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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 90 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00038 | $0.03529 |
| Opus 5 | $0.00019 | $0.01765 |
| Sonnet 5 | $0.00008 | $0.00706 |
| Haiku 4.5 | $0.00004 | $0.00353 |
Grade A, and why
aws-ec2 scanned grade A with 1 finding 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.

AWS EC2
Deploy and manage Amazon EC2 compute instances for production, staging, and development workloads.
When to Use This Skill
- Launching new compute instances for application hosting
- Building golden AMIs for consistent deployments
- Setting up auto-scaling groups behind load balancers
- Migrating workloads to Spot instances for cost savings
- Troubleshooting instance connectivity, performance, or launch failures
- Creating launch templates for repeatable infrastructure
Prerequisites
- AWS CLI v2 installed and configured (
aws configure) - IAM permissions:
ec2:*,autoscaling:*,elasticloadbalancing:*,iam:PassRole - An existing VPC with subnets (see aws-vpc)
- SSH key pair created (
aws ec2 create-key-pair --key-name my-key --query 'KeyMaterial' --output text > my-key.pem)
Instance Type Selection Guide
| Category | Types | Use Case |
|---|---|---|
| General Purpose | t3, t3a, m6i, m7g | Web servers, small databases, dev/test |
| Compute Optimized | c6i, c7g | Batch processing, media encoding, ML inference |
| Memory Optimized | r6i, r7g, x2idn | In-memory caches, large databases |
| Storage Optimized | i3, i4i, d3 | Data warehousing, distributed file systems |
| Accelerated | p4d, g5, inf2 | ML training, GPU rendering, inference |
| Burstable | t3.micro-t3.2xlarge | Low-steady-state with occasional bursts |

What ships with it
1 file 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 is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,058 stars, last pushed 3mo ago), licensed MIT. It adds 38 tokens to every session and 3,529 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
