CATT 0.2.1 (Consumer Agent Testing Tool) helps developers test how an assistant interacts with their service. It allows running scripted or model-driven agents against various targets like MCP servers, apps, websites, or HTTP APIs. CATT checks service actions, inspects evidence, and compares results across builds, supporting emulation targets like Muse and Instinct. It also offers features for scenario scaffolding, readiness checks, and protocol verification, ensuring robust testing in CI environments.
