# Author from Claude

Send this to your agent after installing the Build endpoint:

> Add the Spinrun Build MCP server and list the agents you can author. Read the catalog first; never invent a name.

The loop is catalog, validate, put, test. Review run output before copying anything into instructions.


> **Credits and confirmation:** Test runs spend workspace credits. Confirm with the person you work for before spending them.
