Architectural patterns solve specific structural problems. This skill provides a decision framework for when to apply each pattern, not a catalog to memorize.

Core principles and preferences for code style, documentation, and development workflow.

Use this skill to design, implement, and review secure blockchain systems: smart contracts, on-chain/off-chain integration, custody and signing, testing, audits, and production operations.

Design intuitive, accessible, user-centered interfaces.

Use this skill for system-level design decisions rather than implementation details within a single service or component.

A practical framework for managing the fundamental challenge of software engineering: complexity. Apply these principles when designing modules, reviewing APIs, refactoring code, or advising on architecture decisions. The central thesis is that complexity is the root cause of most software problems, and managing it requires deliberate, strategic thinking at every level of design.

This skill provides guidance for quality focused software development and architecture. It is based on Clean Architecture and Domain Driven Design principles.
