# TwinEthos

> TwinEthos is a corpus of AI-law rules anchored to the official text of each law, regulation and standard, with the guards to add to code that uses AI, for coding agents and AI assistants. Each rule cites its provision, who it applies to, and when. Informational data, not legal advice. Rules have not been reviewed by a lawyer. TwinEthos recommended guardrails are its opinion, not law.
