Summary

This PR adds validation for tool settings in the agentic package to ensure tool configurations are checked before use. It prevents invalid or incomplete settings from being accepted, improving reliability and reducing runtime failures.

Why

Invalid tool settings can lead to unexpected behavior or runtime errors that are difficult to diagnose. Validating configuration early provides clearer feedback and ensures only valid tool definitions are executed.

How to review

• Review the tool settings validation logic in the agentic package.
• Verify the validation rules and error handling for invalid configurations.
• Confirm existing valid tool configurations continue to work without changes.

Validation

• Tested with valid tool settings to confirm they are accepted.
• Tested with invalid and incomplete tool settings to verify appropriate validation errors are returned.
• Verified no regressions in the existing tool configuration workflow.
