What is aws-cloudformation-rds?

A collection of AWS CloudFormation patterns for Amazon RDS, AWS's managed database service. It covers database instances, Aurora clusters, networking, settings, credentials, and stack links.

Creating MySQL, PostgreSQL, or Aurora databases, multi-zone deployments, subnet and parameter groups, security groups, Secrets Manager links, and cross-stack references.

It provides a known template structure for defining database infrastructure as code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.02795
Opus 5.5	$0.00026	$0.01118
Sonnet 5.5	$0.00013	$0.00559

Security

Grade A, and why

aws-cloudformation-rds 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 2mo 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 CloudFormation RDS Database

Overview

Create production-ready Amazon RDS infrastructure using AWS CloudFormation templates. Covers RDS instances (MySQL, PostgreSQL, Aurora), DB clusters, multi-AZ deployments, parameter groups, subnet groups, security groups, and cross-stack references.

When to Use

Creating RDS instances (MySQL, PostgreSQL, Aurora) or DB clusters with read replicas
Setting up multi-AZ deployments or configuring parameter/subnet groups
Integrating with Secrets Manager or implementing cross-stack references

Quick Reference

Component	CloudFormation Type	Use Case
DB Instance	`AWS::RDS::DBInstance`	Single database instance
DB Cluster	`AWS::RDS::DBCluster`	Aurora cluster
DB Subnet Group	`AWS::RDS::DBSubnetGroup`	VPC deployment
Parameter Group	`AWS::RDS::DBParameterGroup`	Database configuration
Security Group	`AWS::EC2::SecurityGroup`	Network access control
Secrets Manager	`AWS::SecretsManager::Secret`	Credential storage

Instructions

Step 1 — Define Database Parameters

Use AWS-specific parameter types for validation.

Parameters:
  DBInstanceClass:
    Type: AWS::RDS::DBInstance::InstanceType
    Default: db.t3.micro
    AllowedValues: [db.t3.micro, db.t3.small, db.t3.medium]

  Engine:
    Type: String
    Default: mysql
    AllowedValues: [mysql, postgres, aurora-mysql, aurora-postgresql]

  MasterUsername:
    Type: String
    Default: admin
    AllowedPattern: "^[a-zA-Z][a-zA-Z0-9]*$"
    MinLength: 1
    MaxLength: 16

  MasterUserPassword:
    Type: String
    NoEcho: true
    MinLength: 8
    MaxLength: 41

See template-structure.md for advanced parameter patterns, mappings, conditions, and cross-stack references.

Step 2 — Create DB Subnet Group

Required for VPC deployment with subnets in different AZs.

DBSubnetGroup:
  Type: AWS::RDS::DBSubnetGroup
  Properties:
    DBSubnetGroupDescription: Subnet group for RDS
    SubnetIds:
      - !Ref PrivateSubnet1
      - !Ref PrivateSubnet2

What ships with it

8 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.

Changes

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.
