I have done all of these things. The last time I did this, I wrote a self documenting bash script project.sh similar to the last Nix example with a list of commands and a help text and menu options. Another useful object is not just unix history but a tool like Rash in Python, advanced bash shell history stored in SQLite. There are many similar tools nowadays but then you can look for commands you run in this project directory structure in your cli history. Projects are not flat, so there may be specific commands needed in certain directories.
