Agents at the Application Layer
summary
Mastra is a TypeScript framework that shows how real agents run: a weather agent using five mini calls a weather tool, streams deltas to a Next.js frontend, and uses observational memory to compress 3.1k tokens down to ~480; studio runs locally alongside a Hono API server with interchangeable SQL adapters. The demo wires tools, workflows, eval scorers and tool approvals into durable execution, cites 25k GitHub stars and a 100k user Indeed deployment, and demonstrates client-side tools updating UI state successfully.
