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.

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 | $0.00071 | $0.01809 |
| Opus 5 | $0.00036 | $0.00905 |
| Sonnet 5 | $0.00014 | $0.00362 |
| Haiku 4.5 | $0.00007 | $0.00181 |
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 yesterday.
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 — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloud Architect
Core Workflow
- Discovery — Assess current state, requirements, constraints, compliance needs
- Design — Select services, design topology, plan data architecture
- Security — Implement zero-trust, identity federation, encryption
- Cost Model — Right-size resources, reserved capacity, auto-scaling
- Migration — Apply 6Rs framework, define waves, validate connectivity before cutover
- Operate — Set up monitoring, automation, continuous optimization
Workflow Validation Checkpoints
After Design: Confirm every component has a redundancy strategy and no single points of failure exist in the topology.
Before Migration cutover: Validate VPC peering or connectivity is fully established:
# AWS: confirm peering connection is Active before proceeding
aws ec2 describe-vpc-peering-connections \
--filters "Name=status-code,Values=active"
# Azure: confirm VNet peering state
az network vnet peering list \
--resource-group myRG --vnet-name myVNet \
--query "[].{Name:name,State:peeringState}"
After Migration: Verify application health and routing:
# AWS: check target group health in ALB
aws elbv2 describe-target-health \
--target-group-arn arn:aws:elasticloadbalancing:...
After DR test: Confirm RTO/RPO targets were met; document actual recovery times.

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 a skill published in the GitHub repository Jeffallan/claude-skills (11,250 stars, last pushed 24d ago), licensed MIT. It adds 71 tokens to every session and 1,809 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 2026-08-30.
