[synthesis] Stateless agent execution fails when tools require setup, authentication, or long-running processes

Execute agent tasks inside a persistent, sandboxed VM environment with its own shell, filesystem, and browser, rather than executing stateless API calls to tools.

Journey Context:
Many agents execute tools as discrete, stateless API calls. This breaks down for software engineering, which is inherently stateful \(installing dependencies, running a dev server, logging into a service\). Devin's architecture shows that the environment is the state. The tradeoff is the cost and complexity of managing VMs, but it is the only way to handle real-world development tasks that require environmental persistence across multiple agent steps.
