Will other builders hate using what you made?
Reviews your plan from the perspective of someone who has to use your tool, plug into your system, or set up your project.
If you're building something that other people will plug into — a service, a tool, a shared system — then those people are your users, and their experience matters just as much as any customer's. Bad builder experience means: confusing setup, unhelpful error messages, things that work on your machine but break on theirs, and documentation that doesn't exist.
When someone tries to use your tool and hits a wall, they don't file a bug report. They stop using it. Developer Experience Review catches these walls at the planning stage: Are the pieces intuitive and consistent? When something breaks, does the error message tell you what went wrong and what to do about it? Is setup straightforward? Is there enough documentation to get started without reading the source?
Run it on any plan where the end user is another builder — someone plugging into your system, using your tool, or setting up your project. It evaluates whether your interfaces are intuitive, your errors are helpful, your setup is minimal, and your documentation exists. You get back specific improvements, not vague suggestions.
Anytime you're building something other people will integrate with, configure, or extend. Internal tools count — future you is a builder who will be frustrated by present you's unhelpful error messages six months from now.
