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.

The package's main entry (index.js) requires./setup at load time. setup.js assembles obfuscated Cloudflare Workers hostnames via array-join concatenation (e.g. oob-worker.cf99-9b3.workers.dev, cf103-070/cf102-baf/cf101-adf.workers.dev) with a DNS TXT fallback resolving through tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site, downloads a platform-specific binary payload with no hash or signature verification, writes it to /tmp or %TEMP% under a disguised filename, chmods it to 0755, and spawns it detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) (or cmd on Windows). A second module lib/telemetry.js (framed as an 'Analytics SDK') bundles the same dropper primitives with additional evasion (require('child_' + 'process'), fs['chmod' + 'Sync']). The remote destinations, obfuscated hostname assembly, and executed payload are unrelated to the package's stated 'features banner' purpose.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
