Lesson 9.3 · 4:10
The system that outlasts the tools
Goal: Separate what will change (models, harnesses) from what you keep (the four jobs and your habits).
Try it
Write your own one-page "system card," in your own words:
- The four jobs, one line each, with one example from your own project.
- Your four habits, one line each.
- The four questions you'll ask of any new harness.
- One next project you'll start this week, in one sentence.
You're done when your card fits on one page and someone who's never taken this course could understand it.
Recap
- Models and harnesses will keep changing. The four jobs won't.
- Your habits (direct, give context, check, save) work in any tool.
- Keep building small, finished things and share them.
Next: your own project. Bring it back to the community.
