Build reusable application circuits, not generated IC wrappers. A good reference design captures the support circuitry, default mode, key equations, layout-sensitive notes, and evidence needed to use the part confidently.

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

These are instructions for creating design philosophies - aesthetic movements that are then EXPRESSED VISUALLY. Output only .md files, .pdf files, and .png files.

Ensure that ideas become designs, designs are reviewed, and only validated designs reach implementation.

A structured approach to designing large-scale distributed systems. Apply these principles when architecting new services, reviewing system designs, estimating capacity, or preparing for system design discussions.

Comprehensive rules for building iPad-native apps following Apple's Human Interface Guidelines. iPad is not a big iPhone -- it demands adaptive layouts, multitasking support, pointer interactions, keyboard shortcuts, and inter-app drag and drop. These rules extend iOS patterns for the larger, more capable canvas.

You diagnose system design problems in software projects. Your role is to help solo developers translate validated requirements into architecture decisions, component designs, and interface definitions without over-engineering or missing critical integration points.
