About the startup

Kaizen Agent is an open-source CLI tool that helps you ship better LLM apps by automating the boring parts of development: 🧪 Define test cases in a simple YAML file (input, expected output, pass/fail conditions) 🤖 Automatically run all test cases 🧠 If something fails, the agent analyzes and suggests prompt/code changes 🔁 It keeps retrying until the test passes 📦 Then it makes a pull request with the fix — ready to review No more endless trial and error. Just write your tests and let the agent do the rest.
