+
+Zookeeper has three modes: Auto, Standard, and Thoughtful. Modes change how much reasoning
+Zookeeper applies before it responds. Use Auto when you want Zookeeper to choose for you, Standard
+for quick work, and Thoughtful for complex CAD tasks that benefit from deeper reasoning.

+
+## Auto
+
+Auto chooses the model and reasoning effort for the task. Start here when you want Zookeeper to
+balance speed, cost, and capability automatically.
+
+## Thoughtful
+
+Thoughtful takes more time, but gives Zookeeper more reasoning depth. Use it for complex CAD
+modeling, multi-step edits, and workflows where quality matters more than response speed.
+
+## Standard
+
+Standard prioritizes faster responses with less reasoning depth. Use it for simple geometry
+changes, quick iterations, web search, documentation lookup, or general questions about a design.
+
+## Availability
+
+Your plan determines which modes you can select. Modes that are not included in your plan still
+appear in the selector with upgrade messaging, so you can see what is available on paid plans.
+
+Free users can select Auto only. Paid plans include all three modes: Auto, Standard, and Thoughtful.
+
+### Free plan
+
+On the Free plan, Auto is selectable. Standard and Thoughtful stay visible but disabled until your
+plan includes them.

+On paid plans, Auto, Standard, and Thoughtful are all selectable. Use Auto for automatic selection,
+Standard for speed, or Thoughtful for deeper CAD reasoning.
