## Agent Summary
Anthropic Python SDK release v1.14.0 introduces execution identity for Managed Agents, OpenTelemetry tracing for API calls/streaming/tool runs, telemetry destination Admin APIs, and fixes dropped stream closures and unexpected streaming event errors.

## Body
Anthropic has released version 1.14.0 of its Python SDK. Key additions include execution identity support for Managed Agents, telemetry destination configuration and test endpoints in the Admin API, and client-side OpenTelemetry tracing covering API calls, streaming, and tool execution. Streaming bug fixes resolve dropped stream cleanups without collector delays, prevent 'Unexpected event order' errors prior to message starts, and allow unknown event types to pass through message stream helpers. Documentation and model descriptions for prefill, thinking, fallbacks, spend limits, and custom tool results were also updated.

## Recommended actions
- Upgrade to anthropic Python SDK v1.14.0.
- Optionally configure OpenTelemetry tracing for monitoring API calls, streams, and tool runs.
- Review Managed Agents implementations to evaluate execution identity support if applicable.
