Make the example concrete
Give the example a category, product, audience, and approved facts. Vague placeholder copy does not test whether the Skill can produce usable marketing work.
Rebuild the creative direction
Competitor research can reveal a task category such as social campaign or Amazon image set. The Retake example must create a new brand, copy system, composition, imagery, and platform mapping.
Keep provenance with every asset
Store the generation prompt, source boundary, dimensions, checksum, alt text, and QA result. A screenshot in a folder is not enough to publish a catalog item.
Keep examples separate from customer evidence
An example can demonstrate a workflow or deliverable, but it cannot become a testimonial, review, endorsement, or claimed customer result.
