Let's look into the example of building tools. They can be used by AI Agents, MCP, and others. The downside: you have to provide the input arguments in a specific form so that we can upcast the data before calling the tool. Most users won't ever do that, and it's error prone. Now: the config schema defines the structure, and the modeler turns that into a frontend widget. Strings become text inputs. Booleans become checkboxes. Lists get add/remove controls. Nested mappings become fieldsets. You can toggle between the structured editor and raw YAML at any time. Changes sync both ways. And in YAML mode, you get real-time schema validation. Type mismatches, missing required fields, unexpected properties -- all flagged immediately. This makes complex configuration accessible to people who would never write YAML by hand.
