Summary of Changes

Hello @vtigo, 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 focuses on a stylistic refactor to enhance code consistency and maintainability. It streamlines how null checks are performed on properties within the RequestContext class, transitioning from multi-line conditional returns to single-line ternary expressions. This change contributes to a cleaner and more uniform codebase.

Highlights

• Code Style Standardization: Standardized property null check patterns within the RequestContext class by converting if/return statements to more concise ternary operators for improved consistency and readability.
• Refactoring RequestContext Properties: Specifically refactored the configuration and metadata properties in src/a2a/server/agent_execution/context.py to align with the new ternary operator style for handling _params null checks.

Code Review

This pull request aims to standardize null-checking patterns for properties by using ternary operators. The changes are in RequestContext.

The update to the configuration property is a good improvement in conciseness.
For the metadata property, the new implementation is logically correct, but I've suggested a small refactoring to improve readability and maintainability of the ternary expression.

Overall, a good step towards code consistency.
