KalyanKS-NLP/llm-engineer-toolkit ? reverse-engineered prompt

Build me a polished GitHub README for an LLM engineer toolkit repo, like a curated reference guide for people working with LLMs, agents, RAG, fine tuning, evaluation, monitoring, prompts, safety, and embeddings.

I want it to feel like a friendly resource hub, with a clear title, a short intro, quick links to each section, and nicely formatted tables that list library names, short plain English descriptions, and links. The main goal is to help someone quickly find the right tool for a task without reading a huge wall of text.

Please make it look clean and professional, with a few small badges or social links near the top, and a simple structure that is easy to scan in GitHub. If you need to check current names or docs for the libraries, look them up online. Keep it focused on useful tools, not a tutorial, and make sure the categories are easy to navigate.
