SpriteCook Agent Skills

Agent skills for SpriteCook - AI-powered game asset generation. These skills teach AI coding agents how to generate pixel art and detailed/HD game art, plus animate existing assets with SpriteCook's MCP tools.

Skills follow the open Agent Skills standard and work across all compatible editors.

Available Skills

spritecook-workflow-essentials

Shared workflow rules for SpriteCook:

• Check credits before larger runs
• Follow asynchronous generation polling contracts
• Use canonical sprite_url and optional spritesheet_url outputs
• Save reusable asset_id values in a local manifest
• Upload local image files through SpriteCook MCP asset-upload tools
• Import small data URLs with import_asset
• Rename useful assets with update_asset_label
• Use smart_crop_mode="tightest" by default
• Use Nano Banana 2.1 (gemini-nano-banana-2.1) as the recommended default for new pixel-art sprites and characters
• Use Pixel Engine Image (pixel-engine-image-v1) for single sprites at an exact size from 16 to 128 px, background already removed. It is text only, so it takes no reference or edit images
• Check plugin versions when the user asks about updates or compatibility

spritecook-generate-sprites

Still-image generation guidance:

• Generate production-ready pixel art or detailed/HD assets
• Choose the right mode, model, and crop settings
• Keep style consistency with reference_asset_id
• Use edit_asset_id only when modifying an existing SpriteCook asset

spritecook-polish-sprites

Post-generation outline and transparency cleanup:

• Understand why background removal can leave broken outlines or missing edge pixels
• Inspect saved alpha-cutoff settings and download the preserved source once
• Compare thresholds locally with the bundled Python/Pillow helper
• Save the chosen cutoff through MCP without rerunning a provider or spending credits
• Polish sheets before slicing and inspect animation frames for edge flicker

spritecook-build-ui-kits

Concept-first UI system guidance:

• Build complete menus, HUDs, inventories, dialogs, settings screens, and overlays
• Reuse an existing SpriteCook concept asset ID or generate/select a coherent concept
• Generate transparent component sheets, extract named controls and states, and finalize 9-slice metadata
• Keep normal mode="ui" generation focused on individual UI elements

spritecook-animate-assets

Animation workflow guidance:

• Upload local image files, then animate by the returned asset_id
• Use remove_background for transparent cutouts when needed
• Use edge_margin=6 by default for safer framing
• Write grounded, character-specific motion prompts
• Use auto_enhance_prompt=true when simple prompts like Idle or Attack are enough

spritecook-use-assets-in-godot

Godot export workflow guidance:

• Export completed character animation runs into Godot 4.x projects
• Materialize SpriteCook MCP text_files and asset_downloads manifests
• Set up SpriteFrames importer files and ready-to-test player scenes
• Use AnimatedSprite2D for platformer exports and AnimatedSprite3D for top-down/isometric exports

Installation

Quick install (all compatible editors)
