What are decision traces in a context graph? How they reveal agentic reasoning
Blog post from Neo4j
Decision traces are structured, persistent records that explain how AI agents reached decisions by linking outcomes to reasoning steps, tool calls, policies, conversations, and other relevant context. Stored as reasoning memory within a context graph alongside long-term enterprise knowledge and short-term conversation history, they can support explainability, debugging, compliance audits, consistency, learning, and collaboration among multiple agents. Unlike application logs, which track events, or LLM traces, which detail individual model runs, decision traces focus on why a decision was made and can be retrieved as precedents for future similar tasks. Neo4j Agent Memory provides SDKs, framework integrations, and APIs for explicitly capturing, completing, inspecting, and searching these traces in a graph, enabling teams to review agent behavior and give agents reusable decision history.
