skills

Write tests, mock functions, assert values, and configure test suites for Roblox/Luau code using Jest Roblox — a Luau port whose API diverges from JS Jest in subtle, non-obvious ways that LLM training data does not cover. Use whenever encountering Jest in Roblox/Luau code: editing .spec test files, calling jest.fn/jest.mock/spyOn, using describe/it/expect, or debugging Jest tests.

Test-driven development (TDD) with red-green-refactor loop. Use when user wants to build features, fix bugs, mentions "tdd", wants integration tests, or implementing all new code.

Opinionated preferences for roblox-ts development. Use when setting up new roblox-ts projects or when coding style/tooling decisions arise.

Use when creating new skills, editing existing skills, or verifying skills work before deployment
