To ensure these tools have genuine utility, I follow a simple rule: a tool is only added here after it has been successfully integrated into at least two distinct projects. By abstracting away repetitive configuration and infrastructure “plumbing”, these tools reduce developer cognitive load and allow teams to focus on core features rather than boilerplate.
