An internal wiki for engineers and that has a list of concerns with individual articles for solving known issues/tasks. Plus a culture of encouraging each other to write or update wiki pages when they have an issue. If you have the time and motivation to write an internal tool, you should also have the time and motivation to write down the how and why. If you want to make a tool a part of your process, document that process and where to use the tool.
