// WARNING: DefaultAzureCredential is convenient for development but requires careful consideration in production.
// In production, consider using a specific credential (e.g., ManagedIdentityCredential) to avoid
// latency issues, unintended credential probing, and potential security risks from fallback mechanisms.
// Create the agent using AsHarnessAgent. The FileAccessStore is explicitly set to the
// sample's working/ folder (copied to the output directory) so it works regardless of cwd.
// Unused features are disabled.
