# linkedin.text.max_graphemes

> LinkedIn caps post commentary at 3000 graphemes. Emoji-aware.

## What it checks

`countGraphemes(text) <= 3000`.

## Why 3000

LinkedIn's `/rest/posts` commentary cap is 3000 graphemes — emoji and ZWJ sequences count as 1 character, matching our counter. The cap is documented in LinkedIn's Versioned API docs.

## Remediation

Trim the post. Use grapheme-aware splitting — see [`bluesky.text.max_graphemes`](/preflight/bluesky-text-max_graphemes) for example code.
