Cross-Post to Social Media

Cross-post content to LinkedIn, Twitter/X, and Slack. Can be used standalone or called from other skills (e.g., notion-article).

Your Task

1. Gather context from one of these sources:
   • An article URL passed as argument (e.g., a Notion page URL)
   • A file path passed as argument
   • Current conversation context
2. Ask the user using AskUserQuestion (can be combined in a single prompt):
   • Which platforms to cross-post to (multiSelect): LinkedIn, Twitter/X, Slack
   • Which language to write the posts in: French, English

   Only proceed with platforms the user selects. Write all posts in the selected language.

3. Generate platform-appropriate content in the selected language for each selected platform

4. Show the user a preview of each post before publishing

5. Sensitive-terms scan (required, before any posting). Write each final post to a temp file and run ~/dev/claude/scripts/scan_sensitive.sh <files>:
   • Exit 0 → proceed.
   • Exit 1 → show the matches and do not post. LinkedIn/X are public: rewrite around the term, or post only after the user explicitly clears that specific match. Slack is internal: ask the user whether the match is acceptable there.
   • Exit 2 (terms list unreachable) → fail closed: report it and don’t post until the scan can run.
6. Post using the corresponding MCP tool and report results with links

Example:

I spent last week deep-diving into MCP servers and how they can automate content distribution.

The result? A workflow that publishes my articles to Notion, then cross-posts to LinkedIn, Twitter, and Slack—all from a single command.

TIL you can set up MCP servers to automate posting across Slack, LinkedIn, and Twitter from Claude Code.
