I found a high-quality collection of Claude Code skills—someone directly extracted their 23 daily-used skills from ~/.claude/skills/ and made it public, without any "tutorial" packaging.

What impressed me most is grill-me: four sentences in total, making the AI interrogate each branch of the plan like an interrogation until reaching consensus. Ask only one question at a time, and don't ask about anything that can be found in the code.
Reading their skills is more useful than reading tutorials; you can see engineers truly using AI as an extension of their brain.
Planning categories (domain-model / zoom-out / ubiquitous language) are especially good, serving as a thinking scaffold before writing code.
I copied grill-me into my own skills, and next time I have a new idea that needs validation, I’ll throw it in and interrogate it 😆
