The three arcs
Three stages: Foundations → Craft → Capstone.
The arcs are Mosaic's macro structure. You move through them in order.
- Arc I — Foundations (teal). Free. Prompting, terminal basics, your first conversations with Claude in the browser. No code yet.
- Arc II — Craft (blue). Paid. Python, file editing, running real programs on your machine with Claude Code. You start building things.
- Arc III — Capstone (purple). Paid. You pick a real project, scope it, build it, deploy it. You finish with something you can show people.
The arcs build on each other. Prompting muscles from Arc I directly power Arc II. Arc II's skills are what make Arc III possible.
