Design

TypeScript monorepo patterns including contract-port architecture, dependency injection, hermetic primitive ports, and composition root. Use when creating packages, designing contracts/interfaces, implementing ports, wrapping platform primitives (Date, console, process), or testing with inline mocks.

Open source community building and engagement. Welcoming contributors,managing discussions, writing release notes, and fostering a healthyproject ecosystem.

Automatically guides users through RED-to-GREEN TDD workflow when implementing features in kiro projects

Reviews React components and provides improvement suggestions. Use when you need code review, component review, structure improvement, refactoring, or component separation.

Idiomatic Go 1.25+ development. Use when writing Go code, designing APIs, discussing Go patterns, or reviewing Go implementations. Emphasizes stdlib, concrete types, simple error handling, and minimal dependencies.

Automate Ideal Direct finance and supply chain SOPs with browser-based workflow guidance. Handles payroll, working hours, purchase orders, and audits using Playwright MCP.

Advanced patterns for Hono-based Electron IPC including CQRS, Zod validation, error handling, and reactive data with RxJS. Use when implementing complex IPC patterns or needing guidance on architecture decisions.

Create clean, single-file HTML pages for displaying information. Use for quick reference pages, comparisons, lists, or any data you want to view in a browser.

Builds APIs with Express including routing, middleware, error handling, and security. Use when creating Node.js APIs, building REST services, or adding middleware-based server functionality.

Create distinctive, memorable UI for landing pages, portfolios, marketing sites, and one-off creative work. Use when the user explicitly wants something "distinctive", "creative", "memorable", or "unique" - NOT for standard app components where consistency matters.

Write tests following 3-layer pyramid (unit 95%, integration 85%, E2E critical paths) with 1:1 file mapping for unit tests. Covers test organization, coverage requirements, fixtures, and best practices. Use when writing tests, checking coverage, or validating test structure.

Creates well-formed tasks following a template that engineers can implement. Use when creating tasks, defining work items, creating tasks from PRD, breaking down features, or converting requirements into actionable tasks.

Design phase with validation gates. Annotates PRD, creates story outlines, builds execution plan (via execution-plan-creation skill), validates artifacts via reviewer. NO HITL in this phase - single HITL happens after all docs complete.

PolicyEngine visual identity - colors, fonts, logos, and branding for web apps, calculators, charts, and research

Write consistent, maintainable CSS following the project's methodology (Tailwind utility classes) while minimizing custom CSS and adhering to design system tokens. Use this skill when writing or editing CSS files, Tailwind classes in React components (.tsx, .jsx files), when implementing design system colors/spacing/typography, when using Tailwind utility classes, when deciding between framework utilities vs. custom CSS, when optimizing CSS for production with tree-shaking, when configuring Tailwind theme extensions, or when maintaining design consistency across the application.

Build interactive CLI questionnaires with validation, conditional logic, parameter mapping, and review capabilities using the question-and-answer library

Create distinctive, production-grade frontend interfaces with high design quality. Specialized in Svelte/SvelteKit applications with full-stack capabilities. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Use when implementing new features in Quetrex. Ensures TDD, TypeScript strict mode, Next.js App Router patterns, ShadCN UI components, and security best practices are followed. Updated for November 2025 standards.

Create a git commit with a short message (up to 50 characters). Use when the user asks to commit changes with a short/concise message.
