SmartBundle

Use this skill when adding SmartBundle to a package or repairing its SmartBundle setup.

1. Detect the project's package manager and install smartbundle as a development dependency.
2. Add a package script: "build": "smartbundle build".
3. Configure only the intended exports, files, and bin fields that SmartBundle cannot infer.
4. Install any optional toolchain the project actually uses, following the rules below.
5. Run the build package script.
6. If it fails, fix the configuration, dependency, or source file named by the diagnostic and run the build again.
7. Repeat until the build exits with code 0. A successful build is the installation check; do not try to predict every SmartBundle validation in advance.

Project decisions

• exports defines the package's intended code entrypoints and raw public subpaths.
• files defines non-public static assets that must be copied into the output.
• bin maps public CLI names to source executable entrypoints.

SmartBundle validates the shape of these fields and whether their paths are allowed and exist. It cannot infer the package's intended public API or desired asset set. See docs/package-json.md for details.

Optional toolchain

• TypeScript: install a local development dependency in the range >=5.0.0 <8.0.0. With TypeScript 7, also install @typescript/typescript6. Follow concrete build diagnostics for tsconfig.json; see docs/ts-guide.md when more context is needed.
• Babel: only when the project has a Babel configuration, install @babel/core@^7.26.0 || ^8.0.0 as a development dependency. The project chooses its own configuration, presets, and plugins.
• React: install react in dependencies, optionalDependencies, or peerDependencies, not only in devDependencies, because SmartBundle uses that version to select the classic or automatic JSX transform. For TypeScript projects, add @types/react as a development dependency when needed. See docs/react.md for details.
• Vitest: install vitest@^3.0.0 or vitest@^4.0.0 as a development dependency. In vitest.config.ts, combine await defineViteConfig() from SmartBundle with the project's defineConfig() by using Vitest's mergeConfig().
