GitHub 122K-star Skills adds Teach to turn a working directory into a stateful learning space

GitHub 122K⭐的Skills推出新技能「Teach」：把工作目录变有状态学习空间

GitHub’s 122K-star Skills repository added Teach, which turns a working directory into a stateful learning space using MISSION.md, lessons/, learning-records/, and reference/ files to track goals, lessons, learned items, and reusable notes.

Why it matters: HKR-H/K/R pass via a concrete agent-memory workflow and named file structure, but the source is a single X summary with no benchmarks, maintainer detail, or user results, so it sits near the featured threshold.
