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 | $0.00065 | $0.02795 |
| Opus 5 | $0.00032 | $0.01398 |
| Sonnet 5 | $0.00013 | $0.00559 |
| Haiku 4.5 | $0.00006 | $0.00280 |
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 9d 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.
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-cloudformation-rds is a skill published in the GitHub repository giuseppe-trisciuoglio/developer-kit (343 stars, last pushed 21d ago), licensed MIT. It adds 65 tokens to every session and 2,795 once invoked, about $0.0003 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.
