In sight of the recent increase long-lasting tend in low quality plugins that would provide unfavourable plugin intercompatibility, the following guidelines (Plugin Quality Requirement Standards, PQRS) are provided to developers as standards when developing plugins. This post uses key words in RFC 2119 and RFC 6919 to indicate requirement levels. === MIGRATED: See the file at https://github.com/poggit/support/blob/master/pqrs.md instead. === Should anything be added, removed or amended, feel free to reply below. The above standards will be brought into consideration in Poggit plugin reviewing.
