Show HN: CATT 0.2.1: Test agents/services against a Muse/Instinct-alike, in CI

CATT (Consumer Agent Testing Tool) 0.2.1 is a testing framework that allows developers to test how AI assistants interact with their services by running scripted or model-driven agents against MCP servers, websites, or HTTP APIs. The tool supports emulation of Muse and Instinct-like assistants and includes features for checking service behavior, inspecting evidence, and comparing results across builds in CI environments. It functions as a surrogate that approximates an assistant's host environment rather than replicating its actual implementation.
