Context Window Guide

Published March 2026
Look inside
Every file you open, every tool call result, and every message goes into the context window, and Claude can only see what is currently inside it. Once it fills, the oldest content gets compressed or dropped, and Claude starts forgetting your instructions and earlier decisions as quality degrades. The real fix is keeping the context clean.
