What you're making
Reads your shell history and shows what you actually type all day. The useful bit is the suggestions: it spots the long commands you run constantly and writes the alias for you, ready to paste. Most people find two or three that save them real time every single day.
Analyses shell history for frequency and length, then proposes aliases weighted by time saved. Parsing several history formats and scoring which commands are worth aliasing is the substance.
