Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00080 | $0.02941 |
| Opus 5 | $0.00040 | $0.01470 |
| Sonnet 5 | $0.00016 | $0.00588 |
| Haiku 4.5 | $0.00008 | $0.00294 |
Grade A, and why
ssl-certificate-manager scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- `kubectl`, `helm`, `openssl`, `dig`, `curl`, `jq`, `yq`. How it starts
The opening of the file, as written. The whole thing — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use
- User says "audit our certs", "some cert is expiring", "install cert-manager", "switch to Let's Encrypt", "rotate the ingress cert", or asks about HTTP-01 vs DNS-01.
- CI or monitoring flagged a cert expiring within 30 days.
- Migrating from manual cert upload (Secret holding
tls.crt/tls.key) to automated issuance. - A wildcard cert is required (forces DNS-01).
- A mutual-TLS setup needs an internal CA (private PKI; this skill can drive cert-manager's CA issuer).
Do not use this skill for code-signing certs, SSH keys, or client certs unrelated to TLS termination.
Inputs
- Kubeconfig context; list of target namespaces.
- List of hostnames that must be covered (may include wildcards).
- Issuance strategy: HTTP-01 (public, per-host), DNS-01 (wildcards or private), or an internal CA.
- DNS provider (Route53, Cloud DNS, Cloudflare, Azure DNS) and credentials for DNS-01.
- ACME contact email.
- Alert destinations: reuse the Alertmanager config from
monitoring-setup.
Outputs
- A cert inventory CSV/table:
host | issuer | NotBefore | NotAfter | daysLeft | source (cert-manager | manual | external) | namespace | secret. - cert-manager installed and healthy.
ClusterIssuerresources:letsencrypt-staging,letsencrypt-prod, optionallyinternal-ca.Certificateresources for every managed host.- Alertmanager rules for
CertExpiringWarn(<30d) andCertExpiringSoon(<7d) — already defined inmonitoring-setup/references/alertmanager-rules-template.yaml. - A rotation runbook: how to force-renew without downtime, how to roll back.
Tool dependencies
kubectl,helm,openssl,dig,curl,jq,yq.cmctl(cert-manager CLI) for issue/renew/status.- Kubernetes MCP, filesystem MCP, optionally AWS/GCP/Azure MCP for DNS-01 IAM setup.
Procedure
- Detect the stack. Run these read-only commands and record findings:
kubectl config current-context— confirm a Kubernetes cluster is addressable. No cluster → stop; this skill requireskubernetes.kubectl get crd certificates.cert-manager.io 2>/dev/null— cert-manager installed?helm list -A 2>/dev/null | grep -Ei 'cert-manager|jetstack'— cert-manager via Helm?kubectl get ingressclass 2>/dev/null— what ingress controller is in use (nginx, traefik, istio, contour)?kubectl get secrets -A --field-selector type=kubernetes.io/tls -o name 2>/dev/null | head— existing TLS secrets (manual uploads vs managed)?ls aws-load-balancer-controller/ 2>/dev/nullorkubectl get crd targetgroupbindings.elbv2.k8s.aws 2>/dev/null— AWS ALB/ACM in the mix instead?
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ssl-certificate-manager is a skill published in the GitHub repository tahirraufkeeyu/software-development-agent-stack--sdas (18 stars, last pushed 4mo ago), licensed MIT. It adds 80 tokens to every session and 2,941 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
