Explanation

A composite action is definitively identified by the runs.using: composite value in its action.yml metadata file. This setting tells GitHub Actions to treat the action's steps as a sequence of shell commands or other action references rather than a single Docker container or Node.js script. Repository naming (option A), shell scripts in the root (option B), and the presence of a Dockerfile with package.json (option C) are not reliable indicators of a composite action.
