Notes & disambiguation
- Officially renamed from Agent Designer to Workflow Builder upon reaching General Availability (GA) on September 3, 2026; the legacy documentation URL (docs.cloud.google.com/gemini/enterprise/docs/agent-designer) redirects directly to docs.cloud.google.com/gemini/enterprise/docs/workflow-builder (though some certification exam questions still reference 'Agent Designer').
- Originally launched in Private Preview on April 9, 2025 (Google Cloud Next '25) for building simple prompt-based chat agents, then expanded with a visual Flow canvas (November 19, 2025) and scheduled triggers (December 19, 2025)—leading to the 'Workflow Builder' rename at GA because it creates both conversational Chat agents (@-mentionable) and multi-step deterministic/non-deterministic Workflows.
- Not merged with Agent Studio: Workflow Builder lives inside the end-user Gemini Enterprise web app (enabled by an admin via the 'Enable Workflow Builder' toggle on discoveryengine.googleapis.com, with no code export), whereas Agent Studio lives in the Google Cloud Console (aiplatform.googleapis.com, where its canvas URL happens to use /agent-platform/studio/agent-designer) for developers exporting Python ADK code and deploying to Agent Runtime.
