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

aws-skill 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 1mo ago.

The scan reads SKILL.md. This mod also ships 9 executable files (skill-real.js, skill.js, src/env.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Skill

Interact with Amazon Web Services (AWS) directly from the command line or through MCP. This skill provides secure, authenticated access to core AWS services including S3 storage, EC2 compute, and Lambda serverless functions.

What is AWS?

Amazon Web Services (AWS) is the world's most comprehensive cloud computing platform, offering over 200 services for compute, storage, databases, networking, and more. This skill focuses on the most commonly used services:

  • S3 (Simple Storage Service): Object storage for files, backups, and static assets
  • EC2 (Elastic Compute Cloud): Virtual servers for running applications
  • Lambda: Serverless compute for running code without managing servers

When to Use This Skill

Use this skill when you need to:

  • List, upload, or download files from S3 buckets
  • Check running EC2 instances and their status
  • Invoke Lambda functions programmatically
  • Automate AWS operations without switching to the AWS Console

Common scenarios:

  • "Upload this build artifact to S3"
  • "Show me all running EC2 instances in production"
  • "Invoke the data-processing Lambda function"
  • "Download the latest backup from S3"

Prerequisites

  1. AWS Account: You need an active AWS account
  2. AWS Credentials: IAM access key ID and secret access key
  3. IAM Permissions: Your credentials need appropriate permissions for the services you'll use

Getting AWS Credentials

  1. Log into AWS Console
  2. Navigate to IAM → Users → Your User
  3. Security Credentials tab → Create Access Key
  4. Choose "Command Line Interface (CLI)"
  5. Save the Access Key ID and Secret Access Key

Security Note: Never commit AWS credentials to source control. This skill stores them securely in your system keychain.

Configuration

Create a skill.config.toml file or configure after installation:

[config]
aws_access_key_id = "AKIAIOSFODNN7EXAMPLE"
aws_secret_access_key = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
region = "us-east-1"

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.
