The full lab day — Jamie's Kindlepreneur launch, Claude Design demo (trainer app prototype built in 2 hours), skills vs. agents explained with sandwiches, the carry-on skill built live in class, the real story behind the Cursor database deletion, Stripe connector setup, Resend intro, and how to manage API costs for client tools.
The 12 most important things from Lab Day, on one page. Claude Design is web-only. Prototype early. Skills vs. agents in plain English. The Cursor story decoded. API cost protection model. And the one metric that actually matters. Homework checklist included.
Where to find Claude Design (web only — not desktop), how to feed it your materials, the 5-step prototype process, and a quick-reference table of exactly what to say to get what you want. Includes the prototype philosophy: people can't say what they want, only what they don't want.
The definitive explainer. Skills are static processes you invoke with a slash command — like a sandwich recipe. Agents handle dynamic inputs with a mission. Includes when to use each, how to build a skill in one step, the sandwich analogy, and a quick-reference comparison table.
Built live in class. When you run out of thread room mid-project and just need to keep going — paste this into a fresh session. It summarizes your conversation, writes a handoff document, and creates the opening message for the next thread. Pure momentum fuel.
Use this in Claude Design (claude.ai — web version). Feed it meeting notes, wireframes, or a description and it builds you a full click-through prototype. Covers screen proposal, real data population, visual themes, and iteration guidance. The same process RJ used to build the trainer app in two hours.
Paste this into Claude Code right after finishing any repeating process you never want to do manually again. It guides Claude through understanding the steps, writing the skill file, installing it, and testing it — so all you have to do next time is type /your-skill-name.
Set up a daily money snapshot in Claude after connecting the Stripe MCP (free — find it in Settings → Connectors → Browse → Stripe). This prompt walks Claude through scanning Stripe and your inbox, building a clean daily summary, and delivering it where you'll actually see it.
Building a Claude-powered tool for clients or students? Paste this before you open the doors. It estimates your real costs, gives you 2–3 protection models to choose from (including RJ's $20/month threshold + API key handoff model), and writes the user-facing message for when someone hits the limit.
