rds-oss

rds-oss is a skill for Claude Code, Codex from aws/agent-toolkit-for-aws. It costs 229 tokens per session (5,814 once invoked), scanned A, original, Apache-2.0.

An advisor for Amazon RDS databases using MySQL, MariaDB, or PostgreSQL, which are open-source database systems. It covers creating databases, upgrades, pricing commitments, connection proxies, and Blue/Green deployments, a way to prepare and switch to a changed copy with little downtime.

In plain words
What is it for?
Use it to plan RDS deployments and upgrades, estimate commitment savings, assess RDS Proxy, and analyze low-downtime database changes.
Why use it?
It helps make database changes safer and compare operational and cost choices before acting.

About the project

Agent Toolkit for AWS is a collection of AWS-supported MCP servers, skills, plugins, commands, and hooks that help AI coding agents build, deploy, and manage applications on AWS. It is used by developers working with AWS services through agents such as Claude Code, Codex, Cursor, and Kiro. The catalogue entries are the toolkit's own agent extensions for AWS development and operations.

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 →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

rds-oss 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 1 executable file (scripts/rds_commitment_pricing_analyzer.py), 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.

RDS OSS Advisor (MySQL, MariaDB, PostgreSQL)

Overview

Advisor for Amazon RDS on the open-source engines — MySQL, MariaDB, and PostgreSQL. Five decision areas:

  1. Instance creation — provision production-ready instances with best-practice defaults (latest version, Multi-AZ, encryption, Performance Insights, Secrets Manager password management)
  2. Upgrade planning — identify instance, enumerate targets, run live prechecks, flag plan regressions, surface pre/post checklists
  3. Commitment pricing — estimate RI and Database Savings Plan savings for steady workloads
  4. RDS Proxy evaluation — decide whether proxy is worth it, based on connection utilization and pinning risks
  5. Blue/Green deployments — plan low-downtime DDL or major upgrades, with DDL compatibility analysis

Produces cost estimates, precheck findings, and CLI commands. For instance creation, executes the create-db-instance call with production best practices. For upgrades, purchases, and switchovers — advisory only, never executes without explicit user confirmation.

Scoped to RDS open-source engines. For Aurora, use amazon-aurora. For Oracle, SQL Server, Db2, use the engine-specific skills.

The AWS MCP server is recommended for executing commands but is not required; all operations can also be performed via the AWS CLI.

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.
