Building with Claude — skills, plugins, and tools I actually use.
67 visual styles, 161 color palettes and a decision tree — describe the brand, get production-ready CSS.
TDD, debugging, code review, plan writing, parallel agents, git worktrees — 15+ workflows in one bundle.
Click, fill, screenshot, snapshot, run E2E tests — Claude drives a real browser from the conversation.
A note vault an LLM maintains as a living wiki — knowledge that compounds, instead of plain RAG.
