Expert guidance for designing production-grade Zod schemas with TypeScript type inference, schema composition, error handling, and full-stack integration patterns.

A meta-skill that makes AI coding assistants think strategically before acting. Implements a 5-factor risk heuristic (Reversibility, Blast Radius, Coupling, Stakes, Uncertainty) to determine whether a code change needs shallow execution, medium analysis, or deep pre-mortem reasoning. Based on cognitive science, game theory, and software engineering economics research.

A generalist skill that helps users interact with AI safely across all sensitive domains. Covers health, finance, legal, mental health, nutrition, parenting, relationships, and general AI literacy. Teaches critical evaluation of AI outputs, recognizes when professional help is needed, and prevents over-reliance on AI for consequential decisions.

Comprehensive prompt engineering guidance covering techniques (chain-of-thought, few-shot, system prompts), evaluation, guardrails, structured output, and building reliable AI interactions.

Expert guide for creating pixel art as a structured design system. Covers grid logic, palette constraints, sprite architecture, tile standards, animation rules, engine integration (Unity/Godot), scaling best practices, and production pipeline from Aseprite to deployment.

Identifies code smells and applies systematic refactoring patterns from Martin Fowler's catalog. Guides safe refactoring with test coverage, legacy code strategies, and incremental improvement plans that preserve behavior while improving design.

Builds WCAG 2.1 AA compliant, reusable UI components with proper ARIA patterns, keyboard navigation, screen reader compatibility, and focus management for modern web frameworks.

Systematically removes LLM fingerprints from text using evidence-based linguistic research. Replaces machine patterns (vocabulary, structure, tone) with human writing characteristics while preserving meaning and quality.

Design, author, and maintain operational runbooks that enable on-call engineers to diagnose and resolve incidents faster with structured response procedures, escalation frameworks, and toil reduction strategies.

Helps users understand the narrow safe zone for AI in mental health contexts, recognize dangerous interaction patterns, identify parasocial relationship risks, and know when AI support crosses into territory that requires a human professional.
