Pixelbolt plugin
Pixelbolt lets an agent draw and edit pixel art from a JSON recipe: sprites, effects and animations as PNG, GIF and atlases.

Minimal access
Why this level
- The tool works locally and writes files only into the chosen export folder.
- `npx -y` runs an npm package, and with `latest` the version floats.
Install
- Works in
In your terminal, with SkillFoxx CLI
npx skillfoxx add plugins/pixelboltDetects the agents on your machine, shows the access level and pins the version.

What it does
Pixelbolt turns an editable JSON recipe into sprites, tiles, icons, effects and short animations and exports them as PNG sheets, texture atlases, animated PNG, GIFs and frames for a video editor. An agent works with it through a local MCP server or the command line, and you can open the same recipe in a browser studio, play it and edit it. Fire, smoke, steam, explosions, magic, water, honey, slime and sand come from a real fluid simulation that runs on your CPU in under a second and bakes into palette pixels with seamless loops. The agent reads every pixel back and fixes one pixel or frame without redrawing the rest, and one recipe always gives the same image. There are no dependencies, Node.js 20 or newer is needed, and no API key or network.
Who it is for. Game developers, jam teams and web or video makers who want an agent to draw and revise small 2D assets stored as text.
Good fit when
- A sprite sheet with an atlas is needed for a game engine such as Godot or Unreal Paper2D.
- An agent must fix one eye of a character and leave the rest of the drawing alone.
- A campfire or explosion is needed as a looping GIF animation or frames for editing.
- The same image must come from a recipe on every run.
Not a fit when
- A painted or photographic image is needed: the tool makes pixel art.
- A large animation is needed: an animation frame is at most 256 by 256 pixels and a project at most 256 frames.
- An illustration without an editable recipe is wanted: the result is stored as a text specification.
Example request
Draw an eight-frame campfire sprite sheet with a seamless loop, export a PNG and an atlas, then fix one coal pixel without redrawing the rest.Limitations
An animation frame is at most 256 by 256 pixels, a project at most 256 frames and 4,194,304 pixels in all, and a single still can be up to 4096 pixels. Wave effects are loops only, with no reflection or collision simulation. Installing through `npx skills` needs Node.js 22.20 or newer, and the utility reports installs to the skills.sh leaderboard unless `DISABLE_TELEMETRY=1` is set. The project was called PixelForge until version 0.8.0, and the `pixelforge` command remains an alias. The last commit was made on 11 November 2026.
How to disable. For Claude Code remove the plugin with `/plugin uninstall pixelbolt` or the `~/.claude/skills/pixelbolt-pixel-art/` folder. In other agents remove the `pixelbolt` entry from the MCP configuration.
FAQ
How do I install Pixelbolt in Claude Code?
With `npx -y pixelbolt@latest skill install`, which writes the skill into `~/.claude/skills/pixelbolt-pixel-art/`. The plugin with the MCP server is installed with `claude plugin install pixelbolt --marketplace skulitom/Pixelbolt`.
How do I connect the MCP server to another agent?
Add a `pixelbolt` server to `mcpServers` configuration with the `npx` command and arguments `-y pixelbolt@latest mcp --out` and an absolute export folder path.
Which export formats exist?
Transparent PNG sheets, texture atlases, animated PNG, GIF and numbered frames for a video editor.
Are API keys or network needed?
No. There are no dependencies, image model or network service, and only Node.js 20 or newer is required.
Does it work in a browser?
Yes, the studio and playground open in a browser, and a recipe can be played, edited and shared as a link.
