A saved agent configuration is not a completed run.
First agent
Steps
Finish the stored quickstart so a collection has indexed Smart Bites. Open Agent Studio (エージェントスタジオ in Japanese navigation). Use an existing tool that reads that collection. Run it with agent:run. Inspect the output and its citation the same way as search. If the control is absent or the run is rejected, the feature is not available in this workspace. Do not follow an older page that tells you to install an agent SDK.
