Summarize a git diff into a reviewer-facing changelog grouped by subsystem. Use when preparing a change review.
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
# Summarize Diff Use this skill when the user asks what changed in a branch or a pull request and wants a summary they can paste into a review. ## Steps 1. Run `git diff --stat` against the base branch to see which files changed. 2. Group the changed files by subsystem, using the top-level directory name. 3. For each group, read the diff and write one sentence describing the change. 4. Emit a markdown list with one bullet per group. Stop once the summary is written. Do not commit, push, or open a pull request.
Read the whole file at its exact version.
How to install
mdr add stbenjam/skillsaw/summarize-diff@sha256:aa4cb1eac79d75bfThe line at the top of this page pins the label git:20260806.0f41cce, 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.
