What is azure-functions?

A guide to Azure Functions, Microsoft's service for running code without managing servers, in response to triggers such as HTTP requests, messages, schedules, or files.

Use it for APIs, webhooks, scheduled jobs, queue workflows, file processing, real-time data, backend logic, and Azure service integrations.

It reduces infrastructure work for event-driven applications and includes ways to connect services, authenticate requests, and monitor execution.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00602
Opus 5.5	$0.00011	$0.00241
Sonnet 5.5	$0.00006	$0.00120
Haiku 4.5	$0.00003	$0.00060

Security

Grade C, and why

azure-functions scanned grade C with 2 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-config.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Overview

Azure Functions enables serverless computing on Microsoft Azure. Build event-driven applications with automatic scaling, flexible bindings to various Azure services, and integrated monitoring through Application Insights.

When to Use

HTTP APIs and webhooks
Message-driven processing (Service Bus, Event Hub)
Scheduled jobs and CRON expressions
File and blob processing
Queue-based workflows
Real-time data processing
Microservices and backend logic
Integration with Azure ecosystem services

Quick Start

Minimal working example:

# Install Azure Functions Core Tools
curl https://aka.ms/install-artifacts-ubuntu.sh | bash

# Login to Azure
az login

# Create resource group
az group create --name myapp-rg --location eastus

# Create storage account (required for Functions)
az storage account create \
  --name myappstore \
  --location eastus \
  --resource-group myapp-rg \
  --sku Standard_LRS

# Create Function App
az functionapp create \
  --resource-group myapp-rg \
  --consumption-plan-location eastus \
  --runtime node \
  --runtime-version 18 \
  --functions-version 4 \
  --name myapp-function \
  --storage-account myappstore
// ... (see reference guides for full implementation)

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-functions is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (376 stars, last pushed 8mo ago), licensed MIT. It adds 28 tokens to every session and 602 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
