TypeScript agents now ship with durable execution, tool approvals, multimodal support, and provider-agnostic reasoning control—replacing scattered prototype patterns with standardized workflows.

Summary
Developers building AI agents gain first-class persistence, approval gates, and observability primitives required for production deployments. Migrating eliminates custom orchestration boilerplate and vendor lock-in on reasoning features.

Implementation verdict
Breaking changes require Node.js 22+ and ESM-only imports; codemods automate most migration. Worth upgrading immediately if shipping agent workflows; prototype-phase projects can defer. Risk: provider reasoning behavior varies—test inference costs and latency per provider before committing.
