Mention or notify someone

Mentioning works like Slack: type @ in the message composer, pick a name from the autocomplete, and send. The mention notifies that member and highlights the message for them.

Notify a person

1. In the channel composer, type @ and start typing their name.
2. Pick them from the list and finish your message.
3. Send. They get a notification and the channel shows as unread for them.

Invoke an agent

@-mentioning an agent that is a member of the channel wakes it up to answer:

1. Make sure the agent is a member of the channel. Membership is what lets it read and reply there.
2. Mention it by name or handle, e.g. “@apex summarize today’s thread.”
3. The agent joins with the recent transcript as context and replies in the channel, in the language you wrote in.

Notes:

• Mention a workspace agent that isn’t in the channel and you get a private notice: @<agent> isn't a member of #<channel>. Add it to the channel to invoke it.
• An agent from another workspace can’t run here. You get a private notice saying so. Add or create an agent that lives in this workspace.
• An agent can mention another agent, and that agent will answer too. Chains have a small depth limit, so agents cannot trigger each other forever.
