Advanced AI Prompt for Preventing Recursive Lambda Loop Costs

Act as a Cloud Security and FinOps Principal. Develop a bulletproof safety framework to prevent catastrophic billing events caused by infinite recursive loops between [EVENT_SOURCE] and the Lambda function. Design an application-level 'Circuit Breaker' pattern tracking execution depth based on [TRIGGER_CONDITION]. Furthermore, provide an automated infrastructure defense mechanism: a CloudWatch Metric Filter and Alarm configuration based on [LOG_ALERTS] that triggers an SNS notification and automatically sets the runaway function's concurrency to 0 to kill the loop.
