How I Wrote an AGENTS.md for an Open Source WordPress Plugin

A developer wrote an AGENTS.md file for an open-source WordPress plugin to help AI coding agents work correctly. The file provides a source of truth for the project, including build and test commands, file locations, and coding conventions. Without this file, agents can be expensive and destructive, making incorrect suggestions and changes. The AGENTS.md file is now a standard for many AI coding agents and should be included in any project using these tools.
