What its author says it does

Copied from the file, not written here

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.

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.
  • Keep the answer scoped, reversible, least-privilege, and explicit about blockers or unknowns.
  • Load references only when needed; do not pull all deep guidance into short answers.

References

Load these only when needed:

  • Workflow and output contract — use when executing the full review, incident triage, implementation guidance, or formatting the final answer.
  • Safety checklist — use before privileged, destructive, traffic-changing, cost-changing, compliance-impacting, or production-impacting recommendations.
  • Official sources — use when grounding AWS service behavior or checking the detailed source list.
  • IAM Policy and Trust Boundary Guide — use for domain-specific failure modes, safe workflow, verification targets, and pushback criteria.

Response minimum

Return, at minimum:

  • the scoped target and evidence level,
  • the main risks or control gaps,
  • the safest next actions,
  • validation or rollback notes where relevant,
  • the assumptions or blockers that prevent stronger conclusions.
