Design Claude Skills
2 394 design skills from 450 authors. They decide how things look — layout, type and interface behaviour. Half of them fit into 1 928 tokens or less — that is what one costs your context window when the agent loads it. 316 ship runnable scripts rather than instructions alone. 2 of them cannot work without an MCP server, most often rube. We also found 395 copies of these same skills sitting in other people's repositories — counted once here, not 395 times.
