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 | $0.00168 | $0.01749 |
| Opus 5 | $0.00084 | $0.00874 |
| Sonnet 5 | $0.00034 | $0.00350 |
| Haiku 4.5 | $0.00017 | $0.00175 |
Grade A, and why
azure-network-security-design 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 11d 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.

Azure Network Security Design
Secure Azure networking applies Zero Trust to the network pillar: segment, control traffic explicitly, prefer private connectivity, and inspect / filter egress, assuming the network is hostile. The output is a hub-spoke (or Virtual WAN) topology with NSG microsegmentation, private endpoints, and a single controlled egress path.
When to use
Designing the network topology and controls for an Azure landing zone or workload. Use this skill to pick topology, design segmentation, and place controls.
Do not use this skill for the firewall product itself (azure-firewall), VM hardening
(defender-for-cloud-hardening), or single-service networking (azure-key-vault).
Pick the topology
| Estate shape | Topology | Notes |
|---|---|---|
| Single region, few subscriptions | Hub-spoke (single region) | Default for most |
| Multi-region with many spokes / branch sites | Virtual WAN | Microsoft-managed transit |
| Greenfield enterprise-scale | Azure Landing Zones (CAF) - VWAN or hub-spoke | Use CAF blueprints |
| Heavy on-prem + Azure | Hub-spoke + ExpressRoute / VPN gateway | Hub holds gateway + firewall |
| Small / single-workload | Single VNet, no hub | Don't over-engineer |
Rule of thumb: hub-spoke for most enterprises, Virtual WAN at multi-region branch scale. The hub holds shared services (firewall, gateway, DNS, Bastion); workloads sit in spokes. Don't put workloads in the hub.
Approach
-
Topology and address plan — Pick hub-spoke or Virtual WAN. Allocate non-overlapping RFC 1918 ranges per region / spoke; reserve gateway subnet, firewall subnet, Bastion subnet in the hub. Verify: address plan documented; no overlap with on-prem ranges; no overlap between regions.
-
Segmentation with NSGs and ASGs — NSG at subnet level (preferred over per-NIC). Group workloads with Application Security Groups (ASGs) instead of static IP lists - ASGs survive scale events. Microsegment by tier: web / app / data. Verify: NSG flow logs enabled to a Log Analytics workspace; default-deny rule present; ASGs used instead of IP-based source/dest for VM groups.
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.

azure-network-security-design is a skill published in the GitHub repository vinayaklatthe/microsoft-security-skills (173 stars, last pushed 2mo ago), licensed MIT. It adds 168 tokens to every session and 1,749 once invoked, about $0.0008 per session on Opus 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 2026-08-30.
