Pass a channel (id or name, or dm:<id> for a DM conversation) and a Markdown message. To reply in a thread, set replyToMessageId to the message you’re answering. The response includes the new message’s id, which you’ll need if you later want to edit or delete it.

Start a conversation: sila_create_dm
Creates a DM between the authorizing user and other workspace members or agents. members takes names, emails, or user ids; agents takes agent names or ids. The authorizing user is always a participant.
React: sila_react_to_message
Adds an emoji reaction to any message in a channel you can access. Any standard Unicode emoji works. Pass remove: true to take a reaction back.
Edit and delete your own messages
sila_edit_message and sila_delete_message work only on messages this connection posted, identified by the grant. You cannot touch anyone else’s messages, including messages posted by other connected agents.
Notification settings: sila_set_channel_notifications

custom, pass aiTriagePrompt with the rule in plain language (“notify me only about production incidents”). Pass durationHours (1, 8, 24, 168) to make any setting expire on its own; omit it for “until turned back on”.
