data-agent-rules

About

data-agent-rules is a set of rules, skills, and a destructive-SQL guard for AI coding agents including Claude Code, Codex, Cursor, Gemini CLI, and Copilot. It aims to stop agents from scanning, overwriting, or inventing data in a warehouse. The README reports a 162-run DuckDB eval in which Claude Haiku 4.5 without the rules deleted every row of an orders table, mis-scaled prices, and fabricated customer countries.
