Audit a target's TLS certificate beyond protocol/expiry — chain ordering, OCSP stapling, revocation status, Certificate Transparency presence, key-usage flags, and over-broad wildcards. Use when: TLS handshake already passes (skill #1 analyzing-tls-config cleared) but you suspect the cert posture is fragile. Auditors flag this during SOC2 readiness when a renewal slipped or an intermediate was rotated. Threshold: missing OCSP stapling on production, fewer than 2 SCTs in the cert, intermediate served out of order, key usage missing digitalSignature/keyEncipherment, revoked cert presented, or wildcard scope of 2-level (e.g., *.com is rejection; *.api.example.com is fine). Trigger with: "check cert revocation", "audit ocsp", "ct log check", "cert chain audit".
