 ## Q: Will these rules consume a lot of the AI agent's **context window**?
 
-**A:** No. The always-on rules are designed to be lightweight and efficient, and should not consume a lot of the AI agent's context window. The "glob" rules are designed to be applied only to the related file types specified in the rule.
