pr-prep

name	pr-prep
description	Prepare a branch for a pull request and draft its title and body. Use when a branch is ready for a PR or when asked for a PR title and description.

Run AGENTS.md, "Before opening a pull request" (every item) and the pull request prose rule under "Patches and commits": title and body say what and why, nothing the commits already say, no "Test plan" section, no em dashes. On top of it:

• When @type/@treturn changed, generate the docs (ldoc .) and check the links land on types, not functions.
• Compare git diff against git diff -w for stray whitespace; bash tools/checks/pre-commit covers the trailing blank line on staged files.
• Fixup commits stay unsquashed unless squashing was explicitly requested; the maintainer reviews them before they are folded.
• After any force-push, re-read the title and body against the branch as it now stands.
