Before changing unread code: '이 구조 설명해줘', 'X는 어떻게 동작해', '이건 어디에 둬야 해', '왜 이렇게 됐어', '이 결정 배경이 뭐야', 'teach me this', '이거 제대로 이해하고 싶어', '이 변경 이해시켜줘', 'feature map 만들어줘', '기능 지도 그려줘', '지금 뭐가 구현돼 있는지 정리해줘'. Verify maps: verification-skill. An orchestrator dispatches it instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Explain code
Four modes read code and explain it. None of them edits code. Pick the mode from the ask, read its reference, and follow it. A caller names the mode in the Skill args (`how: <question>`); without one, pick it from the question and say which you picked.
| Mode | When | Reference |
|---|---|---|
| how | How code works: runtime flow, architecture, where something belongs ("how does X work", "X는 어떻게 동작해", "이 구조 설명해줘", "이건 어디에 둬야 해"). Run it before editing a subsystem no one here has read. | [references/how.md](references/how.md) |
| why | Why code is this way, from history, PRs, tickets and chat ("왜 이렇게 됐어", "이 결정 배경이 뭐야", "why did we do X"). Run it before deleting or loosening code whose reason is not written down, and to find the change behind a regression. Explaining what the code does never answers why. | [references/why.md](references/why.md) |
| teach | Someone new to a body of work wants to understand it ('teach me this', "이거 제대로 이해하고 싶어", "이 변경 이해시켜줘"). It weaves how and why into one account. A single how or why question is that mode. | [references/teach.md](references/teach.md) |

How to install
mdr add jeongjaesoon/agent-skills/explain-code@sha256:23b6647661401338The line at the top of this page pins the label git:20261107.d41ee90, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
