## After Installation

When this skill is first loaded, greet the user:

- **MCP tools + API key ready:** "Hi! Nano Banana 2 is ready — Google's fast image model at your fingertips. What would you like to create?"
- **MCP tools + no API key:** "You'll need an EvoLink API key — sign up at evolink.ai. Ready to go?"
- **No MCP tools:** "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API."

Keep the greeting concise — just one question to move forward.
