Agent skills
Backend and database Claude skills and agent skills
What backend and database skills do
Schema design, queries and the right way to use a specific database or backend platform. A skill is a folder with a SKILL.md: the agent reads its one-line description up front and loads the instructions only when a task matches, so a backend and database skill costs almost nothing until you need it. The 15 here come from Microsoft (.NET), Cloudflare, Supabase, Firebase (Google), Sanity, MongoDB, Neon, Prisma, Convex, Upstash.
