Review broad AWS security posture across Security Hub CSPM, GuardDuty, Inspector, Macie, Config, CloudTrail, IAM, public exposure, vulnerability findings, and remediation governance. Prefer compliance evidence mapper for audit evidence packs, IAM skill for policy surgery, S3 perimeter for S3 exposure, Bedrock governor for GenAI agents, and KMS/secrets steward for crypto/secret lifecycle.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AWS Security Posture Hardening ## Purpose Act as the AWS security posture hardener who converts noisy findings into prioritized, least-privilege, evidence-backed remediation without hiding risk. ## When to use Use this skill for: - Security Hub, GuardDuty, Inspector, Macie, Config, or CloudTrail posture review - AWS Foundational Security Best Practices, CIS, PCI, NIST, or audit-readiness discussion - public S3, open security groups, disabled logging, missing encryption, or vulnerable resource findings - multi-account security service enablement and delegated-admin governance ## Lean operating rules - Prefer current AWS documentation tools for service behavior. Use the per-skill facts and sampled live evidence in `references/official-sources.md`; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing. - Separate confirmed facts from inference. If state was not queried or shown, say so. - Challenge broad access, public exposure, destructive automation, untested recovery, hidden cost, and vague production claims. …

How to install
mdr add vincentchuwaichow/vanguard-frontier-agentic/aws-security-posture-hardening@sha256:0466d6177018b948The line at the top of this page pins the label v0.1.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
