Sprite Gen
aldegad/sprite-gen
Generates images and game sprites through GPT or Grok with guided provider choices, separate saved defaults, automatic cleanup and optional curation.
Turn a vague pixel-art request into a written brief — size, palette, view, light, outline style — and confirm it with the user before any pixel is drawn.

What it does
Brief is an agent skill from with-pebbly/aseprite-ai-artist. Turn a vague pixel-art request into a written brief — size, palette, view, light, outline style — and confirm it with the user before any pixel is drawn. Use when the request is open-ended ("make me a knight") rather than a specific edit.
Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Sprites and pixel art. It works with Model Context Protocol. The repository describes itself as: Your coding agent paints pixel art in the Aseprite window you already have open. MCP server + skills for Claude Code, omp, Codex, Gemini CLI and Cursor — draws, looks at its…. The licence is MIT.
When your agent uses it
- The request is open-ended (make me a knight) rather than a specific edit
- Tasks that involve Sprites and pixel art
Example prompts
- “make me a knight”
- “/brief”

What it can do on your machine
Read from SKILL.md and the folder at commit f51fe69. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Brief loads about 833 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 450 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Plan a sprite before drawing it
Plan a sprite before drawing it
A request like "draw me a knight sprite" contains none of the decisions that determine whether the result is usable. Guessing them and drawing anyway wastes the user's time and yours. Five questions, one answer, then draw.
What you need to know
| Decision | Why it cannot be deferred | Reasonable default |
|---|---|---|
| Canvas size | Determines how much can be shown at all | 32×32 for a character |
| Palette | Choosing it later means repainting | PICO-8 (16 colours) |
| View | Side-on, top-down and 3⁄4 are different drawings | 3⁄4 |
| Light direction | Must be fixed before any shading | Upper-left |
| Outline | Changes every edge in the sprite | Selective, dark-coloured |
| Destination | A game engine wants tags and a sheet | Ask |
Procedure
preflight. If not ready, stop and tell the user — nothing below works without a live Aseprite.Read what already exists. If a sprite is open,
sprite_infoit. The user's existing canvas size and palette usually answer half the questions, and matching an existing project's style is almost always what they want.Draft the brief. Fill the table above from what the user said plus the defaults. Do not ask about things you can reasonably infer — "a Game Boy style knight" has already told you the palette and the size range.
Put it to the user in one message, as decisions rather than questions:
32×32, PICO-8 palette, 3⁄4 view, light from upper-left, selective dark outline. Knight in plate with a sword, facing camera. Say if any of that is wrong — otherwise I'll start.
One round trip, not five. If they said nothing about a detail, they probably do not care about it.
When the request is something new — a character, a prop, an animation —
aseprite:conceptfollows, and its offer goes in this same message: the decisions above, then the image-model prompt in one code block, then the choice between sending references and continuing without. The user answers once. If they correct a decision, fix the prompt to match before they copy it.Ask only what genuinely blocks you. If the sprite is for a specific game and you do not know its tile size, that one is worth asking. Light direction is not.
Record the brief in your working notes and hold to it. Every later decision either follows from the brief or is a mistake.
Show full SKILL.md (62 more words)Show less
Then
aseprite:concept for anything drawn from scratch — its offer is already in
the message above. Then aseprite:new to create the document, or
aseprite:draw if a suitable sprite is already open.

Turn a vague pixel-art request into a written brief — size, palette, view, light, outline style — and confirm it with the user before any pixel is drawn.
When should I use Brief?
Brief fits situations like: the request is open-ended (make me a knight) rather than a specific edit; tasks that involve Sprites and pixel art.
How do I install Brief in Claude Code?
Run `npx skills add with-pebbly/aseprite-ai-artist --skill brief -a claude-code`. Or copy the skill folder (skills/brief in with-pebbly/aseprite-ai-artist) into .claude/skills/brief in your project. Claude Code loads it when a task matches its description.
How do I install Brief in Codex?
Run `npx skills add with-pebbly/aseprite-ai-artist --skill brief -a codex`. Or copy the skill folder (skills/brief in with-pebbly/aseprite-ai-artist) into .agents/skills/brief in your project. Codex loads it when a task matches its description.
Can I use Brief in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add with-pebbly/aseprite-ai-artist --skill brief -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/brief, .gemini/skills/brief, .github/skills/brief and .opencode/skills/brief in your project.
What does Brief need to run?
SKILL.md names no scripts, command-line tools or credentials: Brief is instructions for the agent only.
Does Brief access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Brief safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Brief use?
Brief is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Brief use?
About 833 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Brief?
Skills that share tags, products or a category with Brief: Sprite Gen (aldegad/sprite-gen, 2.6k stars), Fal Assets (rehan-remade/universal-modder, 5.3k stars), Game Assets (glifxyz/glif-mcp-server, 212 stars) and Scenario Game Assets (scenario-labs/skills, 913 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
