Principais recursos

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

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

O Continue usa um array de objetos de servidor em vez de um map.

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

Casos de uso

Usos do mundo real: openskills

How to embed Agent Skills into your own agent runtime

👤 Engineers building custom LLM agents ⏱ ~120 min advanced

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

Pré-requisitos

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

Fluxo

Install the binding

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

→ Runtime loaded; skills enumerated
Expose to your agent

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

→ Agent has a SkillRegistry abstraction
Run sandboxed

Enable Seatbelt sandboxing for skill scripts on macOS.✓ Copiado

→ Skill scripts run under sandbox profile

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

Armadilhas

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

Combine com: filesystem

Run a skill in isolation to test it outside Claude Code

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

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

Fluxo

Load the skill

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

→ Parsed frontmatter + body
Invoke with a prompt

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

→ Disclosure trace: what the agent would see

Resultado: Confidence your skill behaves portably.

Armadilhas

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

Combinações

Combine com outros MCPs para 10× de alavancagem

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.✓ Copiado

openskills-skill + filesystem

Operate on the skills directory directly

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

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
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

Custo e limites

O que custa rodar

Cota de API: none
Tokens por chamada: runtime is prompt-light; you control what's disclosed
Monetário: free, open source
Dica: Keep progressive disclosure on — loading every script upfront blows context

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: none at runtime level

Saída de dados: 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

Solução de problemas

Erros comuns e correções

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.
