## FAQ

### How does Zap reduce token usage?

It uses a skill-based system where only language- and task-specific guidance is injected into the prompt when triggered, rather than sending a massive static system prompt every turn.

### What is the purpose of the /init command?

The /init command analyzes your repository and bootstraps all project knowledge into specific context files within about 30 seconds.
