AI Summary

Fixes a critical bug where sending identical user prompts in a conversation caused a 400 error with Claude 4.6+ due to overly aggressive deduplication logic.

Key Highlights

  • Fixes Claude 4.6+ 400 error (assistant-prefill final message not supported) on repeated prompts.
  • Updates deduplication logic to only skip appending if the tail message is already identical.
  • Allows normal continuation of chat sessions with repeated user prompts.

Full Release Notes

修复同一对话中重复发送相同用户提示词时，因历史去重逻辑误判而不再追加本轮 user 消息、导致请求以 assistant 结尾并触发 Claude 4.6+ 返回 400（assistant-prefill final message is not supported）的问题；现仅在尾部已是相同 user 内容时才跳过追加，重复提示词可正常续聊。

---

Fix repeated identical user prompts in the same conversation failing with Claude 4.6+ 400 (assistant-prefill final message is not supported) because dedup logic skipped appending the new user turn when matching text appeared earlier; append is now skipped only when the tail message is already that user content, so identical prompts can continue normally.
