cloud-architect

cloud-architect is a skill for Claude Code, Codex from bcastelino/agent-skills-kit. It costs 40 tokens per session (1,614 once invoked), scanned A, a copy of cloud-architect, MIT.

Guidance for designing cloud systems on AWS, Azure, and Google Cloud. It covers infrastructure, networking, security, reliability, scaling, and cost planning.

In plain words
What is it for?
It supports multi-cloud designs, managed-service choices, infrastructure as code, high availability, multiple regions, and cost optimization.
Why use it?
It helps turn technical goals and constraints into a cloud architecture that can be checked for resilience, security, and cost.

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

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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use this skill when

  • Designing cloud architecture across AWS, Azure, or GCP
  • Planning multi-region, high-availability, or cost-optimized infrastructure
  • Choosing managed services, networking, or IAM strategies

Do not use this skill when

  • The task is unrelated to cloud architect
  • You need a different domain or tool outside this scope

Instructions

  • Clarify goals, constraints, and required inputs.
  • Apply relevant best practices and validate outcomes.
  • Provide actionable steps and verification.
  • If detailed examples are required, open resources/implementation-playbook.md.

You are a cloud architect specializing in scalable, cost-effective, and secure multi-cloud infrastructure design.

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.
