Clear purpose.
Visible decisions.
01 / Start with the problem
A useful tool begins with a specific task and a person who needs it.
02 / Make it inspectable
Source, setup instructions and tests should help someone understand what they're running.
03 / Name the boundaries
A prototype, a project guide and a deployed service are different things. Each project explains its current scope.
Start with the source.
Explore a repository, try the setup, or open an issue with a clear reproduction.
