Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.01789 |
| Opus 5 | $0.00028 | $0.00894 |
| Sonnet 5 | $0.00011 | $0.00358 |
| Haiku 4.5 | $0.00006 | $0.00179 |
Grade A, and why
spritecook-workflow-essentials scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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_balancebefore starting a batch or multi-asset workflow. - Use each asset's
sprite_urlas the canonical downloadable image URL. Usespritesheet_urlonly when it is present and specifically needed. - Save important
asset_idvalues in a local manifest whenever there is a writable workspace, unless the user explicitly wants a throwaway result. - When a workflow involves follow-up generations or animations for the same subject, identify and reuse the canonical
asset_idinstead of generating from scratch again. - If the agent loses track of generated asset IDs, recover them with
list_recent_assets(limit=...)before failing.
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
Authorizationheaders 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.
Async Operations
- Treat
generate_game_art,generate_tileset,remove_background,generate_character,generate_character_animations, andanimate_game_artas asynchronous operations. - Follow the returned
poll.toolwith its exactpoll.arguments. Do not invent a polling endpoint or search arbitrary response fields. - Use
operation_idas the generic identifier while retaining the returnedjob_idorrun_idfor the matching poll tool. - Pass
wait_secondsonly when the tool exposes it and an explicit bounded wait is useful; the normal default is immediate return. - On a terminal success, consume canonical
assets. If the response containswarning.code="asset_output_unavailable", execute its suppliedwarning.recoverytool call.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 6d ago First seen · 97 lines · 55 tokens per session scan A 428fec35719a
spritecook-workflow-essentials is a skill published in the GitHub repository SpriteCook/skills (30 stars, last pushed 19d ago), licensed MIT. It adds 55 tokens to every session and 1,789 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
