Slack shipped Slack Code, giving every coding agent its own channel with inherited permissions.

Announced August 26, it's a dedicated channel type for long-running agent work that an agent can spin up from an existing conversation and carry that context into. Because it's built on the normal channel model, visibility, membership, notifications, approvals and permissions come for free rather than being rebuilt per agent (Slack). Live for teams using Claude, Devin, GitHub Copilot and Vercel, with ChatGPT coming, while the underlying APIs including the code.channels:manage scope stay in beta for select partners. Reusing the existing permission model instead of inventing an agent ACL is the correct engineering call and the reason this will stick.
