<Badge color="blue">AI Agent</Badge>

Context Events for PraisonAI Agents.

Provides context-level tracing for replay functionality.
Tracks context changes during agent execution for debugging and replay.

Zero Performance Impact:

* NoOpSink is the default (zero overhead when not used)
* Disabled emitter has near-zero overhead
* Uses **slots** for memory efficiency

Schema Version: 1.0
