EDITORIAL TAKEAWAY
Check the instructions and files in one Gem. Keep copies of files that will not transfer, and compare the migrated skill with your usual task.
Before you try it
- Announced September 30. These dates apply to adult personal accounts. Workspace business, enterprise and nonprofit follow in March 2027; education in June 2027.
- Files have a 100 MB total limit. Unsupported types are excluded; over-limit migrations remove the largest files first. Google’s guide lists the affected formats.
- Skills do not yet support some Gem tools, including Canvas and Deep Research. Gems from Google Labs and Opal have a separate shutdown and do not auto-migrate.
A small next step
Our suggested way to explore the change.
- Open a Gem you rely on and inventory its instructions and files.
- Use Google’s guide to identify files that need saving before December 17.
- When the skill appears, run a familiar task and check its output.
