Custom PHPStan Rules: Automate Standards and Save Time
summary
Creates three custom PHPStan rules that run on the AST using nikic/php-parser and PHPStan’s Rule interface, including a route validator (regex-based) that enforces kebab-case URLs and camelCase params, an alert-service upgrade rule that finds calls missing the new type argument, and an extension.neon checker that detects rule classes not registered in the extension file. Implements rules with RuleErrorBuilder, packages them as a PHPStan extension via composer, and reports concrete missing-argument and registration errors during analysis.
