The One-Click Exporter: AI Studio Antigravity, Probed to Its Limits

Short summary

Google's one-click Export to Antigravity feature successfully migrated a multi-agent Firestore app from AI Studio to a local workspace, correctly transferring files and API secrets, but conversation history didn't carry over and the initial deployment exposed a pre-existing Gemini API bug (tool use incompatible with JSON-mode output). Users should locate their project folder manually post-export and test end-to-end before assuming the code works. The export mechanism itself was solid; real troubleshooting time came from undocumented gotchas and generated code bugs, not the migration itself.

• •Export to Antigravity successfully moved files, secrets, and Firestore config from browser to local; conversation history was missing (undocumented regression)
• •Pre-existing Gemini API constraint emerged: tool use + JSON-mode are incompatible; this bug was in generated code, not caused by export
• •Before exporting: verify secrets list. After exporting: locate files manually, test end-to-end, expect to troubleshoot generated code independently
