Use when designing components, systems, or entity structures for jecs in Roblox. Use when deciding if data should be one component or multiple, when archetype transitions seem expensive, or when choosing entity members vs relationships.

Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive "Signs of AI writing" guide.

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

Use when building ECS-based games in Roblox with roblox-ts using jecs for entities, components, queries, and relationships

Testing Roblox/Luau code with Jest Roblox. Use when writing tests, mocking functions, asserting values, or configuring test suites in Luau with Jest Roblox. NOT JavaScript Jest — uses .never instead of .not, jest.fn() returns two values, 0 is truthy.

Node.js package manager with strict dependency resolution. Use when running pnpm specific commands, configuring workspaces, or managing dependencies with catalogs, patches, or overrides.

Use when writing TypeScript code for Roblox using roblox-ts, especially when unsure if a JavaScript API exists or how to handle Luau interop

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.

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