解决什么问题What problem it solves

决定「哪些内容放进模型的有限窗口」这件事本身。Deciding what goes into the model's limited window is itself a discipline.

这是什么What it is

Anthropic 把上下文称为「关键但有限的资源」。

核心工作是持续筛选：什么进窗口、什么留在外面。

Anthropic calls context "a critical but finite resource" for agents.

The core work is curating what enters the window and what stays out.

为什么需要知道Why it matters

窗口不是越大越好。会筛内容，才知道该塞什么、该删什么。Bigger windows are not free. Curating is how you decide what to include and what to drop.

接着读什么，为什么What to read next, and why

上下文窗口Context Window
窗口是容量；工程关心放什么、何时更新。Capacity differs from deciding what to include and update.
