A practical course for developers and technical founders. By the end you will have built an agent that reads a codebase, calls tools and ships a change — the same patterns KnowCode uses in client work.
What's in the course
-
1 What an agent actually is
Free preview
The loop: model, tools, context. Why chat is the wrong mental model.
-
2 Setting up the harness
Enrol to watch
Project layout, the tool registry, and your first tool call.
-
3 Tools that earn their keep
Enrol to watch
Designing tool inputs the model can actually use; error shapes that recover.
-
4 Context, cost and caching
Enrol to watch
Keeping a multi-turn tool loop cheap without losing the plot.
-
5 Shipping it
Enrol to watch
Sandboxing, review gates, and putting the agent in front of real users.
