Why does the included action need to be action.yml?

[mike-potter]

I have an include file within .github/includes/my-action.yml

When using

    steps:
      - includes: my-action

it tries to find .github/includes/actions/my-action/action.yml file, which doesn't exist.

If I try to use:

    steps:
      - includes: .github/includes/my-action

Then it tries to find .github/includes/my-action/action.yml file, which doesn't exist.

If I try to use:

    steps:
      - includes: .github/includes/my-action.yml

Then it tries to find .github/includes/my-action.yml/action.yml file, which doesn't exist.

In all cases, it seems to have this action.yml filename hardcoded somewhere. Would be nice if I could just point to a specific file and not make assumptions about folder structure or file names.
