The record

Purpose: TSQLLint describes, identifies, and reports anti-patterns in TSQL scripts.
Auto-fix: The command-line tool can fix problems it identifies as auto-fixable using the --fix or -x option.
Configuration: Users can create a .tsqllintrc configuration file, and the tool uses an in-memory default configuration when none is found.
Rule controls: Rules can be configured as off, warning, or error; violations configured as errors return a non-zero exit code.
SQL compatibility: The configurable SQL Server compatibility levels listed are 80, 90, 100, 110, 120, 130, 140, and 150.
Plugins: Users can extend the tool with custom .NET plugins that implement TSQLLint's IPlugin interface and target net6.0.
SQL placeholders: Before applying lint rules, TSQLLint replaces SQL file placeholders with values supplied through environment variables.
Install methods: The project lists dotnet-tool, Homebrew, and NPM as officially supported installation methods.
VS Code integration: The VS Code extension activates when a .sql file is opened and underlines potential problems for inspection by hovering.
SSMS integration: The project says SQL Server Management Studio can use TSQLLint through its External Tools feature.
Security: The repository lists a security policy, but its security-policy page could not be opened during this research.
License: The software is distributed under the MIT License, which grants permission to use, copy, modify, distribute, sublicense, and sell copies subject to its conditions.
Intended users: The documented use is for people working with TSQL scripts who want to configure and report on undesirable patterns.
Support: The repository provides issue and discussion navigation, but the opened project pages do not state a formal support offering.
