Unclear Which slash commands are refused to relay participants is not stated.

What

Claude Code now checks slash commands sent by relay participants, people taking part in a session through a relay, and refuses some of them. The message reads that the command isn't available to a relay participant. Commands sent over Remote Control keep their own wording saying they aren't available over Remote Control.

A command that gets queued again is now marked so it is not treated as a slash command a second time.

Why

This limits what relay participants can run in a session.
