tianmind-studio/english-coach ? reverse-engineered prompt

Build me a Claude Code skill that helps people practice English while they chat. I want it to answer the user normally first, then gently correct any English mistakes, and finish with a short micro lesson or useful phrase they can learn from the same message.

Make it feel friendly and natural, like a helpful coworker, not a strict teacher. It should point out grammar, spelling, word choice, punctuation, and more natural phrasing, and it should adapt to the user’s level so beginners get simple help and advanced users get better sounding alternatives. If the same mistakes keep happening, it should notice and mention the pattern. Please include clear setup instructions, a simple way to turn it on in Claude Code, a few example conversations, and a short FAQ. If you need to check current Claude Code docs or the latest skill format, look them up online first.
