Paste-first PR body — no GitHub App

Methodology: draft · optional AI · human review

Turn commit messages or a short diff into a structured PR body (Summary / What changed / How to test / Notes). For indie teams who want AutoPR-quality drafts without installing a GitHub App first.

1. What the engine owns

Structured PR body from paste. Demo is labelled Rule-based — never silent mock.

2. What optional AI may do

Polish sections when a key is configured. Upstream failure returns 502. No invented test steps beyond the paste.

3. What you must do

Verify Summary and test notes against the real change.
Paste the body into your host — PrGen does not install a GitHub App.
Keep humans accountable for review quality.

4. What we deliberately do not do

GitHub App install or CI auto-comment.
Replace code review or required reviewers.
Guarantee merge approval.
