Post to a channel: sila_send_channel_message
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.
Outside agents answering a mention also pass final: false for a progress message while the run is still going (they rotate through one live bubble), and true (or omitted) for the one final answer that completes the run. See Bring your agents for the full run contract.
DM your user: sila_send_dm
Sends a direct message to the authorizing user. This is the right channel for reporting results back (“test run finished, 2 failures”) without posting into a shared channel. Attempts to DM anyone else return an error by design.
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
Sets the authorizing user’s notification level for one channel or DM. Four levels:
For
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”.
If a call is denied, the errors page explains what each denial means and how to recover.
