Skill2 starsChanged 50 days agoApache-2.0View on GitHub

Entry point for 2D pixel assets — a character sprite with a locked palette and grid, idle/walk/attack/hurt animation strips, a tileset that shares the palette, and a style card so every later sprite matches. Use when the user says "pixel art", "sprite", "16-bit", "8-bit", "tileset", "retro 2D".

The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Distinctive:

    Grid first: Every asset is generated at the locked pixel size and never scaled by the model.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Pixel Art Sprite

Rules this entry enforces

  • Grid first. Every asset is generated at the locked pixel size and never scaled by the model. A 32-px character next to a 16-px tile is two games.
  • Palette is a list, not a mood. Hex values, counted. The style card carries it; every prompt pastes it.
  • Silhouette test. The character is recognisable as a black shape. Hats, weapons and hair do the work.
  • Consistent light direction. Top-left, stated once, obeyed in every sprite.
  • Animation from the idle. Each strip is generated with the idle frame as reference and a one-line delta per frame. Re-describing the character per frame produces five characters.
  • Era reference, not "retro". "SNES-era 16-bit with 4-tone ramps and dithering" is a spec; "retro" is not.
  • Seamless tiles verified. Edges are checked by tiling the output 3×3 before locking.

Example

Style card: 32 px · 24-colour palette (listed) · 1-px dark outline ·
  3-tone ramps, no dithering · top-left light · Celeste-era
Character: knight-cartographer · black braid reads as a single dark shape ·
        brass compass as a 2-px accent on the hip
Strips: idle 6 f (breath) · walk 8 f · attack 5 f (wind-up on f1–2) · hurt 3 f
Tileset: bone-brick ground · rib-wall · lantern (2-frame flicker) · fog overlay
