Summary of Changes
Hello @pankaj-bind, 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 significantly improves the reliability of the new_task function by introducing explicit validation for the context_id parameter. It addresses a potential source of errors by enforcing that context_id values conform to the UUID format, thereby enhancing data integrity and system stability. Comprehensive tests have been added to verify the new validation logic.
Highlights
- Input Validation: Implemented robust validation for the
context_idparameter within thenew_taskfunction insrc/a2a/utils/task.py. This ensures that any providedcontext_idis a valid UUID, preventing malformed identifiers from causing downstream issues. - Error Handling: Modified the
new_taskfunction to raise aValueErrorif an invalidcontext_idis supplied. The function's docstring has been updated to reflect this new exception condition. - Test Coverage: Expanded the test suite in
tests/utils/test_task.pywith new unit tests specifically for thenew_taskfunction. These tests cover scenarios involving valid, invalid (e.g., 'not-a-uuid'), and empty stringcontext_idinputs, ensuring the new validation logic behaves as expected.

Code Review
This pull request successfully adds input validation for context_id in the new_task function, raising a ValueError for invalid UUIDs. The accompanying tests cover the new logic for valid, invalid, and empty string context_ids. My review includes suggestions to refine the exception handling in the implementation for more precision and to consolidate the new tests using parameterization for better maintainability.

Description
This update addresses an issue where the
new_taskfunction insrc/a2a/utils/task.pydid not validate the format of thecontext_idwhen it was provided. Invalid or malformedcontext_idvalues, such as empty strings or non-UUID strings, were not being properly handled, which could lead to downstream errors.The changes in this PR introduce a validation check to ensure that any provided
context_idis a valid UUID. If thecontext_idis invalid, aValueErroris raised. If nocontext_idis provided, a new UUID is generated as before.
