1. Software Development

Generates and enhances unit and integration tests for backend and frontend code, ensuring robustness and reliability in software development.

Provides a practical guide for creating reusable React components with props typing, stateless design, clsx usage, and export conventions.

Creates Playwright snapshots to validate UI component visual consistency and detect regressions, ensuring reliable updates and accessibility compliance.

Guides monorepo component styling with Vanilla Extract, token management, and variant class best practices for consistent UI development.

Generates and modifies bash argument parsers for command-line tools, handling positional arguments, flags, and options.

Provides utilities for argument parsing, project scaffolding, documentation generation, and command-line completion scripts.

Generates Jest unit, integration, and React Testing Library component tests with mocks and edge case coverage for TypeScript projects.

Builds Next.js and React components, pages, and layouts using App Router, RSC, Tailwind CSS, and accessibility standards.

Generates boilerplate templates for Next.js, React, NestJS, and common project patterns to accelerate development.

Automates creation of new Go projects in monorepo, generating main.go, README, and AGENTS.md for CLI tools or libraries.

Assists in high-level system architecture planning with component diagrams, scalability analysis, and technology trade-offs for technical specifications.

Scaffolds NestJS backend code for modules, controllers, services, DTOs, REST/GraphQL APIs, and WebSocket handlers with Jest tests.

Designs efficient database schemas for PostgreSQL, MongoDB, and Redis with entities, relationships, indexes, constraints, and backward-compatible schema evolution.

Provides a systematic methodology for efficiently understanding large codebases, enabling safe modifications, debugging, and onboarding.

Automates rebuilding production build (dist) folder for GitHub PRs, especially dependency update PRs.

Provides comprehensive tools for developing Minecraft Fabric mods, including porting from Forge/NeoForge and MCP integration for decompilation and mixin validation.

Enforces Test-Driven Development for all code changes, ensuring test coverage and quality through pre-written tests.

Enables behavior-driven UI testing for front-end applications using framework-agnostic DOM Testing Library patterns.

Enforces TypeScript strict mode patterns for robust type safety and code quality in any TypeScript project.

Enables debugging, prototyping, and exploratory API investigation for solution spiking before formal TDD implementation.

Assesses code for refactoring opportunities after tests pass, improving structure without altering behavior.

Enables writing logic and data transformations using functional programming patterns with immutable data.

Provides behavior-driven testing patterns and test factory utilities for efficient test development.

Provides TypeScript best practices for backend services, API handlers, and shared utilities with async/await, typed errors, and strict type safety.
