Claude Advanced Guide: Builder
Connect Claude to your tools and your code.
By Paul B · Edition 1, November 2026
Level 3 moves you from using Claude to building with it. You learn to connect Claude to other tools, package repeatable methods as skills, delegate multi-step work and call Claude from your own code, with a person always kept in control.
Or get all four levels for A$47 — save A$18 with the complete set.
