What is Banana Claude?
Banana Claude is an open-source Claude Code plugin for creating and editing images with Google's Gemini models. It converts plain-language requests into visual briefs and shows the prompt, model, references, data settings, output destination, and nominal estimate before execution. Its workflows include image generation, preservation-aware edits, continued image sessions, and comparisons across prompts and model routes.
The plugin runs locally with Python on Linux or macOS and connects to a billing-enabled Google AI project through a Gemini API key. It includes a bundled MCP server and optional visual architect and critic agents. A standalone skill installation provides direct planning scripts but omits the plugin-managed MCP server, specialist agents, and sensitive key configuration. Native Windows image generation is unsupported; Windows users require WSL.
Paid execution requires approval of the exact plan, with each approval permitting one provider attempt. Images are saved with metadata sidecars, while cost records omit raw prompts by default. Generated results still require review for spelling, geometry, consistency, rights, and production suitability. Local SVG composition can add approved text, fonts, logos, and trusted raster artwork when exact copy matters.
Key capabilities
- Offline planning Builds a visual brief and discloses the prompt, model, references, privacy settings, destination, and nominal estimate before contacting Google.
- Image generation and editing Creates Gemini images and plans targeted changes with explicit requirements for what should remain unchanged.
- Model comparison Compares bounded portfolios of prompts and model routes with an aggregate estimate before execution.
- Approval controls Binds a single-use approval to an exact plan and permits one provider attempt, requiring renewed approval after changes.
- Visual review Supports checks for copy, crop, composition, identity, artifacts, rights, and provenance, with fix or regeneration outcomes.
- Local typesetting Composes approved text, fonts, logos, and trusted raster assets in SVG, with rendered output still requiring review.
Where Banana Claude fits
Banana Claude fits creative workflows conducted in Claude Code, including campaign visuals, covers, product scenes, diagrams, concepts, and social assets. It can support an initial visual direction, a targeted edit to an existing image, or a comparison of alternative prompts and models. Exact legal copy or brand assets can be added locally after the visual field has been generated.
Before deployment, teams need to verify Claude Code and Python requirements, operating-system support, Gemini billing credentials, and provider retention conditions for stored continuation and Search grounding. Nominal estimates are neither complete invoices nor hard spending caps. Existing legacy installations may require a credential scan, cleanup, key rotation, and explicit state migration before the plugin is enabled.
