Internal development tool that validates all SKILL.md and agent .md files against the Claude Code spec. Checks frontmatter completeness, field validity, allowed-tools presence, line count, hardcoded paths, and description quality. Use when the user says "lint skills", "validate skills", "check skill quality", "run the linter", "are my skills valid", or before shipping changes to the skills repo.
Validates SKILL.md files against the agentskills.io standard, checking YAML frontmatter, required sections, line count limits, procedure format, and registry sync. Use before merging new or modified skills.
