Sam Bhagwat, Mastra's co-founder and chief executive, outlines a progression from model calls to tool-using agents, durable harnesses and always-on assistants. Harnesses add planning, background execution, interruption, steering and persistent sessions so work can continue beyond a single exchange.
Bhagwat describes the architectural shift from local execution to cloud sandboxes and team messaging. He uses the term claw for systems that notice external events, wake on schedules and learn from prior runs. Automatic skills and harness changes are emerging approaches, not settled answers about safe continual improvement.
His prediction is partly about user demand: people pull assistants into more tasks as capabilities expand. Bhagwat also expects consolidation, comparing it with mobile applications that survive because they are frequently used or provide substantial value. He advises builders to meet capability expectations while preparing for selective adoption rather than assuming every powerful assistant will retain users.
