What is architecture-design?

A software architecture planning guide for deciding how an application is structured, which technologies it uses, and how it is deployed. It covers styles such as monoliths, microservices, event-driven systems, and serverless applications.

Use it to plan a new system, modernize an older one, compare technology choices, create architecture diagrams, or prepare an implementation roadmap.

It helps turn requirements into a documented system design before implementation, including concerns such as security, speed, growth, and integrations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.02295
Opus 5	$0.00041	$0.01148
Sonnet 5	$0.00016	$0.00459
Haiku 4.5	$0.00008	$0.00230

Security

Grade A, and why

architecture-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture Design

Overview

This skill enables you to design comprehensive software solution architectures including system components, technology stacks, integration patterns, scalability strategies, and deployment models.

Core Capabilities

When activated, this skill provides:

Requirements Analysis & Architecture Planning
- Analyze functional and non-functional requirements
- Identify architectural drivers (scalability, security, performance)
- Define system boundaries and constraints
- Establish architecture goals and success criteria
System Architecture Design
- Design layered/tiered architectures
- Create microservices and domain-driven designs
- Design event-driven and message-based systems
- Plan serverless and cloud-native architectures
- Design monolithic, modular monolithic, or distributed systems
Technology Stack Selection
- Evaluate and justify programming languages and frameworks
- Select databases with rationale (SQL, NoSQL, time-series, graph)
- Choose middleware and integration platforms (message queues, API gateways)
- Select infrastructure and cloud platforms (assess vendor lock-in)
- Recommend CI/CD and DevOps tools
- Document technology decisions in ADRs with alternatives considered
- Assess team skills and training needs for new technologies
Architecture Patterns & Best Practices
- Apply design patterns (MVC, MVVM, Clean Architecture, Hexagonal)
- Implement integration patterns (REST, GraphQL, gRPC, message queues)
- Design for scalability (horizontal/vertical, caching, CDN)
- Implement security patterns (OAuth, JWT, zero-trust)
- Apply resilience patterns (circuit breakers, retries, bulkheads)
Documentation & Deliverables
- Create C4 model diagrams in Mermaid format (Context, Container, Component, Code)
- Generate Mermaid diagrams (class, sequence, deployment)
- Produce architecture decision records (ADRs)
- Write technical specifications and API contracts
- Create implementation roadmaps and migration plans

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architecture-design is a skill published in the GitHub repository DauQuangThanh/hanoi-rainbow (17 stars, last pushed 7mo ago), licensed MIT. It adds 81 tokens to every session and 2,295 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
