React & TypeScript linter setup

This skill handles project setup for the company ESLint stack: installing dependencies, adding config files, custom rules, and package.json scripts. For applying and enforcing rules on existing code, use a coding-standards or review skill when available.

When to use this skill

• User wants to install or configure ESLint in a React/TypeScript project.
• User asks to add lint scripts, devDependencies, or ESLint flat config.
• User wants custom rules (e.g. TODO ticket reference) or to migrate to the company config.
• User mentions "setup linter", "eslint config", "lint setup", "add eslint to project".

Prerequisites

• Project has a package.json (npm or yarn).
• Project has a tsconfig.json (or tsconfig.app.json) at the root — required for projectService: true in the config.
• Node.js 18+ (for ESLint 10 and flat config).
