Every Harness Will Become A Claw — Sam Bhagwat, Mastra
Agent harnesses will evolve into autonomous 'claws' — the next phase beyond current frameworks
“welcome to the harness era”
Sam Bhagwat, co-founder/CEO of Mastra (a TypeScript agent framework), argues we are in the 'harness era' where local, cloud, and open-source agent frameworks wrap LLMs into structured execution environments. He predicts this era is transitional — harnesses will become 'claws,' a more autonomous tier on the agentic spectrum analogous to moving from lane assist to full self-driving. The talk draws on 18 months of production agent deployments but the transcript cuts off before the core thesis is fully articulated.
