"""Spike 5: Test OpenTelemetry tracing with Smolagents.

This spike validates:
1. openinference-instrumentation-smolagents can be installed and imported
2. OTEL tracing captures agent steps
3. Tool calls are traced automatically
4. Console export works for debugging

Run: uv run python spikes/spike_05_otel_tracing.py

Prerequisites:
    uv pip install openinference-instrumentation-smolagents opentelemetry-sdk
