Catches bugs, security issues, and style violations before they hit production by running linters, formatters, and security scanners on your code. You'll want this when setting up CI/CD pipelines, pre-commit hooks, or enforcing team coding standards. The skill covers ESLint for JavaScript/TypeScript, pylint and mypy for Python, plus SonarQube integration and custom AST analysis. The honest take: static analysis tools can feel annoying at first, especially if you configure them too strictly out of the gate, but they save massive debugging time once your team commits to actually fixing the issues instead of just suppressing warnings. Start with reasonable rules and tighten gradually.
