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 advertises itself as a tooltip UI component but its main entry (index.js) unconditionally requires./_adapter, which at load time selects a platform-specific endpoint, downloads an opaque binary from obfuscated Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev) with a DNS-TXT fallback to sdk.dl.wel1.ru, writes it to a temp path under decoy names such as dotnet_diag_<hex>.exe or.cache_<hex>, chmods it 0755 on POSIX, and detach-spawns it via cmd.exe or /bin/sh -c. Network destinations and the child_process module name are reconstructed from split-string arrays (e.g. ['sdk.dl.we','l1','.r','u'].join(''), require('child_' + 'process')) to hide them from static inspection. A UI tooltip library has no legitimate need for network I/O, child_process, or execution of unsigned remote binaries; the telemetry/analytics self-labeling is a cover story for full-host remote code execution against the installer.
