# Agent skill (/docs/agent-skill)



Install the skill in your current project with the [skills.sh CLI](https://skills.sh/docs/cli):

```bash title="Terminal"
npx skills add opencoredev/sandbox-sdk --skill sandbox-sdk
```

The CLI detects supported coding agents and puts the skill in their project-level skill directories. Add `--global` if you want it available in every project.

```bash title="Terminal"
npx skills add opencoredev/sandbox-sdk --skill sandbox-sdk --global
```

The skill tells an agent how to choose a provider, clean up sessions, check optional capabilities, and find the right reference page without loading the entire docs site.

Review the [skill source](https://github.com/opencoredev/sandbox-sdk/blob/main/skills/sandbox-sdk/SKILL.md) before installing it.
