      build:
        description: |
          Build parameters. Must be a string or a JSON object.
          For string, provide a list of commands to run during the build step, one per line.
          For JSON object, provide the following properties:

          - `commands`: Array of commands to run during the build step.
          - `env`: Object of environment variables to set during the build step.
          - `artifact`: String or array of strings specifying paths to artifacts to upload after the build

          Example:
          ```json
          {
            "commands": [
              "build",
              "generate-artifacts"

      lint:
        description: |

          Accepts a JSON object for lint options. See [lint action](../../actions/lint/README.md).
          It should generate lint reports in standard formats.

          Example:

          ```json:package.json
          {
            "lint:ci": "eslint . --output-file eslint-report.json --format json"

          Set to `null` or empty to disable.
          Accepts a JSON object for test options. See [test action](../../actions/test/README.md).
          If coverage is enabled, it should generate test and coverage reports in standard formats.

          Example:

          ```json:package.json
          {
            "test:ci": "vitest run --reporter=default --reporter=junit --outputFile=junit.xml --coverage.enabled --coverage.reporter=lcov --coverage.reporter=text"

            "image": "node:18",
            "env": {
              "NODE_ENV": "production"
            },
            "options": "--cpus 2",
            "ports": [8080, 3000],
            "volumes": ["/tmp:/tmp", "/cache:/cache"],
            "credentials": {

          - `pathMapping` (object) path mapping from container paths to repository paths. Defaults is working directory is mapped with repository root.

          See https://docs.github.com/en/actions/how-tos/write-workflows/choose-where-workflows-run/run-jobs-in-a-container.

          When specified, steps will execute inside this container instead of checking out code.
          The container should have the project code and dependencies pre-installed.
