Explain a code change, its reasons, effects, trade-offs, and verification limits.
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 diff Explain the change so the user can understand its behavior and maintain it. Manual mode is repository-read-only; `--visual` may write only to system temp. Use the requested worktree, branch, range, pull request, patch, or packet. Default to the current worktree. Inspect the implementation, request, relevant decisions, verification, review verdict, and evidence limits. Use runtime data and logs when they settle a material claim. Label absent or stale evidence **Unverified change**. For `--visual`, read [visual mode](references/visual-mode.md). Explain the result, prior behavior, reasons, important failure cases, operational effects, and trade-offs. The explanation must stand alone without requiring the user to open the repository. Explain public or operational names before using them. Include implementation detail only when it helps the user's purpose. Use a diagram or concrete example when it makes the behavior clearer. ## Optional dialogue When the user wants an interactive explanation, ask applied questions one at a time. Ask the user to predict behavior, make a decision, or diagnose an observable result. …

How to install
mdr add reidemeister94/development-skills/explain-diff@sha256:d59211e668f237e7The line at the top of this page pins the label git:20260919.a9f7da5, 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.
