  "account": "FinGarage, a product developed as part of the Flip the Switch Hackathon, aims to address the challenge of managing cloud FinOps invoices. The $14,487/month billing spike on a single internal endpoint was a pain point for FinOps teams. FinGarage leverages Switch and Google Antigravity to bring Finance and Engineering together in a live environment.\n\nFinGarage consists of two agents: finops-agent and dev-agent. The finops-agent has exclusive access to invoice data and budget policies, while the dev-agent has access to the application code. Both agents work together to instrument the checkout-service, adding cost telemetry to every HTTP request.\n\nThe probes run in the Switch Room to detect cost inefficiencies and code quality issues. The golden accuracy probe checks for compliance with budget policies, and the golden accuracy probe verifies the financial accuracy of the code changes.\n\nThe dev-agent can make shortcuts to reduce costs, but if the golden accuracy probe detects a loss in accuracy, the finops-agent will block the fix. The final fix involves optimizing the SQL queries, caching LLM responses, and adding structured metric counters. This results in a 92.5% reduction in unit cost, a 25.7x improvement in latency, and a 100% golden accuracy rate. The finops-agent updates the Switch Room Document with the savings and attaches a receipt card as proof.",
