 - Use stable references such as `objectKey`, project resource ID, or asset ID where each operation permits them. Image edit/redraw is stricter: `sourceReferenceId` accepts only a registered project resource ID or asset ID; upload confirmation alone is not enough. Use `/assets/read-url` only for temporary preview/download access.
 - Preserve both warning channels after completion. A general `warning` can coexist with `sliceWarning`; do not discard either.
 - Do not invent missing derivatives. A source-preserved warning means the main source remains usable but requested post-processing failed. A slice warning means the complete transparent sheet is usable but individual slices are absent.
- Icon spritesheet generation accepts `sliceMode="connected-components"` (default alpha-connectivity detection) or `sliceMode="grid"`. Grid mode requires `gridX` and `gridY` (1-32); use `sliceCount` only to constrain connected-component output.
+- Icon spritesheet generation requires an explicit `sliceMode` and has no default. Use `sliceMode="grid"` with the `gridX` and `gridY` the requirement actually names (1-32 each) only for equal grid cells or fixed slots; use `sliceMode="connected-components"` for free-form sheets or an open number of subjects, and constrain the count with `sliceCount` instead of inventing grid dimensions. `connected-components` must not carry `gridX`/`gridY`; an omitted, contradictory, or misapplied declaration returns 400 before billing.
 - For successful `style="pixelArt"`, treat completed-result and nested resource/asset dimensions as the final logical-grid PNG dimensions. They may differ from `size`, `imageSize`, the provider image, and `canvasCompletion.placeholder`; do not rescale or reject the artifact to match those inputs.
 - Keep generated artifacts in the canvas and asset library together. Character animation accepts `assetFolderId` and `assetLabel`; its completed result directly returns the final `assetKind="character-animation"` resource and asset with formal sequence fields. Do not create a duplicate first-frame record.

 The icon-spritesheet primary `referenceId` is intentionally stricter than ordinary image references: it accepts only a current-owner project resource ID or asset ID whose authoritative `assetKind` is `icon-spec`. It does not accept an `objectKey`, URL, Data URL, or Blob URL.

-`sliceMode` controls atlas splitting. Use `"connected-components"` (default) to detect independent opaque regions by alpha connectivity, or `"grid"` with positive `gridX` and `gridY` values (maximum 32 each). `sliceCount` optionally constrains the connected-component result.
+`sliceMode` is required and has no default, so every request must state it. Use `"connected-components"` to detect independent opaque regions by alpha connectivity, or `"grid"` with positive `gridX` and `gridY` values (maximum 32 each) only when the requirement names equal grid cells or fixed slots; the dimensions must come from that requirement. `connected-components` must not carry `gridX`/`gridY`, and `sliceCount` constrains the connected-component result instead of expressing a grid. Omitting `sliceMode`, or contradicting the declared mode with grid dimensions, returns 400 before pricing, enqueueing, or any provider call.

+3. `art-asset-plan` generates transparent `assets/art-spritesheet.png` through icon spritesheet generation, using the same registered art-spec resource ID as `referenceId` plus concrete `iconDescriptions`. `sliceMode` is required and has no default: send `sliceMode: "grid"` with `gridX`/`gridY` only when the requirement itself fixes the slots or names the column/row count, and otherwise send `sliceMode: "connected-components"` (with `sliceCount` when a subject count must be constrained); never invent a grid to express "kinds of assets", and never send `gridX`/`gridY` with `connected-components`.

-For a playable Canvas game, do not stop at generation. Make `code-prototype` depend on `art-asset-plan` and consume the persisted `iconImageSrcs` slices for core players, blocks or targets, scene obstacles, and feedback. When using the fixed four-category contract, require response `sliceMode: "grid"` and exactly four slices before registering the local runtime sheet; both fewer and extra components fail closed. Treat `art-spec.png` as reference-only. A full-sheet `<img>`, CSS background, path-only mention, guessed equal-grid crop, or code-drawn replacement for core entities is not runtime asset use. If slicing produces `sliceWarning`, keep the complete transparent sheet as a valid editor artifact, but fail the playable game asset gate until real slice files or verified atlas coordinates exist; never invent coordinates or replace the icon-spritesheet route with ordinary image generation.

 ## Workflow

 1. Write executable source to `index.html`, `style.css`, and `game.js` in the current cwd. Use only relative paths returned by approved tools for media.
-2. Before using or deriving an existing registered asset, call `agc_list_registered_assets` and select its `localAssetId`. If the user points to an existing project file that is not listed, first call `agc_list_project_files`; only entries with `assetImportable=true` (recognized image, font, audio, video, document, or code files) may be passed to `agc_import_account_assets.localPaths`. Then re-read `agc_list_registered_assets`; never infer a source identity from a filename or fabricate a localAssetId.

If the user points to an existing project file that is not listed, first call `agc_list_project_files`; only entries with `assetImportable=true` (recognized image, font, audio, video, document, code, or engine asset such as a Cocos `.glb`/`.prefab`/`.anim`/`.mtl`/`.plist`/`.texture`) may be passed to `agc_import_account_assets.localPaths`. Then re-read `agc_list_registered_assets`; never infer a source identity from a filename or fabricate a localAssetId.
 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.
-6. When the user explicitly asks to remove an image background, call `agc_remove_background` with a registered image `sourceLocalAssetId` and an output name. The client requires the signed-in account, owns canvas/folder context and task identity, and returns only bounded queue state.
+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, and returns only bounded queue state.
 7. Preserve existing relative paths when a small edit is sufficient so client resource identities remain stable.
 8. Do not edit `.agent/manifest.json`, revision counters, version records, resource IDs, canvas identities, source provenance, generation ledgers, or browser receipts by hand.
 9. Do not create a version when no game file changed. The client compares content fingerprints and advances revision only after an actual source change.
