When should your coding agent compact?编程助手该在什么时候压缩上下文？

A coding agent keeps your whole conversation in its head. When that gets too big, it writes a summary and carries on from the summary. Compact too early and you keep paying to rebuild the same context. Compact too late and every request drags a heavy load. These charts show where the sweet spot sits, using real sessions.编程助手会把整段对话都放在脑子里。对话太长时，它会写一份摘要，再从摘要接着干。压缩太早，就要一遍遍花钱重建同样的上下文；压缩太晚，每次请求都背着沉重的负担。这些图用真实的使用记录告诉你，平衡点大约在哪里。
