# Install "Codixel"

A pixel-art skill built on one idea: the agent writes code, it is not a painter. It asks for a reference image, then removes the background, pixelates, rigs with bones and animates it in code with a 2,000-line toolkit (core/pixel.js), showing every step on a sheet before making game files.

### Self-check after using the skill

- 复杂角色先要参考图，不凭空画；参考图要有使用授权 / Ask for a reference for complex subjects, and check you may use it
- 先给预览（GIF 和逐帧图），用户点头后才出 sprite sheet / Preview first (GIF and frame sheet); sprite sheet only after approval
- 关节位置用 P.ruler 读出来，绑骨后先看 ownerMap 再做动画 / Read joints off P.ruler; check ownerMap before animating
- 色数受控，抖动只出现在两种颜色交界处 / Colour count stays small; dither only where two colours meet
- 循环动画首尾帧接得上，所有帧尺寸一致 / Loops wrap cleanly and every frame has the same size
- 多张图拼成的角色，后续帧沿用第一帧的调色板 / Frames built from several images reuse the first frame's palette

## Verify
