AI SDK 7: Agent Development Standardized

Short summary

AI SDK 7 consolidates agent development with provider-agnostic primitives (typed tool context, runtime context, file/skill uploads, MCP support) and production infrastructure (durable execution, approval gates, reasoning control), eliminating custom orchestration boilerplate. Requires Node.js 22+, ESM migration via codemods. LangSmith ships on SmithDB (12x faster trace queries); Vercel Harness unifies five coding-agent runtimes. Verdict: ship for production agents; evaluate Harness for provider flexibility; defer if prototyping.

• •AI SDK 7 provides provider-agnostic primitives and production infrastructure to eliminate custom agent orchestration boilerplate
• •Node.js 22+ and ESM-only required; codemods assist migration; LangSmith observability backend now 12x faster
• •Harness package unifies five coding-agent runtimes; ship for production, evaluate for provider mobility, defer if prototyping
