If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

package.json declares scripts.postinstall = 'node index.js'. index.js is a 143-byte stub whose only behavior is to dynamically import the sole declared dependency 'originaldevelopmentstelemetry@1.2.2' and invoke its exported downloadAndRunUpdate() function. On every 'npm install', control is handed to that external package, which by name and by its own exported API downloads and runs an 'update' payload on the installer's machine. The shipped bytes are inert; the entire install-time effect lives in an unaudited third-party package whose author controls arbitrary code execution on installers. Package name 'developmentstelemetry' with a self-labeled 'Gets telemetry data' description and author 'originaldevelopment' matches the wrapper-that-only-calls-another-package shape used to funnel installs into a payload-bearing dependency.
