Create Goose Graphics Format

Authors a new graphics format and publishes it to the central Gooseworks library via npx gooseworks formats publish. The output is a working directory with a gooseworks-format.json manifest plus at least one rendered example PNG paired with an existing style.

When to use this skill

Use when the user wants a new named format with its own content rules — a story cover, a podcast cover, a square testimonial — that maps to one of the seven built-in canvas sizes (carousel, infographic, slides, poster, story, chart, tweet). The new format defines new rules and a new slug; it inherits dimensions from one of those canvases.
