Bin field or entry point is correctly configured

A bin field pointing to ./dist/cli.js when no dist/ directory exists is a package that installs successfully and then fails on first invocation with env: node: No such file or directory or Cannot find module. Pointing bin at a .ts file is worse — npx mytool dies with a syntax error on the first import statement. Users uninstall immediately and leave a one-star review. This is the single most common CLI publish-to-npm failure mode.

Set bin in package.json to the compiled JS file, wire a prepublishOnly build script, and include the output directory in files. Verify dist/cli.js exists after npm run build:

{
  "bin": { "mytool": "./dist/cli.js" },
  "files": ["dist"],
  "scripts": {
    "build": "tsc",
    "prepublishOnly": "npm run build"
  }
}
