Built-in tools
Use first-party tools for browser control, shell/file work, GitHub, web fetch/search, and more.
Tool packages
Built-in packages are enabled per agent. Common packages include browser automation, computer use, GitHub, web fetch, web search, and shell/file editing tools.
Container dependencies
Tools can require apt packages, commands, display services, or environment values. The daemon folds those requirements into generated Dockerfiles.
Enable only what you need
Start with the smallest tool set that can complete the task. Add more tools after the agent behaves predictably.
