Link Validator

Validates markdown links in Claude Code skills for portability across installation locations.

The Problem

Skills with absolute repo paths break when installed elsewhere:

Path TypeExampleWorks When Installed?
Absolute repo/skills/foo/SKILL.mdNo - path doesn't exist
Relative./references/guide.mdYes - always resolves
Relative parent../sibling/SKILL.mdYes - always resolves

When to Use This Skill

  • •Before distributing a skill/plugin
  • •After creating new markdown links in skills
  • •When CI reports link validation failures
  • •To audit existing skills for portability issues
