Claude Design MCP in Claude Code: keep design and code in sync

One command wires the Claude Design MCP into your terminal. Pulling a design into the repo, or pushing the repo up as a project, stops being copy and paste.

#174

Claude Design in Claude Code: the /design command that hands you an editable canvas

#173

#172

Playwright MCP in Claude Code: give it eyes and it fixes its own work before you ask
