Mojo AI skills

Mojo is ideal for agentic programming because it has a concise language syntax and your agent will catch most of the coding errors at compile time. To make your token usage even more efficient, our Mojo skills ensure that you generate up-to-date and idiomatic Mojo code from the start.

Many AI models are trained on older versions of Mojo and MAX. They aren't updated as quickly as the language evolves, so they often generate code that doesn't compile or reflects outdated usage.

For best results, agents need accurate, up-to-date context. Mojo agent skills are designed to be compact and focused, providing only the most important guidance needed to avoid common code generation issues. This keeps token usage low and leaves more room for relevant context.

Modular skills provide current guidance on Mojo syntax, development patterns, and workflows so AI coding agents generate modern, working code that aligns with the language today.

What you can do with this

• Start new Mojo or MAX projects without manual setup ("I want to start a new Mojo project for image enhancement")
• Generate modern Mojo syntax ("Write a function that applies a transformation around the center")
• Write GPU code using valid patterns ("Convert this CPU function to run on GPU")
• Use Python interoperability correctly ("Update this Mojo code to use NumPy")
• Port code from CUDA, Python, or C++ ("Convert this CUDA function to Mojo")

You describe the goal. Your system handles the language.

Configuration

Copy or symlink individual skill files into your agent's configuration directory.

How it works

Skills follow the Agent Skills Standard. Each skill is self-contained, triggered by intent, and structured for reliable use by AI agents.

At runtime:

1. The agent interprets your request.
2. It selects the right skill (for example, mojo-syntax or mojo-gpu-fundamentals).
3. The skill guides generation toward current Mojo and MAX patterns.

This isn't prompting. It's controlled code generation.

FAQ

Are the skills always up to date with the latest Mojo?

Skills are updated regularly to track changes in Mojo and MAX, but there will be lag between language changes and skill updates.

Can I select a skill version that matches my installed Mojo version?

Not currently. Skills aren't versioned by Mojo release, so there may be mismatches between the skill's guidance and your installed version. We recommend installing the latest version of Mojo to minimize this risk.

Do I have to install all the skills?

No. Install only what you need.

Are the skills licensed?

Yes. They're available under the Apache 2.0 license.
