Annotations not recognized in db skills

In Oracle 26ai and 19.28 onwards, its possible to add ANNOTATIONS instead of COMMENTS in tables, columns, views and indexes. However, it seems that there is no skill documentation for this.

In my agent, I had to add this prompt specifically for annotations to be created instead of comments:

Do not use COMMENT ON TABLE / COMMENT ON COLUMN for annotations; use ANNOTATIONS keyword instead. See official documentation for guidance.

Where is a good place to add this context?
