From the workshop.

Anthropic launched claude.ai/design the same week I'd been sketching a new look for this site. I did the design work in the browser, exported the handoff bundle, pointed Claude Code at it, and got a production rebuild six phases later with zero new npm dependencies.

Two open-source UniFi MCP servers existed. Neither did what I wanted. So I built a third that combines their strengths, lazy-loads per product, and ships as a Claude Code plugin you can install with two slash commands.

I reviewed an AI-generated recommendation to convert my custom agents into 'captains' that spawn parallel sub-agents. Here's what I learned about factual assessment, corrected parallel structures, sandbox constraints, and when to use this pattern (or keep it simple).
