Can this skill help with frontend and backend alignment?

Yes, its Coherence dimension specifically checks if types are consistent across the stack and if API changes will break existing clients.

What are the five dimensions covered by this skill?

The skill interrogates Scale, Data, Security, UX Impact, and Coherence to ensure comprehensive architectural coverage and prevent missed requirements.

When should I use the System Design Interrogation skill?

It is best used during the planning or brainstorming phase, specifically before any code is written, to identify trade-offs and prevent costly rework.

How does this skill improve application security?

It forces evaluation of tenant isolation, authorization failure states, and PII handling, ensuring security is baked into the design rather than added as an afterthought.

Is this skill part of a larger toolkit?

Yes, it is part of the SkillForge toolkit and is designed to integrate with brainstorming, architecture decision records, and verification workflows.

Productivity & Workflow

Guides architectural planning through structured questioning to ensure scalability, security, and coherence before implementation.

About

System Design Interrogation is a specialized Claude Code skill designed to eliminate architectural debt before it starts. By guiding developers through a systematic 'Question Before Implementing' workflow, it evaluates five critical dimensions: Scale, Data, Security, UX Impact, and Coherence. This tool prevents common pitfalls like late-stage scalability issues, security vulnerabilities in tenant isolation, and frontend-backend contract mismatches, ensuring every feature is production-ready and built on a solid architectural foundation.
