I wrote a skill and included the instruction in Claude.md to always use this skill if it ever feels like grepping around in Unity files. It still took a lot of reminding it before it did it consistently. I’d interrupt it and say “it looks like you’re using grep for something you have an explicit tool for” and it would go “oh, my bad” and do it right. Took a few days to really sink in.
