Schema Validation with Zod v4
Development
A TypeScript-first schema validation library that infers static types from schemas and validates data at runtime. Use it to enforce data integrity, parse external inputs safely, and reduce boilerplate in TypeScript projects.
Interactive Planning Agent
Development
Interactive planning agent. Designs verification specs through Q&A with the human and hands off to the orchestrator for execution. Use it when you need to break down a complex task into manageable specs after clarifying requirements.
Simple Task Implementation
Development
Implements small features, bug fixes, or quick enhancements using best practices from the project's steering documents. Uses test-driven development (Red-Green-Refactor), SOLID principles, and security checks. Ideal for tasks where the full SDD workflow is unnecessary.
Unity Lighting & Post-Processing Specialist
Development
Specialist in Unity lighting and post-processing for atmosphere, mood, and visual polish. Covers URP and HDRP Volume systems, including light types (directional, point, spot, area) and post-processing effects (bloom, color grading, vignette, DOF, motion blur, ambient occlusion, SSR). Use this skill when setting up scene lighting, adding visual polish, creating mood, optimizing performance, or baking lightmaps.
Draft Post Writer
Content
This skill guides users through a structured process to create blog post drafts for Substack and LinkedIn. It asks questions to gather content, then produces a polished Substack post (250-500 words) and a LinkedIn summary (100-150 words). Use it when you want to quickly turn your work into shareable posts without spending hours writing.
Codebase Knowledge Base Initialization
Development
Initializes a .codebase knowledge base that provides AI agents with project-level understanding. Use for first-time setup, rebuilding from scratch, or when the user requests /codebase-init. Scans project structure, generates an INDEX.md and modular documentation files.
Simple PR Creation
DevOps
Create a PR automatically from staged changes with auto-generated commit message. Verifies workspace state, updates main, and creates a descriptive branch name.
Design System Analysis
Development
Analyzes theme-aware design systems by extracting CSS variables (tokens) from globals.css, mapping mock color values to theme tokens using OKLCH similarity, and identifying gaps between mocks and existing tokens. Useful when working with NextSpark themes that have different light/dark mode token sets and need to convert design specs to theme-compatible code.
UI/UX Design Specifications
Design & Creativity
Create comprehensive UI/UX design specifications including component specs (Atom/Molecule/Organism), WCAG 2.1 AA accessibility audits, design tokens, responsive behavior, and developer handoffs.
Documentation-First PRD Creation
Documentation
Helps create Product Requirements Documents (PRDs) with a documentation-first approach, starting with a GitHub issue and generating a detailed PRD file. Focuses on milestone-based planning and user-facing content to guide development.
Backend Queries
Development
Provides guidelines for writing secure and optimized database queries using parameterized queries, eager loading, proper indexing, transaction management, and result caching. Helps when implementing filtering, sorting, pagination, or resolving N+1 query problems in controllers, services, or repositories.
Add Game Subsystem
Development
Scaffolds a complete new game subsystem end-to-end: models, service, router, schemas, migrations, OpenAPI spec, and tests. Use this skill when adding a major new game feature that spans multiple layers (database, service, API, tests), such as a crafting system, an auction house, a reputation system, or a quest system.
