Code Review

This pull request replaces the basic busybox container in the agent runtime example with a Python-based HTTP echo server, updates the router URL in the PCAP analyzer deployment, and updates the Python SDK usage example to dynamically retrieve configurations from environment variables. The review feedback suggests refactoring the Python example to use context managers (with statements) for the AgentRuntimeClient instances to ensure robust resource cleanup instead of calling .close() manually.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Pull request overview

This PR makes the Python SDK AgentRuntime example runnable against the repository’s Kubernetes manifests by adding a minimal echo HTTP server with health probes, updating the SDK usage example to call that echo endpoint, and correcting the Router service address used by the PCAP analyzer example.

Changes:

• Documented the deploy/port-forward/invoke workflow for the AgentRuntime SDK example.
• Updated the AgentRuntime SDK example script to use env-driven runtime name/namespace and invoke the /echo endpoint.
• Fixed the PCAP analyzer example’s ROUTER_URL to point at the correct in-cluster Router service.
