 ## Rules
 
-- A command can only be registered if at least one manifest menu item declares
-  that exact `command` id.
-- Missing command handlers are a no-op when the user clicks the menu item.
+- There is no separate `contributes.commands` collection. A command can only be
+  registered if at least one manifest `menuItems[].command` or
+  `slashCommands[].command` entry declares that exact id.
+- A missing command handler is surfaced by the host as a retryable reload error;
+  menu clicks must never fail silently.
 - A handler owns precondition checks and feedback. See
   [Commands And Feedback](commands-and-feedback.md).
 - Menu item `when` expressions are evaluated by the host; unsupported or false
