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.
