Story

AI SDK 7 adds a unified reasoning-effort option, per-tool typed context, MCP Apps support, built-in telemetry, and the headline WorkflowAgent for crash-durable agent runs plus a HarnessAgent API that drives Claude Code, Codex, and Pi from one interface. It targets the reliability gaps that break in-memory agent loops. The "harness outlives the model" framing keeps showing up.
