Jack Dorsey's open source AI version of Slack wants to include GitHub

According to surveillance, Jack Dorsey's Block released Buzz. It's an open source collaboration platform for humans and AI agents that attempts to combine Slack's team chat with GitHub's code collaboration. Buzz provides channels, thread, private messages, voice, media sharing, automated processes, and Git hosting. Agents join as independent members and have their own identity and permissions. They can message, submit, and review code, and trigger workflows. The platform supports Claude Code, Codex, and goose. Buzz is based on the Nostr protocol. Messages, workflows, and Git actions are all signed and written to a unified event log. Teams can deploy on their own or use a hosted version provided by Block. The project uses the Apache 2.0 open source license. Buzz already provides macOS, Windows, and Linux clients, but the product is still in its early stages. The mobile terminal and some workflow approval features have not yet been completed.
