custom badge rule file questions

I am creating some custom badges, and don't know how to create the rule for "extension","command" and "frequency" for below use cases:

1. assign badge when an user created over 30 easyblog articles in blog category A.
2. assign badge when an user answer over 30 easydiscuss questions.
3. assign badge when an user answer over 30 easydiscuss questions in category A.
4. assign badge when an user upload over 300 photos to easysocial
5. assign badge when an user submit over 30 reviews to jreview listings.

    {

        // The title of the badge.

        "title"         : "Badge Title",



        // The description of the badge

        "description"   : "Some description of your badge",



        // The steps needed to unlock this badge.

        "howto"         : "To unlock this badge, you need to do something.",



        // The alias of the badge.

        "alias"         : "socializer",



        // The extension for this badge.

        "extension"     : "com_easysocial",



        // The badge command.

        "command"       : "conversation.create",



        // The default avatar for this rule. Relative to the site's document root a.k.a (JPATH_ROOT)

        "avatar"        : "media/com_easysocial/badges/socializer.png",



        // When user creates a new discussion for 15 times.

        "frequency"     : 15

    }
