LinkedIn Announcement Generator
Overview
This skill automates the creation of professional LinkedIn announcements for intelligent textbooks. It analyzes book metrics from the docs/learning-graph/ directory, gathers statistics about chapters, concepts, and educational resources, and generates engaging announcement text with relevant hashtags and links to the published site.
The announcements are designed to highlight the scope and completeness of the textbook, showcase its educational features, and attract educators, students, and learning professionals to the content.
When to Use This Skill
Use this skill when:
Publishing a completed intelligent textbook to GitHub Pages
Announcing major milestones (e.g., "First 10 chapters complete!")
Promoting updated or newly added content
Sharing the textbook with the educational technology community
Preparing social media posts for course launches
Creating announcements for conference presentations or workshops
Building awareness for open educational resources
Prerequisites
The intelligent textbook project should have:
A docs/learning-graph/book-metrics.md file containing textbook statistics
A mkdocs.yml file with site_name, site_url, and site_description
Deployed site on GitHub Pages (or another hosting platform)
Optional: docs/learning-graph/chapter-metrics.md for chapter-level details
Optional: docs/course-description.md for audience and topic information
Workflow
Step 1: Gather Book Metadata
Extract key information from the project configuration:
Read mkdocs.yml to get:
site_name - Title of the textbook
site_url - Live site URL (typically GitHub Pages)
site_description - Brief description of the textbook
