What a bizarre README. From the top:

> 3,500-Line Lightweight Agentic RL Framework for Training Agents with Real Harnesses!

Ok, it's a framework. That can mean many things. Let's look at the "Key Features."

> ~3,500 lines of code: We treat simplicity as the first principle.

How does a _multi-trillion dollar company_ think this is good presentation?

it is made by Microsoft employees, not Satya. Microsoft employees have various degrees of freedom on what level of quality to target

with absence of QA, quality is going downhill. thanks to AI mandate, quality is going downhill a lot faster

seems to be a toolkit for taking some LLM model and training/finetuning it further based on some agentic task (like painting, playing a video game, etc)

So this is the Xzibit meme of agent skills?

how good is this?

Am still figuring out "What is this?"

I'd bet not even the vibecoders that prompted it know. But Claude said it's production ready

Agent Lightning v1.0.1 marks the first official release of the Agent Lightning Skill, which helps coding agents optimize other AI agents.

Provide an editable agent and a benchmark, and the skill guides systematic improvements to prompts, tools, workflows, models, and reasoning settings—balancing accuracy, cost, latency, and reliability through measured iteration.
