-This plugin registers one unified optional tool: `dirigent_tools`.
-To use it, add tool allowlist entry for either:
-- tool name: `dirigent_tools`
-- plugin id: `dirigent`
+When the current speaker NO_REPLYs, the moderator bot sends: `<@NEXT_USER_ID>➡️`
 
-Supported actions:
-- Discord: `channel-private-create`, `channel-private-update`, `member-list`
-- Policy: `policy-get`, `policy-set-channel`, `policy-delete-channel`
+This is a non-semantic scheduling message. The scheduling identifier (`➡️` by default) carries no meaning — it simply signals the next agent to check chat history and decide whether to speak.
