HTML Structure Validate Skill

Purpose

This skill is a BLOCKING quality gate that ensures generated HTML meets minimum structural requirements. It is the first deterministic validation of probabilistic AI-generated output.

The skill checks:

• HTML5 compliance - Proper DOCTYPE, tags
• Tag closure - All tags properly closed
• Required elements - Meta tags, stylesheet links
• Well-formedness - Valid structure

If validation fails, the pipeline STOPS and triggers a hook to notify the user.

This enforces the principle: Python validates, ensuring deterministic quality.
