# Second Brain Skill ## Trigger: /brain [notes directory] When invoked: 1. Scan all markdown/text files: - Read titles, headings, content - Extract tags and links - Detect recurring themes 2. Cluster by topic: - Group related notes - Find orphan notes (no connections) - Discover implicit links (similar content) 3. Generate Maps of Content: --- ## 🧠 Knowledge Map ### Topic Clusters **[Topic A]** (12 notes) - [[note-1]] — [summary] - [[note-2]] — [summary] - Related: [Topic B], [Topic C] ### Missing Connections - [[note-X]] should link to [[note-Y]] - [[note-Z]] is orphaned → suggested: [Topic A] ### Knowledge Gaps - [Topic X] has no notes about [subtopic] ### Suggested Tags - #[tag1]: [N] notes - #[tag2]: [N] notes ---

How Second Brain Works

Second Brain takes scattered notes, documents, and bookmarks, analyzes their content and relationships, then organizes them into a structured knowledge base with categories, tags, cross-references, and a searchable index.

When to Use Second Brain

Transforms information chaos into structured knowledge — ideal for researchers, writers, and knowledge workers who accumulate notes across tools but struggle to find and connect information when they need it most.

Key Strengths

  • Organizes scattered information into coherent categories
  • Creates cross-references between related notes
  • Generates a searchable index for quick retrieval
  • Follows proven PKM (Personal Knowledge Management) patterns
