typescript

I have shipped Mastra across six TypeScript codebases over the full 1.x line — a market-intelligence API, an autonomous-CMO product, a crypto trading agent, a personal assistant. This is the comprehensive operator playbook: memory's four layers, tools and workflows, supervisors, MCP on both ends, RAG and evals, the free server and auth layers, observability, the whole 1.x migration history, and the production bugs that taught me the most.

Vercel open-sourced eve at Ship London — a framework where an agent is a folder of files. We built 75 agents on it and ran an adversarial review. Here's what holds up, what breaks, and the stateful-on-stateless tension the launch posts skip.

Cursor shipped @cursor/sdk in public beta on April 29 — the same harness that powers the IDE, scriptable from TypeScript. A working developer's tour of every surface, with code, gotchas, and ideas.

Fred Schott shipped Flue — a TypeScript framework that treats the agent harness as a first-class build target. Updated for the 1.0 Beta rewrite through beta.4, the new Actions primitive, @flue/react, the Cloudflare runtime deal, the Vercel-backed eve rival, and a fellow framework author's critique of what Flue makes first-class.
