Every Harness Will Become A Claw — Sam Bhagwat, Mastra
The evolution of AI agents is moving from localized 'Harnesses'—tools used for coding and task execution—to persistent, always-on services called 'Claws.' This transition involves imbuing agents with initiative, external connectivity (like a heartbeat), and continual learning capabilities. The speaker proposes Steinberger's law: every harness will expand until it becomes a Claw, driven by the desire for powerful, integrated developer experiences.
Key takeaways
