About
Primal Skies is a skyblock modpack built around PrimalCore, with an alternate early-game approach to gathering materials, food, and resources that avoids the usual need to sift for or explode materials. Progression moves from primitive resource gathering into automated collection and improved refining, then opens up planetary exploration through Galacticraft. The pack’s progression draws on PrimalCore, Better With Mods, Botania, and Kitsu’s Forgecraft, while Foundry introduces technology and Rockhounding Mod: Chemistry lets players create ores and alloys. Silent’s Gems supports protection and weapon-making, and Chisel, Blockcraftery, and Chisels & Bits provide blocks and tools for designing and decorating an island. A Better Questing guide helps orient players, with opening goals that include obtaining flint, magically obtaining a spruce sapling, and crafting a Flint Work Blade.

No harmful code found in the mods we checked
We checked 82 of its 84 mods and the files in the pack itself, without running them.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
How we checked
- Its projects84 mods
- Not checked yet2 mods
- Files in the pack itself116 settings files, 11 scripts, 13 other files, 3 mod jars.
Privacy
3 mods send something about you
We read the code of 82 of its 84 mods, without running it.
Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.7 mods
- Send nothingTheir code contacts no web address.72 mods
- Not read yetWe have not read their code yet.2 mods
AI
AI used in 5 of the 44 mods we checked
We found an AI tool in them, or their authors declared AI content.
40 mods are not checked yet.
No sign so far that AI was used to make the pack itself
We looked for AI tools in its texts and found none.
We have not read its files and images yet.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
