### Summary Fixes duplicated Prompts/context in ACP threads after sending a message, as reported in #53201. ### Root Cause The thread already inserts the user prompt optimistically at send time. If an ACP server also echoes UserMessageChunk updates for the same prompt, the same content is appended again, which can duplicate rendered context sections. ### Fix Ignore echoed UserMessageChunk updates while a turn is actively running, so user prompt content is not appended twice. ### Validation - Reproduced with OpenCode ACP flow from the issue. - Confirmed duplication appears after send (not in the input box). - Confirmed duplicate Prompts/context no longer appears with the fix. ### Video [Screencast from 2026-04-06 08-21-32.webm](https://github.com/user-attachments/assets/33075312-9af7-4dd5-a2a3-5e1169b80243) ### Self-Review Checklist - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content is consistent with the [UI/UX checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) - [x] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable Closes #53201 ## Release Notes - Fixed duplicated Prompts/context in ACP conversations when servers echo user message chunks after send. |
