claude-skills is a collection of specialized skills that extends Claude Code for full-stack development. Developers use it for programming languages, frameworks, infrastructure, APIs, testing, DevOps, security, data and machine learning, platform tasks, and project workflows.
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.

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 | $0.00071 | $0.01858 |
| Opus 5.5 | $0.00028 | $0.00743 |
| Sonnet 5.5 | $0.00014 | $0.00372 |
| Haiku 4.5 | $0.00007 | $0.00186 |
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 12d 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.

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 (11,889 stars, last pushed today), licensed MIT. It adds 71 tokens to every session and 1,858 once invoked, about $0.0003 per session on Opus 5.5. 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.
