generate_linkedin_hooks

  }
}

preview_linkedin_post

Return a link to an approximate preview of the post in the LinkedIn feed on mobile and desktop, including about where "see more" cuts it. Pass author_name and author_headline when you know them. Opening the link saves and publishes nothing. The post text travels in the link, so share it only with people who should read the draft.

read-only

Argument	Type	Description
post*	string	The post text.
author_name	string	Name shown on the preview.
author_headline	string	Headline shown under the name.

Input schema (JSON)

  "required": [
    "post"
  ],
  "properties": {
    "post": {
      "type": "string",
      "minLength": 1,
      "description": "The post text."
    },
    "author_name": {
      "type": "string",
      "maxLength": 80,
      "description": "Name shown on the preview."
    },
    "author_headline": {
      "type": "string",
      "maxLength": 220,
      "description": "Headline shown under the name."
    }
  }
}

style_linkedin_text

Restyle a short piece of text with Unicode letters that keep their look when pasted into LinkedIn (bold, italic, bold italic, serif, cursive, strikethrough, underline). Use sparingly; screen readers may read styled letters poorly.

read-only

Argument	Type	Description
text*	string	The words to restyle.
style	string	Style to apply.

Input schema (JSON)

{
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
