Remembering one thing is easy, remembering all the things is not. With an agentic CLI I don't need to remember anything, other than if it looks safe or not.
But I still need to remember what to search for, and they're not always straight forward. The agent writes and organizes the scripts/commands I use frequently, and references them as a starting point. It all started by having an agent look at my shell history.
It's faster than I am, and it knows things like ffmpeg flags I don't care to memorize.
Even opencode running on a local model is decent at this.
