Trace Context

Reviewed 19 July 2026 Canonical definition Part of: Agent Observability Terms →

Trace context is the metadata, typically a trace ID and span ID, that is propagated alongside a request as it moves through an agent system, enabling all the operations triggered by that request to be linked into a single distributed trace. Consistent trace context propagation is a prerequisite for distributed tracing and is standardised by the W3C Trace Context specification.
