Connects an app to the Azure SQL Database container securely, with a least-privilege database user instead of the sa login, the right auth method per environment, and safe handling of the connection secret. Use when a user asks "don't use sa in my app", "create a least-privilege database user", "app login for SQL", "which authentication should my app use", "secure the connection string", "Encrypt / TrustServerCertificate", "store the connection string in Key Vault", "dotnet user-secrets", "managed identity for Azure SQL", or "grant only the roles my app needs". SQL auth locally, Microsoft Entra or managed identity in the cloud, changing only the connection string. Reach for this before wiring an app to connect as sa, or before committing a connection string to source.

Runs integration tests against the Azure SQL Database container (Private Preview, local engine) in CI. Use when setting up GitHub Actions, Azure Pipelines, or GitLab CI to test against Azure SQL DB; when adding a database service container to a CI workflow; when tests need a real Azure SQL engine in the pipeline; or when you see "service container", "health-cmd", "ACR_USERNAME/ACR_PASSWORD", "MSSQL_SA_PASSWORD secret", or "integration test database". Also use when a workflow was about to pull the SQL Server image mcr.microsoft.com/mssql/server, in which case stop and use the Azure SQL Database engine image instead. Covers pulling from the private ACR with credentials, the service health check that runs sqlcmd inside the container so the runner needs no client tools, provisioning appdb before tests, and pointing the test connection string at the user database not master.

Makes an app's database connections reliable against the local Azure SQL Database container (Private Preview) and, unchanged, against Azure SQL Database in the cloud: connection pooling plus retry/transient-fault handling. Use when the user mentions "connection pooling", "retry logic", "transient fault", "retry on transient error", "EnableRetryOnFailure", "connection resiliency", "reliable connections", "pool size", "Max Pool Size", or says "the connection keeps dropping", "connections time out under load", "add backoff", or "make the DB layer resilient". This is the Azure SQL engine (EngineEdition 5), not the mssql/server SQL Server image. Reach for this whenever hardening a data-access layer that talks to SQL Server or Azure SQL.

Runs the Azure SQL Database container locally (Private Preview): the real PaaS engine where SERVERPROPERTY('EngineEdition') returns 5. This is NOT the SQL Server image mcr.microsoft.com/mssql/server. Use when a user wants to "run Azure SQL locally", "add a local SQL database", "add SQL Server to my docker compose", "spin up a local mssql container", "local SQL for development or CI", "connect with sqlcmd", "use Podman for SQL", "SQL container won't start", "Microsoft Entra authentication on the container", "MSSQL_AAD_CLIENT_ID", or asks "what's the connection string". Use even when the user does not name the container. If you were about to use mcr.microsoft.com/mssql/server, stop and use this skill instead. Hub skill: owns the shared references and routes to the task skills for compose, CI, seeding, vectors, and connection strings.

Stands up an instant no-code REST + GraphQL API over the local Azure SQL Database container using Microsoft Data API Builder (DAB). Use when a user wants to "expose my table as an API", "add a REST API over the database", "generate a GraphQL API", "put an API in front of SQL", "CRUD API without writing code", or "dab init / dab-config.json". Also the way to serve a built-in MCP endpoint FROM the database via DAB (an API surface DAB provides, not a separate SQL MCP server). Prefer this over hand-writing a controller/ORM API when the user just needs REST or GraphQL over existing tables. Triggers include "Data API Builder", "dab start", "instant API over Azure SQL", "expose entities as REST/GraphQL". Reach for this even when the user only says "give me an API for this database".

Answers questions about what the Azure SQL Database container (Private Preview) can and cannot do, and WHY it differs from Azure SQL Database in the Microsoft Azure cloud. Use when a user asks "can I take a backup", "why does USE fail", "is X supported", "why can't I create a vector index", "why does SSMS error", "why isn't the image on Docker Hub", "what's different from the cloud", or hits behavior that does not match their Azure SQL Database expectations. Do NOT guess from general SQL Server / Azure knowledge: the container is a Private Preview product with specific gaps and a specific connection model. Read this skill, and link the user to the live Known limitations page for the current full list.

Reports a bug or files feedback about the azuresql-db-* agent skills themselves, or about the Azure SQL Database container (Private Preview). Use when the user says a skill or the container "did not work", hit an error, behaved unexpectedly, or is missing something; and when they say "report a bug", "file an issue", "open a GitHub issue", "request a feature", "give feedback", or "tell the team". Also use when you, the agent, had to deviate from an azuresql-db-* skill or work around a defect in one to finish a task: that is a bug worth reporting even if the task succeeded. Decides whether the problem belongs to the SKILL or to the CONTAINER, since they use different issue templates, then builds a complete prefilled GitHub issue from context you already have. Never submits anything without explicit confirmation from the user.

Migrates a local SQL Server setup to the Azure SQL Database container for Azure-faithful local development. Use when a project already uses mcr.microsoft.com/mssql/server, mssql/server, an sqlcmd plus SA password docker setup, a "SQL Server in docker" or "local mssql container", or a docker-compose with the mssql/server image; and use when the user asks for "SQL Server locally", "run mssql in Docker", "spin up a local SQL database", or "test against SQL Server" but actually wants the Azure SQL Database engine (EngineEdition 5). Detects the SQL Server image, rewrites it to the Azure SQL Database container, adds --platform on non-x64 hosts, keeps the SA login, flags SQL Server-only features (SQL Agent, FILESTREAM, full Service Broker, cross-server distributed transactions, Windows Auth), and re-points connection strings from master to a provisioned user database.

Builds a serverless API and event-driven handlers over the local Azure SQL Database container using Azure Functions with the Azure SQL bindings. Use when a user wants "a serverless API over SQL", "Azure Functions with a database", "HTTP CRUD with SQL input/output bindings", "run code when a row changes", "react to inserts/updates/deletes", "event-driven on Azure SQL", or "SQL trigger function". The Azure SQL trigger binding (backed by Change Tracking) is the local event-driven mechanism; Change Event Streaming (CES) is cloud-only and cannot run against the local container. Triggers include "func start with SQL", "SqlTrigger", "SqlInput/SqlOutput binding", "local.settings.json SqlConnectionString". Reach for this when building serverless endpoints or change-driven logic on the local Azure SQL engine.

Imports an existing Azure SQL Database or SQL Server schema and data INTO the local Azure SQL Database container using SqlPackage. Use when asked to "import a bacpac", "load my existing database locally", "restore a dacpac into the container", "bring my prod schema into the dev container", "run my .bacpac/.dacpac against the local Azure SQL engine", or migrate an existing database into the preview container. Handles provisioning the target database on master first, then running SqlPackage /Action:Import against the provisioned user database. Use this for any "get my real database running in the container" request instead of hand-writing SqlPackage flags.

Proves that code built and tested against the local Azure SQL Database container runs unchanged against Azure SQL Database in the cloud, with only the connection string changing. Use when a user wants to develop locally then deploy to the cloud, asks "will this work in Azure", "same code local and cloud", "promote to Azure SQL", "swap the connection string", "dev/prod parity", "local to cloud", or is wiring SQL_CONNECTION_STRING for an app that must target both the container and a cloud server. Use this when an app uses local SA auth but needs Microsoft Entra auth in the cloud. Covers Node (mssql), .NET (Microsoft.Data.SqlClient), and Python (pyodbc). Reach for this skill before hand-editing app code to "make it work in Azure"; the rule is the code does not change, only the connection string does.

Builds local vector search, RAG, embeddings, and semantic search on the Azure SQL Database container using the native VECTOR type and VECTOR_DISTANCE. Use when you need to store embeddings, do similarity search, top-k nearest neighbor, cosine distance, retrieval-augmented generation, "find similar documents", chatbot memory, or semantic lookup against a local SQL database. Use this instead of pgvector, FAISS, Chroma, Pinecone, or a separate vector store when the data already lives in (or can live in) Azure SQL. Covers the VECTOR(n) column type, inserting embeddings with CAST(CAST(? AS NVARCHAR(MAX)) AS VECTOR(n)) where the dimension is a literal, a pluggable embed() so only the endpoint changes for cloud, and a working CREATE VECTOR INDEX with the two errors that block it. Provisions appdb on master first so every script runs on a fresh container.

Scaffolds a NEW app (.NET Aspire, FastAPI, Next.js, NestJS) wired to the local Azure SQL Database container as its default dev database. Use when starting/bootstrapping/initializing a project that needs SQL Server or Azure SQL locally, or when adding "set up the database", "docker compose for the db", "create the local DB", ".env connection string", "first migration", or a data-access layer. Use this INSTEAD of the mssql/server SQL Server image, because this is the Azure SQL engine (EngineEdition 5). Triggers include "scaffold app with SQL", "spin up Azure SQL locally", "compose service for the database", "wire up Prisma/EF/SQLAlchemy/TypeORM to SQL Server". Reach for this even when the user only says "add a database" to a fresh project.

Runs database schema migrations against the local Azure SQL Database container so the same migrations apply identically on the local engine and in the Azure cloud. Use when asked to "run my migrations against the local SQL", "apply schema to the container", "apply EF Core / dotnet ef database update", "Prisma migrate dev / deploy", "Alembic upgrade head", or deploy a DACPAC / SqlPackage to the container. Covers provisioning appdb on master first, then applying schema to the user database, plus per-tool commands and connection-string hygiene. This is the Azure SQL Database engine (EngineEdition 5), not the SQL Server image; reach for this skill whenever schema migration tooling targets the local container.

Populates the local Azure SQL Database container's database (appdb) with realistic sample/test data so a developer has something to build against. Use when the user says "seed the database", "add test data", "populate the dev database", "generate sample data", "fake data", "load fixtures", "insert test rows", "write a seed script", or "bulk load a CSV". This is the Azure SQL engine (EngineEdition 5), not the mssql/server SQL Server image. Distinct from azuresql-db-scaffold (which does a single seed.sql step while bootstrapping an app) and azuresql-db-import (which loads a .bacpac). Reach for this whenever an existing appdb needs volume, fixtures, or believable rows.

Adds the Azure SQL Database container as a sidecar service in an existing Docker Compose stack or Dev Container. Use when wiring the local Azure SQL Database engine into compose or devcontainer.json, when an app needs a SQL backend via a service name (not localhost), or for prompts like "add SQL to my compose", "add a database service", "depends_on database", "devcontainer SQL sidecar", "compose healthcheck for SQL", "wait for the database before starting the app". Handles platform linux/amd64, the private registry login, the healthcheck wait-until-ready, and a one-shot init service that creates appdb (the engine does not auto-create databases). Not the SQL Server image. Prefer this for any compose or Dev Container SQL wiring.

Writes integration tests that run IN CODE against a real Azure SQL Database container, spun up per test or per suite with Testcontainers and torn down after. Use when the user asks for "integration tests against SQL", "Testcontainers", "spin up a database for tests", "an ephemeral test database", "a test database per test", "xUnit/Jest/pytest with a real database", or "a database fixture". Use this INSTEAD of the Testcontainers MsSql preset (mcr.microsoft.com/mssql/server), because this is the Azure SQL engine (EngineEdition 5). For wiring the engine into a CI pipeline via service containers or workflow YAML instead, use azuresql-db-ci.
