istio-traffic-management

istio-traffic-management is a skill for Claude Code from wshobson/agents. It costs 40 tokens per session (1,709 once invoked), scanned A, original, MIT.

A guide to managing traffic between services in Istio, a Kubernetes service mesh that controls how applications communicate. It covers routing, load balancing, retries, circuit breakers, and gradual releases such as canary deployments.

In plain words
What is it for?
Use it to route requests, split traffic between application versions, mirror traffic for testing, add retries and circuit breakers, and configure Istio gateways and policies.
Why use it?
It helps teams change or protect service traffic without rewriting each application. It also provides patterns for testing new versions and handling failing services.

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

istio-traffic-management 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 9d 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.

Istio Traffic Management

Comprehensive guide to Istio traffic management for production service mesh deployments.

When to Use This Skill

  • Configuring service-to-service routing
  • Implementing canary or blue-green deployments
  • Setting up circuit breakers and retries
  • Load balancing configuration
  • Traffic mirroring for testing
  • Fault injection for chaos engineering

Core Concepts

1. Traffic Management Resources

Resource Purpose Scope
VirtualService Route traffic to destinations Host-based
DestinationRule Define policies after routing Service-based
Gateway Configure ingress/egress Cluster edge
ServiceEntry Add external services Mesh-wide

2. Traffic Flow

Client → Gateway → VirtualService → DestinationRule → Service
                   (routing)        (policies)        (pods)
