How do I remediate typing-extensions-plus if I installed it?

typing-extensions-plus is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed typing-extensions-plus — how do I know if it already compromised me?

If typing-extensions-plus was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
