WHY THIS HAPPENS (CLEAR DIFFERENCE BETWEEN ENVIRONMENTS)

Firebase Studio currently runs two different Gemini entry points:

🟩 IDX Environment (Code Workspace)

Purpose:

Code editing, refactoring, debugging, incremental improvements.

Gemini behavior:

Acts as a code assistant

Anchors to open files and selections

Does NOT suggest app prototyping

Does NOT show “Prototype this App”

👉 This is the environment you want for Banda.

🟥 AI Environment (AI Studio / App Builder)

Purpose:

App generation, UI design, prototyping, blueprints.

Gemini behavior:

Assumes greenfield or redesign

Tries to create or improve an app

Automatically offers:

App Blueprint

UI stack

Design system

“Prototype this App” button

👉 This environment is hard-wired to prototyping.

No wording can fully disable that behavior.

🧠 THE KEY INSIGHT (THIS IS THE ROOT CAUSE)

The environment decides Gemini’s role before your prompt is read.

So:

In IDX → Gemini = Code Assistant

In AI Environment → Gemini = App Prototyper

Your prompt only influences details, not the mode.

That’s why:

Your same text behaves differently

Safe wording works in IDX

Safe wording fails in AI Environment
