What it does

In the author's own words, from each skill's SKILL.md.

  • typescript-discriminated-unions

    Apply, review, and explain discriminated unions in TypeScript. Use automatically for tasks involving mutually exclusive variants, invalid state prevention, exhaustiveness checking, variant-specific object properties, application state, function arguments, or React props.

    skills/typescript-discriminated-unions/SKILL.md on GitHub (opens in a new tab)

  • typescript-functions

    Apply, review, and explain TypeScript function conventions. Use automatically for tasks involving function responsibility, statelessness, purity, side effects, function arguments, function API design, or return types.

    skills/typescript-functions/SKILL.md on GitHub (opens in a new tab)

  • typescript-naming

    Apply, review, and explain TypeScript naming conventions. Use automatically for tasks involving exports, identifiers, generic type parameters, acronyms, React props and handlers, hooks, comments, or TSDoc.

    skills/typescript-naming/SKILL.md on GitHub (opens in a new tab)

  • typescript-react

    Apply, review, and explain React conventions from the TypeScript Style Guide. Use automatically for TypeScript and TSX tasks involving prop-derived state, prop typing, component responsibilities, data flow, compound components, or client and server state.

  • typescript-source-organization

    Apply, review, and explain TypeScript source organization conventions. Use automatically for tasks involving feature-based organization, code colocation, import paths, import sorting, monorepos, or frontend and backend project structure.

    skills/typescript-source-organization/SKILL.md on GitHub (opens in a new tab)

  • typescript-style-guide

    Apply, review, and explain the opinionated conventions in the TypeScript Style Guide. Use automatically only when TypeScript conventions are part of the requested task, including type modelling, discriminated unions, function APIs, variables and state, naming, source organization, React props, component APIs, state management, data flow, or tests. Do not use for styling or layout alone.

  • typescript-tests

    Apply, review, and explain testing conventions from the TypeScript Style Guide. Use automatically for TypeScript and TSX test tasks involving test design, AAA, mocking, isolation, black-box testing, Testing Library queries, test descriptions, or snapshots.

  • typescript-types

    Apply, review, and explain TypeScript type conventions. Use automatically for tasks involving inference, readonly data, type-safe constants, template literal types, any and unknown, assertions, type errors, type definitions, arrays, type imports, or generated service types.

    skills/typescript-types/SKILL.md on GitHub (opens in a new tab)

  • typescript-variables

    Apply, review, and explain TypeScript variable conventions. Use automatically for tasks involving variable declarations, const assertions, enum alternatives, literal-union state modelling, boolean flags, or choosing between null and undefined.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
