pixel-art-generation

pixel-art-generation is a skill for Claude Code from freema/pixelforge-mcp. It costs 55 tokens per session (1,094 once invoked), scanned A, original, MIT.

A workflow for creating and processing pixel art, the deliberately low-resolution style used for many game sprites and scenes.

In plain words
What is it for?
Generating game characters, items, icons, animations, backgrounds, and thumbnails, or cropping, removing backgrounds from, and splitting sprite sheets.
Why use it?
It tells the agent which PixelForge operation fits a sprite, animation, background, thumbnail, or existing PNG, including how to remove backgrounds.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pixel-art-generation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Pixel Art Generation with PixelForge

Use PixelForge MCP tools to generate and process pixel art game assets.

Tools Overview

Tool When to Use
forge_sprite Single sprite — character, item, icon, UI element
forge_animation Animation frames — walk cycle, idle, attack, effects
forge_background Full game background/scene — no processing applied
forge_thumbnail Game thumbnail/screenshot — uses reference sprites
process_sprite Post-process existing PNG — crop, bg removal, split

Background Removal — IMPORTANT

Always use background: "chromakey" for sprites and animations. This uses HSV-based green screen removal which is far more reliable than the old compositing equation approach.

  • chromakeyBEST — pure green #00FF00, HSV-based removal, clean edges, no artifacts
  • black / white — legacy compositing equation, can lose dark/light sprite pixels
  • Other colors — fallback to compositing equation

Quick Start

Single Sprite

forge_sprite
  description: "green slime enemy with horns and glowing eyes"
  outputPath: "public/assets/games/rpg/slime.png"
  style: "neon"
  background: "chromakey"

Animation Frames (Reference Chain — Default)

forge_animation
  description: "green slime enemy"
  action: "bouncing up and down"
  frames: 4
  frameDescriptions: ["idle resting on ground", "compressing flat", "stretching upward", "at peak of bounce"]
  outputPrefix: "public/assets/games/rpg/slime"
  names: ["idle", "compress", "stretch", "peak"]
  style: "neon"
  background: "chromakey"

Reference chain mode (default): Generates frame 0 first, then uses it as a reference image for all subsequent frames. This ensures consistent proportions, colors, and style across all frames. Each frame is a separate API call.

To use the legacy sprite-sheet mode instead: useReferenceChain: false

Background

forge_background
  description: "deep space with stars, subtle neon grid on horizon, nebula wisps cyan and purple"
  outputPath: "public/assets/games/invaders/bg.png"
  aspect: "3:4"
  style: "neon"
