[gotcha] Why does my npm script run from the package root instead of the current working directory, and how do I find where npm was invoked?

npm scripts always execute from the package root \(where package.json lives\), regardless of the shell's current directory. Use the INIT\_CWD environment variable to access the directory from which the user ran npm. Do not assume process.cwd\(\) or relative paths reflect the invocation directory.

Journey Context:
npm run prepends node\_modules/.bin to PATH and runs scripts from the package folder. This is usually what you want for monorepos and consistent builds, but it breaks scripts that need to operate on files relative to the user's shell location. INIT\_CWD is the officially documented escape hatch. A common mistake is writing file-watcher or scaffolding scripts that use process.cwd\(\) and then fail when invoked from a subdirectory. For lifecycle scripts such as postinstall, be aware the same rule applies and the working directory is the installed package root, not the project root.
