explain-diff skillF

explain-diff is agent-read markdown (skill) from toongri/oh-my-toong-playground: Use when someone must actually understand a code change before acting on it — reviewing an unfamiliar PR, onboarding onto a subsystem through its history, or handing a large agent-authored diff to a human. Triggers include "diff 설명", "PR 설명해줘", "이 변경 이해하고 싶어", "explain this change", "코드 변경 설명 문서", "변경 퀴즈"..

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

Latest version
mdr add toongri/oh-my-toong-playground/explain-diff@git:20260918.dba3f1f
Exact content
mdr add toongri/oh-my-toong-playground/explain-diff@sha256:147f2c555993298a

Pin 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.
