rate.yml

Controls the maintenance difficulty scoring coefficients. The difficulty is computed and cached in data/mods.db:

Codacy base score = Codacy score (0 is treated as 0.1)

Architecture coefficient = Σ(values matched in rate.yml) ÷ total declared architectures
Version bonus (per MC version) = loader multiplier × (Σ status values across that version's loaders ÷ loader count)
                                loader multiplier: 1 loader = 1; multiple loaders = multi_loader_multiplier
Version coefficient = 1 + Σ(version bonus across all MC versions)

Final difficulty = (Codacy base score + Architecture coefficient) × Version coefficient

Field Reference

version

Bonus per support status, applied per MC version × loader combination.

Status	Default	Meaning
All	0.075	Fully supported
Partly	0.05	Partial support
BugFix	0.025	Bug fixes only
Planned	0.04	Planned but not released

architecture

Coefficient per architecture. If a mod declares several architectures, the coefficients of those found in rate.yml are summed and divided by the total number of declared architectures (unmatched entries count as 0).

Architecture	Default	Description
Fabric-Loom	0.5	Standard Fabric build
ModDevGradle	0.5	Standard NeoForge build
Architectury-Loom	2	Multi-platform build (higher complexity)
Stonecutter	0.8	Multi-version build tool

multi_loader_multiplier

Multiplier used when a single MC version supports more than one loader. Default 1.2.

Calculation Example

A mod with:

• Codacy score: 1.5
• One architecture: Architectury-Loom (coefficient 2.0 → architecture coefficient = 2.0)
• One MC version supporting 3 loaders, all marked All

Version bonus for that version:

• status total = 0.075 × 3 = 0.225
• ÷ 3 loaders = 0.075
• × multi_loader_multiplier 1.2 = 0.09

Final difficulty:

(1.5 + 2.0) × (1 + 0.09) = 3.5 × 1.09 ≈ 3.8
