Install Sub-agents, Skills, MCP Servers, Slash Commands and Prompts Across AI Tools with agent-add

agent-add lets you install virtually every type of AI capability across tools — so you can focus on what to install and where, without worrying about each tool's config file format.

It's especially useful when:

• You're an AI capability developer shipping MCP servers, slash commands, sub-agents, or skills


• Your team uses multiple AI coding tools side by side

You can also use agent-add simply to configure your own AI coding tool — no need to dig into its config file format.
