# Standalone CLI

> Inspect and validate local documents without opening the desktop editor.

The `skydream` command-line tool is separate from the desktop app. It works on
local files and does not require a cloud account or a running editor. Public CLI
downloads are not yet published; current qualification covers Linux x86-64.

After obtaining the CLI for your platform, start with:

```bash theme={null}
skydream --help
skydream version
```

Use an explicit document folder when inspecting a local EPUB:

```bash theme={null}
skydream --root /path/to/documents inspect example.epub
skydream --root /path/to/documents validate example.epub
```

Inspection reports supported structure and unsupported content. Validation checks
the supported Skydream profile; it is not a claim to support every EPUB feature.

Some CLI write operations support a narrower document profile than the visual
editor. A refused operation protects unsupported content. Do not work around
that refusal by removing formatting or replacing the original file.

The CLI is not a replacement for account setup, cloud recovery or the desktop
installer's bundled background service.
