High-risk skill: the Proton Pass CLI documentation instructs executing remote install scripts (`curl -fsSL https://proton.me/download/pass-cli/install.sh | bash`) and running arbitrary commands with secrets via `pass-cli run`, while managing sensitive env vars like `PROTON_PASS_PASSWORD`. It documents secret storage paths (`~/.ssh/id_ed25519`, `<session-dir>/local.key`) and network endpoints (`https://proton.me/...`, `https://account.proton.me/...`).
