Observability interface for PraisonAI Agents.
This module provides the protocol and types for observability/tracing.
Implementations are provided by the wrapper layer (praisonai\_tools.observability).
Usage (simplest - recommended):
from praisonaiagents import Agent, obs
agent = Agent(
name="Assistant",
observability=obs.auto(), # Auto-detect from env vars
)
agent.chat("Hello!") # Auto-traces to configured provider
Alternative (explicit provider):
observability=obs.langfuse() # Langfuse
observability=obs.langsmith() # LangSmith
observability=obs.agentops() # AgentOps
observability=obs.arize() # Arize Phoenix
observability=obs.datadog() # Datadog

```
