  "skill_md_contents": "---\nname: formats-global\ndescription: See top video formats across all of Sandcastles\n---\nShow me the top video formats working across all of Sandcastles, beyond my watchlist. Use the `top_formats` tool with `scope: \"all\"` to retrieve high-performing analyzed videos globally, then group them by `format_category`, summarize what's distinctive about each group, and identify which formats are dominant or rising. Cite 2-3 example videos per format with their Sandcastles links.\n\nAlways present the results as an HTML artifact, never as a plain text reply. Make it beautiful, visual, and minimalist, styled in the Sandcastles theme: a white background, generous white space, clean sans-serif type, the primary blue #3B82F6 for accents, links, and highlights, and the Sandcastles logo (https://app.sandcastles.ai/logo-banner-light-mode.svg) in the header. Show each video as a card with its `thumbnail`, the creator's channel thumbnail as a round avatar, the creator's handle, the key metrics, and a link to its `sandcastles_url`. Lead with the insights, then the videos that support them.\n"
