46% of Open-Source AI Agents dropped from rankings in 28 weeks

I have built a leaderboard that tracks open-source AI agents and found something pretty interesting.

In the last 28 weeks almost 42% of the agents that were ranked on my leaderboard fell completely off the list. Which seems to be a pretty high churn rate.

I am tracking GitHub activity metrics like recent commit volume and star velocity.

I believe I am showing a robust breakdown of the open-source AI Agents that have staying power and are providing meaningful benefits to it's users, but are there any other metrics that I should be pulling in?
