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 | $0.00145 | $0.01808 |
| Opus 5 | $0.00072 | $0.00904 |
| Sonnet 5 | $0.00029 | $0.00362 |
| Haiku 4.5 | $0.00015 | $0.00181 |
Grade A, and why
azure-app-service-security 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.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Azure App Service Security
Azure App Service hosts web apps and APIs as a managed PaaS. Securing it means eliminating secrets in config, removing public exposure where possible, enforcing modern transport, and fronting it with a WAF when it has to be public.
When to use
Hardening web apps and APIs hosted on Azure App Service. Use this skill to plan identity, network, secrets, and transport posture for a Web App / API App.
Do not use this skill for Azure Functions only (similar but separate platform), AKS workloads, or VM-hosted web apps.
Pick the configuration by exposure pattern
| Exposure | Inbound | Outbound | Front-end |
|---|---|---|---|
| Internal-only app (intranet, API for VNet workloads) | Private endpoint, public access disabled | VNet integration to spoke | Internal Application Gateway |
| Public web app, sensitive data | Public + access restrictions to WAF only | VNet integration | Front Door or App Gateway with WAF, Prevention mode |
| Public web app, basic | Public, default | None / VNet integration | App Gateway with WAF |
| API consumed by partners | Private endpoint + APIM in front | VNet integration | APIM (with WAF on APIM if public) |
| Background worker / no inbound | Public access disabled | VNet integration | None |
Rule of thumb: if it doesn't need to be on the internet, use a private endpoint and disable public network access. If it does need to be on the internet, put Front Door / App Gateway with WAF in Prevention mode in front and restrict the app to accept traffic only from the WAF's IP range or service tag.
Approach
- Enable managed identity — System-assigned managed identity by default. Grant it
least-privilege roles on Azure SQL (
SQL DB Contributoris wrong - use AAD auth + contained user), Storage (Storage Blob Data Reader), Key Vault (Key Vault Secrets User). Verify: app has managed identity; no SQL / Storage connection strings with embedded passwords in config.
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-app-service-security is a skill published in the GitHub repository vinayaklatthe/microsoft-security-skills (173 stars, last pushed 2mo ago), licensed MIT. It adds 145 tokens to every session and 1,808 once invoked, about $0.0007 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.
