Help Scout keeps adding channels — now a portal customers sign into
Two customer-facing surfaces landed in a week: two-way SMS through a customer's own Twilio number, and a Customer Portal where a company's contacts sign in to see support history raised across their organization. Underneath, the SLA system built out in May and June now drives workflows, views, and reporting. Per-inbox office hours, away auto-reassignment, and availability status on web and mobile fill in the operational layer.
Slack is shipping its developer platform to coding agents, not only to developers.
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.

The product is widening from an agent-side inbox into the places customers actually wait — SMS, WhatsApp, and now a signed-in portal with company-level visibility. Portal access sitting on Plus and Pro puts the newest surfaces on the paid tiers rather than across the board.
Expect the portal to pick up what adjacent surfaces already have — SLA status, more self-serve actions — and the channel list to keep widening rather than any one channel getting deeper.

The MCP and Skills plugin is the clearest signal of where this is going: Slack is packaging its own platform knowledge for consumption by coding agents, and naming Claude Code and Cursor as the first targets rather than shipping a generic endpoint. Meanwhile the SDK work is clearing debt that would get in the way, dropping axios for native Fetch, removing the deprecated Workflow Steps from Apps feature, and raising the Node floor to 20. Modern runtime, fewer legacy surfaces, then agent access on top.
The plugin ships for two named agent clients today, so the obvious next step is broadening that list or folding the skills into the CLI itself. The entries do not indicate whether Slack intends the MCP server to reach runtime app behaviour or stay a build-time developer aid.
