@gmlewis, @alexandear, @Not-Dhananjay-Mishra I’ve made all the recommended changes and addressed the review comments.
Could you please take another look at this PR ?

Thank you!

I apologize for not catching this sooner, but it looks like we need a new initialism ("MCP") to be added to line 424 of tools/structfield/structfield.go (in sorted order) and then update this line as well. Note that json.RawMessage is already a reference type (it is a byte slice) and there is no need for a pointer here.

So this line needs to be:

Suggested change

	McpConfiguration *json.RawMessage `json:"mcp_configuration"`
	MCPConfiguration json.RawMessage `json:"mcp_configuration"`

type CopilotCloudAgentConfiguration struct {
	MCPConfiguration                      json.RawMessage                `json:"mcp_configuration"`
	EnabledTools                          *CopilotCloudAgentEnabledTools `json:"enabled_tools"`
	RequireActionsWorkflowApproval        bool                           `json:"require_actions_workflow_approval"`
	IsFirewallEnabled                     bool                           `json:"is_firewall_enabled"`
	IsFirewallRecommendedAllowlistEnabled bool                           `json:"is_firewall_recommended_allowlist_enabled"`
	CustomAllowlist                       []string                       `json:"custom_allowlist"`
}

@gmlewis I made all the changes but it is still failing?

Ah, yes, you may need to delete the old linters in the bin subdirectory and then try again.
