llm-echo 0.5a0

llm-echo 0.5a0 is a debug plugin (a tool that helps developers test code) for LLM that provides a fake AI model called "echo" for testing purposes instead of running a real LLM. The new version adds a "-o thinking 1" option to simulate reasoning blocks (the internal steps an AI uses to work through problems) and is compatible with LLM 0.32a0 and higher.
