Actions and tools with least privilege

Lesson 4 of 8 · Custom GPTs for Your Business Workflows

In this lesson. Only the APIs the job needs, with confirmation for writes.

What you will learn

  • Read versus write
  • Confirmation
  • Least privilege

Walkthrough

You will map read versus write actions. Writes need confirmation. A GPT with a wide tool belt will use it. Least privilege is the design.

Work through the ideas in order. After each point, pause and connect it to a task you already do — a document, a workflow, or a feature you own. The goal of Custom GPTs for Your Business Workflows is usable skill, not a pile of notes.

If something is unclear, rewrite it in your own words before you continue. Teaching the step back to yourself is the fastest way to see gaps.

Practice

List actions for your GPT. Mark writes as confirm-required.

Keep the first attempt small. A finished example you can reuse beats a perfect plan you never run.
