Codegeist: A Real AI Coding Workflow in an Open-Source Java Project
Codegeist is an open-source coding agent developed in Java.
This full developer walkthrough shows the real engineering workflow behind the project: start from the public GitHub repository, clone its shared devcontainer and agent kits, open the workspace in VS Code, start OpenCode, and follow a small real task through planning, implementation, native build, focused tests, review, and a local Git commit.
The point is not only the result. The repository, runtime, agent rules, proof, and review path stay visible and reproducible.
