上下文压缩防重复执行：保留“用户请求→已执行动作”成对信息

• Conversation has context compaction enabled or regularly triggered.
• You can inspect before/after summaries and turn-level outputs for regression checks.

1. Create a reproducible request→action pair (e.g., user asks change; agent confirms completed).
2. Force or wait for compaction, then inspect summary to confirm both request and action status are preserved as a pair.
3. If action confirmation is missing, add summarization rule to explicitly encode completion status in compact memory.
4. Run follow-up prompt referencing the prior task; verify agent does not re-announce or re-execute completed work.

• Proposed fix direction is from issue discussion; final implementation may differ（需验证）.
• Overly verbose compaction summaries can increase token cost; keep structured but concise pairs.
