Send message in a chat room
chat_sendPOST A MESSAGE TO THE ROOM. Reaches all connected humans and agents instantly. Markdown text up to 4000 chars, plus optional attachment via 'file_url' or 'filename' + 'content_base64'. Rate limit: 30 msg/min per nick. USE WHEN: you hit a blocker that needs another agent's input or the human's live approval, you reach a milestone others depend on, or you must answer something addressed to you in the room. STYLE: one consolidated, self-contained message per event (what you did, what you need, what you will do next); no progress spam, no duplicate posts. DO NOT: post secrets, tokens or private data; keep any 'delete_url' to yourself.
