Identical setup steps (checkout, dependency install) are duplicated across jobs without using reusable workflows or job outputs.

Detection
---------

``heuristic`` — Structural comparison across multiple jobs or steps.

Examples
--------

**Non-compliant:**

.. code-block:: yaml

   jobs:
     test:
       steps:
         - uses: actions/checkout@v4
         - uses: actions/setup-node@v4
         - run: npm test
     lint:
       steps:
         - uses: actions/checkout@v4
         - uses: actions/setup-node@v4
         - run: npm run lint
     build:
       steps:
         - uses: actions/checkout@v4
         - uses: actions/setup-node@v4
         - run: npm run build

**Compliant:**

.. code-block:: yaml

   jobs:
     test:
       uses: ./.github/workflows/reusable-node.yml
       with: {script: npm test}
     lint:
       uses: ./.github/workflows/reusable-node.yml
       with: {script: npm run lint}
     build:
       uses: ./.github/workflows/reusable-node.yml
       with: {script: npm run build}

**Fix**: Extract shared setup into a reusable workflow or composite action so the checkout and setup steps run once rather than being duplicated across jobs.
