Crafting skills gate access to manufacturing recipes. Without a high enough level, players cannot use the corresponding recipes even if they have all the required materials. Use "category": "crafting" in the skill meta.

How Crafting Skills Unlock Recipes

A recipe references a crafting skill and minimum level in its requires field:

"requires": { "stellar_forge:forging": 4 }

The player must reach Forging level 4 before they can use this recipe. Skill levels form a natural progression ladder:

Level 0    →  Basic recipes (copper, iron)
Level 1–3  →  Common ingots
Level 4–6  →  Advanced ingots, basic alloys
Level 7–9  →  Exotic materials, complex alloys
Level 10   →  Endgame crafting

Standard Crafting Skill Types

Example — Forging

{
  "skills": {
    "id": "stellar_forge:forging",
    "displayName": "skills.category.stellar_forge.crafting.forging",
    "description": "skills.category.stellar_forge.crafting.forging.desc",
    "meta": {
      "category": "crafting",
      "topLevel": 10,
      "math": { "start": 500, "progressionCurve": 1.7 }
    }
  }
}

The foundational crafting skill. Unlocks smelting recipes. Every player will need a few levels in this to progress.

Example — Alloying

{
  "skills": {
    "id": "stellar_forge:alloying",
    "displayName": "skills.category.stellar_forge.crafting.alloying",
    "description": "skills.category.stellar_forge.crafting.alloying.desc",
    "meta": {
      "category": "crafting",
      "topLevel": 10,
      "math": { "start": 500, "progressionCurve": 1.7 }
    }
  }
}

The advanced crafting tier. Lets players combine refined ingots into composite materials for high-tier equipment.
