Overview

Architecture Design (Grade A) is a security-tested data-ai skill for Claude AI that helps design or evaluate system architecture, including service boundaries, data models, API contracts, infrastructure topology, and database selection. It's used for designing systems, evaluating architecture decisions, and creating architecture diagrams. The tool guides users through gathering requirements, running architecture assessments, selecting architecture patterns, and designing data models and API contracts. It's suitable for startup founders and technical teams looking to plan and document their system architecture.

Q&A

What input is required from the user to start an architecture assessment?

Users must supply startup context details like product description, tech stack, current state, expected scale (users, requests/sec, data volume), team size, budget, and any hard constraints. If information is missing, the tool will prompt for it.

Asked by Emiliano Vargas · Jan 22, 2026

Does the tool provide guidance on choosing between monolith, modular monolith, or microservices?

Yes, after gathering requirements such as team size, deployment needs, and scalability goals, it runs an assessment and offers recommendations on the most appropriate pattern, including guidance on event‑driven or modular monolith options.

Asked by Bartek Adamski · Dec 23, 2025

What kind of architecture diagrams can the skill produce?

It generates diagrams using Mermaid, PlantUML, or ASCII, which can be used for documentation or review. These visuals cover service boundaries, infrastructure topology, and data models.

Asked by Nour Khalil · Dec 6, 2025

How does Architecture Design (Grade A) help with database selection for a new startup project?

The tool uses a workflow that matches data characteristics, scale requirements, and consistency needs to recommend the most suitable database technology, whether SQL, NoSQL, or a specialized option. It then assists in designing the corresponding data model and generating an ER diagram in Mermaid.
