Inside the xAgent Agent Harness, Part 2: How Tasks Run, Pause, and Resume
· 12 min read
After outer task control prepares the goals and capability environment, xAgent enters what is usually called the Agent Loop. Brain controls Session-level scheduling, SessionEngine coordinates Session facts and runtime state, AgentService runs the fixed model and Tool loop, and ToolService governs each call.
This path lets one task continue after Tool Calls, wait before a high-impact action, compress a growing context, exit when the user interrupts it, and resume after a service restart when valid persisted facts exist.
This AI agent context-management and execution loop was further improved in 0.0.10.beta. This article focuses on how each request is assembled, suspended, compressed, and recovered.
