Outsourcing Responsibility: What do you do when your debugger fails you?

Dear KV, I’ve been assigned to help with a new project and have been looking over the admittedly skimpy documentation the team has placed on the internal wiki. I spent a day or so staring at what seemed to be a long list of open-source projects that they intend to integrate into the system they have been building, but I couldn’t find where their original work was described. I asked one of the project team members where I might find that documentation and was told that there really isn’t much that they need to document, because all the features they need are available in various projects on github.
