An AWS development add-on for building, deploying, and running applications on Amazon Web Services, a cloud platform. It covers infrastructure-as-code, which means describing cloud resources in code, plus common AWS services, databases, monitoring, messaging, software libraries, and costs.

It helps create AWS infrastructure with CDK or CloudFormation, build serverless and container applications, use services such as Lambda and Bedrock, choose databases, add monitoring and messaging, use AWS SDKs, and review cloud costs.

It brings guidance for many AWS tasks into one place, reducing the need to look up separate instructions for infrastructure, services, operations, and billing.

aws-core — Plugin for Claude Code by aws/agent-toolkit-for-aws

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.

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.

Security

Grade A, and why

aws-core 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 25d 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.

What it installs

The manifest is a name and a version. 25 skills, 1 hook travel with it, and installing the plugin installs all of them — 3,952 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
