Validate Skill

validate-skill

Validate that a skill conforms to waldronlab standards. Uses generic validators (markdownlint, yamllint) for basic checks, then adds waldronlab-specific validation for platform-agnostic compliance and repository conventions.

Usage

Invoke this skill to validate a skill file:

• "Validate this skill"
• "Check if skills/[skill-name]/SKILL.md meets standards"

Prerequisites

• Target skill file exists at skills/{skill-name}/SKILL.md
• Optional: markdownlint and yamllint installed

Process

1. Locate Target Skill: Determine the skill to validate from the user's prompt or current directory.
2. Run Generic Validation (Optional): If available, run markdownlint on the file, and validate the YAML frontmatter syntax (e.g., by extracting the frontmatter and running yamllint -d relaxed on it).
3. Validate Repository Standards: Check the file against the requirements in AGENTS.md and SKILL_STANDARD.md.
   • Ensure the YAML frontmatter contains required fields and no prohibited fields (platforms, triggers).
   • Check that the structure matches the standard format.
   • Verify agent neutrality (no tool references or platform commands in instructions).
   • Confirm it describes a workflow, not just code snippets.
   • Ensure it does not duplicate content from SSOT documents.
4. Generate Validation Report: Produce a summary of passed and failed checks, categorized by CRITICAL, WARNING, and INFO.
5. Suggest Next Steps: Offer to help fix any identified issues.

Output Format

Generate a validation report in markdown format:

# Skill Validation Report: [skill-name]

Examples

Example: Validating a Skill

User: "Check if the analyze-r-package skill meets standards" Agent:

1. Locates skills/analyze-r-package/SKILL.md
2. Runs generic and repository-specific validations
3. Reports results, identifying any CRITICAL or WARNING issues.
