Static analysis tools, or linters, are awesome tools for catching bugs and finding code smells in your project. Instead of looking at what values things have at run time or what the types of these values are, this tool looks at how the code is written. This particular angle gives it a special position to report specific problems and, by the same occasion, grant unique kinds of guarantees. The most useful linters provide the ability to create custom rules, enabling developers to find code that your team has agreed not to write, or create guarantees about parts of the code that would not be possible to get through other means like API design or testing.

In this presentation, we will look at why linters hold a unique position in our tooling and why you should be writing custom rules for your projects. We will learn how a linter works (not necessarily your favorite one) and how rules are written. Lastly, we will explain when this tool is appropriate and when it is inappropriate, and how to keep you and your teammates from being frustrated by linters.
