Safety System

ShellSage has a two-layer safety system:

Hard Blocklist

The following commands are always blocked and can never run, regardless of context:

• rm -rf /, rm -rf /*, rm -rf ~
• dd if=/dev/zero, dd if=/dev/random, dd if=/dev/urandom
• mkfs, chmod -R 777 /
• Fork bombs: :(){ :|:& };:
• Piping untrusted URLs into a shell: curl | bash, wget -O- | sh

Danger Levels

Each proposed command is shown with a color-coded panel:

Level	Color	Indicator
safe	Green	🟢
caution	Yellow	🟡
destructive	Red	🔴

You always see the command and its danger level before being asked to run it. You can also press e at the confirmation prompt to get a detailed token-by-token explanation.

Switching Providers

shellsage config

This re-runs the interactive setup wizard where you can switch between Claude and Ollama, change models, and update your API key.

---

How It Works

1. ShellSage detects your OS, shell, working directory, and installed tools.
2. It sends your English intent to the configured LLM with a structured prompt.
3. The LLM responds with a JSON plan containing one or more shell commands.
4. ShellSage validates each command against the safety blocklist.
5. You confirm (or explain, or skip) each command before it runs.
6. If a command fails, ShellSage automatically attempts to self-correct using the error output.
