Hi all, I have an idea for my first mod for Stellaris and I don't know where to start. I am hoping y'all could give me some pointers to make the mod.

The Idea behind the mod is a technology that unlocks a planetary decision to increase the habitability of that planet but also increases building cost, time and upkeep on said planet. It would be a repeatable decision up to 5 times (maybe more) and each time you take the decision the planets habitability would increase by 10% but so would the building cost, time and upkeep. ie at Level 5 the planet would have +50% habitability but also +50% Building cost, time and upkeep.
The Technology would be early on in the game, able to be researched around or slightly before Terraforming and called something like Xeno-Adaptive Architecture

Habitability mod for Stellaris. - Xeno-Adaptive Architecture -
Planetary decision taken after planet is colonized (or before if possible*)
Unlocked via technology early in the game, around the same time as Terraforming**
5 levels (ie Repeatable 5 times)
  • Level 1 Cost 250 mineral 250 Alloys
Increase Habitability +10%
Building Cost +10%
Building upkeep +10%
Building Time +10%
  • Level 2 Cost 250 mineral 250 Alloys
Increase Habitability +10% (20%)
Building Cost +10% (20%)
Building upkeep +10% (20%)
Building Time +10% (20%)

  • Level 3 Cost 250 mineral 250 Alloys
Increase Habitability +10% (30%)
Building Cost +10% (30%)
Building upkeep +10% (30%)
Building Time +10% (30%)

  • Level 4 Cost 250 mineral 250 Alloys
Increase Habitability +10% (40%)
Building Cost +10% (40%)
Building upkeep +10% (40%)
Building Time +10% (40%)

  • Level 5 Cost 250 mineral 250 Alloys
Increase Habitability +10% (50%)
Building Cost +10% (50%)
Building upkeep +10% (50%)
Building Time +10% (50%)

  • I know that Delve into the secrets of the yhut has a similar effect, adding +10 Habitability for Devastation.
  • Terraforming the planet into a Gaia world or Ecumenopolis world would remove the habitability and cost bonuses if possible
*If a decision can be taken before the planet is colonized I think it would be cool to add increased colonization time scaling with the level of decision taken.
**if possible taking this technology will make Terraforming show up less often as species now doesn’t need it to colonize planets
There is also the idea that it could also just be a technology that unlocks an edict increasing habitability across the board by 50% while also increasing Building Cost, Time, and Upkeep. however this is a bit to broad stroke in my opinion.
 
The bid/boost bid for Galactic Market Nomination decision could help you with the repeating factor.
For removing the modifier when a planet is terraformed, putting a check for the equivalent on_action should work.
