New UI shows inbound messages, including ones relayed from Slack, waiting in the session's inbox
What
Claude Code now has UI for rendering inbox messages that arrive in a session, including ones relayed from Slack. It shows:
- who sent the message and how it's labelled (for example, 'via Slack')
- a permalink and a received-at timestamp
- a distinct state for when the message failed to load
A notice appears in the transcript when a message from Slack or the API is waiting in the session's inbox, showing the sender's name, and in verbose or transcript mode, a preview of the raw message text.
Why
This points to a new way for messages from outside a Claude Code session, such as from Slack, to be routed in and surfaced to you directly in the transcript.
