Context Compression

Goal

Create a short, loss-minimized working summary that lets the next turn or next agent continue immediately.

Default behavior

• This skill is proactive, not opt-in.
• When any trigger below applies, compress state for yourself before continuing.
• Do not wait for the user to explicitly say "压缩上下文".
• Only show the compressed summary to the user when it helps alignment, handoff, recovery, or the user asked for a recap.
• Prefer silent/internal compression over repeating long restatements in normal replies.
