 The settings dialog supports search — type to filter settings by name. Changes take effect immediately.
 
+*(v1.0.70+)* The `/settings` command and the `/model` command both support **`--repo` and `--local` flags** for explicitly scoping which layer of settings you want to view or edit:
+
+```
+/settings --repo    # view/edit repository-scoped settings
+/settings --local   # view/edit local (user-level) settings
+/model --repo       # view/edit the model pinned for this repository
+/model --local      # view/edit your personal model preference
+```
+
+These flags mirror the **Repo** and **Repo (local)** scope tabs available in the `/settings` dashboard (v1.0.71+), making it easier to manage per-repository vs. user-global configuration without ambiguity. In v1.0.71+, the `/settings` dashboard also shows **Repo** and **Repo (local)** tabs alongside the existing user-level view, giving you a unified place to see which settings are applied at each layer.

 `/pr auto` is ideal when you have a PR with failing tests or linting errors — let it work through failures one at a time while you focus on other things. `/pr automerge` extends this further: it continues until all CI checks pass, required reviews are approved, and the PR is successfully merged. Both commands can be monitored and stopped from `/loop` or `/every`, which register the running automation as a scheduleable loop task.
 
+The `/delegate` command creates a **delegate PR** — a pull request that the coding agent works on autonomously. By default, the delegate PR targets your current branch. Use `--base` *(v1.0.69+)* to specify a different target base branch:
+
+```
+/delegate                      # create a delegate PR targeting the current branch
+/delegate --base main          # create a delegate PR targeting main
+/delegate --base release/2.0   # target a specific release branch
+```
+
+This is useful when you want to hand off a task to the coding agent on a specific branch — for example, backporting a fix to an older release branch or targeting a long-lived feature branch for automated work.

 The `/share html` command exports the current session — including conversation history and any research reports — as a **self-contained interactive HTML file**:
