+## Integrated commands
+
+All commands use global registration with server and bot-DM contexts. `/help`
+reads this same registration metadata, so its command list stays in sync.
+
+| Command | Function |
+| --- | --- |
+| `/help` | Command guide and website link |
+| `/today` | Daily manual/count/task check-ins |
+| `/habits` | Create, edit, schedule, archive, restore, permanently delete |
+| `/tasks` | Add, rename, schedule, delete routine tasks |
+| `/history` | Inspect and correct dated progress, including archived habits |
+| `/reminders` | Named schedules, multiple times, quiet hours, enable/disable |
+| `/settings` | Timezone and reminder delivery status |
+| `/progress` | Private graphics, confirmed snapshot sharing, live-image controls |
+
+After the deployment controller installs a release, register its definitions:
+
+```sh
+cd /opt/minabot
+sudo docker compose exec -T app bun scripts/register-discord-commands.ts --apply
+```
+
+Registration upserts individual global commands and preserves unrelated commands.
+The public key and interactions URL are one-time setup; adding commands requires
+rerunning registration after their handlers have deployed.
