SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides full safety by issuing destructive-command warnings and enforcing a directory-scoped edit boundary to prevent accidental changes to critical systems during development or debugging.

Core Features & Use Cases

  • Destructive-command warnings: prompts before executing dangerous commands like rm -rf, DROP TABLE, or force-push.
  • Edit-boundary enforcement: restricts edits to a user-specified directory, blocking changes outside that path.
  • Safe collaboration: can be used alongside other safety modules (/careful and /freeze) to create a robust safety envelope for prod or live debugging.

Quick Start

Ask for the directory to protect and enable guard mode, then run the setup to activate destructive-command warnings and the edit boundary.

Frequently Asked Questions about guard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent accidental destructive commands during production debugging?▼

Preventing accidental destructive commands during production debugging requires issuing warnings before executing dangerous commands like rm -rf or DROP TABLE. This enables guard mode to prompt for confirmation, blocking high-risk edits.

What is an edit boundary and how does it protect critical systems?▼

An edit boundary restricts file modifications to a user-specified directory, blocking any changes outside that protected path. This prevents accidental edits to critical systems during development or debugging sessions.

How do I set up a directory-scoped edit boundary for development?▼

Setting up a directory-scoped edit boundary involves specifying the directory to protect and enabling guard mode. Running the setup activates destructive-command warnings and enforces the edit boundary for that path.

Does guard mode work with other safety modules for live debugging?▼

Guard mode works with other safety modules, coordinating with sibling safety modules to create a robust safety envelope. This combination ensures comprehensive protection during live or production debugging.

What's the best way to block force-push and similar dangerous operations?▼

The best way to block dangerous operations like force-push is to enable a safety-focused tool that issues destructive-command warnings. This intercepts high-risk commands before execution, preventing accidental data loss.
