 3. Keep read scopes separate: `asset.list` is the current project manifest, `asset.library.list` is the signed-in account library, and the web project's canvas resource read model is the authoritative canvas list. The account library is not the complete canvas list.
 4. Use `canvas.asset_import` for safe account/canvas asset IDs or project-relative local paths. The client rechecks ownership and validates bytes; host absolute paths require native UI file-picker authorization.
 5. When the user explicitly asks to create or derive video, character animation, sound effect, or background music, call `agc_create_or_derive_resource`. Use `create` only for video/audio without a source and `derive` with a registered `sourceLocalAssetId`; character animation is always derived from an image. Keep `prompt` inside the per-kind limit that the client really enforces: background music at most 140 characters, sound effect at most 1900, video and character animation at most 4000. A longer prompt is rejected before submission, so write the short version first instead of retrying the same text.
-6. When the user explicitly asks to remove an image background, call `agc_remove_background` with a registered image `sourceLocalAssetId` and `assetName`. Optional `backgroundMode` is `complex` (semantic foreground segmentation; default) or `flat` (solid-colour background removal). Prefer `flat` when the background is known to be solid. Only `flat` accepts optional `screenColor`: `auto`, `#RRGGBB`, or omitted for automatic detection by the service. Do not select a colour on behalf of `auto`. The client requires the signed-in account, owns canvas/folder context and task identity, waits for the accepted operation, downloads and registers the completed local asset, and preserves the operation for recovery when the remote result is not yet known.

 `prompt` limits are per kind and are enforced before any paid submission: background music accepts 1-140 characters, sound effect 1-1900, video and character animation 1-4000, and image editing (`agc_edit_image`) 1-32000.

The client resolves the formal source resource, canvas/folder context, stable operation identity, idempotency key, and authenticated request. Ordinary account mode maps the External v1 shaped route to `/api/editor/images/background-removals`; ExternalDeveloper mode uses `/api/external/v1/editor/images/background-removals`. Mode and colour are part of request identity. After acceptance, the client polls the authenticated generation status route, downloads the completed media, and commits it to the local manifest.
