A maintenance review before adding a WordPress filter plugin
Check ownership, update practice, data model, removal cost, and fallback behavior.
Before installing a filter plugin, write down the problem in platform-neutral terms. Name the content type, taxonomy or field, expected item count, required controls, and fallback behavior. This prevents a product demo from defining the requirement.
Review who maintains the package, how updates are delivered, and how quickly your team can test a release. Record the PHP and WordPress versions in the test environment. Never test an unknown package for the first time on the public site.
Inspect the data model. A filter that stores categories in a private format can make later migration expensive. Prefer normal content relationships when they meet the requirement. Check what remains if the plugin is disabled: content, shortcodes, blocks, styles, and database records.
Test the failure path. With scripts blocked or a request interrupted, the visitor should still see a useful page or a clear link. Finally, document removal. A plugin choice is easier to approve when the team knows how to leave it.
Use the current official WordPress Plugin Handbook as the starting point for plugin structure, security, privacy, and uninstall behaviour. It is a general reference, not approval of a specific package.
