Coding-agent prompt

You're working with Azure Functions. Serverless compute on Azure.

Best practices:
- Lean on: first-class .net
- Lean on: consumption pricing
- Lean on: bindings

Things to watch for:
- Watch out for: cold starts
- Watch out for: azure lock-in

General guidance:
- Canonical docs: https://azure.microsoft.com/products/functions — check here before inventing APIs.
- Keep secrets in environment variables, never commit them.
- Write TypeScript where the ecosystem supports it; add types to every exported function.
- Add tests for the critical paths before declaring the task done.
- Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.

Beginner's guide to Azure Functions

In one line: Microsoft's version of AWS Lambda — serverless functions.

You write a small function, Azure runs it whenever it's triggered (HTTP request, timer, queue, etc.). You pay only while it runs.
