ability to set certain tools as always loaded

[shwethasuresh256]

The new claude cli triggers automatic lazy loading when the tools take up more than N% context window space.

Is there a way to set certain tools as always loaded (defer_loading=false) in the Agent SDK? If not can we please have this feature.

We're bumping up against this as well. If we had this, we would be able to enable some really neat experiences. Right now, we can tell people to use the CLI, and when they do they get a great Tools/MCP/Plugins experience. But when we try to help them move from "you manually use the CLI" to "your automated processes use the SDK" they lose a lot of the functionality they learned with the CLI.

This is probably the biggest gap keeping the SDK from being fully valuable to us
