Is the banana skill official?

No. Banana Claude is a community open-source project by Agrici Daniel under an MIT license. Neither Anthropic nor Google ships anything called a banana skill; the name comes from Google's "Nano Banana" nickname for its Gemini image models.

Does it cost money to use?

The skill itself is free, but it only works with a Gemini API key on a billing-enabled Google AI project, and every image request is billed by Google. The skill shows a cost estimate and requires explicit approval before each paid attempt.

Is Banana Claude the same thing as Nano Banana?

No. Nano Banana is Google's name for its Gemini image-generation models (Nano Banana 2 Lite, Nano Banana 2, Nano Banana Pro). Banana Claude is a third-party Claude Code plugin that plans, executes, and reviews requests to those models.

Can I use it in the claude.ai web app?

Not as designed. It is a Claude Code plugin that depends on plugin MCP tools, local Python scripts, and plugin-managed secrets, so the documented install is Claude Code's /plugin marketplace flow, not the claude.ai skill-upload path.

Banana Claude Skill

The banana skill for Claude that this search actually surfaces is Banana Claude, an open-source Claude Code plugin by Agrici Daniel that generates, edits, compares, and reviews images through Google's Gemini "Nano Banana" models. It is not an Anthropic or Google product. The one thing to know before installing: it needs a Gemini API key on a billing-enabled Google AI project, and every generation is a paid Google API call — the skill shows the prompt, model, and a cost estimate, then requires your approval before each attempt. Verified 1 September 2026: 1,010 GitHub stars, MIT license, version 3.0.0, last pushed 30 August 2026. The name is crowded — at least six other community "nano banana" skills exist and none is canonical — but this repo is the top result for the exact query, the most starred, and the most carefully documented of the lot, with an unusually strict approval and key-handling design.

Install

1Prerequisites: Claude Code 2.1.199 or newer, Python 3.11+ with python3 on PATH, and a Gemini API key from a billing-enabled Google AI project.
2In Claude Code, run: /plugin marketplace add AgriciDaniel/banana-claude
3Run: /plugin install banana-claude@banana-claude-marketplace
4Run: /plugin enable banana-claude@banana-claude-marketplace then /reload-plugins — the plugin installs disabled on purpose because generation is a paid service; supply your Gemini key as plugin configuration when prompted, never on the command line.
5Ask for an image, e.g. /banana-claude:banana generate a 16:9 hero with left-side copy space — review the plan it shows, then approve the paid attempt.

What it does

Generate: Turns a plain-language request into a reviewable visual brief and prompt, then routes it across Google's Nano Banana 2 Lite, Nano Banana 2, and Nano Banana Pro models for campaign visuals, covers, product scenes, diagrams, and social assets.
Edit and continue: Makes one clear change to an existing image while protecting identity, geometry, and brand details; iterates via stored Flash or Pro sessions or by attaching the last result as a fresh reference.
Compare (portfolio): Tests up to three prompts across three model routes in one bounded run so you can pick the best result instead of regenerating blind.
Review and typeset: Inspects the actual returned pixels for copy, crop, composition, artifacts, rights, and provenance; adds exact approved text, fonts, and logos locally when spelling matters, rather than trusting the model to render text.
Cost and key control: Plans offline first, shows a nominal cost estimate before any paid request, consumes one single-use 30-minute approval per provider attempt, and keeps API keys out of commands, URLs, metadata, and CI.

Before you install

Unofficial: a community project by one developer, Agrici Daniel — not shipped or endorsed by Anthropic or Google, despite "Claude" in the name.
Paid dependency: requires a Gemini API key on a billing-enabled Google AI project, and every generation, edit, retry, or regeneration is a separately billed Google API call.
The project's own docs warn that older public versions (1.4.1 and 2.1.0) could leave an unpinned third-party MCP entry or a raw Google key in Claude settings or shell history; upgraders are told to run the v3 migration and rotate any exposed key.
The name is ambiguous: at least six other community "nano banana" skills exist (kkoppenhaver, kingbootoshi, intellectronica, feedtailor, chongdashu, and others), so "banana skill" does not refer to one canonical thing.
Approval friction is built in: every paid attempt — including retries — needs a fresh plan and a fresh single-use approval that expires in 30 minutes; deliberate, but slower than one-shot generators.
Young project: created March 2026, so the 1,010 stars reflect roughly six months of history; open issue #9 reports the image cost ledger losing concurrent writes.
Built for Claude Code specifically: it relies on plugin MCP, local Python 3.11+ scripts, and plugin-managed secrets, so it is not a candidate for the claude.ai Settings > Skills upload path.

Facts come from the skill's own repository and docs on the date above, via the GitHub API — not from memory, and never from a sponsor.

Worth comparing

kingbootoshi/nano-banana-2-skill — 408 stars, MIT; a Gemini 3 Pro image CLI that doubles as a Claude Code plugin, with green-screen transparency, reference images, and style transfer — lighter than Banana Claude, last pushed April 2026.
kkoppenhaver/cc-nano-banana — 368 stars, MIT; the simplest of the pack — a plain Claude Code skill that generates images with Nano Banana, without Banana Claude's approval and review machinery.
intellectronica/agent-skills (nano-banana-pro) — 290 stars, CC0; a minimal nano-banana-pro skill inside a mono-repo of agent skills — install from the subdirectory, not the repo root.
