Check Skill Formatting

Validate skill files against formatting conventions. Catches preprocessing hazards, placeholder violations, and frontmatter issues.

Steps

1. Load the /skillcheck skill (runs preprocessing linter)
2. Run the placeholder linter to find [string] patterns that should use { string } convention
3. Run the fence linter to find bare code fences and nesting issues
4. Run the relative paths linter to find ../ references that should use ${CLAUDE_PLUGIN_ROOT}
5. Review findings and fix violations

Placeholder Linter

Scan markdown files for [string] patterns that aren't markdown links or file references:
