Publish LinkedIn Post

Publish a LinkedIn feed post or long-form article through the local Frevana daemon and Chrome Extension session.

Purpose

This skill uses the Chrome Extension-backed Frevana MCP tool frevana_publish with fixed provider linkedin.

Inputs:

• text (required) - final post text; for article mode this is the article body
• mode (optional) - post or article, defaults to post
• title (optional) - required when mode is article
• cover_image (optional) - article cover image URL or data URL
• format (optional) - text or json, defaults to text
• timeout (optional) - Frevana tool timeout in milliseconds

Publishing is a side effect. Use this skill only when the user explicitly asks to publish.

What This Skill Needs

• final post or article text
• bundled scripts/setup.sh wrapper, which downloads and runs the latest official Frevana setup script
• Frevana local daemon running after setup, default port 12306
• Chrome connected through the Frevana Chrome Extension
• active LinkedIn login in Chrome
• curl
• bash
• python3

This is a Chrome Extension skill. It uses the local daemon and Chrome Extension session.

Execution Order

1. Confirm the user explicitly asked to publish and provided final text.
2. For article mode, require title.
3. Prefer the script over ad hoc frevana call commands.
4. Let the script run bundled scripts/setup.sh before every Frevana tool call.
5. If setup reports Chrome disconnected, stop and tell the user to open Chrome, connect the Frevana extension, and retry.
6. If publishing fails because LinkedIn is unavailable or not logged in, tell the user to log in to LinkedIn in Chrome.
7. Return text output by default. If format is json, return structured JSON with tool, provider, and result.
8. Save output with --output when useful.

Commands

bash <skill-path>/scripts/publish_linkedin_post.sh \
  --text "Just shipped a new feature."

bash <skill-path>/scripts/publish_linkedin_post.sh \
  --mode article \
  --title "My article title" \
  --text-file ./article.txt \
  --cover-image "https://example.com/cover.jpg" \
  --timeout 180000

Fixed Tool Call Shape

The script calls:

frevana call frevana_publish '<json_args>'

The JSON arguments use this shape:

{
  "provider": "linkedin",
  "mode": "article",
  "title": "My article title",
  "text": "Article body...",
  "cover_image": "https://example.com/cover.jpg",
  "timeout": 180000
}

Always send provider: "linkedin". Do not pass unsupported fields. LinkedIn article bodies are typed into LinkedIn's editor; do not expect HTML tags to render as rich formatting.

Notes

• --text and --text-file are mutually exclusive.
• Use plain text for feed posts.
• Use plain text with newlines for LinkedIn articles.
• --mode must be post or article; default is post.
• --title is required for article mode.
• --format must be text or json; default is text.
• --timeout must be a positive integer when provided.
• scripts/setup.sh downloads and executes the latest official setup script from https://raw.githubusercontent.com/FinpeakInc/frevana-cli-releases/refs/heads/main/skills/frevana/scripts/setup.sh.
