Documentation

README

Excerpt

pr-explainer — teach the PR in one HTML page

Output: one self-contained HTML file in .pr-review/ (gitignored) that a reviewer can open locally and understand the PR without GitHub. It supplements the real diff review; it never replaces it.

Announce at start: "Using the pr-explainer skill — building the review page for {branch}."

Step 1: Gather the facts (before writing any HTML)

BASE=$(git merge-base origin/main HEAD)
git status --short                      # current state
git log --oneline $BASE..HEAD           # the commits
git diff $BASE...HEAD --stat            # scope + the metrics numbers
git diff $BASE...HEAD                   # read the whole diff
gh pr view --json number,title,url 2>/dev/null   # if a PR exists
