Having designed a good number of internal tools for teams of developers I couldn't agree more.
Earlier I had the tendency to "leave the guts" open, thinking my users were developers and would want that. All it did was put obstacles in my teammates actually doing their work. My teammates must use the tools I made for them to achieve work the company needs them to do, they don't want, nor should they want to, fiddle with a little tool they won't find anywhere else.
I still leave a lot of escape hatches, but I try to design the internal tools in such way as to make the users fall into a pit of success.
Edit: also, error messages, error messages, error messages and auto suggestions for common errors
Edit 2: also the number of people only addressing the examples in the post rather than the spirit of the post is... disappointing.
