Set up ESLint, a tool that checks JavaScript for errors and coding rule violations. Configure shared rules, connect checks to editors and automated workflows, and review flagged code alongside its behavior in the browser.
Find TypeScript values that bypass type checking through any, including inferred types and assertions. Suggest unknown, generics that preserve type relationships, or Zod validation for external data, with the checks needed where each value is used.
ESLint is the standard linting tool for JavaScript and TypeScript projects. It statically analyzes your code to find problems, enforce coding conventions, and catch bugs before they reach production. ESLint 9 introduced the flat config format, replacing the legacy `.eslintrc` system with a simpler, more composable `eslint.config.js` file. With a rich plugin ecosystem covering React, TypeScript, accessibility, and import ordering, ESLint is the backbone of code quality in modern web development.

Use ESLint in .NET repositories that ship JavaScript, TypeScript, React, or other Node-based frontend assets. USE FOR: the repo has package.json, eslint.config.*, .eslintrc*, tsconfig.json, or JS/TS/React frontend files; the user asks for JavaScript or TypeScript linting, React rule. DO NOT USE FOR: CSS ownership by itself; route that to stylelint; HTML-only checks on static output; route that to htmlhint. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

Use SonarJS-derived rules in .NET repositories that ship JavaScript or TypeScript frontends and need deeper bug-risk, code-smell, or cognitive-complexity checks than a minimal ESLint baseline. USE FOR: SonarQube, SonarCloud, or eslint-plugin-sonarjs setups; frontend code smells; cognitive complexity and deeper bug-risk rules. DO NOT USE FOR: lightweight base lint setups with no extra smell or complexity rules; teams that reject Sonar tooling. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

各プログラミング言語の既存リンターエコシステムを活用してカスタムlintルールを作成するスキル。 人間向けではなくAIエージェント向けのリンターであり、エラーメッセージはAIに対する修正指示プロンプトとして機能する。 Rust(dylint)、TypeScript/JavaScript(ESLint)、Python(pylint)、Go(golangci-lint)等、 言語ごとの標準的な方法でカスタムルールを `lints/` ディレクトリに作成する。 以下の場合に使用する: (1) プロジェクト固有のコーディングルールをAIに強制させたいとき、 (2) 違反時にAIが読める修正指示を出力するlintルールを作りたいとき、 (3) 命名規則・構造パターン・一貫性ルールをAI駆動のリンティングで強制したいとき。 トリガー: 「リンタールールを作成」「lintルールを追加」「このパターンを強制」 「AIリンター」「カスタムlint」「コードルール」「命名ルール」「構造ルール」 「create a linter rule」「add a lint rule」「enforce this pattern」「AI linter」。
