Breaking Changes

SchemaParseError for Invalid Schema Data

• Schema validation errors now raise SchemaParseError instead of Pydantic ValidationError - When parsing invalid schema data (e.g., "minimum": "not_a_number"), the library now raises SchemaParseError instead of passing through Pydantic's ValidationError. Users catching pydantic.ValidationError for schema validation failures should update to catch SchemaParseError. The original error is preserved in the original_error attribute. (#2786)

Bug Fixes

CLI Now Correctly Outputs to stdout

• Fixed CLI to actually output to stdout when --output is not specified - The --output argument has always documented (default: stdout) in --help, but previously no output was produced. Now works as documented. (#2787)

Other Notable Changes

• generate() function now returns str | GeneratedModules | None instead of None - Existing code ignoring the return value is unaffected. (#2787)
• Error message for multi-module output without directory changed to be more descriptive. (#2787)
