Is developing-with-streamlit/SKILL.md Recognized as a GitHub Agent Skill?

[hirayukis]

I understand that for GitHub Agent Skills, simply placing a file at .github/skills/SKILL.md does not work, because a dedicated folder (e.g., .github/skills//SKILL.md) is required.

If that understanding is correct, I have another question:
In the official Streamlit GitHub repository, there is a file located at developing-with-streamlit/SKILL.md directly under that directory.

Is that file actually recognized as a GitHub Agent Skill?
