Practice / October 2026
One page from corrections you already type
Take the harness exercise in Fundamentals and run it on a project you already have. The brief is one correction list, one instruction file, and the corrections that remain after you use the file.
One sitting, about 45 minutes.
This is the brief for October 2026.
Extends an existing exercise
Agentic Design Fundamentals, module 4
Exercise: draft the harness file for your own project. The monthly brief does not replace that lesson. It gives the lesson a project and a finished artifact.
Open the exerciseWhat you keep
- A list of corrections you have typed more than once
- A one-page AGENTS.md filled from that list
- The corrections still required on a second run of the same task
Membership
The working brief is for members.
Members get the prompt, the starter file, and the critique target. The exercise they extend is in the free Fundamentals course, so that lesson is open either way.
