What it does

Game Assets is an agent skill from glifxyz/glif-mcp-server. Make art and media for a game you are building with Glif: character reference sheets, consistent characters, pixel-art sprite sheets with animation cycles, seamless and PBR textures, 3D models, item and ability icons, and trailers. Saves files where the engine expects them. Use when: "character sheet", "let's create a character sheet", "same character in every scene", "sprite sheet", "run cycle", "pixel art character", "tileset", "seamless texture for my game", "PBR materials", "3D model for…

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`). Compatibility notes: Requires the Glif MCP server at https://glif.app/api/mcp.

It sits in Game Development, covering Sprites and pixel art, 3D graphics and WebGL and Game assets and audio. It works with Godot, Three.js and Model Context Protocol. The repository describes itself as: Glif's hosted MCP server, plugin and skills for creating images, video and audio. Works with Claude, ChatGPT, Codex, Cursor and more. The licence is MIT.

When your agent uses it

  • : character sheet
  • Lets create a character sheet
  • Same character in every scene
  • Pixel art character

Example prompts

  • “character sheet”
  • “s create a character sheet”
  • “same character in every scene”
  • “/game-assets”

Requirements

  • Compatibility (from SKILL.md): Requires the Glif MCP server at https://glif.app/api/mcp.

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Set the style once
  2. Ask for engine-ready output
  3. Check before using

What it can do on your machine

Read from SKILL.md and the folder at commit 0c90bf7. 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

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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.

  • Compatibility

    Requires the Glif MCP server at https://glif.app/api/mcp.

    From compatibility in the SKILL.md frontmatter.

Context cost

Game Assets loads about 831 tokens when it runs. Until then it costs about 188 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~188
When it runs · the whole SKILL.md, loaded when a task matches
~831

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.

description
Make art and media for a game you are building with Glif: character reference sheets, consistent characters, pixel-art sprite sheets with animation cycles, seamless and PBR textures, 3D models, item and ability icons, and trailers. Saves files where the engine expects them. Use when: "character sheet", "let's create a character sheet", "same character in every scene", "sprite sheet", "run cycle", "pixel art character", "tileset", "seamless texture for my game", "PBR materials", "3D model for Unity/Godot/three.js", "ability icons", "game trailer", "I need a cool logo for my game". NOT for: the game's logo or app icon (use app-icons-and-logos), music and sound effects (use audio-and-video), store graphics (use app-promo-materials).
compatibility
Requires the Glif MCP server at https://glif.app/api/mcp.

Make game art that fits the engine and stays consistent. The user's explicit instructions come first, within host safety rules.

1. Set the style once

Before making anything, agree on:

  • art style: pixel art (and resolution, such as 32×32), hand-painted, cel-shaded, low-poly, PS1 retro, realistic...
  • palette and mood, and any reference art (upload it with upload_file)
  • the engine and folder layout: Unity Assets/Art/, Godot res://assets/, web games public/assets/

Start with a character reference sheet for each main character: front, side and back views, expressions, colors and key items. Every later asset uses it as a reference, so characters stay the same. Show it and let the user approve it first.

2. Ask for engine-ready output

AssetPut in the brief
Sprite sheetFrame size, frame count and layout (for example an 8-frame run cycle, 64×64 per frame, one row), solid background removed to transparent, plus a preview GIF.
TilesetTile size, which tiles (ground, edges, corners) and that edges match.
Seamless texture1:1, power-of-two size (1024, 2048 or 4096), tileable on every edge, no baked lighting or shadows.
PBR materialThe albedo plus normal, displacement and specular or roughness maps at the same size.
3D modelWhat it is, rough poly budget, and the file format the engine wants, such as GLB.
IconsOne sheet in a shared style, then each icon cut out on transparency at the size the UI uses.
TrailerLength, aspect ratio, key moments and music mood. It uses generated footage, so label it as a concept, not gameplay.
Show full SKILL.md (132 more words)Show less

Generation spends credits. A request for the asset is approval. Batch related assets in one compose_project call and keep using the same project_id so the style carries over. Share the projectUrl, and follow runs with get_job_status, passing the jobId as job_id.

3. Check before using

Download with curl -fsSL "<media url>" -o <path> into the engine's folder. Never overwrite existing art; add -v2.

  • Sprites: frames are evenly spaced and the same size, and the background is truly transparent. Slice locally if the engine needs single frames.
  • Textures: view one tiled 2×2 or 4×4 and look for seams.
  • 3D: open the model in the engine or a viewer, and check its scale and orientation.
  • Pixel art: import with point (nearest) filtering, no compression.

Report what you made, where it lives and the projectUrl.
