Build a PowerShell AI Agent — From Scratch

AI agents feel like magic right now.

That’s usually a sign you haven’t looked under the hood yet.
In this livestream, we’ll build a simple AI agent in PowerShell from scratch. No frameworks, no hand-waving, no vibes-only abstractions.
Just the core pieces that actually make an agent work.

We’ll walk through:

• What an “agent” really is (minus the mythology)
• Tool calling and control flow, in plain PowerShell
• How agents run commands, inspect output, and decide what to do next
• Why tools like Cursor and Windsurf feel magical until they don’t

Think of it like a magic trick.
The first time, it looks impossible.
Once you understand the mechanics, the spell breaks.

This isn’t about replacing engineers.
It’s about curiosity, and keeping up with how the work is actually changing.

If you’ve been meaning to “eventually” build your own agent, this is that moment.

Skip Advent of Code. Build the agent. Feel the power.

My bias, quietly stated: once you build one yourself, a lot of the hype loses its grip.
