A Game of Coding Agents
An interactive simulator that explains the core concepts of Claude Code through practice. The agent writes the code; you set the tasks, follow its work and make the decisions.
The simulator is made for a computer screen. Open this page on a computer to play.

- Plan mode: plan first, then code
- The context window, and what to do when it fills up
- Project rules in CLAUDE.md and AGENTS.md
- Seeing what the agent changed, and rolling it back
- Project history in git

The task
A website for a small pottery workshop. The owner has a note, a price list and a folder of photos, but no website. Over the full game the site goes from an empty folder to a finished project you can download.
The full game is in Russian for now. The English version is on its way.

Claude, Claude Code and related names are trademarks of Anthropic and are used here only to name the product this simulator teaches. The app window in the game is a simplified recreation for learning, not the real app. The agent’s replies are scripted; your prompts are checked by a third-party AI model, not by Claude.
