The quarkus-example module lacks test coverage for the AgentResource endpoints. The chat and health endpoints should have tests to verify correct behavior, error handling, and response formatting. Consider adding REST-assured tests for both successful and error scenarios.

+                    .entity(new ErrorResponse("Error processing request: " + e.getMessage()))


The error handling catches a generic Exception and includes the exception message in the response. This could potentially expose sensitive information such as API keys or internal system details if they appear in exception messages. Consider sanitizing the error message or using a generic error response for security.

Suggested change

.entity(new ErrorResponse("Error processing request: " + e.getMessage()))

.entity(new ErrorResponse("An internal error occurred. Please try again later."))

+                    "claude-sonnet-4.5",


The model name 'claude-sonnet-4.5' appears to be incorrect. Based on Anthropic's naming conventions, this should likely be 'claude-3-5-sonnet-20241022' (matching the default in AgentScopeConfig.java line 192) or another valid Claude model version. The current format doesn't match Anthropic's versioning scheme.

The model name 'gpt-4o-mini' is used in the test, but the default in AgentScopeConfig.java (line 127) is 'gpt-4'. For consistency and clarity, consider using the same default model name in tests as specified in the configuration, unless there's a specific reason to test with a different model.

The error messages for missing API keys use inconsistent formatting. Some messages end with 'Set agentscope.x.api-key' (lines 121-122, 145-146, 207-208) while others don't follow this pattern consistently. Consider using a uniform format for all error messages, such as: 'API key is required. Configure it using agentscope.{provider}.api-key'

+        };


The switch statement uses a default case that throws an exception, but it doesn't validate that the provider string is not null or empty before attempting the switch. If config.model().provider() returns null, this would result in a NullPointerException instead of the more informative IllegalArgumentException. Consider adding null/empty validation before the switch statement.

The reflection registration for native image support only includes the base Model interface but doesn't include the concrete model implementation classes (DashScopeChatModel, OpenAIChatModel, GeminiChatModel, AnthropicChatModel) that are instantiated by the AgentScopeProducer. These classes may need reflection access for their builders and methods to work properly in GraalVM native images.

The code example shows incorrect syntax for creating a DashScopeChatModel. The builder pattern should use DashScopeChatModel.builder() followed by setter methods, but the example shows new DashScopeChatModel.Builder() followed by ModelConfig.builder() which doesn't match the actual API. The example code won't compile as written.

- Update model names to match config defaults: * gpt-4o-mini → gpt-4 (OpenAI) * gemini-2.0-flash → gemini-2.0-flash-exp (Gemini) - Add null check for model provider validation - Standardize error message formatting (add periods) - Register concrete model classes for GraalVM reflection: * DashScopeChatModel, OpenAIChatModel, GeminiChatModel, AnthropicChatModel - Fix DashScopeChatModel builder syntax in README - Correct directory structure names in README documentation

Add AgentResourceTest with REST-assured tests covering: - Health endpoint verification - Successful chat requests and response formatting - Error handling for empty/null messages - Invalid JSON request handling - Test profile with minimal agent configuration Addresses Copilot review comment about missing test coverage for AgentResource endpoints (PR agentscope-ai#185, line 124).

Add 6 additional test cases to improve code coverage: - Whitespace-only message validation - Long message handling (1000+ characters) - Special characters and Unicode support - Multiline message handling - Health endpoint accessibility - Content-Type header verification This brings the total test count to 12 comprehensive test cases covering edge cases, boundary conditions, and all code paths in the AgentResource class.
