 - To rebase onto the base repo's main, you must add an `upstream` remote: `git remote add upstream https://github.com/<base-repo>.git`

+- **`claude-code-action` overwrites origin's fetch URL** to point to the base repo (using `GITHUB_REPOSITORY`). Any workflow that needs to push to the fork must set `pushurl` separately via `git remote set-url --push origin <fork-url>`, because git uses `pushurl` over `url` when both are configured. See `pr-review-responder.yml` and `claude-rebase.yml` for examples.
