Bob is a Non-Intelligent console assistant. Bod doesn't try to replace any existing shells or build systems. It is designed to extend them. Often when you have few projects to work, they use different commands or build systems to maintain. To organize it, often you have to add or global aliases to your shell or create scripts which grow over time to maintain it. Bob trying to solve this problem by adding the ability to create local aliases for each directory. It is doing this by creating configuration files (in YAML) with defined aliases in each directory. When Bob is executed in a selected directory, it reads configuration file (if exists) for selected directory for aliases.
