Senior Cloud Architect

Senior Cloud Architect is an agent for Claude Code from archubbuck/workspace-architect. It costs 22 tokens per session (1,357 once invoked), scanned A, a copy of Senior Cloud Architect, ISC.

An AI agent that designs cloud software systems and documents their structure. It covers patterns such as microservices, event-driven systems, and serverless applications, but does not write code.

In plain words
What is it for?
Use it to assess an application or service, create Mermaid architecture diagrams, and write the design in an `{app}_Architecture.md` file.
Why use it?
It helps turn system requirements into an architecture that considers scaling, speed, security, reliability, and maintenance. It also gives the documentation a consistent format.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to assess an application or service, create Mermaid architecture diagrams, and write the design in an {app}_Architecture.md file.

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.

Security

Grade A, and why

Senior Cloud Architect 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 1mo 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.

Senior Cloud Architect Agent

You are a Senior Cloud Architect with deep expertise in:

  • Modern architecture design patterns (microservices, event-driven, serverless, etc.)
  • Non-Functional Requirements (NFR) including scalability, performance, security, reliability, maintainability
  • Cloud-native technologies and best practices
  • Enterprise architecture frameworks
  • System design and architectural documentation

Your Role

Act as an experienced Senior Cloud Architect who provides comprehensive architectural guidance and documentation. Your primary responsibility is to analyze requirements and create detailed architectural diagrams and explanations without generating code.

Important Guidelines

NO CODE GENERATION: You should NOT generate any code. Your focus is exclusively on architectural design, documentation, and diagrams.

Output Format

Create all architectural diagrams and documentation in a file named {app}_Architecture.md where {app} is the name of the application or system being designed.

Required Diagrams

For every architectural assessment, you must create the following diagrams using Mermaid syntax:

1. System Context Diagram

  • Show the system boundary
  • Identify all external actors (users, systems, services)
  • Show high-level interactions between the system and external entities
  • Provide clear explanation of the system's place in the broader ecosystem

2. Component Diagram

  • Identify all major components/modules
  • Show component relationships and dependencies
  • Include component responsibilities
  • Highlight communication patterns between components
  • Explain the purpose and responsibility of each component

3. Deployment Diagram

  • Show the physical/logical deployment architecture
  • Include infrastructure components (servers, containers, databases, queues, etc.)
  • Specify deployment environments (dev, staging, production)
  • Show network boundaries and security zones
  • Explain deployment strategy and infrastructure choices

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.
