+Background helper.
+
+Usage:
+
+- `/btw ask <question>` to start a background child session and post the result back here later.
+- `/btw todo <text>` to append a todo to the current session immediately.
+- `/btw status` to list child background tasks for the current session.
+
+If no subcommand is provided, treat the remaining text as `ask`.

+# dev-brendan branch
+
+This branch is a personal build maintained by [@brendandebeasi](https://github.com/brendandebeasi).
+
+It tracks `upstream/dev` (sst/opencode) with open PRs from the anomalyco org
+cherry-picked on top. It is rebuilt automatically and should never be submitted
+as a PR to sst/opencode or anomalyco/opencode.
+
+## Updating
+
+```bash
+bash update-dev.sh
+```
+
+This fetches the latest upstream/dev, auto-discovers open PRs from anomalyco on
+sst/opencode (skipping drafts and WIP), applies unique commits in topological
+order, installs deps, and force-pushes to brendandebeasi/opencode.
+
+## Adding a PR
+
+PRs are discovered automatically via `gh pr list`. To track a specific PR that
+wouldn't be auto-discovered, edit the override section in `update-dev.sh`.
