Running Claude Code dangerously (safely) (blog.emilburzo.com)

A developer shares their experience optimizing the use of the AI coding assistant, Claude Code, by employing the --dangerously-skip-permissions flag, which allows the agent to execute tasks without permission prompts. Recognizing the risks to their filesystem, they explored several isolation methods, ultimately settling on Vagrant for its ability to provide full VM isolation with a simple, reproducible configuration file, avoiding the complex pitfalls of Docker-in-Docker setups. This approach significantly enhances productivity and safety, allowing Claude to perform a variety of tasks—including building web applications, managing databases, and running Docker images—without the constant need for user inputs. The setup ensures protection against accidental filesystem damage while highlighting a vulnerability in the VirtualBox version used, which caused high CPU usage. The solution is particularly valuable for those in the AI/ML community who require a seamless and secure development environment while leveraging powerful coding assistants like Claude Code.
