LLMs Should Never Do the Math: A New Databricks Tool Enforces That Rule
A new open-source tool, databricks-cost-leak-hunter, prevents LLMs from performing arithmetic on billing data, instead using SQL joins against Databricks' system tables for accurate cost calculations. The tool, built as a skill for Claude Code plugins, achieved a B grade (88/100) with zero errors. Its key architectural rule is that the LLM decides what to analyze but never computes dollar figures.

The tool's strict separation of LLM reasoning from arithmetic is a smart architectural pattern that could prevent costly hallucinated financial reports in enterprise AI deployments.
