Every slide after: the same look
one long, messy message

What should the message say?

Mevoice message, shortened

So the AI series, lecture three went well, they liked it, and now lecture four, probably next Wednesday, and I want it to be, I mean, more about AI agents, or what do you think, or not agents exactly, I mean how to actually use an agent, because they like that the lectures are HTML and they want to know, I mean, how to make one, so maybe the lecture is a tour of making a lecture, and while we do it, like a tutorial, we explain the basics, prompt engineering, context engineering, me talking to it by voice, I mean, a project that has everything about me, letting the AI ask me what’s missing so it knows, and orchestration too, one model as the base that sends agents to do jobs, an agent that reviews another agent, critique, all of it, I mean, tips and tricks, and not many sources, only where we need them, and I’d like to give the doctors the skill too, so think about it and tell me the best way, and if you need anything, ask me.

Then · prompt formulas

You are an expert lecturer.

Rule 1: Be concise.

Rule 2: Use bullet points.

Format: 10 slides.

Task: AI agents.

Let it ask you first

Before you start, ask me what you need.
1A live demo in the hall?Yes, with a backup copy
2Which skill do I give them?A bigger one: the whole method
3Show my real chats?Yes, the most convincing part
4How long, and when?Next Wednesday, 20 minutes like Lecture 3?
5How long did Lecture 3 take?If you don’t remember, drop it
6Claude only, or others too?Claude only, plus one line: any tool works

Here’s a first outline: 22 slides, ~20 minutes, in 6 parts.

  1. Title
  2. The message, as it came
  3. The analogy: a brilliant new colleague
  4. Live: the room picks a topic, it builds

How did it make the pictures?

Claude can’t make pictures. So it used a tool that can.
