name: latitude-biome-authority
description: >
Authoritative list of all vanilla Minecraft biomes and the latitude bands
they are allowed to generate in for the Latitude (Globe) mod. This skill
forbids guessing, omission, or reassignment of biomes and serves as the
single source of truth for biome inclusion and climate eligibility.
Latitude Biome Authority — Vanilla Minecraft (Java 1.21.11)
Generated: 2026-01-31
RULES (MANDATORY)
- Every vanilla biome listed here must exist in at least one valid generation path.
- Windsurf must never invent, remove, or reassign biomes outside this table.
- If a biome is missing in-world, the cause is tag omission or logic error, not intentional rarity.
- Latitude bands are authoritative; variants and overlays are secondary.
- Rarity is a design knob, not a probability guarantee.
- Caves, rivers, oceans, Nether, and End biomes are not latitude-decided unless explicitly stated.
- Mountain / peak biomes are overlays and may restrict placement but must not override latitude truth.
Latitude Bands
- Equator — hottest + wettest
- Tropics — hot + wet-ish
- Arid — hot + dry
- Temperate — mild
- Subpolar — cold
- Polar — coldest
Overlay: Mountain / Peaks
Only allowed when “mountainness” is true (height, slope, or climate params), regardless of latitude.
