Trunk can also be managed by the .trunk/user.yaml file in your repository. This file is optional, but it allows individual developers to customize how they want trunk to run on their machines.
Simply configure .trunk/user.yaml as you would for .trunk/trunk.yaml. Now you can add additional linters, enable actions, or specify default command options, without impacting the way other developers run trunk.
Be mindful that .trunk/user.yaml takes precedence over .trunk/trunk.yaml, so substantial modifications could violate hermeticity.
Trunk also saves a user config in $HOME/.cache/trunk/user.yaml. This is auto-generated in order to manage anonymous usage data and persist login sessions.
