ingress-debug

ingress-debug is a skill for Claude Code, Codex from scitix/siclaw. It costs 49 tokens per session (1,796 once invoked), scanned A, original, Apache-2.0.

A diagnostic guide for Kubernetes Ingress, which routes outside web traffic to services inside a cluster. It checks routing rules, the IngressClass, backend services, TLS settings, and the health of the routing controller.

In plain words
What is it for?
Use it when traffic cannot reach a service through an Ingress, host or path rules do not match, a backend is unreachable, or HTTPS setup fails.
Why use it?
It helps find why an application returns 404 or 502 errors, has TLS problems, or receives no external address. It reports the cause without changing routes, services, or certificates.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ingress-debug 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 1mo 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.

Ingress Failure Diagnosis

When external traffic cannot reach a Service through an Ingress — 404, 502, TLS errors, or no address assigned — follow this flow to identify the root cause.

Scope: This skill is for diagnosis only. Once you identify the root cause, report it to the user and stop. Do NOT attempt to modify Ingress resources, Services, or TLS secrets — that should be left to the user.

Diagnostic Flow

1. Check Ingress status

kubectl get ingress <ingress-name> -n <ns>

Note:

  • CLASS — the IngressClass being used
  • HOSTS — configured hostnames
  • ADDRESS — the external IP/hostname assigned by the controller. If empty, the controller has not processed this Ingress.
  • PORTS — 80, 443 (if TLS is configured)

2. Describe the Ingress

kubectl describe ingress <ingress-name> -n <ns>

Focus on:

  • Rules — host and path routing rules with their backend services
  • TLS — configured TLS hosts and secret names
  • Default backend — the fallback backend if no rule matches
  • Events — errors from the Ingress controller (sync failures, configuration errors)
  • Annotations — controller-specific annotations that affect routing behavior

3. Verify backend Service and Endpoints

For each backend referenced by the Ingress rules:

kubectl get svc <backend-service> -n <ns>
kubectl get endpoints <backend-service> -n <ns>

If the backend Service has no endpoints, traffic will fail with 502/503. Use the service-debug skill for deeper diagnosis.

4. Check Ingress controller health

Find the Ingress controller pods (common labels):

kubectl get pods -n ingress-nginx -l app.kubernetes.io/name=ingress-nginx

If not using nginx-ingress, check other common namespaces:

kubectl get pods --all-namespaces -l app.kubernetes.io/component=controller | head -20

Verify controller pods are Running and Ready. Check controller logs for errors:

kubectl logs -n <controller-ns> <controller-pod> --tail=100

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.
