Summary of Changes

Hello @Moshiii, 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 refines the user experience of the helloworld client by optimizing its logging behavior and enhancing the readability of its JSON output. The changes aim to make the client's console output cleaner and easier to parse, both for debugging and general observation.

Highlights

• Logging Configuration: Suppressed verbose logging output from the 'a2a.client.client' module by setting its log level to WARNING, reducing noise in the console.
• JSON Output Formatting: Updated the printing of Pydantic model responses to use model_dump_json with indent=2, ensuring pretty-printed and more readable JSON output.

Code Review

This pull request improves the output of the helloworld test client by pretty-printing the JSON responses and suppressing verbose logs from the a2a.client.client library. The changes are good and improve readability. I've added a couple of minor suggestions to use the configured logger instead of print() for consistency with the rest of the script.

[gemini-code-assist]

For consistency with how other data structures are logged in this file (e.g., the agent card on lines 52-54), it would be better to use the configured logger instead of print(). This provides more flexible output control through logging configuration.

Suggested change

	print(response.model_dump_json(indent=2, exclude_none=True))
	logger.info(response.model_dump_json(indent=2, exclude_none=True))

[gemini-code-assist]

For consistency, it's better to use the configured logger here instead of print(), similar to the other logging calls in this file.

Suggested change

	print(chunk.model_dump_json(indent=2, exclude_none=True))
	logger.info(chunk.model_dump_json(indent=2, exclude_none=True))
