What it does

AWS Security is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Covers AWS security services and workflows — Security Hub V2 (OCSF) findings, connectors, aggregators, automation rules, and security posture summaries; Security Hub CSPM (V1/ASFF) controls and compliance standards; GuardDuty threat findings; Inspector vulnerability findings; Macie sensitive data findings; Detective investigation; and Security Lake configuration and data aggregation. Applicable when questions involve security posture, Exposure findings, CSPM failed controls, threat findings, vulnerability…

Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 24 other files, including reference files (for example `references/detective-configuration.md`, `references/detective-investigations.md` and `references/detective.md`).

It sits in Security, covering Cloud security. It works with Amazon Web Services and Model Context Protocol. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 188af2f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • aws

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.aws.amazon.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

AWS Security loads about 3.4k tokens when it runs, and up to ~28k if it reads all its reference files. Until then it costs about 181 tokens; SKILL.md has 1,408 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~181
When it runs · the whole SKILL.md, loaded when a task matches
~3.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~28k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

  1. 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.

  2. 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.

  3. No false-positive suppression recommendations. Focus on helping customers understand findings. Do not recommend suppression filters, archival rules, or finding dismissal.

  4. Prioritize Attack Sequences in GuardDuty. Findings with type prefix AttackSequence: represent correlated multi-step attacks. Always surface these first, before severity breakdown.

  5. Prioritize Exposure findings in Security Hub. Exposure findings (attack paths, resource exposure) represent Security Hub's unique cross-service correlation. Surface these first in any findings summary.

  6. Expensive operations require explicit request. MUST NOT paginate through all member accounts by default. Per-account enumeration only executes if the user explicitly requests detailed account-level information. Use statistics/count APIs where available (e.g., get-coverage-statistics).

  7. Match the user's language. Respond in the same language the user writes in.

  8. Verify, don't guess. If you cannot confirm a fact from a reference file or API output, say so.

  9. Sensitive data disclosure. When a procedure produces output that may contain sensitive information (full finding bodies, IP addresses, resource identifiers, network configurations, threat intelligence details), present a summary first. Note what sensitive data the full output contains. Display the complete raw response only when the caller explicitly requests it.

How this skill works

  1. Find the sub-skill — Match the user's request against the sub-skill registry below. Match on meaning, not exact wording. If ambiguous, ask: "Are you checking configuration, or do you need a findings summary?"

  2. If a sub-skill matches — read references/{sub-skill-id}.md and follow its procedure.

  3. If no sub-skill matches — answer from the service reference files listed below. Load references/services-overview.md for cross-service context, or the relevant service reference file (e.g., references/guardduty.md) for API scope and severity scoring questions.

  4. Cross-service overview — When the user asks about overall security posture across multiple services, start with references/services-overview.md, then route to relevant sub-skills.

Security considerations

  • Logging and monitoring: Verify CloudTrail is enabled for security service and Organizations API calls, CloudTrail log file validation is active, and CloudWatch metric filters or alarms exist for anomalous privileged read patterns such as unexpected volume, unusual principals, or unexpected regions.
  • Encryption and destinations: Verify publishing or export destinations such as S3 buckets, SNS topics, and CloudWatch Logs use KMS encryption at rest and TLS in transit. For downstream S3 or SNS destinations, verify resource policies use aws:SourceArn and aws:SourceAccount condition keys where applicable.
  • Notification recipients: Verify SNS topic subscriptions and other security alarm recipients are restricted to authorized security personnel, and periodically audit subscription endpoints.
  • Credential management: Confirm CLI execution is using temporary credentials such as IAM roles or AWS SSO. Verify third-party integration credentials, API tokens, or connector secrets are stored in AWS Secrets Manager or AWS Systems Manager Parameter Store rather than plaintext configuration files or environment variables.
  • Security references: Consult AWS Security Hub best practices, AWS CloudTrail security best practices, IAM security best practices, and the AWS Well-Architected Security Pillar for current service guidance.
  • Sensitive data: Security service outputs may contain sensitive information such as IP addresses, resource identifiers, account IDs, vulnerability details, exposure paths, and threat intelligence. Classification and handling requirements are customer-specific; do not store or share outputs in unprotected channels without verifying organizational data handling policies.

Can I use AWS Security in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aws/agent-toolkit-for-aws --skill aws-security -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/aws-security, .gemini/skills/aws-security, .github/skills/aws-security and .opencode/skills/aws-security in your project.

What does AWS Security need to run?

Going by SKILL.md and its folder, AWS Security needs the command-line tools its instructions call (aws).

Does AWS Security access the network?

SKILL.md names 1 domain. As links in the text: docs.aws.amazon.com. This is read from the text; nothing was executed.

Is AWS Security safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does AWS Security use?

AWS Security is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does AWS Security use?

About 3.4k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 25k tokens, read only when the agent opens those files.
