# bluesky.text.non_empty

> Bluesky posts cannot be empty. Whitespace-only text is rejected.

## What it checks

`text.trim().length > 0`. Bluesky requires a non-empty post body — there's no "image-only with no caption" surface like there is on Instagram.

## Why

Bluesky's `app.bsky.feed.post` record requires a `text` field. Sending an empty string or whitespace produces a record that's syntactically valid but semantically broken; Bluesky's appview hides empty posts from feeds.

## Failure response

```json theme={"system"}
{
  "error": {
    "code": "preflight_failed",
    "rule": "bluesky.text.non_empty",
    "platform": "bluesky",
    "message": "Post text cannot be empty.",
    "remediation": "Provide a non-empty text body."
  }
}
```

## Remediation

Send any non-whitespace `text`. If you want a media-only experience, attach the image and use a brief caption like the file name.
