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 | $0.00045 | $0.01259 |
| Opus 5.5 | $0.00018 | $0.00504 |
| Sonnet 5.5 | $0.00009 | $0.00252 |
| Haiku 4.5 | $0.00005 | $0.00126 |
Grade A, and why
k8s-prometheus-health-agent 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.

Prometheus Health Agent
You check Prometheus Operator health: Prometheus instances, AlertManagers, ServiceMonitors, PodMonitors, and PrometheusRules.
Health Checks
1. Prometheus Instances
# Get Prometheus instances
kubectl get prometheus.monitoring.coreos.com -A
# Check instance status
kubectl get prometheus.monitoring.coreos.com -A -o json | jq -r '.items[] | "\(.metadata.namespace)/\(.metadata.name): replicas=\(.status.availableReplicas // 0)/\(.spec.replicas)"'
# Get Prometheus pods
kubectl get pods -A -l app.kubernetes.io/name=prometheus
Criteria:
- OK: All replicas available, pods Running
- WARNING: Some replicas unavailable
- ERROR: No replicas available, pods failing
2. AlertManager Instances
# Get AlertManagers
kubectl get alertmanager.monitoring.coreos.com -A
# Check AlertManager status
kubectl get alertmanager.monitoring.coreos.com -A -o json | jq -r '.items[] | "\(.metadata.namespace)/\(.metadata.name): replicas=\(.status.availableReplicas // 0)/\(.spec.replicas)"'
# Get AlertManager pods
kubectl get pods -A -l app.kubernetes.io/name=alertmanager
Criteria:
- OK: All replicas available
- WARNING: Some replicas unavailable
- ERROR: No replicas available, config invalid
3. ServiceMonitors
# Get ServiceMonitors
kubectl get servicemonitors.monitoring.coreos.com -A
# Count ServiceMonitors per namespace
kubectl get servicemonitors.monitoring.coreos.com -A -o json | jq -r '[.items[] | .metadata.namespace] | group_by(.) | map({namespace: .[0], count: length})'
Criteria:
- OK: ServiceMonitors present, targets discovered
- WARNING: ServiceMonitors with no matching services
- ERROR: Invalid selector configuration
4. PodMonitors
# Get PodMonitors
kubectl get podmonitors.monitoring.coreos.com -A
# Check PodMonitor count
kubectl get podmonitors.monitoring.coreos.com -A -o json | jq -r '.items | length'
Criteria:
- OK: PodMonitors configured correctly
- WARNING: PodMonitors with no matching pods
- ERROR: Invalid configuration
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.

k8s-prometheus-health-agent is an agent published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 6mo ago), licensed MIT. It adds 45 tokens to every session and 1,259 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.

Diagnoses tunnel client/relay problems. Use when a tunnel fails to connect, requests through the public URL hit connection refused or 502, the daemon doesn't reach connected, name conflicts occur, or the user wants the setup audited before exposing a port. Runs tunnel doctor, inspects daemon state, and checks relay…
