developing-azure-apps-locally is a skill for Claude Code from alexpizarro/azure-lean-stack-skills. It costs 118 tokens per session (1,754 once invoked), scanned A, original, MIT.

A local development setup for running an Azure application offline on a computer. It includes an API, SQL Server database, and blob storage, with Docker-based services and optional mock mode.

In plain words
What is it for?
Use it to start a local stack, test schema changes and migrations, run queries, and develop against local storage before promoting changes to test or production.
Why use it?
It lets developers work on backend, database, and storage code without connecting to Azure or incurring Azure costs.

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

developing-azure-apps-locally 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.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/cors.sh, scripts/migrate.sh, scripts/seed-from-test.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.

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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Developing Azure Apps Locally

Run the whole app on localhost — API + SQL + blob storage — with no dependency on Azure. This is the local "try" tier of the deployment model: local (main) → testproduction.

main is never connected to an Azure environment. You iterate locally against an offline stack, then promote to test (and later production) via the branch-per-environment flow. See orchestrating-azure-deployments Architecture Decision #0.

When to use which local mode

Mode Command Use for
Fully offline (this skill) bash scripts/up.sh then npm start + npm run dev Backend work, schema changes, fast iteration, no Azure cost
Frontend against live test backend cd frontend && npm run dev:test UI-only work that needs real test data; no local API/SQL

Prefer fully-offline for anything touching the API, SQL, or storage.

The offline stack

  • SQL Server 2022 in Docker (mcr.microsoft.com/mssql/server:2022-latest) — the same engine Azure SQL is built on. "Serverless" is an Azure compute tier, not a local concept; the T-SQL engine is identical, so migrations and queries behave the same locally as in Azure.
  • Azurite (mcr.microsoft.com/azure-storage/azurite) — local Azure Blob emulator. Blobs stream from http://127.0.0.1:10000 instead of Azure Storage.

Both run from templates/docker-compose.yml.

Apple Silicon: the SQL Server image is amd64. Enable Docker Desktop → Settings → General → "Use Rosetta for x86/amd64 emulation". (Azure SQL Edge was retired 2025-09 and dropped arm64, so mssql/server under Rosetta is the supported high-fidelity choice.)

Workflow checklist

Copy this into your response and tick items off:

Local dev setup:
- [ ] Step 1: Docker Desktop running (Rosetta enabled on Apple Silicon)
- [ ] Step 2: Copy templates/docker-compose.yml to repo root, templates/local.settings.json.example to api/local.settings.json
- [ ] Step 3: Run scripts/up.sh — starts SQL + Azurite, applies migrations, sets Azurite CORS
- [ ] Step 4: (optional) Run scripts/seed-from-test.sh to copy a small dataset from the test env
- [ ] Step 5: cd api && npm start   (Functions host on http://localhost:7071)
- [ ] Step 6: cd frontend && npm run dev   (Vite on http://localhost:5173, proxies /api → 7071)
- [ ] Step 7: Verify the app loads and a DB-backed page returns data

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.
