Markdown Cross-Reference Validator

When to use this skill

Use this skill when the user asks to validate or check cross-references in markdown files. This includes verifying that internal links (e.g., text) point to existing headings, and that file references (e.g., text) point to existing files.

Algorithm & Workflow

Phase 1: Document Preparation

1. Identify target file(s): Determine which markdown file(s) to validate
2. Read content: Load the full markdown document(s) into memory
3. Establish base path: Determine the root directory for relative file references
