 - **Auto-detection:** Tenant type is auto-detected from `gitOpsEngine` in `ksail.yaml` when `--type` is omitted.
 - **Registration:** Pass `--register` to automatically add the tenant to the nearest `kustomization.yaml`.
-- **GitHub scaffolding:** Use `--git-provider github` and `--git-repo` to scaffold a tenant repo. The token is auto-resolved from `--git-token`, `GH_TOKEN`/`GITHUB_TOKEN` env vars, or GitHub CLI config (`gh auth login`). If no token is found, scaffolding is skipped with a warning and the command succeeds.
-- **Flux OCI:** `--git-repo` is required for Flux OCI sync sources even without scaffolding — it builds the `OCIRepository` URL.
+- **PR delivery:** Pass `--delivery pr --git-provider github` to open a pull request against the platform repo instead of committing directly. The platform repo is auto-detected from `git remote origin`; override with `--platform-repo`. Set the PR target branch with `--target-branch`.
+- **GitHub scaffolding:** Use `--git-provider github` and `--tenant-repo` to scaffold a tenant repo. The token is auto-resolved from `--git-token`, `GH_TOKEN`/`GITHUB_TOKEN` env vars, or GitHub CLI config (`gh auth login`). If no token is found, scaffolding is skipped with a warning and the command succeeds.
+- **Flux OCI:** `--tenant-repo` is required for Flux OCI sync sources even without scaffolding — it builds the `OCIRepository` URL.
 
 **Commands:** [`ksail tenant`](/cli-flags/tenant/tenant-root/)
