# Skills

Skills are reusable procedures that tell OpenClaw how to perform a class of work safely. They sit above plugins and APIs: a skill selects tools, applies validation and approval boundaries, and specifies what evidence is required.

## Documented relationships

- `bookstack-controlled-sync` uses the BookStack API and requires fresh read-back verification.
- `paperless-ngx` uses the Paperless REST API for document workflows.
- `proxmox-readonly` limits Proxmox work to inventory and health reads.
- `configure-channel`, `add-model-provider` and protected-secret procedures handle setup without exposing credentials.
- Browser, email, voice and control-UI skills use their corresponding plugins or provider tools.

Skills describe procedures, while plugins expose capabilities and services hold the underlying data.
