Aseprite AI Artist
Your coding agent paints pixel art in the Aseprite window you already have open: draws, checks its work, animates and exports.
Listed from the author's README. GameSkill has not run this end to end yet. Agent support and install steps are as documented by the author.
Install
npx @pebbly/aseprite-ai-artist install-extensionThen quit and reopen Aseprite. The skill draws through this extension's tools.
/plugin marketplace add with-pebbly/aseprite-ai-artist
/plugin install aseprite@aseprite-ai-artistnpx skills add with-pebbly/aseprite-ai-artist --skill conceptStill needs the extension above and the project's MCP server connected to your agent.
Commands are copied from the project's README. Check the repository before running anything on your machine.

What you get
- Worked steps: Start from the brief; Write the art spec; Build the prompt; Offer the choice — once, in one message
Good fit
- After the brief for anything drawn from scratch, and whenever the user supplies reference art; skip for edits to existing art
Try this prompt
Design a forest shrine scene, and give me a concept prompt first.About this skill
Before drawing a new character, prop, scene or animation, write an art spec, turn it into a ready-to-paste prompt for an image-generation model, and offer the user a choice — generate a concept sheet or storyboard with it and send it back, or continue without one. When reference art arrives (from that prompt or from the user), read it into a PixelSpec and import it panel by panel, so the pixel work reproduces a decided design instead of improvising one. Use after the brief for anything drawn from scratch, and whenever the user supplies reference art; skip for edits to existing art.
From the concept SKILL.md in with-pebbly/aseprite-ai-artist.
What's inside
- Two modes
- Start from the brief
- Write the art spec
- Build the prompt
- Offer the choice — once, in one message
- Read the reference into a PixelSpec
- Import it
- Hand over to drawing
- What this must not do
Good to know
The agent paints with Aseprite's own tools through the Aseprite AI Artist extension, so the result stays an editable Aseprite file with layers and frames.
Requirements
- Aseprite 1.3+
- Node 22.6+
- The Aseprite AI Artist extension and MCP server
