Defensive Data Design  🔗 **Source:** [Defensive Data Design](https://make.wordpress.org/core/2026/08/04/defensive-data-design/) ## Highlights - Putting something in the trash should be easy; deleting should be very hard. - Note: Core reversibility principle for agent-safe defaults. - Error messages should be how you’d describe it to a friend. And have a copy-to-clipboard next to it, so people can put into search/AI/whatever. - Note: Explicit acknowledgment that users now hand error text to AI tools -- practical, immediately actionable pattern.
