Authoritative reference for the 18 WordPress.org Plugin Directory guidelines. Covers GPL licensing, plugin naming/trademark rules, trialware restrictions, and all other submission requirements.
Use this skill when you need to:
Scope the review to the request. Conceptual licensing or naming questions do not require a WordPress installation or a full audit.
Use official Plugin Check documentation for tool behavior and the directory guidelines for policy. Surface unresolved policy ambiguity, uncertain findings, and fixes outside the authorized scope for human review.
Use the detailed, per-guideline checklist in guideline-review-checklist.md. Load this reference file only when a full guideline audit is requested.
Use gpl-compliance.md for full license tables, compatibility nuances, and examples. Keep this inline section as a quick decision aid.
License: and License URI: values from the examples below. Link to gpl-compliance.md for the compatibility basis; do not merely say to add a matching URI.License: header and License URI: in the main plugin file.| Version | Year | Key Addition |
|---|---|---|
| GPLv1 | 1989 | Base copyleft: share-alike for modifications |
| GPLv2 | 1991 | "Liberty or death" clause (Section 7), clearer distribution terms |
| GPLv3 | 2007 | Anti-tivoization, explicit patent grants, compatibility provisions |
WordPress uses GPLv2 or later, meaning plugins can use GPLv2, GPLv3, or "GPLv2 or later".
