For this kinda of check, I recommend the http://jsonlint.com/ site. You just copy your text there, and it will point errors like extra commas, wrong opening brackets, etc…

Then I must have dislexia as well 
I constantly miss stuff like that in my files (especially in the en.json).
But a good place to check your JSON files is JSONLint . There, no comma can slip through…
Oh… @BrunoSupremo just slipped past me and inserted his post. Smooth move, man

To be fair, Stonehearth’s JSON parser is beyond bad and its error messages, if there even are any, aren’t helpful at all.
allright next question 
so i iam thinking of making a new job. Can you guys help me by telling me what i am still missing and these few code lines i cant figure out.
So what i found i need in the mod for a new job are these files:
entities/(every other entity i need to make)
jobs/painter/painter_abilities
jobs/painter/painter_outfit
jobs/painter/painter_(tool)
jobs/painter/painter_workbench
jobs/painter/images
jobs/painter/recipes
jobs/painter/skin
jobs/painter/painter.lua
jobs/painter/painter_descritpion.json
jobs/index.json
locales/en.josn
manifest.json
Those are the files i see i need for a new job.
Aside from that i cant find the source of these lines to changes. i take carpenter as example.
“controller”: “stonehearth:class:carpenter”, (does this refer to the class you created in the .lua?)
“talisman_uri”: “stonehearth:carpenter:talisman”,
“promotion_activity_name”: “promote_carpenter”,
do i have erverything? and those 3 lines can someone explain them to me. all the other stuff i got except for those.
I also know how to created items and how recipes work and stuff so that is no problem. i have spit trough all the files in the maps i listed and understood where they for where and how they worked.
tanks in advance!
