Version: 2026.4.23 Platform: macOS (Darwin 25.4.0) Surface: Web chat (control UI)

Describe the bug

When the assistant sends a reply, the message does not appear in the control UI until the user sends a subsequent message. At that point, both the assistant's previous reply and the new exchange become visible.

Steps to reproduce

  1. Send a message to the assistant in the web chat UI
  2. Wait for the assistant to reply
  3. Observe: the reply is not rendered
  4. Send a second message
  5. Observe: the first reply now appears along with the second exchange

Expected behavior

Assistant replies should render immediately upon receipt without requiring a follow-up message from the user.

Likely cause

The UI's real-time update listener (WebSocket/SSE) appears to receive the message but does not trigger a re-render. A re-render only occurs when the user's next send causes a state update.

extent analysis

TL;DR

The issue can be addressed by ensuring the control UI re-renders immediately after receiving the assistant's reply, potentially by updating the state or triggering a manual re-render.

Guidance

  • Verify that the WebSocket/SSE connection is correctly established and receiving messages from the assistant.
  • Check the UI's state update logic to ensure it triggers a re-render when a new message is received from the assistant, not just when the user sends a message.
  • Investigate if there's a specific condition or flag that needs to be set to force a re-render after receiving an assistant's reply.
  • Consider adding a manual re-render call after processing the assistant's reply to ensure the UI updates immediately.

Example

No specific code example can be provided without knowing the exact implementation details, but the fix might involve calling a forceUpdate() or similar method after receiving the assistant's reply.

Notes

The exact solution depends on the specific implementation of the UI and its state management. This guidance assumes a typical React-like environment but may need adjustments based on the actual framework or library used.

Recommendation

Apply a workaround by manually triggering a re-render after receiving the assistant's reply, as the root cause seems related to the UI's update mechanism rather than a version-specific issue.
