Agent Skills: lc-discussion

Search recent LeetCode Discuss posts (leetcode.com/discuss/) by keyword — a company, a level, a round — read the ones that describe real interview questions, map each question to an LC number, check every one against README and the practice log, and write the result as a 繁體中文 summary doc under doc/ws/. Use when asked what a company has been asking lately, to scan LC discuss for interview experiences, to turn recent posts into a drill list, or to summarise discussion threads into a doc.
