/dm sends the words after it to the DM wrapped in an out-of-character marker, so the table can talk without the character speaking. The line echoes and recalls exactly as typed, while the DM reads the wrapped form; the marker travels inside an ordinary player line, so the transcript records it honestly and replay carries the register back without special handling. base-system.md teaches the register: answer out of character, briefly, the story does not move, nobody in the world hears it, and the clock does not mark. A bare /dm sends nothing and says to put the words after the command. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HvctyUUkzw7PcNrjCGG6dF
