- In the newly launched Claude Projects, Claude can’t type plain text anymore. Every message is a tool call to a new MCP server called hearthbot - which is why it can go back and edit. - Projects is not just parallel agents. It’s a proper team. A coordinator that can’t do any work itself, workers with their own repo, and a room where all of them report back - This room works a lot like Slack. Posts, edits, reactions , buttons, threads. Even the Slack etiquette is written down into Claude’s instructions.
