Put the OpenAPI file in the repo, generate the tools and mock from it, and let the agent read the current contract every sessblogs.powerduck.com

Both expose tools to the agent, but only the generated one stays coblogs.powerduck.com

The agent then calls typed tools that trace to real operations, instead of workinblogs.powerduck.com
