answer: 重跑 failed job
• Session export: docs/debug-session-log/pawwork-session-nimble-engine-2026-05-21-14-47-54-question-failed.json
• App version in export: 0.0.0-prod-202605201748

Which area seems affected?

App flow or product behavior; UI or design system; Model harness, prompts, tools, or session mechanics.

How much does this affect you?

Breaks an important workflow. The question dock is a decision point; showing [object Object] makes it look like the answer failed even when it may have succeeded.

Steps to reproduce

1. Open a session where the assistant calls the question tool.
2. Choose an option in the question dock and submit.
3. In the observed failure, a toast appears: 请求失败 [object Object].
4. The session export still shows the question tool completed with the selected answer and the assistant continued.

Potentially related reproduction path: submit the same question response again while the external-result entry has already been resolved, or while the dock remains visible before SSE/global sync removes it.

What did you expect to happen?

• If the answer is accepted, the dock should close or become non-interactive without showing a failure toast.
• If the answer was already accepted elsewhere or by an earlier click, the app should treat that as an idempotent completion, not a user-facing failure.
• If the response really is stale/invalid, the toast should use readable copy, never [object Object].

PawWork version

OS version

macOS 25.5.0 from the session export.

Can you reproduce it again?

Diagnostics

Evidence from the session export:

• The question tool part is completed and contains the selected answer:
  • state.output: User has answered your questions: "怎么处理这个 perf CI？"="重跑 failed job"...
• The assistant then executed the chosen action:
  • gh run rerun 26230861270 --failed
  • exit 0
