Read this in: **English** · [فارسی](i18n/fa/README.md).

```bash
npx @velella/offing scan .

For coding agents, install the Agent Skill with one command. It teaches your agent to find, explain, and migrate these findings, and it is listed on [skills.sh](https://skills.sh/velella-sh/offing/offing):

```bash
npx skills add velella-sh/offing
```

Node.js 22 or newer. Start with [Install](INSTALL.md) (npm, Action, MCP, plugins, Docker), then the [90-second demo](DEMO.md) on a deliberately outdated project:

```text
Found 5 lifecycle risks. The most urgent:
  HIGH Unsupported actions/checkout runtime (.github/workflows/ci.yml:9)
  MEDIUM Node.js 18 is end-of-life (package.json:5)
  MEDIUM Node.js 19 is end-of-life (package.json:5)
  …and 2 more below.
```
