Shellfirm is a command-line tool that intercepts potentially dangerous shell commands, prompting the user with a challenge to confirm execution. It helps prevent accidental data loss or system misconfigurations by acting as a safety net before commands are run.

Who should use shellfirm?

Shellfirm is intended for developers, system administrators, and anyone working with command-line interfaces, especially those who frequently execute powerful or destructive commands. It is also designed for integrating with AI agents to add a layer of safety to their operations.

How does shellfirm prevent risky commands?

Shellfirm differs by offering context-aware escalation, applying harder challenges when connected via SSH, running as root, on protected git branches, or in production Kubernetes clusters. It also provides safe alternative suggestions and integrates with AI tools for enhanced analysis and safety.

When should I use shellfirm?

You should use shellfirm whenever you want an extra layer of protection against executing dangerous shell commands, such as rm -rf, git push --force, or Kubernetes delete commands. It's especially useful in development, staging, and production environments where mistakes can have significant consequences.

What types of commands does shellfirm monitor?

Shellfirm monitors over 100 patterns across 9 ecosystems, including filesystem operations, Git, Kubernetes, Terraform, Docker, AWS, GCP/Azure, Heroku, and databases. It supports 8 different shells, including Zsh, Bash, Fish, Nushell, and PowerShell.
