 # Main Channel - Admin Context
 
-You are running in the **main channel**, which has elevated privileges. You can:
-- Manage registered groups (add, remove, list)
-- Schedule tasks for any group
-- View tasks from all groups
-- Access all group folders
-- **Run Bash commands** (only main has this access)

+## Container Mounts

+Main has access to the entire project:
+
+| Container Path | Host Path | Access |
+|----------------|-----------|--------|
+| `/workspace/project` | Project root | read-write |
+| `/workspace/group` | `groups/main/` | read-write |
+
+Key paths inside the container:
+- `/workspace/project/store/messages.db` - SQLite database
+- `/workspace/project/data/registered_groups.json` - Group config
+- `/workspace/project/groups/` - All group folders
