Show HN: We track 1,397 AI agents. 43 famous ones (402k stars) have gone dark (agentcrush.xyz)

A new report titled the "Ghost Index" has revealed that 43 once-popular AI agents, collectively boasting 402,000 GitHub stars, have gone silent, showing no public commits or activity for over 90 days. This indicates a potential drop in their ongoing development or engagement, highlighting a significant challenge within the AI community—while some projects may be stable or completed, their inactivity raises questions about ongoing support and innovation. The distinction between historical star ratings and current liveness is critical, as stars measure past popularity but do not accurately reflect a project's current viability. The Ghost Index employs a methodology that enables rigorous tracking of these agents, anchored in a verifiable hash for transparency. This report serves as a wake-up call, prompting developers and stakeholders to reassess their projects' activity levels and the sustainability of AI innovations in a rapidly evolving field.
