Summary of Changes
Hello @holtskinner, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request refactors the A2ABaseModel by removing custom attribute handling that previously supported deprecated camelCase field access. The change enforces the use of snake_case for direct attribute access and modification on model instances, streamlining the API and removing legacy functionality.
Highlights
- Deprecation Removal: Removed the custom
__getattr__and__setattr__methods fromsrc/a2a/_base.pythat previously allowed deprecatedcamelCaseattribute access and setting onA2ABaseModelinstances. This eliminates the need forwarnings,Any, andClassVarimports related to this functionality. - Enforced Snake Case: Direct attribute access and modification on
A2ABaseModelinstances now strictly requiresnake_casefield names. Attempting to usecamelCasealiases for attribute access or setting will now raise anAttributeError, providing clearer guidance to developers. - Test Updates: The test suite in
tests/test_types.pyhas been updated to reflect and verify this new behavior. Thetest_camelCasefunction was renamed totest_camelCase_access_raises_attribute_errorand now asserts thatAttributeErroris correctly raised whencamelCasealiases are used for attribute access or setting, while confirming thatsnake_caseusage remains functional.

Code Review
This pull request removes the deprecated camelCase attribute access from A2ABaseModel. The test changes in tests/test_types.py require re-introduction of __getattr__ and __setattr__ in A2ABaseModel to provide the developer-friendly error messages that the tests expect.
