Architecture

Thin Wails shell wiring ecosystem packages via core.Core dependency injection. Three operating modes:

GUI Mode (default)

main() → Wails 3 application with embedded Angular frontend, system tray (macOS: accessory app, no Dock icon). Core framework manages all services:

• display (core/gui) — window management, webview automation, 74 MCP tools across 14 categories
• MCP (core/mcp) — Model Context Protocol server with file ops, brain subsystem, GUI subsystem
• IDE bridge (core/mcp/pkg/mcp/ide) — WebSocket bridge to Laravel core-agentic backend
• WS hub (core/go-ws) — WebSocket hub for Angular frontend communication

MCP Mode (--mcp)

core-ide --mcp → stdio MCP server for Claude Code integration. No GUI, no HTTP. Configure in .claude/.mcp.json:

{
    "mcpServers": {
        "core-ide": {
            "type": "stdio",
            "command": "core-ide",
            "args": ["--mcp"]
        }
    }
}

Headless Mode (no display or gui.enabled: false)

Core framework runs all services without Wails. MCP transport determined by MCP_ADDR env var (TCP if set, stdio otherwise).

Frontend

Angular 20+ app embedded via //go:embed. Two routes: /tray (system tray panel, 380x480 frameless) and /ide (full IDE layout).

Configuration

# .core/config.yaml
gui:
  enabled: true          # false = no Wails, Core still runs
mcp:
  transport: stdio       # stdio | tcp | unix
  tcp:
    port: 9877
brain:
  api_url: http://localhost:8000
  api_token: ""          # or CORE_API_TOKEN env var

Environment Variables

Variable	Default	Purpose
CORE_API_URL	http://localhost:8000	Laravel backend WebSocket URL
CORE_API_TOKEN	(empty)	Bearer token for Laravel backend auth
MCP_ADDR	(empty)	TCP address for MCP server (headless mode)

Workspace Dependencies

This module uses a Go workspace (~/Code/go.work) with replace directives for sibling modules:

• ../go → forge.lthn.ai/core/go
• ../gui → forge.lthn.ai/core/gui
• ../mcp → forge.lthn.ai/core/mcp
• ../go-config → forge.lthn.ai/core/go-config
• ../go-ws → forge.lthn.ai/core/go-ws
