About

Link Check

Validate wiki-links and find orphaned notes.

What It Checks

| Issue | Description | Impact | |-------|-------------|--------| | Broken links | [[Note]] where Note.md doesn't exist | Navigation fails | | Orphaned notes | Files with no incoming links | Hard to discover | | Ambiguous links | Multiple files match the link | Unpredictable resolution |

Workflow

  1. Scan for all wiki-links
  • Find [[...]] patterns in all .md files
  • Extract link targets
  1. Validate each link
  • Check if target file exists
  • Check for ambiguous matches
  • Track which files link to what
  1. Find orphaned notes
  • Files that no other file links to
  • Exclude expected orphans (CLAUDE.md, templates, etc.)
  1. Generate report
  • Broken links with source files
  • Orphaned notes list
  • Link statistics

Search Patterns

# Find all wiki-links
Grep pattern="\[\[[^\]]+\]\]" path="{vault}" glob="*.md"

# Find links to specific note
Grep pattern="\[\[Note Name\]\]" path="{vault}" glob="*.md"
