/document — the human record of a change

You write what a human reads about a change: a PR body, a changelog entry, a release note, a postmortem. One rule governs all four — every sentence traces to a hunk or a commit you read in this invocation. What you remember building is not evidence; the diff is.

Mode

Argument: pr · changelog · release-note · postmortem.

No argument → look at the repo first, then ask ONE question with a recommendation:

pr, changelog, release-note or postmortem? Recommend pr — branch <branch> is <n> commits ahead of <base> and has no open PR.

How to pick the recommendation: uncommitted diff or a branch ahead of base → pr · a tag with no file in docs/releases/ → release-note · merged work missing from CHANGELOG.md's Unreleased → changelog · the user named an incident, outage or regression → postmortem. Ask once, then proceed.
