# Dojos



## What's a dojo? [#whats-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.

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

Each dojo is a workspace package under `dojos/` in the [main repo](https://github.com/tomsiwik/dojocho), so it's easy to see exactly what your agent is being told.

## Available dojos [#available-dojos]

* **[effect-ts](/dojos/effect-ts)** — 700+ Effect-TS patterns, structured around the official patterns repo.
* **[pydantic-agents](/dojos/pydantic-agents)** — building agentic tools with Pydantic AI.

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