jeremylongshore/claude-code-plugins-plus-skills

Plugins activate through frontmatter-based trigger phrases in markdown SKILL.md files, allowing Claude Code to automatically invoke relevant tasks without explicit slash commands. The marketplace supports three plugin types—AI instruction plugins (markdown-only), MCP Server plugins (Node.js processes via Model Context Protocol), and SaaS skill packs for platforms like Deepgram and Linear—managed through the CCPI CLI or Claude's native `/plugin` commands. Includes production orchestration patterns and learning labs documenting multi-agent workflow architecture with empirical validation guides.
