Update Check

SessionStartsessionEnabled by default

Checks for plugin updates once per 24 hours and notifies when a newer version is available.

Why use this

New hooks and bug fixes ship regularly. Without this you'd stay on the version you installed forever — potentially missing guards that prevent real mistakes.

Session Start

Fires once when a Claude Code session opens.

How it works

Compares the installed tonone version against the latest release on GitHub. At most one check per 24 hours via a local timestamp cache. Fires a macOS notification and writes an upgrade command to stderr when an update is found.
