azure-functions-expert

azure-functions-expert is a skill for Claude Code, Codex from khalilbenaz/claude-skills-collection. It costs 63 tokens per session (2,167 once invoked), scanned A, original, MIT.

A development guide for Azure Functions, Microsoft's serverless platform for running code in response to events without managing servers directly. It covers triggers, bindings, Durable Functions, deployment, and monitoring.

In plain words
What is it for?
Use it to create HTTP or queue-triggered functions, connect functions to Azure services, build long-running workflows, deploy them, and monitor their operation.
Why use it?
It helps choose an Azure hosting plan and structure a Functions project for different traffic, latency, networking, and runtime needs. It also provides setup examples for .NET and Node.js with TypeScript.

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

azure-functions-expert 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.

Azure Functions Expert

1. Choisir le plan d'hébergement

Plan Cold start Timeout max VNET Quand l'utiliser
Consumption Oui (~2-5 s .NET) 10 min Non (outbound via NAT GW) Workloads sporadiques, faible coût
Flex Consumption (2025) Partiel 60 min Oui Remplacement progressif du Premium
Premium (EP1-EP3) Non (pre-warm) Illimité Oui (inbound + outbound) Accès ressources privées, latence critique
Dedicated (App Service) Non Illimité Oui Coexistence avec une App Service existante

Décision rapide : accès à un VNet privé → Flex Consumption ou Premium. Latence < 200 ms en P99 → Premium EP2+. Budget strict, trafic < 1 M invocations/mois → Consumption.

2. Créer et structurer un projet

# .NET 8 isolated worker (modèle recommandé 2026)
func init MyFunctionApp --worker-runtime dotnet-isolated --target-framework net8.0
cd MyFunctionApp
func new --name HttpTriggerExample --template "HTTP trigger" --authlevel anonymous

# Node.js v4 programming model
func init MyApp --worker-runtime node --language typescript --model V4
func new --name QueueProcessor --template "Azure Queue Storage trigger"

# Lancer localement
func start

Structure recommandée .NET :

MyFunctionApp/
├── Program.cs          ← DI + middleware
├── Functions/
│   ├── HttpApi.cs
│   └── QueueProcessor.cs
├── Services/           ← Logique métier injectable
└── local.settings.json ← JAMAIS commité

3. Configurer les triggers et bindings

Règle : déclarer les bindings en attributs, pas de SDK explicite dans la fonction.

// HTTP → Blob output binding (isolated .NET 8)
[Function("ProcessUpload")]
[BlobOutput("output-container/{name}.json", Connection = "AzureWebJobsStorage")]
public string Run(
    [HttpTrigger(AuthorizationLevel.Function, "post")] HttpRequestData req,
    string name,
    FunctionContext context)
{
    var log = context.GetLogger<HttpApi>();
    // Pas d'IBlobClient ici — le binding gère l'écriture
    return JsonSerializer.Serialize(new { name, ts = DateTime.UtcNow });
}

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.
