In May 2025, Alex Johnson standardized the HTML XPath API within the sublime-security/sublime-rules repository by renaming the beta.html_xpath field to html.xpath across all detection rules. This refactor, implemented using YAML and leveraging expertise in XPath and detection rule development, maintained existing functionality while aligning the API with consistent naming conventions. The change improved developer onboarding and reduced future maintenance risk by ensuring traceable, issue-aligned updates. Alex’s work focused on API design and careful change management, resulting in a more stable and user-friendly interface for rule authors. No bugs were reported or fixed during this period, reflecting a focused scope.
