SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams avoid tangled architectures by providing technology-agnostic guidance for designing modular systems with clear ownership, boundaries, and communication paths.

Core Features & Use Cases

Module Boundary Design: Define cohesive bounded contexts, public contracts, ownership rules, and isolation strategies for new or existing systems.
Architecture Reviews: Identify coupling issues, persistence leaks, unclear dependencies, and failure containment gaps during modularity assessments.
Use Case: When reviewing a growing backend, use this Skill to evaluate whether services, packages, or domains should be split, merged, or redesigned around explicit contracts.

Quick Start

Ask the skill to review my system architecture and suggest improvements to module boundaries, ownership, and dependencies.

FAQPage Schema

How do I design clear bounded contexts and service boundaries for a growing backend?▼

Design clear service boundaries by analyzing module cohesion, ownership rules, and explicit contracts between components. This approach isolates state, defines bounded contexts, and ensures resilient module structures for growing backends without tangling dependencies.

What is the best way to review software architecture for coupling and dependency issues?▼

Review software architecture for coupling issues by assessing persistence leaks, unclear dependencies, and failure containment gaps. This technology-agnostic analysis identifies whether services, packages, or domains should be split, merged, or redesigned around explicit contracts.

How do I assess if software modules should be split or merged during an architecture review?▼

Assess module splitting or merging by evaluating dependency structures, state isolation, and ownership boundaries. This analysis provides principles for explicit contracts and scalable module structures to determine optimal service decomposition and package organization.

When do I need explicit contracts and state isolation for software design?▼

You need explicit contracts and state isolation when designing modular systems requires clear communication paths and failure containment. This prevents tangled architectures by ensuring technology-agnostic boundaries and resilient ownership rules between components.

Can I use this modular design approach for package organization and service decomposition?▼

This modular design approach applies directly to package organization and service decomposition by defining cohesive bounded contexts, public contracts, and isolation strategies. It evaluates module boundaries, ownership, and dependencies for new or existing systems.

Why does my system architecture have tangled dependencies and unclear ownership?▼

Tangled dependencies and unclear ownership arise from lacking explicit module boundaries, public contracts, and state isolation. Applying modular design principles analyzes these boundaries and communication paths to resolve persistence leaks and failure containment gaps.
