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 | $0.00051 | $0.01908 |
| Opus 5 | $0.00026 | $0.00954 |
| Sonnet 5 | $0.00010 | $0.00382 |
| Haiku 4.5 | $0.00005 | $0.00191 |
Grade A, and why
cert-manager scanned grade A with 0 findings 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 7d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

CRD Reference
| CRD | API | Scope | Purpose | Key Fields |
|---|---|---|---|---|
| Issuer | cert-manager.io/v1 |
Namespaced | Certificate authority within a namespace. ACME, self-signed, CA, Vault, Venafi. | spec.acme, spec.ca, spec.selfSigned, spec.vault, spec.venafi |
| ClusterIssuer | cert-manager.io/v1 |
Cluster | Cluster-wide issuer — can issue certs in any namespace. Same spec as Issuer. | Same as Issuer |
| Certificate | cert-manager.io/v1 |
Namespaced | Request a TLS certificate from an issuer. Creates Secret with cert+key. | spec.secretName, spec.issuerRef, spec.dnsNames[], spec.commonName, spec.duration, spec.renewBefore, spec.privateKey (algorithm, size, rotationPolicy), spec.usages[], spec.subject |
| CertificateRequest | cert-manager.io/v1 |
Namespaced | Low-level CSR resource. Usually created automatically by Certificate. | spec.issuerRef, spec.request (base64 CSR), spec.duration, spec.isCA |
ACME Resources
| CRD | API | Purpose |
|---|---|---|
| Order | acme.cert-manager.io/v1 |
ACME order lifecycle. Created automatically by Certificate with ACME issuer. |
| Challenge | acme.cert-manager.io/v1 |
ACME challenge (DNS-01, HTTP-01). Created automatically per domain in Order. |
Issuer Types
| Type | Configuration | Use Case |
|---|---|---|
| ACME | spec.acme.server + spec.acme.solvers[] |
Let's Encrypt, ZeroSSL, Buypass |
| SelfSigned | spec.selfSigned: {} |
Internal CA bootstrap, testing |
| CA | spec.ca.secretName |
Sign with existing CA key+cert in Secret |
| Vault | spec.vault |
HashiCorp Vault PKI |
| Venafi | spec.venafi |
Venafi TPP/Cloud |
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.

cert-manager is a skill published in the GitHub repository Aidas-dev/k8s-agent-skills (2 stars, last pushed 24d ago), licensed MIT. It adds 51 tokens to every session and 1,908 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
