Nikunj Kothari 最爱的两个 Claude Code 默认技能

My two favorite default skills on Claude Code, still, that seem relatively less used are a) /insights and b) /playground..

For insights, I have a regular cron job that runs this now every two weeks. It tells me all the best ways to upgrade my setup. I pair it with X bookmarks that show all the new ways to build a software factory. It's a self improving loop on how I use Claude Code + what the industry thinks I should move to.

For playground, it's the best way to visualize what's happening in the workflow. I ask it to show me architecture of esoteric Github's to simulating a full learning loop on my side project. My new favorite thing is to pair Codex + Claude Code on this skill and ask it to find dead code, hot pathways, latency improvements.

Give it a shot and tell me what you think!
