iOS Simulator automation and interaction using the AXe CLI tool. Use when working with iOS simulators for UI automation, testing, accessibility verification, or screen recording. Specific use cases include simulating touches and gestures (tap, swipe), entering text, pressing hardware buttons (home, lock, Siri), recording or streaming simulator video, extracting UI accessibility information, or automating iOS simulator interactions. Assumes axe CLI is already installed.

UI/UX enhancement workflow for visual hierarchy, spacing, typography, and responsive layout. Use when refining page layout, polishing components, or improving readability and responsiveness in web UI work.

Transform messy code into clean code through disciplined refactoring. Code smells, refactoring patterns, and the courage to improve without breaking. Leave every codebase better than you found it.

Orchestrate complete or partial feature implementation workflow with configurable phases. This skill should be used to run the full workflow (specification → research → plan → implement → test → fix) or specific phases, coordinating between all feature-implementation skills automatically.

Design reusable prompt templates that encode domain-specific patterns for recurring AI development tasks.Use this skill when you've executed similar prompts 2+ times and need to capture the pattern as reusableintelligence. Transforms one-off prompts into parameterized templates that maintain quality while reducingcognitive load. Helps students move from Layer 2 (AI Collaboration) to Layer 3 (Intelligence Design) inthe 4-Layer Teaching Method.
