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 | $0.00040 | $0.01774 |
| Opus 5 | $0.00020 | $0.00887 |
| Sonnet 5 | $0.00008 | $0.00355 |
| Haiku 4.5 | $0.00004 | $0.00177 |
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 12d 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.
This is a copy
88% identical to istio-traffic-management — 27 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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)

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.

istio-traffic-management is a skill published in the GitHub repository CGSOG-JumpStarts/JumpStart-AutoNav (10 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 1,774 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to istio-traffic-management, differing in 27 lines, and is treated as a copy.
