SqlServer.Rules

MCP.Pizza Chef: ErikEJ

T-SQL Analyzer reviews SQL scripts and whole database projects against a large rule library, then reports what it finds: risky patterns, performance traps, and design or naming problems. Connected to GitHub Copilot Chat in VS Code or Visual Studio, you can ask for that review in plain language and get specific feedback back in the chat. Installation is a one-click button in either editor, and no account or key is needed. The same rules can also run automatically whenever a database project is built.
