The instructions your model reads when the skill loads.
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.
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.
Custom canvas dimensions are not supported. If the user wants a
canvas size that isn't in the seven built-ins (e.g. LinkedIn banner
1584×396, US Letter 2550×3300), tell them honestly — that requires a
code change to the goose-graphics skill pack's FORMAT_CONFIGS and is
out of scope for this skill. Suggest the closest existing canvas
instead.
Always check first: run npx gooseworks formats list (or formats search "banner" etc.) to see whether a community-published format already covers the
use case. If one fits, just use it via the regular goose-graphics flow.
