I evaluate it the same way that I evaluate any other code that I&#x27;m bringing into our project: is it robust, extensible, free of obvious errors, covered by comprehensive unit&#x2F;functional tests, etc.<p>I would say that &quot;project is open 6 months&quot; is a pretty poor metric, because 6 months is a <i>lot</i> longer than the handful of days that your custom code will have existed when you add it instead.
