AI Skills
Teach an assistant which tool to use.
A model with 230 tools available still has to know which one answers the question in front of it. A skill is the packaged instruction that tells it — when to reach for a tool, what to pass, and how to read the reply.
What a skill contains
When to reach for it
The situations a tool actually answers, so the model does not call a DNS lookup to format JSON.
How to call it
The inputs that matter and the ones that usually do not.
How to read the output
What the response means, including the failure shapes.
What it costs
So an assistant can prefer the cheap tool when either would do.
Composable
Skills combine, so a task needing three tools does not need a bespoke prompt.
Portable
Works with the MCP server and with the hosted agent runtime alike.
Start with the MCP server
Connect a client, then add the skills for the tools you use most.
