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. 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.co

# Detecting SSL Certificate Issues ## Overview This skill is the second-level cert audit, run after `analyzing-tls-config` clears the protocol+cipher+expiry+hostname basics. It surfaces issues that don't break the handshake today but make the cert fragile or open to soft-bypass attacks: missing OCSP stapling forces clients to phone home to the CA (privacy + latency hit), missing Certificate Transp
What does the detecting-ssl-cert-issues skill do?
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.

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill detecting-ssl-cert-issues --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,596 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
