An AI development platform can change the way a team writes, reviews and releases software. A migration decision therefore needs to examine the working process, the permissions and the exit route alongside the new features.
Google's May 19, 2026 announcement introduced an Antigravity desktop application, a CLI and an SDK. Google's I/O developer announcement.
The accompanying transition notice set June 18, 2026 as the end of Gemini CLI and Code Assist IDE requests under the free individual, Google AI Pro and Ultra access paths. It separately said access through Code Assist Standard and Enterprise licences would remain unchanged, as would Code Assist for GitHub through Google Cloud. Paid Gemini and Gemini Enterprise Agent Platform API-key access also remained available under that notice. Establish the actual access path before deciding whether the change requires a migration. Google's transition notice.
The useful product question is specific: can this team adopt the platform while retaining control of its work, costs and release decisions?
Map the dependency before changing the workflow
Record where the platform sits in the development process. Does it generate suggestions, edit a repository, run tests, manage credentials, deploy an application or operate an external account? Those are different authorities and need separate boundaries.
Keep the development assistant's authority separate from the authority of the product being built. A coding tool's ability to edit a robotics project does not give it permission to control the deployed equipment. Similarly, an integration being technically available does not establish permission to use every connected service operation.
Test a representative task
Choose a bounded task from existing work and define acceptance before the trial. Include the review effort, failed attempts and manual recovery in the result. Retain the original repository and a reproducible way to perform the task without the new tool.
Check the parts of the workflow that are easy to overlook in a demonstration:
- Whether the intended files, project configuration and build outputs remain intact.
- Whether credentials and external-write permissions stay within the approved scope.
- Whether tests and approvals run through the team's existing release path.
- Whether work can be resumed after a limit, interruption or model change.
- Whether another team member can inspect the changes and continue the task.
A faster first draft is useful only when the accepted result and the total delivery effort justify the change.
Separate commercial terms from capability claims
Google also announced subscription and usage changes in May 2026. Treat that announcement as a dated reference, then verify the actual account's current plan, region, limits and contractual terms before making a purchase or capacity commitment. Google's subscription announcement.
Estimate cost using representative completed work and the team's observed usage. Keep list prices, promotional offers, entitlements and measured consumption distinct. A subscription label alone does not establish predictable capacity for a particular workflow.
Make the exit route practical
Identify the assets that must remain portable: source code, tests, project instructions, dependency locks, required records and operating knowledge. Determine which features depend on the supplier and what would need to be replaced if access ended.
Test that exit route on the same bounded task. An export button is not sufficient evidence that the team can build, verify and maintain the result elsewhere. Record the remaining work and its owner.
Decide from the trial
The decision can be adopt for a defined use, extend the evaluation, retain the current workflow or decline the migration. Record the evidence, the constraints and the event that would trigger another review.
A Product Decision Review can examine a consequential model or architecture choice when supplier capability, operating control and product economics point in different directions. The objective is a reviewable commitment with clear limits.
