 ## Pull Request Commands
 
-Pull requests belong to a **repository**, specified with `--repo` (required for `pr-create`, optional filter for `pr-list`). `pr-get`, `pr-open`, `pr-vote`, `pr-abandon` and `pr-complete` work by PR ID and resolve the repository automatically, so they need neither project nor repo.

 > `pr-list --mine` and `pr-vote` need your user ID, which is captured during `config --login` / `config --pat`. If they report a missing user ID, re-run `config` to refresh it.
