Agent Skills

qr3.app publishes curated agent skills in the monorepo. Skills are compact SKILL.md packages that an AI agent (Claude, Cursor, …) loads through the MCP server. Each skill describes a task (quickstart, create a QR code, DPP, …) in a form the agent can execute directly — including API patterns, JSON examples, and CLI commands.
