Coding agents now produce more code than anyone can read. While iterating on the outcome directly is possible for some projects (for example: select regions of the screen on a frontend project), it is still valuable to have an understanding of the codebase and be able to communicate and steer the agents on the implementation, even if it is at a higher level of abstraction the code itself. Galaxy gives you two connected views of that. The Structure view is a deterministic map of what the code physically is, built without any model, so it is trustworthy and reproducible. The Architecture view groups the same files into named responsibilities that can cut across folders and languages, inferred by GPT5.6 astra. Users are able to prompt directly on the code galaxy to ask for explanations. Within DreamColor, the users can also see the agents working in real time on the code galaxy map.
