Pull Request Overview

This PR updates the client code to support new “agent evaluation” and “with credentials” operations, refactors import paths, and standardizes return types and request headers.

• Refactored import locations for JSON encoder and (de)serializer utilities under _utils
• Added new builders and operations for agent evaluation, connection credentials, and red team polling
• Updated method signatures to include client_request_id, adjusted HTTP status checks to expect 201 for create calls, and switched paged return types to ItemPaged/AsyncItemPaged

• Consider adding unit tests for build_connections_list_with_credentials_request to verify that the request method, URL, and query parameters serialize correctly.

• The HTTP method for build_connections_get_with_credentials_request was changed from GET to POST, which will likely break the expected GET endpoint. It should remain GET unless the service contract was intentionally updated.

    return HttpRequest(method="POST", url=_url, params=_params, headers=_headers, **kwargs)

• case_insensitive_dict is used here but not imported in this module; add from azure.core.utils import case_insensitive_dict to avoid a NameError.

    _headers = case_insensitive_dict(kwargs.pop("headers", {}) or {})

sdk/evaluation/azure-ai-evaluation/azure/ai/evaluation/_common/onedp/models/_enums.py:46

• [nitpick] The enum member name ANSII_ATTACK is misspelled; the abbreviation should be ANSI, so update the name and value to ANSI_ATTACK.

    ANSII_ATTACK = "ansii_attack"
