Mint Three.js Skills is a set of instructions, packaged as an agent skill, that helps AI coding assistants build 3D web apps and games with Three.js. It is not a library you import into your code, instead it teaches a coding agent, such as Codex, Claude Code, or Cursor, how to approach building a Three.js project well, and it is meant to be used together with a separate tool called Mint MCP, which the same company provides for generating 3D assets. Installation is a single command line that installs the skill for whichever coding agent you use, with specific commands shown for Codex, Claude Code, and Cursor, plus a generic command for any other agent. After that, you separately connect Mint MCP through its own setup page so your agent can generate 3D assets as part of the same workflow. Once both pieces are installed, you use them by writing a plain-language request to your coding agent that mentions both Mint Three.js Skills and Mint MCP by name. The README gives three example requests: building a general 3D app such as a product configurator with model variants and camera presets, building a polished game such as a hover-racing game with a full playable loop and production assets, or working on an existing project to inspect it, fix rendering or interaction issues, and verify the changes. The README states that this project combines and adapts three other open source Three.js agent skill projects, generalizing them beyond just games and tailoring them specifically to work with Mint MCP as the 3D asset pipeline. The README itself is brief and does not go into further detail about what specific techniques or conventions the skill teaches.
