Five-Stage AI Agent Engineering Roadmap: State Machines, MCP, Build a Server from Scratch
ramagetime · x · 2026-10-19
The quoted long tweet lays out a learning roadmap for AI Agent engineers (the tweet claims you'll never be unemployed once you master it):
- Stage 1, Architecture and State Machines: learn DAGs, cyclical workflows, LangGraph, Temporal, and state serialization; practice multi-step agents, using state machines to implement loops/branches/pausing and crash recovery instead of brittle while True chat loops.
- Stage 2, Tool Calling and MCP: learn JSON-RPC, strict Pydantic schemas, MCP server/client architecture, and dynamic tool discovery; practice by writing a raw MCP server from scratch.
- Later stages aren't fully shown in the original thread; the main poster simply replied "This" to endorse it.
