      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",

Abre Claude Desktop → Settings → Developer → Edit Config. Reinicia después de guardar.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "swiftui-agent-skill": {

    }
  }
}

Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

Haz clic en el icono MCP Servers de la barra lateral de Cline y luego en "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "swiftui-agent-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ],
      "_inferred": true
    }
  }
}

Mismo formato que Claude Desktop. Reinicia Windsurf para aplicar.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "swiftui-agent-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/twostraws/SwiftUI-Agent-Skill",
        "~/.claude/skills/SwiftUI-Agent-Skill"
      ]
    }
  ]
}

Continue usa un array de objetos de servidor en lugar de un mapa.

~/.config/zed/settings.json

{
  "context_servers": {
    "swiftui-agent-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/twostraws/SwiftUI-Agent-Skill",
          "~/.claude/skills/SwiftUI-Agent-Skill"
        ]
      }
    }
  }
}

Añádelo a context_servers. Zed recarga en caliente al guardar.

claude mcp add swiftui-agent-skill -- git clone https://github.com/twostraws/SwiftUI-Agent-Skill ~/.claude/skills/SwiftUI-Agent-Skill

Un solo comando. Verifica con claude mcp list. Quita con claude mcp remove.

Casos de uso

Usos del mundo real: SwiftUI Agent Skill

Build a settings screen the right way (iOS 17+)

👤 iOS devs ⏱ ~15 min intermediate

Cuándo usarlo: You want a Settings screen that's actually idiomatic for iOS 17+.

Requisitos previos

Server/skill installed and authenticated — See repo README

Flujo

Plan

Using the SwiftUI skill, design a Settings view with sections: Account, Notifications, About. Use @Observable for the view model.✓ Copiado

→ View hierarchy + ViewModel sketch
Code

Write the full file with toggles, NavigationLink to subpages, and a confirmation dialog for sign-out.✓ Copiado

→ Compiles on Xcode 15+

Resultado: Idiomatic SwiftUI you don't have to rewrite next year.

Errores comunes

Don't mix @StateObject with @Observable — Don't mix @StateObject with @Observable — the skill enforces one or the other; follow it.

Coste y límites

Lo que cuesta ejecutarlo

Cuota de API: See provider docs for rate limits
Tokens por llamada: Varies by tool
Monetario: See repo README for pricing details
Consejo: Cache tool results and avoid repeated identical calls.

Seguridad

Permisos, secretos, alcance

Almacenamiento de credenciales: Use environment variables; never commit secrets

Salida de datos: Tool calls go to the provider's API as documented

Resolución de problemas

Errores comunes y soluciones

view doesn't update on state change

Ensure the property is on an @Observable class, not a struct. The skill's checklist covers this.

Verificar: @Observable annotation present

preview crashes

@Observable views need a real instance in #Preview. The skill's examples show the pattern.

Verificar: Preview compiles
