Tool Isolation
Domain: Tools & Toolsets
Motivation
Tools operate with limited scope. The terminal tool cannot access .env. The file tool cannot write to system directories.
Concrete Example
terminal: cannot cat .env (redacted). file: cannot write to /etc/. Each tool has boundaries that protect the system.
Analogy
Different keycards in a hotel - your room key opens your room only. Tool isolation gives each tool limited access.
