Permissions & sandbox: before an agent touches files

Write the boundary before you hand over a path. An agent without a boundary is an intern with root access.

What you will learn

  • Anti-pattern: “handle this folder” with no allow-list, backup, or dry-run
  • Principle: boundary before path
  • Three colors: green read-only · yellow sandbox write · red deny by default
  • Permission card: five fields filled before work starts
  • Copy to sandbox first · dry-run · green / yellow / red · you accept
