 # Genarrative External Editor API
 
-Discover the live integration through `GET https://www.genarrative.world/api/external/v1/agent-integration.json`. Treat `GET https://www.genarrative.world/api/external/v1/openapi.json` as the field-level source of truth. In this repository, the same contract is `docs/openapi/genarrative-external-v1.openapi.json`.
+Use Genarrative to manage canvas projects and asset-library records, generate images, character animations, videos, and audio, and edit images. Discover the hosted integration at `https://www.genarrative.world/api/external/v1/agent-integration.json`.
 
-Prefer the hosted Streamable HTTP MCP at `https://www.genarrative.world/api/external/v1/mcp` when the Agent supports remote MCP with a custom Bearer token. It exposes the External v1 operations as tools and the Skill documentation as resources; it does not require a local MCP server. Use this complete Skill package when remote MCP is unavailable or local-file upload needs client-side orchestration.
+Connect to `https://www.genarrative.world/api/external/v1/mcp` using Streamable HTTP and a Bearer API Key. Read tool descriptions and input schemas from `tools/list`; read the documents below through `resources/read` when needed. The hosted service needs no local MCP server. For direct REST, use the live `/api/external/v1/openapi.json` contract (in this repository: `docs/openapi/genarrative-external-v1.openapi.json`).
 
-Prefer `scripts/genarrative_external_api.py` for runnable REST calls. It uses only Python stdlib, reads the local private API Key file, keeps the production base URL fixed, uploads local references, and wraps asynchronous submission, polling, and result retrieval.
+## Working with the Service
 
-## Workflow
-
-1. Discover the integration manifest. Choose hosted MCP when supported; otherwise use the helper or direct REST.
-2. Before the first generation in a new conversation, obtain a canvas name unless an existing `projectId` and `assetFolderId` were supplied. Create or reuse a project and a same-name asset-library folder. Retain `canvasName`, `projectId`, `assetFolderId`, and the current art spec.
-3. Normalize art requests into a reusable spec. Ask only for missing values that block the selected operation. Reuse the spec until the user changes its style, subject family, palette, format, or constraints.
-4. Infer the operation from the user's intent. Do not ask the user to select an API unless two operations would produce materially different artifacts.
-5. If a reference exists only as a local file, upload and confirm it first. Pass the stable returned `objectKey` to operations that accept object references; never substitute a temporary signed URL. For an icon-spritesheet primary spec, additionally create a project resource or asset record with `assetKind="icon-spec"`, then pass the returned resource or asset ID as `referenceId`.
-6. For generation endpoints that support the fields, include `projectId`, `assetFolderId`, an asset label, and `canvasCompletion` so the result enters both the canvas and its same-name library folder.
-7. Treat every generation POST as asynchronous. Send one stable `Idempotency-Key` per logical request, retain the returned `operationId`, and poll the returned `statusUrl` or `GET /api/external/v1/generations/{operationId}` according to `pollAfterMs`.
-8. Consume `result` only after `status=completed`. On `failed`, surface the safe error. On a client timeout or lost response, retain the operation/key; do not create a replacement request.
-9. Reload the normal project or asset-library read endpoint when the caller needs complete authoritative state. Generation results are intentionally compact.
-10. Stay within `/api/external/v1`. Never call internal workers, queues, admin/profile APIs, or SpacetimeDB endpoints unless the user explicitly changes scope.
-
-## Essential Invariants
-
-- Authenticate MCP and business API calls with `Authorization: Bearer <tnr_sk_...>`. Never ask the user to paste a key into chat or place one in repository files.
-- All nine generation POST routes require `Idempotency-Key` and return HTTP `202`; `202` is durable acceptance, not a media result.
-- Retry an uncertain submission only with the exact same body and the same idempotency key. A polling timeout is not permission to generate again.
-- 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 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.
+- Select tools by the requested outcome. Use `find_canvas_projects` and `find_assets` to locate existing context; create projects or folders only when the task needs them. A folder need not have the same name as the project.
+- For generation, specify project, library, and `canvasCompletion` fields only as supported by the selected tool and needed for the requested destination. Do not duplicate records already created by generation.
+- Upload local references using `prepare_asset_upload`: request a ticket, transfer the file from the client, then confirm the object. Confirmation does not create a canvas layer or a project/library record. Use the reference type accepted by the target tool; some operations require a registered resource or asset ID rather than an object key.
+- Generation is paid and asynchronous. Keep one stable `idempotencyKey` per logical generation and retain the returned `operationId`. Call `check_generation` according to `pollAfterMs`; consume `result` only after `completed`, and report the safe error on `failed`. A polling timeout does not justify another generation.
+- Read actual artifacts and warnings before claiming the requested deliverable is complete. Use project/library reads for complete persisted records, and `find_assets` with `action=get_download_url` for temporary media access.
+- Keep API Keys and temporary upload/download credentials out of chat, repository files, and logs. Business calls operate within the API Key's owner and scopes.

+## Direct REST and Local Helpers
 
-## Hosted Integration Discovery
+When remote MCP is unavailable or local-file orchestration needs a helper, the complete package is available at `GET /api/external/v1/skill.zip`; the raw entry is at `GET /api/external/v1/skill/SKILL.md`. Verify the archive SHA-256 against the integration manifest before installing. The archive includes this entry, four references, `scripts/genarrative_external_api.py`, and `agents/openai.yaml`. Discovery and documentation downloads are public; MCP and business calls require authentication.
 
-- Manifest: `GET /api/external/v1/agent-integration.json`.
-- Hosted MCP: `POST /api/external/v1/mcp`, Streamable HTTP, same Bearer API Key.
-- OpenAPI: `GET /api/external/v1/openapi.json`.
-- Raw Skill entry: `GET /api/external/v1/skill/SKILL.md`.
-- Complete Skill archive: `GET /api/external/v1/skill.zip`.

-The archive contains this main file, four one-level references, the Python helper, and `agents/openai.yaml`. Verify its SHA-256 against `agent-integration.json` before installing. Discovery, OpenAPI, and Skill downloads are public; MCP and business operations require authentication.
-
-## Python Helper
-
-Store the API Key outside the repository at `~/.config/genarrative/external-editor-api.json`:
-
-```json
-{
-  "apiKey": "tnr_sk_..."
-}
-```
-
-Set restrictive permissions where possible, then smoke-test without printing the key:
+The Python stdlib helper reads the private API Key file described in [authentication and safety](references/authentication-and-safety.md) and uses the production base URL. For a read-only smoke test:
 
 ```bash
-chmod 600 ~/.config/genarrative/external-editor-api.json
 python3 .codex/skills/genarrative-external-editor-api/scripts/genarrative_external_api.py list-projects
 ```
 
-For a canvas-backed generation:
+Its `prepare_canvas_session` convenience method creates or reuses a project and a same-name folder. Use it only when that organization matches the task; it is not a prerequisite for MCP or REST calls. Convenience generation methods wait locally while the server uses short asynchronous submit/status requests. Use `submit_generation`, `get_generation`, and `wait_for_generation` for caller-controlled orchestration; see [requests and outputs](references/requests-and-outputs.md).
 
-```python
-from genarrative_external_api import GenarrativeExternalClient
-
-client = GenarrativeExternalClient()
-session = client.prepare_canvas_session("新画板")
-client.generate_image(
-    "生成一张 16:9 幻想森林游戏背景",
-    canvasSession=session,
-    assetLabel="森林背景",
-    aspectRatio="16:9",
-    imageSize="1K",
-    artSpec={
-        "assetType": "background",
-        "subject": "幻想森林主视觉",
-        "style": "手绘游戏概念图",
-        "palette": "翡翠绿与金色光斑",
-        "composition": "横版，中心留出角色站位",
-        "format": "16:9, 1K",
-        "constraints": "无文字、无 UI 按钮",
-        "references": [],
-    },
-)
-```
-
-For background removal, pass a stable owner-scoped object key, project resource ID, or asset ID; the helper keeps the same asynchronous submission and polling contract:
-
-```python
-session = client.prepare_canvas_session("去背景画布")
-client.remove_background(
-    "editor-upload/object.png",
-    source_width=720,
-    source_height=1280,
-    canvasSession=session,
-    assetLabel="去背景结果",
-)
-```
-
-Background removal preserves the source pixel size. For normal canvas placement with `canvasSession`, pass the real `source_width` and `source_height`, or provide both `canvasWidth` and `canvasHeight`; the helper rejects missing dimensions instead of guessing a square placeholder. `assetKind` may only describe a static image and must match the authoritative source record. Prefer a project resource ID or asset ID when the same object key has multiple semantic registrations; for a raw object key outside in-place replacement, pass `sourceResourceId` to disambiguate. Passing `targetLayerId` selects in-place replacement: the helper retains the session's project/library context but does not inject `canvasCompletion`, and it rejects an explicit `canvasCompletion` combined with `targetLayerId`. The target layer must point to the same authoritative object as the source, and the server durably binds a raw object key to that target resource for Worker revalidation.
-
-Helper convenience methods wait locally, but the server still uses short asynchronous submit/status requests. For durable caller-controlled orchestration, call `submit_generation`, persist its `operationId` and idempotency key, then call `get_generation` or `wait_for_generation`.
-
-For character animation, pass the canvas session and asset label to `animate_character`. The helper submits asynchronously and returns the completed compact result containing the authoritative formal `resource` and `asset`; do not synthesize a library asset from the first frame.
-
-## Guardrails
-
-- Do not change the fixed production base URL in generated examples.
-- Do not move the API Key into environment variables, source files, generated projects, logs, docs, screenshots, or shell snippets containing literal secrets.
-- Do not treat a Data URL, Blob URL, expiring signed URL, worker lease, or provider diagnostic as a durable result.
-- Do not reconstruct authoritative canvas, resource, or library snapshots from a compact generation response.
-- Do not replace icon-spritesheet generation with ordinary image generation when the deliverable requires a reusable transparent atlas.

 ## Canvas and Library Field Rules
 
-- Pass `projectId` and `canvasCompletion` to write generated output into the canvas.
-- Pass `assetFolderId` plus `assetLabel` for image, edit, icon spritesheet, video, sound effect, and BGM operations when supported.
+- Pass `projectId` and `canvasCompletion` when the task calls for generated output in a canvas.
+- Pass `assetFolderId` plus the relevant label field when the task calls for a library record. Neither destination requires the other, and their names need not match.
 - UI extraction uses `assetFolderId` and `spritesheetLabel`.
-- Character animation accepts `assetFolderId` and `assetLabel`. Its completed compact result directly returns the final `assetKind="character-animation"` resource and asset with `imageSequenceFrames` and `imageSequenceDurationMs`; never create a duplicate first-frame resource or asset.
+- Character animation accepts `assetFolderId` and `assetLabel` and persists the generated sequence. Consume returned artifacts and persisted identities; never create a duplicate first-frame resource or asset.
 - Background removal derives the final static-image `assetKind` from the authoritative source record. A conflicting request kind or any video, audio, animation, or image-sequence kind returns `400` before queueing. Without `canvasCompletion`, `targetLayerId` must point to the same authoritative object as `sourceImageSrc` (prefer `assetObjectId`, otherwise canonical bucket/object key).
 - If a caller must manually create a `character-animation` resource or asset, put the authoritative frames and total sequence duration in `imageSequenceFrames` and `imageSequenceDurationMs`. Keep `generationInputs` replayable: it must not contain legacy runtime fields such as `characterAnimation`, `frames`, `previewVideoPath`, `frameCount`, `fps`, or `durationSeconds`.
 - Reload project/library state after completion when full current state is required.

The direct operation tools use `body`, `pathParameters`, and `queryParameters` wrappers as shown by their live schemas.
 
 Do not present an API menu unless the request is genuinely ambiguous. Ask a follow-up when two routes create different artifacts, for example “处理这张图” could mean edit, extract marked UI assets, or use it as a reference for a new generation.
 
 ## Route-Specific Decisions
 
-- Use image edit when the requested output replaces or modifies a source image. With `projectId`, pass `targetLayerId` to replace an existing layer when no explicit `canvasCompletion` is supplied.
+- Use `modify_image` `edit` when the requested output modifies a registered source image. Use `variation` when reference images should guide a new `quick-edit` image; it is image generation with fixed `kind="quick-edit"`. Use `remove_background` for a static source image. With `projectId`, `targetLayerId` may replace a matching existing layer when no explicit `canvasCompletion` is supplied.
 - Use icon spritesheet generation for a transparent reusable atlas when a stable visual-spec reference and concrete `iconDescriptions` exist. Do not use ordinary image generation just because it can draw several objects.
 - Use UI extraction only for an existing UI design image with red-box annotations. It is not UI generation.
-- Use a project layer ID as character animation `sourceLayerId` when one exists. For a local-only source, derive a stable synthetic ID from the filename.
+- Character animation requires a real `sourceLayerId`, source image, and dimensions from an existing resource. A local-only file must first be uploaded and registered where needed; do not invent a layer ID.
 - For video with image/video/audio references, use a Seedance 2.0-family model; default to `seedance2.0-fast`, `mode: "std"`, and explicit `sound`.
-- Use `signedUrl` only for preview/download. Feed stable `objectKey` or registered resource/asset identifiers into generation.
+- `prepare_asset_upload` obtains a ticket and confirms an uploaded object; it does not transfer the file or register a project resource, asset record, or canvas layer. Use `edit_canvas` `register_resource` or `organize_asset_library` `create_asset` only when the task needs those records.
+- Use temporary signed URLs only for preview/download. Feed stable `objectKey` or registered resource/asset identifiers into generation as each operation permits.
 
-## AI Game Creator Canonical Visual DAG
+## Example: Reusable Icon Assets
 
-Keep the existing autonomous-build task graph. Do not add a parallel task system or collapse these artifacts into one ordinary generation request:
+When the task needs a visual spec and a reusable icon atlas:
 
-1. `art-director` generates `assets/art-spec.png` with image generation, `kind: "spec"`, then registers it as `assetKind: "icon-spec"`. This image is the authoritative visual spec; `generationInputs.artSpec` is supporting structured context.
-2. `design-foundation` generates `assets/ui-prototype.png` with `kind: "ui-design"`, using the registered art-spec resource ID in `referenceImageSrcs`.
-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`.
+1. Reuse an existing registered `icon-spec`, or generate the requested spec using `generate_image` with `kind=spec` and register it as `assetKind=icon-spec` if necessary.
+2. Call `generate_icon_spritesheet` with that registered ID as `referenceId`, concrete `iconDescriptions`, and explicit `sliceMode`. Choose `grid` only for requested equal cells or fixed slots and provide those `gridX`/`gridY` values; otherwise use `connected-components`, optionally with `sliceCount`.
+3. Query `check_generation` and inspect the full sheet and actual slices. Preserve warnings; a usable full sheet does not imply that individual slices exist. Use returned slice identities and dimensions rather than guessing crop coordinates.
 
-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 the requirement fixes grid slots, require the response `sliceMode` to match the declared `grid` request and exactly `gridX × gridY` slices before registering the local runtime sheet; a connected-components request is instead judged by its own `sliceCount` or by the requirement, and 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.
-
-Never use `assets/ui-prototype.png` as the spritesheet visual-spec reference. UI extraction is outside this canonical DAG.
+An ordinary UI mockup or uploaded image is not automatically an `icon-spec`. For extracting marked components from a UI design, use `extract_ui_assets`, which includes generation and does not promise pixel-exact cropping.
 
 ## Scope Boundary
 
-Stay within `/api/external/v1`. Do not invent worker, queue, runtime task-list, admin, profile, or SpacetimeDB calls. The only external generation query is `GET /api/external/v1/generations/{operationId}`.

+## MCP Argument Shapes
+
+Pass these objects as the `arguments` of the named tool in `tools/call`. They are not REST request envelopes.
+
+Single-function tools take business fields directly. For example, `generate_image`:
+
+```json
+{
+  "prompt": "一张横版幻想森林背景，无文字",
+  "aspectRatio": "16:9",
+  "imageSize": "1K",
+  "idempotencyKey": "forest-image-001"
+}
+```
+
+Multi-function tools take `action` and `input`. A generation key stays outside `input`. For example, `generate_audio`:
+
+```json
+{
+  "action": "sound_effect",
+  "input": {"prompt": "轻柔的游戏菜单确认音", "duration": 1},
+  "idempotencyKey": "menu-sound-001"
+}
+```
+
+Keys above identify distinct example requests; create and persist your own key for each new logical generation. An action with no business fields still requires `input: {}`, such as `find_canvas_projects` with `action=list`. Use only fields belonging to the selected action; do not combine branches. REST examples below use the business body directly and put the key in the HTTP header instead.
+
+MCP returns business data in `structuredContent`, without the REST `data` envelope. Check `isError` before using it; an HTTP-successful MCP exchange can still carry a tool error. Generation acceptance contains an `operationId`, not the final media.

@@ -102,15 +133,24 @@ A minimal `canvasCompletion` is:
 
 Background removal preserves the source image dimensions. For normal canvas placement, the Python helper therefore requires the real `source_width` and `source_height` whenever `canvasSession` is used without an explicit `canvasWidth` plus `canvasHeight`; it never substitutes a square default. Passing `targetLayerId` instead selects in-place replacement, so the helper keeps the session's project/library fields without injecting `canvasCompletion` and rejects callers that explicitly combine both placement modes. The request `assetKind` is optional, static-image only, and must equal the authoritative source type when one exists. An in-place target must resolve to the same authoritative source object; a raw object key is bound to that target resource instead of relying on project-list order.
 
-Character animation accepts `assetFolderId` and `assetLabel` and persists the final transparent sequence directly. Its completed compact result includes the authoritative `assetKind="character-animation"` resource and asset with `imageSequenceFrames` and `imageSequenceDurationMs`. Use those records directly and never synthesize a duplicate asset from the first frame.
+Character animation accepts `assetFolderId` and `assetLabel` and persists the generated sequence. Consume the returned animation artifacts and persisted identities; do not synthesize a duplicate animation asset from the first frame. Use complete project/library records when complete persisted state is needed.
 
 For the lower-level asset/resource creation endpoints, `generationInputs` is replayable request context rather than a media-runtime container. When `assetKind` is `character-animation`, the server rejects legacy runtime keys including `characterAnimation`, `frames`, `previewVideoPath`, `frameCount`, `fps`, and `durationSeconds`; send the formal sequence through `imageSequenceFrames` and `imageSequenceDurationMs`. Internal processing audit keys such as `screenColorHex`, `mattingProvider`, and `mattingModel` are removed before persistence.
 
+## Saving Existing Canvas Layout
+
+1. Call `edit_canvas` with `action=get` and `input.projectId` to read the latest project and canvas revision.
+2. Build the intended complete `viewport` and `layers`, preserving unrelated layers. `save_layout` replaces the layout; it is not a one-layer patch.
+3. Call `edit_canvas` with `action=save_layout` and `input` containing `projectId`, the read `expectedRevision`, and the complete `viewport` and `layers`.
+4. On a revision conflict, reread and reconcile with the current layout before retrying. Do not blindly resend stale layers with a refreshed revision.
+
+`edit_canvas/register_resource` registers existing media but does not create a canvas layer. `organize_asset_library/create_asset` creates metadata but does not upload or generate media. For generated media placement, prefer the generation tool's supported `canvasCompletion`; inspect returned identities before registering anything again.

 ## Art Spec and Image Request
 
 Generic External v1 image generation does not expose the main-site structured game-scene contract. `kind: "scene"` and `assetKind: "scene"` are both invalid and return HTTP `400` before any generation job is queued. Do not replace the structured scene fields and server-owned prompt assembly with a generic image prompt.
