fabric-claude

A Claude Code plugin that brings Fabric prompt patterns into Claude Code sessions natively. Claude applies the patterns directly — no separate API key needed.

Features

• /fabric command — Apply any of ~55 curated Fabric patterns to content
• URL fetching — Paste a YouTube or web URL to auto-fetch content
• Obsidian output — Every run saves a note with frontmatter for knowledge base / RAG
• Follow-up suggestions — Contextual pattern recommendations after each run
• Degraded mode — Works with 15 bundled patterns even without Fabric installed

Install
