# `uploadSkill()`

Uploads a skill (a bundle of files) to a provider and returns a `ProviderReference` that can be used in subsequent inference calls.

```ts
import { uploadSkill } from 'ai';
import { anthropic } from '@ai-sdk/anthropic';
import { readFileSync } from 'fs';

const { providerReference } = await uploadSkill({
  api: anthropic.skills(),
  files: [
    {
      path: 'my-skill/SKILL.md',
      content: readFileSync('./SKILL.md'),
    },
  ],
  displayTitle: 'My Skill',
});
```
