summarize-diff skillA
summarize-diff is agent-read markdown (skill) from stbenjam/skillsaw: Summarize a git diff into a reviewer-facing changelog grouped by subsystem. Use when preparing a change review..
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.
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@git:20260806.0f41ccemdr add stbenjam/skillsaw/summarize-diff@sha256:aa4cb1eac79d75bfPin 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.
