AWS Agent Skills is a collection of local instructions that help coding agents reason about AWS cloud services and engineering tasks. It supports agents working with areas such as identity, compute, storage, serverless, databases, networking, and security. The catalogue contains 18 service-focused skills and one plugin for using these capabilities with coding agents.
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 | $0.00031 | $0.02557 |
| Opus 5 | $0.00015 | $0.01278 |
| Sonnet 5 | $0.00006 | $0.00511 |
| Haiku 4.5 | $0.00003 | $0.00256 |
Grade A, and why
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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 371 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AWS RDS
Amazon Relational Database Service (RDS) provides managed relational databases including MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, and Aurora. RDS handles provisioning, patching, backups, and failover.

Core Concepts
DB Instance Classes
| Category | Example | Use Case |
|---|---|---|
| Standard | db.m6g.large | General purpose |
| Memory Optimized | db.r6g.large | High memory workloads |
| Burstable | db.t3.medium | Variable workloads, dev/test |
Storage Types
| Type | IOPS | Use Case |
|---|---|---|
| gp3 | 3,000-16,000 | Most workloads |
| io1/io2 | Up to 256,000 | High-performance OLTP |
| magnetic | N/A | Legacy, avoid |
Multi-AZ Deployments
- Multi-AZ Instance: Synchronous standby in different AZ
- Multi-AZ Cluster: One writer, two reader instances (Aurora-like)
Read Replicas
Asynchronous copies for read scaling. Can be cross-region.
Common Patterns
Create a PostgreSQL Instance
AWS CLI:
# Create DB subnet group
aws rds create-db-subnet-group \
--db-subnet-group-name my-db-subnet-group \
--db-subnet-group-description "Private subnets for RDS" \
--subnet-ids subnet-12345678 subnet-87654321
# Create security group (allow PostgreSQL from app)
aws ec2 create-security-group \
--group-name rds-postgres-sg \
--description "RDS PostgreSQL access" \
--vpc-id vpc-12345678
aws ec2 authorize-security-group-ingress \
--group-id sg-rds12345 \
--protocol tcp \
--port 5432 \
--source-group sg-app12345
# Create RDS instance
aws rds create-db-instance \
--db-instance-identifier my-postgres \
--db-instance-class db.t3.medium \
--engine postgres \
--engine-version 16.1 \
--master-username admin \
--master-user-password 'SecurePassword123!' \
--allocated-storage 100 \
--storage-type gp3 \
--db-subnet-group-name my-db-subnet-group \
--vpc-security-group-ids sg-rds12345 \
--multi-az \
--backup-retention-period 7 \
--storage-encrypted \
--no-publicly-accessible
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.

rds is a skill published in the GitHub repository itsmostafa/aws-agent-skills (1,150 stars, last pushed 7d ago), licensed MIT. It adds 31 tokens to every session and 2,557 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.
