About skills
Creating skills seems to me the new frontier of programming. Here are some ideas about them:
- They're not scripts, so we should stop using the "do this and then do that" approach.
- Human written skills > AI written skills. Writing by hand is more costly, so less junk is bound to land there.
- Evaluate them — are they actually useful? Without evaluation the path to usefulness is murky.
