LLM-Agents-Ecosystem-Handbook vs sema

LLM-Agents-Ecosystem-Handbook: This handbook provides a production-oriented guide for building, evaluating, securing, and deploying modern LLM agent systems. It covers the entire agent stack, including concepts, provider and skill ecosystems, prompt engineering, memory, safety, and observability, along with templates and runnable examples.; sema: Sema is a Lisp dialect that integrates LLM agents as core language primitives, providing a robust runtime that handles common agent scaffolding like retries, caching, and tool dispatch. It compiles to a fast bytecode VM, allowing LLM-powered scripts to be concise, shipped as single binaries, and easily understood by coding agents.
