Is the Sprite Gen skill free?

Yes. The skill itself is free from aldegad/sprite-gen. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Sprite Gen SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Sprite Gen?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Sprite Gen with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · bc1271b

Ran the deterministic pipeline live: an irregular magenta-chroma raw strip went through extract + compose and it separated four poses by connected components, re-centered every frame to the same centroid (0.0px spread vs 16px for a naive fixed-grid slice), and emitted a valid 1024x1024 RGBA atlas plus a frame_layout manifest with zero chroma leakage. The single AI generation step needs codex/grok OAuth binaries that weren't available, so image-gen quality is unmeasured, but the distinctive deterministic chroma-to-component-to-centered-cell-to-atlas core clearly beat the baseline. Install runs verbatim from a bare HOME and every spot-checked script and doc exists.

What Sprite Gen does

Builds 2D game sprite sheets through a deterministic component-row pipeline: chroma-key alpha removal, connected-component frame extraction, centered cells, atlas composition and a runtime frame_layout manifest, plus a local webview to curate image candidates side by side. Triggers when you want to generate sprite/animation atlases for a game character or need to visually compare and pick from a set of generated images.

How to install Sprite Gen

git clone --depth 1 https://github.com/aldegad/sprite-gen.git
mkdir -p ~/.claude/skills
cd sprite-gen && cp -r . ~/.claude/skills/sprite-gen

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Sprite Gen

/sprite-gen Turn AI row strips into clean 2D sprite atlases with a runtime manifest

It also activates on plain-language prompts like these:

Turn this AI-generated row strip into a clean sprite atlas for my game.
Extract and center these character poses into a runtime frame manifest.
Show me candidate sprite images side by side so I can pick the best one.
