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 | $0.00031 | $0.02509 |
| Opus 5 | $0.00015 | $0.01255 |
| Sonnet 5 | $0.00006 | $0.00502 |
| Haiku 4.5 | $0.00003 | $0.00251 |
Grade C, and why
service-mesh scanned grade C with 2 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 8d 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.

Service Mesh
Implement service-to-service communication management with mTLS, traffic shaping, observability, and policy enforcement using Istio or Linkerd.
When to Use
- Securing microservice communication with automatic mTLS.
- Implementing canary deployments, traffic splitting, or A/B testing.
- Adding circuit breakers, retries, and timeouts without changing application code.
- Gaining service-level observability (latency, error rates, request volume).
- Enforcing authorization policies between services.
Prerequisites
- Kubernetes cluster (1.26+) with kubectl configured.
- Helm 3 installed (for some installation methods).
- Sufficient cluster resources (Istio control plane needs ~2 GB RAM).
- For Istio:
istioctlCLI installed. - For Linkerd:
linkerdCLI installed.
Istio Installation
Install with istioctl
# Download istioctl
curl -L https://istio.io/downloadIstio | sh -
cd istio-*
export PATH=$PWD/bin:$PATH
# Install with the production profile
istioctl install --set profile=default -y
# Or use the demo profile (includes all addons, good for learning)
istioctl install --set profile=demo -y
# Verify installation
istioctl verify-install
# Check running components
kubectl get pods -n istio-system
Enable Sidecar Injection
# Enable automatic sidecar injection for a namespace
kubectl label namespace default istio-injection=enabled
# Verify label
kubectl get namespace default --show-labels
# Restart existing pods to inject sidecars
kubectl rollout restart deployment -n default
# Check sidecar status
kubectl get pods -n default -o jsonpath='{range .items[*]}{.metadata.name}{" containers: "}{range .spec.containers[*]}{.name}{" "}{end}{"\n"}{end}'
Install Observability Addons
# Install Kiali, Prometheus, Grafana, Jaeger
kubectl apply -f samples/addons/prometheus.yaml
kubectl apply -f samples/addons/grafana.yaml
kubectl apply -f samples/addons/jaeger.yaml
kubectl apply -f samples/addons/kiali.yaml
# Wait for rollout
kubectl rollout status deployment/kiali -n istio-system
# Access dashboards
istioctl dashboard kiali
istioctl dashboard grafana
istioctl dashboard jaeger
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.

service-mesh is a skill published in the GitHub repository BagelHole/DevOps-Security-Agent-Skills (1,084 stars, last pushed 3mo ago), licensed MIT. It adds 31 tokens to every session and 2,509 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
