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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00129 | $0.02857 |
| Opus 5 | $0.00064 | $0.01429 |
| Sonnet 5 | $0.00026 | $0.00571 |
| Haiku 4.5 | $0.00013 | $0.00286 |
Grade A, and why
aws-security 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 4d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AWS Security
STOP — Do not answer from general knowledge. Before responding to any security service question, match the user's request against the sub-skill registry below and follow its procedure. If the procedure says to load a reference file, you MUST read it before providing operational guidance. Never skip the routing step.
AWS Security services provide threat detection (GuardDuty), vulnerability management (Inspector), unified security dashboard and exposure analysis (Security Hub), compliance posture management (Security Hub CSPM), sensitive data discovery (Macie), investigation (Detective), and centralized log storage (Security Lake). Each service has dedicated reference procedures for configuration review and findings/investigation summarization.
This skill works with or without the AWS MCP server. When available, the AWS MCP server is recommended for sandboxed execution and audit logging. Procedures use standard AWS CLI syntax (aws <service> <command>).
See references/services-overview.md for service relationships, data formats, and cross-service integration patterns.
Global rules
-
Read-only APIs only. This skill and all its references use exclusively non-mutating APIs. NEVER reference, recommend, or invoke any API that creates, modifies, deletes, enables, disables, or otherwise mutates resource state or configuration — not even in prose recommendations. See service reference files for the complete allowed API list.
-
No severity judgements on configuration state. Present what is and is not configured factually. Do not assign severity labels, gap assessments, or editorial framing (e.g., "critical gap", "security issue") to configuration state.
-
No false-positive suppression recommendations. Focus on helping customers understand findings. Do not recommend suppression filters, archival rules, or finding dismissal.
-
Prioritize Attack Sequences in GuardDuty. Findings with type prefix
AttackSequence:represent correlated multi-step attacks. Always surface these first, before severity breakdown.
What ships with it
23 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-security is a skill published in the GitHub repository aws/agent-toolkit-for-aws (2,518 stars, last pushed today), licensed Apache-2.0. It adds 129 tokens to every session and 2,857 once invoked, about $0.0006 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.
