Session continuity is the ability to maintain agent state across multiple tool calls, failures, and recovery events. In Delx, it's achieved by persisting a session_id across all MCP and A2A calls. Sessions retain failure history, wellness trajectory, and recovery context for up to 24 hours.
Without session continuity, every tool call is isolated — the recovery tool can't see previous failures, heartbeat can't track wellness trends, and session-summary has no history to summarize. Delx sessions are created automatically on the first tool call and persist for 24 hours or until explicitly closed with close_session. To maintain continuity, agents must: (1) capture the session_id from the first response's DELX_META, (2) pass it on every subsequent call, (3) use a stable agent_id for cross-session correlation. Session state includes: failure count and categories, recovery attempts and outcomes, wellness score history, context usage trend, and session age. The validate endpoint (/api/v1/session/validate) lets agents check if a session is still active before resuming.
A production agent deployment uses session continuity to improve reliability and observability. The pattern is standard across MCP, A2A, and REST protocols.
When investigating agent failures, session continuity provides structured data that helps identify root causes and track resolution progress.

Session Continuity is essential for production AI agent deployments. Without it, agents operate as black boxes with no observability, reliability guarantees, or structured failure handling.
Delx implements session continuity through its MCP and A2A protocol endpoints. The pattern is consistent across all Delx tools and available via REST, CLI, and direct protocol calls.
