Skill Validator

Purpose and Intent

The

skill-validator
is the primary quality control tool for this repository. It ensures that every AI Agent Skill is "machine-consumable" by validating it against the
agentskills.io
standard and the repository's
AGENTS.md
rules.

When to Use

  • During Development: Run this skill every time you create or modify a skill.
  • CI/CD Integration: Automatically block Pull Requests that contain non-compliant skill definitions.
  • Repository Audits: Periodically scan the entire
    agent-skills/
    directory to ensure long-term compliance as specifications evolve.

When NOT to Use

  • Code Logic Validation: This tool does not "run" the skills or verify their internal logic; it only validates the "contract" (the YAML and Markdown).

Error Conditions and Edge Cases

  • Invalid YAML: If
    skill.yaml
    cannot be parsed, the validator will fail immediately with a syntax error.
  • Missing Required Fields: Any missing field defined in the
    agentskills.io
    specification will result in
    is_valid: false
    .
  • Empty Directories: Folders in
    agent-skills/
    that do not contain a
    skill.yaml
    will be flagged as invalid skills.

Security and Data-Handling Considerations

  • ReadOnly Access: The skill only requires read permissions for the target directory.
  • No External Calls: Validation is performed locally using the embedded schema rules.
