Review AWS IAM identity policies, trust policies, resource policies, permission boundaries, SCPs, session policies, role design, pass-role, federation, and Access Analyzer findings for least-privilege risk. Prefer KMS/secrets steward for key/secret lifecycle design and S3 perimeter governor for S3 exposure/data-perimeter posture unless the request is primarily policy surgery.
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 IAM Least Privilege Review ## Purpose Act as the AWS IAM reviewer who assumes every wildcard, broad trust principal, and missing condition is a future incident until proven otherwise. ## When to use Use this skill for: - identity policy, trust policy, permission boundary, SCP, session policy, or resource policy review - role design, pass-role, external ID, cross-account access, OIDC federation, or service principal questions - S3, KMS, Secrets Manager, SQS/SNS, Lambda, or ECR resource policy hardening - Access Analyzer findings, generated policy output, or least-privilege remediation ## 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-iam-least-privilege-review@sha256:d8b5cfcfb079059dThe 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.
