Obsidian CLI Inspector - A local-first, read-only CLI/TUI for Obsidian vaults

ABOUT:
    This tool helps you inspect, search, and navigate your Obsidian vault from the terminal.
  All data is stored locally in a SQLite database for fast, offline access.

USE CASES:
  • Search: Find notes quickly with full-text search across your entire vault
  • Link Analysis: Discover backlinks, forward links, and unresolved references
  • Tag Management: Filter and organize notes by tags with AND/OR logic
  • Graph Exploration: Visualize note relationships and connection depths
  • Content Quality: Identify bloated notes that may need refactoring
  • Related Notes: Get AI-style suggestions for notes you might want to link
  • Scripting: Integrate with shell scripts and automation workflows
  • Interactive TUI: Browse your vault in a terminal user interface

WORKFLOW:
  1. Run 'init init' to set up the database
  2. Run 'index index' to scan and parse your vault
  3. Use search commands (notes, backlinks, tags, etc.)
  4. Re-run 'index index' periodically to catch changes

CLI STRUCTURE:
  obsidian-cli-inspector <group> <function> [args...]

  Groups:
    init     - Database initialization
    index    - Vault indexing (scan, status)
    search   - Search and retrieval (notes, backlinks, links, tags, unresolved)
    graph    - Graph operations (neighbors, paths, centrality, components)
    analyze  - Content analysis (bloat, related, similar, quality)
    diagnose - Diagnostics (orphans, broken-links, conflicts)
    view     - Display commands (stats, describe, health)

EXAMPLES:
  # Initialize and index your vault
  obsidian-cli-inspector init init
  obsidian-cli-inspector index index

  # Search for notes containing 'rust'
  obsidian-cli-inspector search notes rust --limit 10

  # Find all notes linking to 'Project Ideas'
  obsidian-cli-inspector search backlinks "Project Ideas"

  # List all notes tagged with 'work'
  obsidian-cli-inspector search tags work

  # Find large notes that might need splitting
  obsidian-cli-inspector analyze bloat --threshold 100000

  # Launch interactive mode
  obsidian-cli-inspector tui

CONFIG:
  Place config at ~/.config/obsidian-cli-inspector/config.toml
  Specify vault path and database location there.
