For all workflows, the workflow:

[x] Should be contained in a .yml file with the language or platform as its filename, in lower, kebab-cased format (for example, docker-image.yml). Special characters should be removed or replaced with words as appropriate (for example, "dotnet" instead of ".NET").
[x] Should use sentence case for the names of workflows and steps (for example, "Run tests").
[x] Should be named only by the name of the language or platform (for example, "Go", not "Go CI" or "Go Build").
[x] Should include comments in the workflow for any parts that are not obvious or could use clarification.
[x] Should specify least privileged permissions for GITHUB_TOKEN so that the workflow runs successfully.

For CI workflows, the workflow:

[ ] Should be preserved under the ci directory.
[ ] Should include a matching ci/properties/*.properties.json file (for example, ci/properties/docker-publish.properties.json).
[ ] Should run on push to branches: [ $default-branch ] and pull_request to branches: [ $default-branch ].
[ ] Packaging workflows should run on release with types: [ created ].
[ ] Publishing workflows should have a filename that is the name of the language or platform, in lower case, followed by "-publish" (for example, docker-publish.yml).

For Code Scanning workflows, the workflow:

[x] Should be preserved under the code-scanning directory.
[ ] Should include a matching code-scanning/properties/*.properties.json file (for example, code-scanning/properties/codeql.properties.json), with properties set as follows:
