Starfield Toolkit

A Windows GUI for managing Bethesda Creations — load order, updates, rule books, and Fast Lane compatibility, without ever touching your game files.

Get started How Auto-Sort works

Concepts

Short articles explaining how the toolkit works under the hood — the auto-sort pipeline, what a rule book is, why the caching is the shape it is. Read these if a feature surprises you and you want to understand the logic, or if you're contributing to the codebase.

Auto-Sort overview →

End-to-end: from pressing the button to writing Plugins.txt.

Sorter priority →

TES4 > Rule Books > LOOT > Categories, and why.

TES4 masters →

Parsing plugin headers and what a MAST subrecord means.

LOOT masterlist →

Fetching the community YAML and its group model.

Category tiers →

The 11-tier community system, refined for Fast Lane checks.

Rule books →

File format, precedence, curated vs user, how they round-trip through the editor.

Constraints solver →

Merging constraints from multiple sorters and topologically sorting the graph.

API caching →

Immutable vs volatile fields, staleness windows, disk layout.

Description parser →

Using an LLM to extract load-order hints from creation descriptions.

Fast Lane baseline →

How the April-2026 snapshot is built and used.
