openskills MCP — Anwendungsfälle, Installieren & Live-Demo

Warum nutzen

Hauptfunktionen

Rust runtime — fast, predictable
TS and Python bindings for embedding into any agent
Progressive disclosure: metadata → body → scripts only when needed
Sandboxing via Seatbelt (macOS) and experimental WASM
Cross-agent: not tied to Claude Code

Wählen Sie Ihren Client

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "openskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/Geeksfino/openskills",
        "~/.claude/skills/openskills"
      ],
      "_inferred": true
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "openskills-skill": {
      "command": "git",
      "args": [
        "clone",

        "~/.claude/skills/openskills"
      ],
      "_inferred": true
    }
  }
}

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "openskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/Geeksfino/openskills",
        "~/.claude/skills/openskills"
      ],
      "_inferred": true
    }
  }
}

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "openskills-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/Geeksfino/openskills",
        "~/.claude/skills/openskills"
      ],
      "_inferred": true
    }
  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "openskills-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/Geeksfino/openskills",
        "~/.claude/skills/openskills"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

{
  "context_servers": {
    "openskills-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/Geeksfino/openskills",
          "~/.claude/skills/openskills"
        ]
      }
    }
  }
}

In context_servers hinzufügen. Zed lädt beim Speichern neu.

claude mcp add openskills-skill -- git clone https://github.com/Geeksfino/openskills ~/.claude/skills/openskills

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: openskills

How to embed Agent Skills into your own agent runtime

👤 Engineers building custom LLM agents ⏱ ~120 min advanced

Wann einsetzen: You're writing an agent from scratch and want a skill system that already understands SKILL.md.

Voraussetzungen

Rust toolchain (for building) or prebuilt binding — rustup install stable; or use the TS/Python binding
Repo cloned — git clone https://github.com/Geeksfino/openskills ~/.claude/skills/openskills

Ablauf

Install the binding

Install the openskills Python or TS binding and point it at my skills directory.✓ Kopiert

→ Runtime loaded; skills enumerated
Expose to your agent

Wire the runtime into my agent's planner so it considers skills at each step.✓ Kopiert

→ Agent has a SkillRegistry abstraction
Run sandboxed

Enable Seatbelt sandboxing for skill scripts on macOS.✓ Kopiert

→ Skill scripts run under sandbox profile

Ergebnis: Your custom agent can load and run SKILL.md bundles like Claude Code does.

Fallstricke

Loading all scripts at startup kills memory — Rely on progressive disclosure — metadata first
Sandbox denies legitimate operations — Audit the sandbox profile; narrow-then-widen rather than default-deny everything

Kombinieren mit: filesystem

Run a skill in isolation to test it outside Claude Code

👤 Skill authors who want cross-agent validation ⏱ ~45 min intermediate

Wann einsetzen: You want to prove your skill works without the specific harness of Claude Code.

Ablauf

Load the skill

Load ~/.claude/skills/my-skill/ with openskills and print its metadata.✓ Kopiert

→ Parsed frontmatter + body
Invoke with a prompt

Feed it a sample task and observe what would get loaded.✓ Kopiert

→ Disclosure trace: what the agent would see

Ergebnis: Confidence your skill behaves portably.

Fallstricke

Skill depends on Claude Code internals — Refactor the skill to rely only on the public SKILL.md interface

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

openskills-skill + skill-optimizer-skill

Validate skills portably before optimizing them

Load the skill with openskills, then hand off to skill-optimizer for patch suggestions.✓ Kopiert

openskills-skill + filesystem

Operate on the skills directory directly

List all SKILL.md in ~/.claude/skills/, summarize each.✓ Kopiert

Werkzeuge

Was dieses MCP bereitstellt

Werkzeug	Eingaben	Wann aufrufen	Kosten
skill-loader	skills dir	Agent startup	minimal
progressive-disclosure	skill id + stage	During agent reasoning	minimal
sandbox-runner	script + policy	Any time a skill spawns a subprocess	script runtime

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: none
Tokens pro Aufruf: runtime is prompt-light; you control what's disclosed
Kosten in €: free, open source
Tipp: Keep progressive disclosure on — loading every script upfront blows context

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: none at runtime level

Datenabfluss: none beyond what scripts themselves do

WASM sandboxing is experimental — don't rely on it for adversarial scripts
Seatbelt profiles should be tightened per your use case

Fehlerbehebung

Häufige Fehler und Lösungen

Binding import fails

Ensure the native binary matches your platform; rebuild from source if needed.

Sandbox blocks expected syscalls

Iterate on the Seatbelt profile; log denials to find the right allow list.

Alternativen

openskills vs. andere

Alternative	Wann stattdessen	Kompromiss
Claude Code native skill loader	You're only running inside Claude Code	No cross-agent portability
