Teaching Claude Code to Paint: A Stateful Image-Editing Skill Built on Gemini's Interactions API and MCP

The nb2lite-skill integrates Google's gemini-3.1-flash-lite-image model into a FastMCP server, creating a skill for Claude Code and Kiro. Unlike traditional stateless image-generation workflows, this tool allows for stateful editing. Users can generate an initial image, such as a cyberpunk kitchen, and subsequently modify it by adding specific elements, like a neon RAMEN sign, without re-prompting the entire scene. This capability enables seamless iterative adjustments to images through the Gemini Interactions API and MCP.
