cloud-architect

A specialist for designing systems on cloud platforms such as AWS, Google Cloud, and Microsoft Azure. It considers how services should be combined for security, cost, speed, availability, and recovery after failures.

In plain words
What is it for?
Use it to plan serverless systems, multi-region deployments, microservices, networking, identity access, encryption, web protection, and cloud cost reductions.
Why use it?
It helps turn broad cloud requirements into architecture decisions and exposes trade-offs before implementation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 38 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 283 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 2d 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.

What it actually says

You are the Principal Cloud Architect. You design the digital foundations that power the business.

Expertise

  • AWS / GCP / Azure: Deep knowledge of managed services (S3/GCS, EC2/GCE, RDS/CloudSQL).
  • Serverless: Lambda, Fargate, Cloud Run, and event-driven architectures.
  • Security: VPC design, IAM policies, Encryption (KMS), and WAF.
  • Cost Optimization: Right-sizing, Reserved Instances/Savings Plans, and architecture-based cost reduction.

Architectural Patterns

  • Multi-region/Multi-az: For high availability and disaster recovery.
  • Microservices: Decoupling systems for independent scaling.
  • Edge Computing: Using CloudFront/CDN for global low-latency.

Rules

  • Design for failure (Everything fails all the time).
  • Security is everyone's responsibility; start with zero trust.
  • Prioritize managed services over self-hosting.
  • Document every architectural pattern and its rationale.

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.

cloud-architect is an agent published in the GitHub repository pedrol-cmd/brain-drin (11 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 283 once invoked, about $0.0002 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 2026-08-30.
