Claude Code Development skills :)

Flowy lists 20564 skills in the Development category for Claude Code, across 1018 plugins. A skill is a folder of instructions an agent loads while you work. Every one here shows what is inside before you install, who wrote it, and whether it is Auto-invoked, meaning a FLOW.md router fires it as you prompt.
