Do I need other skills to use this?

This skill is designed to work in tandem with the gemini-image-gen skill to handle the actual image generation via Google's Gemini models.

How does this skill maintain visual consistency?

It uses the anchor image as a mandatory reference in Phase 2 generation calls and enforces specific grid prompts to ensure the AI maintains proportions across all cells.

What is the Anchor-First Pipeline?

It is a specialized workflow where a single 'hero' sprite is generated and approved first to act as the permanent style and detail reference for all subsequent animation frames.

Does it support isometric game views?

Yes, it is optimized for isometric projections by generating NE/SW views and automatically flipping them to create NW/SE counterparts.

Can it handle different animation states?

Absolutely. The master sheet layout uses rows to define different states like 'idle', 'running', or 'destroyed', which are then sliced into individual labeled files.

Generates consistent, game-ready sprite sheets and animations using a structured Anchor-First AI pipeline.

The Sprite Sheet Generator skill solves the problem of style drift in AI-generated assets by implementing a rigorous 'Anchor-First' pipeline. By establishing a single 'hero' sprite as a visual reference, it ensures that all subsequent animation states and directional views maintain identical proportions and details. This skill streamlines the entire game asset workflow—from generating multi-state master sheets with Gemini to automatically slicing them into individual files and creating mirrored frames for isometric or side-scrolling projections.
