CHOOSE AND VERIFY
For an existing project, check whether the assistant can work with your repository, build commands and tests. For a new prototype, decide whether you need editable source code, an engine project or a hosted playable result. Ask it to implement one mechanic, run the build and show what changed before expanding the scope.
