# layer-pixel-art

A skill for making pixel art with Layer: sprites, tiles, walk cycles, and packing frames into a sheet. Useful when output comes back blurry or off-grid.

## What it does

Pixel art is the generation task that most often returns subtly wrong: a picture of pixel art, soft-edged and anti-aliased at some arbitrary grid. This skill fights that with explicit numbers. Name the grid and the palette every time — "32x32 sprite", "limited 16-colour palette, muted earth tones". Give the model no grid and you get something pixel-ish at no particular resolution, and no cleanup will fix it afterwards.

The defects are predictable, so list them as exclusions: no anti-aliasing, no blur, no gradients, hard-edged pixels only. Where the model takes `negative_prompt`, put them there instead. State the background too — transparent, or a flat single colour — because a generated backdrop has to be cut out, and pixel art does not survive a sloppy cut.

Never ask one generation for a whole sheet. The model returns a grid of loosely related drawings and the character shifts between cells, which is the one thing a sheet must not do. Generate and approve a single frame first, then each remaining frame on its own with the approved one attached as `reference_image`, describing only the pose change. Every frame references frame one, not the frame before it; chain them and the character drifts by frame four. `pack_sprite_sheet` assembles the frames into uniform cells, and `split_sprite_sheet` cuts an existing sheet into its cells.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-pixel-art -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/layer-pixel-art/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/layer-pixel-art/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-pixel-art -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/layer-pixel-art/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-pixel-art -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/layer-pixel-art/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/layer-pixel-art/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/layerai/skills/tree/HEAD/skills/layer-pixel-art/SKILL.md

## When to use it
- generate a character sprite on a 32x32 grid with no blur
- pack separate animation frames into a sheet with even cells
- split someone else's sheet into frames to edit just one
- build a walk cycle where the character stays the same across frames
- get a tile that repeats without a visible seam

## Example prompts
- Make a 32x32 pixel art sprite of a knight, side view, 16-colour palette, hard-edged pixels, no anti-aliasing, transparent background
- Pack these four frames into a sheet with `pack_sprite_sheet`
- Split `knight_sheet.png` into individual frames, I only want to fix one

# Layer Pixel Art

## Overview

Pixel art is the generation task most likely to come back subtly wrong: a picture _of_ pixel art,
soft-edged and anti-aliased at an arbitrary grid, rather than pixel art. Getting it right is mostly
about excluding the defaults.

Layer ships two deterministic sprite-sheet utilities alongside generation. `pack_sprite_sheet`
assembles separate frame images into one uniform-cell sheet on a transparent background, and
`split_sprite_sheet` cuts a sheet into its cells in reading order. These are named directly rather
than discovered because they are first-party tools rather than models, with no competing
alternative in the catalogue.

Generation mechanics are in the `layer` skill. If a sibling skill named here is missing from your
available skills, ask the user to install it (`npx skills add layerai/skills --skill <name>`);
unattended, proceed from tool schemas and flag the gap.

## Name the grid and the palette

Both, every time, as numbers.

- **Grid**: "32x32 sprite", "16x16 tile". A model given no grid produces something pixel-ish at no
  particular resolution, which cannot be cleaned up afterwards.
- **Palette**: a count and a family. "Limited 16-colour palette, muted earth tones" constrains the
  output in a way "retro colours" does not.
- **Era**, when the user has one in mind: 8-bit NES-era flat colour, 16-bit SNES-era with shading
  ramps, or modern high-resolution pixel art. These look nothing alike.

## Exclude the defaults, in the prompt

The defects are predictable, so name them as exclusions: no anti-aliasing, no blur, no gradients, no
soft shadows, hard-edged pixels only, one pixel per cell. Where the model declares `negative_prompt`,
put them there instead. Also state the background: "isolated on transparent background" or "flat
