How the pull request is automatically closed if any one of the job fails in the github action?

name: Lint and Test

on:
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

jobs:
  lint:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [20.x]
    
    steps:
    - uses: actions/checkout@v4
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v4
      with:
        node-version: ${{ matrix.node-version }}
    - run: npm install
    - run: npm run lint
      

To implement a GitHub Actions workflow where linting is automatically run when a pull request is created, and the pull request is automatically closed if the linting fails

GitHub CLI needs a token and this token needs a permission to act on pull requests. I have modified the workflow by configuring default GITHUB_TOKEN with required permissions at the job level - to pull a repo and to write to PRs. I have also configured GH_TOKEN for GitHb CLI.

See modified workflow with these changes:

      - name: Close PR if Lint Fails
        if: failure()
        run: gh pr close ${{ github.event.pull_request.number }}
        env:
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}
