XCPSSKPlugin

XCPSSKPlugin is the Xcode developer plug-in bundle target (XCPSSKPlugin.xcplugin) that integrates SovereignSurvivalKit with Apple Xcode Coding Intelligence via the Agent Client Protocol (ACP) and Model Context Protocol (MCP).

1. Xcode Intelligence Preferences Configuration

To configure SovereignSurvivalKit as an ACP Coding Agent in Xcode (Xcode Settings > Intelligence > Add an ACP Agent), use the following configuration parameters:

┌────────────────────────────────────────────────────────────────────────┐
│ Add an ACP Agent                                                       │
├───────────────────────┬────────────────────────────────────────────────┤
│ Name                  │ SovereignSurvivalKit                           │
├───────────────────────┼────────────────────────────────────────────────┤
│ Executable            │ /usr/local/bin/SSK_StorageHost                 │
├───────────────────────┼────────────────────────────────────────────────┤
│ Interpreter           │ (Leave Blank)                                  │
├───────────────────────┼────────────────────────────────────────────────┤
│ Arguments             │ acp-agent                                      │
├───────────────────────┼────────────────────────────────────────────────┤
│ Environment Variables │ (Leave Blank)                                  │
└───────────────────────┴────────────────────────────────────────────────┘

Field Breakdown

Field	Configuration Value	Description
Name	SovereignSurvivalKit (or SSK_StorageHost)	Display identifier in Xcode's agent list.
Executable	/usr/local/bin/SSK_StorageHost	Path to the canonical agent binary installed on the host.
Interpreter	(blank / optional)	SSK_StorageHost is a compiled native Mach-O binary and does not require a script interpreter.
Arguments	acp-agent	Single CLI argument directing SSK_StorageHost to launch the external ACP/MCP facade.
Environment Variables	(none)	Stored configuration and vault paths are managed securely by the SSKVaultHost daemon.

Alternative Executable Paths

If you are developing or running outside the default /usr/local/bin installation:

• Installed Application Bundle: /Applications/SSKVaultHost.app/Contents/MacOS/SSK_StorageHost
• Installed Xcode Plug-in Resource: ~/Library/Developer/Xcode/Plug-ins/XCPSSKPlugin.xcplugin/Contents/Resources/SSK_StorageHost
• Local Build Products: dist/Products/usr/local/bin/SSK_StorageHost

2. Architecture & Execution Flow

When Xcode Coding Intelligence initiates an ACP agent session, communication flows across strict system boundaries:

Xcode Coding Intelligence
  │ (stdio JSON-RPC)
  ▼
SSK_StorageHost acp-agent (External MCP Facade)
  │ (Mach XPC via com.ssk.vaulthost)
  ▼
SSKVaultHost Daemon (Validates Audit Token & Code Signature)
  │ (Private Worker Process)
  ▼
SSK_DocGen (Isolated Resource Worker)
  │ (Descriptor-Relative Read)
  ▼
Approved Documentation Ledger (SSK_Ledger_Vault)

3. Plug-in Files

• XCPSSKPlugin.swift: Plug-in entry point that locates SSK_StorageHost in the bundle resources and binds stdin, stdout, and stderr.
• ssk-intelligence-plugin.json: MCP descriptor declaring command ./Resources/SSK_StorageHost with arguments ["acp-agent"].
• Info.plist: Bundle manifest declaring CFBundlePackageType = BNDL and XcodePluginBaseClass = XCPSSKPlugin.
