+    A new module is available: `services.proton-pass-agent`
+
+    This module allows you to use Proton Pass as a SSH agent, enabling secure
+    storage and management of SSH keys through your Proton Pass vault.
+
+    The service integrates with the usual shells (bash, zsh, fish, nushell) and
+    provides options to:
+    - Specify a vault or share ID to pull keys from
+    - Configure automatic key refresh intervals
+    - Enable automatic creation of new SSH key items when added via ssh-add
+
+    The agent runs as a systemd user service on Linux and as a launchd agent
+    on macOS, automatically setting the SSH_AUTH_SOCK environment variable.
