• The parameter 'requireApproval' is typed as object, which may be ambiguous. Consider using a more specific type (e.g., bool or a custom type) to clarify its intended usage and improve type safety.

            [JsonProperty("require_approval")] object requireApproval)

• The constructor references an undeclared variable 'index'. It is likely that the intended assignment was to use one of the provided constructor parameters (such as 'startIndex'). Please update the assignment to reference the correct variable.

            Index = index;

The removal of the null check that previously threw an ArgumentNullException may allow a null value for ToolNames. Consider adding explicit null validation or a default empty list to prevent potential null reference issues.

Suggested change

	ToolNames = toolNames?.ToList();
	ToolNames = (toolNames ?? new List<string>()).ToList();
