validate-output

Validate marketing content against a structural schema — required sections, word counts, markdown formatting, placeholder text (TBD, lorem ipsum, unfilled variables), CTA-topic consistency, and SEO structure — returning a pass/fail checklist with fix instructions. Eight built-in schemas plus custom JSON schemas; auto-detects the schema when none is named. Triggers on "/digital-marketing-pro:validate-output", "check this post against the blog schema", "is this email structurally ready to ship", "scan for leftover placeholders", "why does this draft feel incomplete". Runs output-validator.py and reads brand templates and custom schemas; complements /digital-marketing-pro:eval-content, which judges quality rather than structure.
