SpriteCook Workflow Essentials

Use this alongside the SpriteCook image or animation skill whenever SpriteCook MCP tools are available.

Requires: SpriteCook MCP server connected to your editor. Set up with

npx spritecook-mcp setup

or see spritecook.ai.

Preflight Checklist

Check credits first with
```
get_credit_balance
```
before starting a batch or multi-asset workflow.
Prefer presigned download URLs over authenticated asset endpoints.
Save important
```
asset_id
```
values in a local manifest whenever there is a writable workspace, unless the user explicitly wants a throwaway result.

Credential Safety

Never ask the user to paste a SpriteCook API key into chat, prompts, code blocks, shell commands, or generated files.
Never print, persist, echo, or inline API keys or
```
Authorization
```
headers in agent output.
Prefer SpriteCook MCP tools, presigned URLs, or a preconfigured local connector/helper that handles authentication outside the prompt.
If a raw API call is required and no authenticated helper exists, stop and ask the user to configure one.

Defaults

Prefer
```
smart_crop_mode="tightest"
```
for the best default results. Use
```
"power_of_2"
```
only when the user explicitly asks for it.

Model guidance:

```
gemini-2.5-flash-image
```
: cheapest
```
gemini-3.1-flash-image-preview
```
: recommended default
```
gemini-3-pro-image-preview
```
: most expensive

Asset Manifest

Treat
```
asset_id
```
as the primary stable identifier.
Store a 12-character SHA-256 prefix (
```
sha12
```
) for saved local files.
Use a minimal manifest entry shape:
- ```
asset_id
```
- ```
sha12
```
- optional
```
label
```
Prefer a simple machine-readable file such as
```
spritecook-assets.json
```
unless the project already has an asset manifest.
Before generating a new reference asset or asking the user for an asset id, check the local manifest first.
Before reusing a local file, compute its
```
sha12
```
and match it against the manifest to recover the correct
```
asset_id
```
.

Downloading Assets

Prefer
```
_presigned_pixel_url
```
when saving the pixel PNG.
Prefer
```
_presigned_url
```
when saving the raw/original image.
Avoid direct authenticated download endpoints in skill-driven workflows unless a helper handles auth out of band.
