- New information regarding the transition to “Skills” accompanying the discontinuation of “Gems.”
- App file analysis of the Android version of the “Google” app v17.52.14 update has confirmed the addition of new resource codes related to the rollout of “Skills (robin_customize_skills)” as an extension for “Gemini.”
- Possibility that “Skills” will be rolled out and integrated not only into “Gemini Spark” but also into “Gemini.”
Recently, we reported that information regarding the discontinuation of “Gem (Gems)”—the custom AI expert feature deployed in the Google AI “Gemini” app—was found within the Android version of the “Gemini” app.
This indicated that users would be prompted either to save their “Gem” prompts for secondary use or to reuse (migrate) them as custom instructions for “Skills.” Regardless, this discontinuation news comes as a major shock to heavy “Gem” users.

In other words, if “Gems,” which are also available to free users, are discontinued, there was a possibility that free users (who do not have access to “Gemini Spark”) and “Google AI Plus” members would be left unable to use “Skills,” effectively hitting a dead end. New information has been obtained regarding this matter, and we are sharing it through our original app file analysis report content on Jetstream, “App Teardown.”

As a result of analyzing the app files from the Android “Google” app v17.52.14 update released on Monday, August 17, 2026, we confirmed that new resource codes related to the rollout of “Skills (robin_customize_skills)” as a “Gemini” extension have been added. This strongly suggests that “Skills” will likely be expanded and integrated not only into “Gemini Spark” but also into “Gemini.”

It seems safe to assume simply that “Gems” will be replaced by “Skills.”
Furthermore, “Skills” in “Gemini” appear to function as a marketplace-style service where users can install publicly available extensions into “Gemini” much like installing apps on Android or iOS devices, adding new capabilities. As a result, extensibility is expected to be even greater than that of “Gems.”
