How does it help identify architectural issues?

The skill includes a reference for common anti-patterns like God Objects, N+1 queries, and Circular Dependencies, providing clear solutions and refactoring strategies for each.

Does this skill support C4 diagramming?

Yes, it includes templates for Level 1 (System Context), Level 2 (Container), and Level 3 (Component) diagrams, supporting both ASCII and Mermaid formats for technical documentation.

Can I use this to document technical decisions?

Absolutely. The skill provides standardized templates for Architecture Decision Records (ADRs) to help teams document the context, status, and consequences of significant technical choices.

What is the PACT Architecture Patterns skill?

It is a specialized capability for Claude Code that provides architectural design patterns, C4 diagram templates, and best practices to guide the software system design process.

Does it help with API design?

Yes, it offers guidance on RESTful resource naming, pagination strategies (cursor vs. offset), and consistent error response formats to ensure high-quality API development.

API Development

Guides system design using C4 diagram templates, SOLID principles, and standardized architectural patterns for robust software development.

About

PACT Architecture Patterns is a specialized Claude Code skill designed to streamline the architectural phase of software development. It provides developers with a comprehensive framework for designing systems, offering C4 model templates for clear visualization, quick references for SOLID principles, and proven design patterns for APIs and data access. Whether you are defining component boundaries, documenting technical decisions through ADRs, or auditing for common anti-patterns, this skill ensures your system architecture is scalable, maintainable, and well-documented directly within the Claude Code environment.

Key Features

Integration and data access patterns like Repository and Service Layer implementations.
Standardized API design patterns including resource naming, pagination, and error formatting.
Pre-configured Architecture Decision Record (ADR) templates for decision tracking.
C4 Model templates for System Context, Container, and Component levels.
SOLID principles reference and detection signs for architectural violations.
40 GitHub stars

Use Cases

Standardizing API contracts and internal component communication patterns across a development team.
Conducting architectural reviews and refactoring sessions to eliminate technical debt and anti-patterns.
Designing and documenting high-level system architecture for new microservices or monoliths.
