Canva Designer

Canva

Use the installed canva CLI. Start with canva status. If it reports not_connected, run canva authorize-url and share only the returned connect_url. If the CLI reports outdated OAuth settings, have the user disconnect Canva in Settings and reconnect. Never request tokens in chat.

Run canva list-tools for live schemas and use only tools returned there. Follow their input schemas exactly and include a concise user_intent. hatch_permission_overrides identifies argument-dependent permissions; opening an editing transaction is a write and deleting pages is a delete. Some tools require Canva Pro, Enterprise, or available AI credits.

Save each raw response before parsing. Check result.isError, then read result.structuredContent when present or parse the JSON text block in result.content. Both response forms are valid. A local parsing failure does not mean a mutation failed: recover its response or inspect saved state before continuing. Never repeat a copy, creation, or commit just to obtain its output.

Create designs and images

Use create-design for a new editable layout: social post, infographic, poster, flyer, presentation, document, or sheet. Put all necessary source facts and requested wording in brief; the tool does not inherit chat or connected-source context. Fetch the user-selected source first. For an exact size, state dimensions and orientation in the brief. If supplying format, include the orientation; an ambiguous format may resolve to a square. Pass outline only for a presentation outline the user supplied or approved.

Use generate-image for an explicitly requested standalone image, photo, illustration, artwork, or image of an infographic. Use one MEDIA reference per uploaded source image. This generates an image rather than an editable page layout. Use its returned media_id when editing a generated image again.

create-design cannot apply brand kits or brand templates. For an explicitly on-brand request, use the available legacy generate-design, get-design-candidates, and create-design-from-candidate flow, showing candidates for the user's choice. These tools are otherwise deprecated when create-design is listed; failure of create-design is not permission to fall back. generate-design does not support presentations despite its enum. The legacy outline-review widget and structured presentation generator are not exposed by this CLI. Do not substitute a non-branded generation when a brand-specific presentation workflow is unavailable. A selected brand template can still be copied with create-design-from-brand-template or autofilled.

Creation and layer separation return asynchronous jobs. When no Canva widget is shown (including CLI use), poll the corresponding get-create-design-async-job, get-generate-image-job, or get-separate-image-layers-job. Honor every returned wait interval and updated continuation token. Never start a replacement write because a job is pending. Stop on terminal failure; respect quota and moderation failures. Show completed results using the preview workflow below. For generated images, include the returned Canva upload link with the text Open generated image.

Upload and transform images

For attachments, local files, or generated files up to 256 MiB, use canva upload-file --file <path> --user-intent '<purpose>'. Its approval shows the selected file and an image preview for workspace images. The CLI obtains a single-use upload URL and sends the raw bytes after approval; use the returned resource IDs in later calls. Do not repeat an upload whose outcome is unknown. The low-level create-upload-url flow remains available for larger files: one raw-byte POST with Content-Type: application/octet-stream, no multipart, JSON, or base64. Never retry a consumed upload URL.

upload-asset-from-url and import-design-from-url accept already-public HTTPS sources only. Do not publish local or private files to use those tools. Uploading media does not place it into a design. create-design has no asset input parameter: when exact supplied media must appear, use the editing flow to insert or replace media with its verified Canva ID, then inspect the result.

Use remove-background with an already-uploaded MEDIA reference to produce a new image with transparent alpha. It does not replace the scene or crop the subject. Use separate-image-layers with an uploaded image's asset_id to turn a flat graphic into a new editable design; the original stays unchanged. Verify editable elements with read-design, not appearance alone.
