Documentation

README

Excerpt

Check Links Skill

Finds broken [[wiki-links]] across your vault by extracting link targets and verifying that each target file exists. Read-only — never modifies files.

Usage

/check-links

Or ask:

"Check for broken links in my vault"
"Find dead wiki-links"
"Are there any broken links?"

How to Execute

Step 1: Extract all wiki-links

Use Grep to find all [[...]] patterns in markdown files:

Grep:
  pattern: "\\[\\[([^\\]|]+)"
  glob: "*.md"
  output_mode: content
  -n: true

This captures the link target (before any | alias). Exclude .claude/ and .obsidian/ directories from results.

Step 2: Build unique target list

This is the opening of the README. Read the full README on GitHub.
