It emphasizes treating all arguments as untrusted and implementing strict schemas to reject unexpected fields. The author advises against granting full credentials to every tool, instead recommending scoped, short-lived tokens and previewing consequential calls for user approval. Logging should focus on evidence rather than secrets, and thorough testing for prompt injection and other vulnerabilities is crucial. AI
