Claude Code 的后台子智能体现在占用更少的用量额度。 运行中的子智能体每 30 秒更新一次状态行，而此前每次更新都会重新读取其完整对话。现在改由 Haiku 5.5 根据简短笔记来生成，因此每次更新的成本降低约 99%。

Background subagents in Claude Code now use less of your usage limit.
A running subagent updates its status line every 30 seconds, and each update used to re-read its whole conversation. Now Haiku 5.5 writes it from short notes instead, so each update costs about 99% less.
