Protecting Against Autonomous Agent rm -rf Commands

Protecting Against Agent rm -rf Commands

AI coding agents can run shell commands. Sometimes they run rm -rf by mistake. This deletes files forever. While of course I always read and approve all tool calls manually, by hand, and never let my agents work except under direct supervision 100% of the time, sometimes I miss things.

How It Works

1. Hooks catch rm -rf before it runs
2. Refuse the command with a clear error telling you to use trash

# Function to display usage information
usage() {
    echo "Usage: $0 /path/to/input.mp4 [ /path/to/output_directory ]"
    exit 1
}

# Check if at least one argument (input file) is provided
if [ $# -lt 1 ]; then

My writing process

Stages of my writing process

• Collecting material: For a number of topics that I may write about in the future, I have text files where I collect information as I come across it during coding, on the web, on Twitter, etc.

• Outline: The collected material is my starting point. I rearrange it into an outline which I refine until I’m happy with it. Refining includes adding/removing/rearranging items and doing more research when I notice gaps in my knowledge.

• Skeletal draft: I add bullet points and code examples until almost all of the content exists at least in skeletal form. This process often uncovers knowledge gaps and flaws in the structure of the content which I then can fix.
