drive SKILL.md doesn't guide agents to use Sheets/Docs APIs for content creation #566
Description
When an AI agent needs to create a Google Sheet, it loads gws-drive and uses drive files create with a Sheets mimeType. This creates an empty file shell because the Drive API can't set cell values, sheet structure, or document content.
The correct approach is sheets spreadsheets create or docs documents create, but nothing in the Drive skill mentions this. Agents pick Drive because it's the first skill that looks relevant for "create a file."
A short note in the Drive skill pointing agents to the service-specific APIs for content creation (Sheets, Docs, Slides) would fix this.
