6 capabilities
// What you can do with it
- Session management — resumable sessions so a run can pause and continue with full history.
- Persistent memory — a memory store (file or KV-backed) the agent reads at startup and writes facts back to between turns.
- Sub-agents — child agent definitions the orchestrator delegates to, each with scoped tool permissions.
- MCP integration — mcpServers config wiring stdio/HTTP servers and exposing their tools to the loop.
- Structured outputs — JSON-schema-validated final results instead of free text.
- Cost guardrails — a per-run token budget and max-turn cap that halt the loop and surface usage from the SDK's result message.
