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 | $0.00039 | $0.00617 |
| Opus 5 | $0.00019 | $0.00309 |
| Sonnet 5 | $0.00008 | $0.00123 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
aws-ec2-setup 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 11d 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.

AWS EC2 Setup
Table of Contents
Overview
Amazon EC2 provides resizable compute capacity in the cloud. Launch and configure virtual servers with complete control over networking, storage, and security settings. Scale automatically based on demand.
When to Use
- Web application servers
- Application backends and APIs
- Batch processing and compute jobs
- Development and testing environments
- Containerized applications (ECS)
- Kubernetes clusters (EKS)
- Database servers
- VPN and proxy servers
Quick Start
Minimal working example:
# Create security group
aws ec2 create-security-group \
--group-name web-server-sg \
--description "Web server security group" \
--vpc-id vpc-12345678
# Add ingress rules
aws ec2 authorize-security-group-ingress \
--group-id sg-0123456789abcdef0 \
--protocol tcp \
--port 80 \
--cidr 0.0.0.0/0
aws ec2 authorize-security-group-ingress \
--group-id sg-0123456789abcdef0 \
--protocol tcp \
--port 443 \
--cidr 0.0.0.0/0
aws ec2 authorize-security-group-ingress \
--group-id sg-0123456789abcdef0 \
--protocol tcp \
--port 22 \
--cidr YOUR_IP/32
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Use security groups for network control
- Attach IAM roles for AWS access
- Enable CloudWatch monitoring
- Use AMI for consistent deployments
- Implement auto-scaling for variable load
- Use EBS for persistent storage
- Enable termination protection for production
- Keep systems patched and updated
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.

aws-ec2-setup is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (336 stars, last pushed 6mo ago), licensed MIT. It adds 39 tokens to every session and 617 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.
