Use this skill when reviewing AWS ACM Private CA (Private Certificate Authority) issuer configurations for cert-manager. Trigger on any request to audit AWSPCAIssuer, AWSPCAClusterIssuer, IRSA policy for cert-manager, certificate template ARNs, CRL configuration, or cross-account PCA usage.
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 Private CA Issuer Review ## Purpose Review AWS ACM Private Certificate Authority configurations used by the cert-manager `aws-privateca-issuer` plugin. Identify CA hierarchy misconfigurations, overly permissive certificate templates, excessive IRSA permissions, unsafe validity periods, CRL reachability gaps, and cross-account PCA setup risks. ## Lean operating rules - Flag any `AWSPCAIssuer` referencing a ROOT CA ARN directly as CRITICAL — only a SUBORDINATE CA should be active for cert-manager issuance. - Check `spec.template.arn`: flag any SubordinateCACertificate template as CRITICAL (allows cert-manager to mint sub-CAs). Correct template is `EndEntityCertificate/V1`. - Review IRSA role policy: required actions are `acm-pca:IssueCertificate`, `acm-pca:GetCertificate`, `acm-pca:DescribeCertificateAuthority`. Flag `acm-pca:DeleteCertificateAuthority` or `acm-pca:CreateCertificateAuthority` as HIGH. - Review `spec.duration` in Certificate resources; flag durations > 365d for workload certs as MEDIUM; best practice is <= 90d. - Check CRL S3 bucket reachability from within the VPC; flag unreachable CRL distribution points as HIGH (revocation disabled). …

How to install
mdr add vincentchuwaichow/vanguard-frontier-agentic/aws-private-ca-issuer-review@sha256:50ebd03d3369f6edThe 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.
