Plugins repositories allow users to expand the core capabilities of the Trunk CLI and to share configuration between different repositories.

Importing a plugin repository

By default trunk imports the trunk-io/plugins repository. To import a repo add it to the plugins.sources list. Each repo requires a URI and ref.

    - id: trunk
      ref: v1.2.6


unique identifier for this repository


address used to clone the target repository


commit id or tag to checkout


path to local (on-disk) repository. Takes precedence over uri/ref if defined

import_to_global (default: true)

import content into the global namespace. If set to false actions and linters defined in the plugin must be referenced by <plugin_id>.<name>

Plugin capabilities

Any configuration used in trunk.yaml can also be used in a plugin repository, with some exceptions. A plugin repository must have one root level plugin.yaml and can have any number of other plugin.yaml files in other subdirectories. These configuration files are then merged into one composite plugin configuration.

The most common use for a plugin repository is to define custom linters, actions, or tools. But they can also be used to define a common set of shared tools across an organization. For more info, see organization configs.

The root plugin.yaml file may also have a required_trunk_version field which governs compatibility when upgrading between CLI versions.

Add a plugin to your trunk.yaml file

To add a plugin from GitHub:

trunk plugins add --id=trunk

To add a plugin from GitHub at a specific version:

trunk plugins add v1.2.6 --id=trunk

To add a plugin from a local repository:

trunk plugins add /home/user/self/hello-world --id=hello-world

Plugins scope

Plugins are merged serially, in the order that they are sourced, and can override almost any Trunk configuration. This allows organizations to provide a set of overrides and definitions in one central place.

For instance, you can create your own my-plugins repository with plugin.yaml:

version: 0.1
    - name: trufflehog
        - name: lint
          # override trufflehog to use '--only-verified'
          run: trufflehog filesystem --json --fail --only-verified ${target}
    - ruff@0.0.256

sourced in a .trunk/trunk.yaml file from another repository as follows:

version: 0.1
    - id: trunk
      ref: v1.2.6
    - id: my-plugins
      local: ../my-plugins

When a user runs trunk in the sourcing repository, they will already have ruff enabled, along with the trufflehog override from the my-plugins repository.

Note that private GitHub plugin repositories are not currently supported.

Excluded fields

Plugin sources, as well as the cli version, are not merged from plugin repositories to ensure that config merging occurs in a predictable, stable fashion.
