What problem does it solve?

Efficiently add Malli schemas to API endpoints in the Metabase codebase with proper patterns, validation timing, and error handling.

Core Features & Use Cases

• Query params have schemas with :optional true and :default where appropriate
• Request body has a schema (for POST/PUT)
• Response schema is defined (using :- after route string)
• Use existing schema types from ms namespace when possible
• Consider creating named schemas for reusable or complex types
• Add contextual error messages for validation failures

Add a Malli schema to an endpoint, then attach to the endpoint macro; test by invoking the endpoint to verify validation.
