SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Full safety mode for shell operations that warns before destructive commands and blocks edits outside a defined boundary.

Core Features & Use Cases

  • Destructive command warnings — alerts before executing rm -rf, DROP TABLE, or other risky commands.
  • Edit boundary enforcement — restricts edits to a user-specified directory and blocks edits elsewhere.
  • Coordination with safety tools — relies on sibling /careful and /freeze scripts to implement guardrails in production-like sessions.

Quick Start

Enable guard mode and specify the directory that edits should be restricted to.

How do destructive command warnings work in interactive shell sessions?▼

Destructive command warnings work by monitoring interactive shell sessions and alerting you before risky commands execute. The system coordinates with sibling safety scripts to enforce guardrails and provide reliable fail-safe behavior.

Do I need sibling safety tools to enforce guardrails in production-like sessions?▼
