因为不少公益站不支持远程压缩，只能依赖本地压缩。然而，Codex 自带的默认压缩 Prompt 是这样的： 
You are performing a CONTEXT CHECKPOINT COMPACTION. Create a handoff summary for another LLM that will resume the task.

Include:
- Current progress and key decisions made
- Important context, constraints, or user preferences
- What remains to be done (clear next steps)
- Any critical data, examples, or references needed to continue

Be concis...
