Sprite Sheet Generation

Role

High-level asset workflow for producing a single character or object as an animation sprite sheet. This skill owns the grid spec, prompting, slicing, and QA. It delegates image generation to codex-imagegen-backend and background removal to greenscreen. For standalone single-frame sprites, use sprite-gen instead.

Before generating, read the codex-imagegen-backend and greenscreen skills and use their bundled scripts as documented. Python 3 and Pillow are required for alpha validation, slicing, and resizing.

Grid Semantics

These rules are fixed; state them explicitly in every prompt:

• Rows = actions. One action per row (idle, walk, run, attack, jump, hurt, death, ...), ordered top to bottom.
• Columns = animation frames. Time order runs left to right; frame 1 is the start pose. Every row has the same number of columns.
• All cells are uniform squares with no gutters, margins, labels, or grid lines. The character is centered in each cell with feet on a consistent baseline and nothing crossing cell boundaries.

Sheet Spec

Collect one spec per sheet before generating:
