# BB.Dsl.ParameterTransformer (bb v0.17.0)

Copy Markdown View Source

Generates parameter schema and default values from DSL definitions.

This transformer processes the `parameters` section, generating:

- `__bb_parameter_schema__/0` - Returns the Spark.Options schema for validation
- `__bb_default_parameters__/0` - Returns default values as `{path, value}` tuples

At runtime, these are used by `BB.Robot.Runtime` to register parameters with proper validation schemas.
