Give agents a quick, practical overview of Counterfact so they can safely edit Counterfact-generated projects.
Counterfact generates a working mock API from an OpenAPI/Swagger specification. It creates route handler files and types, then runs a live server with hot reload and a REPL.
routes/ and types under types/._.context.ts files.scenarios/ and REPL scenario commands.routes/ as the place for HTTP glue (status code + response mapping).
