8 620 development skills from 759 authors. They write and change code. Half of them fit into 1 831 tokens or less — that is what one costs your context window when the agent loads it. 1 206 ship runnable scripts rather than instructions alone. 42 of them cannot work without an MCP server, most often rube. We also found 1 166 copies of these same skills sitting in other people's repositories — counted once here, not 1 166 times.
