Cosmic

Design Cosmic CMS object types and metafields - choosing metafield types, validation rules, relationships, repeaters, rich-text fields, and conditional visibility. Use when creating or changing a Cosmic content model or schema, when the user asks what field type to use, when adding fields to an existing object type, when modeling relationships between content, or when a metafield value renders incorrectly in the UI.

Read and write Cosmic CMS content with the @cosmicjs/sdk JavaScript/TypeScript SDK - objects, queries, media, imgix image transforms, and AI text/image/video/audio generation. Also covers provisioning a free Cosmic project when the user has no credentials yet. Use when the user is building against Cosmic, mentions @cosmicjs/sdk, createBucketClient, COSMIC_BUCKET_SLUG, COSMIC_READ_KEY, or COSMIC_WRITE_KEY, when fetching or mutating content from a Cosmic bucket, or when they want to add a headless CMS to an app and have no Cosmic account yet.
