Show HN: Cc-hindsight – turn your Claude history into a reusable prompt library

I built this because I wanted to learn from my past session and align with Claude Code better right from the first prompt. I was spending a bunch of my session steering, restating the same preferences, answering questions that I felt I've answered before. By the end of a session I can now have a prompt library entry for that kind of work. I might try to help turn these into skills quickly as well.
