Summary
In its July 20, 2026 platform update, Vercel added native Slack agent support to the Chat SDK, plus new adapters for X and Discord Components V2, letting developers ship the same agent across multiple messaging surfaces. Agent Runs also began displaying subagent activity for better observability.
What changed
On July 20, 2026 Vercel's Chat SDK gained native Slack agent support and X and Discord Components V2 adapters, and Agent Runs started surfacing subagent activity.
Why it matters
Native multi-surface adapters lower the cost of meeting users where they already work, turning a single agent definition into a Slack, Discord, or X presence without bespoke integration glue. Subagent visibility in Agent Runs addresses a growing operational gap as agents fan work out to child agents.
