learning-coach skillB
learning-coach is agent-read markdown (skill) from yennanliu/investskill: Explains any InvestSkill output like a mentor — every metric in plain words, why it matters, its good / bad range, and the lesson that teaches it — then asks 3–5 Socratic questions and "what would change your mind?". --level beginner / intermediate, --lang zh-TW, and a --quiz mode that drills a Learning lesson.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add yennanliu/investskill/learning-coach@git:20260924.ce71682mdr add yennanliu/investskill/learning-coach@sha256:0071cba30b11e227Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
