AI Summary

Fixes a critical bug in conversation history deduplication that caused API errors with Claude 4.6+.

Key Highlights

  • Fixed logic that skipped appending user prompts if they matched history, causing 'assistant-prefill final message is not supported' errors.
  • Updated deduplication logic to skip appending only when the tail message is already the user content.
  • Allows identical prompts to continue normally without triggering errors.

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.
