A tool description is an interface

Build lab: write both halves of one tool description. The schema, checked by the harness on every call, decides which calls are valid; the prose, read by the model, decides which calls are aimed well. Your schema faces 14 test calls and a scripted model picks tools using your prose. Plus the earn-your-keep test for adding a tool at all.
