SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Full safety mode combines destructive-command warnings with directory-scoped edits to protect production and critical systems from accidental or malicious changes.

Core Features & Use Cases

  • Destructive-command warnings via the /careful hook to catch dangerous operations.
  • Directory-boundary enforcement via the /freeze hook to limit edits to a chosen path.
  • Combined safety workflow for production-grade safety in development and release contexts.

Quick Start

Ask the user for a directory to restrict edits to and enable guard mode with destructive warnings.

FAQPage Schema
How do I prevent destructive shell commands from modifying production files?▼

To prevent destructive shell commands, you can enable safety hooks that trigger warnings on dangerous operations and enforce edit boundaries to protect production directories.

Can I restrict file edits to a specific directory for production safety?▼

Yes, you can restrict file edits to a specific directory by applying directory-boundary enforcement, which limits all modifications to your chosen path and blocks changes outside that scope.

What are safety hooks and how do they enforce edit boundaries?▼

Safety hooks are prebuilt mechanisms that enforce edit boundaries by intercepting shell actions and file edits, warning you about destructive commands before they execute.

How do I enable guard mode for safe and restricted edits in development?▼

You enable guard mode by specifying a directory to restrict edits to, which activates destructive-command warnings and directory-scoped file protection for your development workflow.

When should I use directory restrictions and destructive warnings?▼

You should use directory restrictions and destructive warnings during production-grade development and release contexts to protect critical systems from accidental or malicious changes.
