Obsidian Tag Criteria

Defines criteria for tagging Obsidian notes. Tags should only be assigned when content clearly matches the criteria.

Judgment Rules

1. Clarity Principle: Only assign tags when content clearly matches the definition
2. Multiple Tags Allowed: Assign all applicable tags (e.g., arXiv paper -> #papers #arxiv)
3. No Tag is OK: Do not assign any tag if none clearly match
4. Preserve Existing Tags: Do not delete or modify existing tags
5. Avoid Duplicates: Do not add tags that already exist
6. Folder Path Rule: If the file path contains a folder name semantically matching a tag (e.g., 3d-reconstruction/), automatically apply that tag
   • Match folder names to tag names (with or without # prefix, hyphens normalized)
   • When ambiguous, prefer the more specific tag or skip folder-based tagging
   • Examples:
     • 3d-reconstruction/note.md -> #3d-reconstruction
     • papers/summary.md -> #papers
     • ai-tools-info/guide.md -> #ai-tools
