Dojos

What's a dojo?

A dojo is an installable training pack for a specific stack. It bundles:

• Katas — small, ordered exercises that teach one idea each.
• Sensei prompts — the system instructions that make your agent behave like a coach instead of an autocompleter.
• Tests — the agent runs them so you don't have to remember to.
• Rules — guardrails that keep the agent from solving the kata for you.

npx dojofoo add dojofoo/effect-ts    # install a dojo into the current repo
npx dojofoo add dojofoo/pydantic     # multiple dojos coexist
claude /kata                  # start practicing

Each dojo lives in a public repository under the dojofoo organization, so you can inspect exactly what your agent is being told and courses can release independently from the platform.

Available dojos

• effect-ts — 700+ Effect-TS patterns, structured around the official patterns repo.
• pydantic-agents — building agentic tools with Pydantic AI.

More dojos are easy to add — see the source of any existing one for the layout.
