Auto Assign Action

An action which adds reviewers to the pull request when the pull request is opened.

▶️ Usage

Create a workflow (e.g. .github/workflows/action.yml For more detail, refer to Configuring a workflow) for running the auto-assign action.

name: 'Auto Assign'
on:
  pull_request:
    types: [opened, ready_for_review]

jobs:
  add-reviews:
    runs-on: ubuntu-latest
    steps:
      - uses: kentaro-m/auto-assign-action@v2.0.0
        with:
          configuration-path: '.github/some_name_for_configs.yml' # Only needed if you use something other than .github/auto_assign.yml

Change event that triggers a workflow to the pull_request_target if you want to enable the auto-assign action when opening pull requests from fork repositories or bots like Dependabot.

Using dangerous misuse of the pull_request_target event can be a security risk, so make sure you understand pros and cons before using it.

See below for details:

• Events that trigger workflows / Pull request target - GitHub Docs
• Events that trigger workflows / Pull request events for forked repositories - GitHub Docs

name: 'Auto Assign'
 on:
-  pull_request:
+  pull_request_target:
     types: [opened, ready_for_review]

Create a separate configuration file for the auto-assign action (e.g. .github/auto_assign.yml).
