Use when adding or fixing Luau type annotations: generics, unions, narrowing, strict mode, sealed tables, module type exports, typed metatables.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Luau Type System ## When to Load Load for Luau annotations, inference, narrowing, strictness, exports, and solver features. Syntax: `roblox-luau-core`; lifecycle/scheduling: `roblox-luau-patterns`. ## Quick Reference **Strictness:** `--!strict` for maintained code, `--!nonstrict` while transitioning, `--!nocheck` only for legacy or generated code. Directives and project settings select the mode; never assume one global default. **New solver gate:** `keyof`, `rawkeyof`, `setmetatable<T, M>`, `type function`s, and `read` members need the new type solver. On by default for `nocheck`/`nonstrict` projects; strict projects need `Workspace.UseNewLuauTypeSolver = Enabled` (Scripting). Errors here usually mean wrong solver, not wrong syntax. **Inference philosophy:** Infer first; annotate boundaries (params, returns, exports). Don't annotate every local. **Sealed vs unsealed tables:** An unannotated local table stays open to new fields until annotated, returned from a function, or its scope exits; annotation seals it. Build tables fully before annotating; passing a table to a typed function does not seal it. …

How to install
mdr add tabooharmony/roblox-brain/roblox-luau-types@sha256:547e852a7773b0dbThe line at the top of this page pins the label git:20261015.62bdabd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
