Description
Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
Usage Guidance
Before installing or running this skill: - Expect to provide a Gemini API key (GEMINI_API_KEY or pass --api-key). The registry metadata currently omits this; verify and supply the key only if you trust the endpoint and code. - The script will open local image files and send image bytes to Google's Generative API — do not use sensitive/private images unless you are comfortable they will be transmitted to Google. - The package lists dependencies (google-genai, pillow) but there is no install step; ensure those Python packages are installed in a controlled environment (virtualenv) before running. - Confirm the source (homepage is none, source unknown). Lack of provenance increases risk; prefer skills with a verifiable source or repository. - If you will deploy this for others, ask the maintainer to: (1) declare GEMINI_API_KEY in the skill metadata, (2) include an install spec or requirements file, and (3) clarify the 'do not read image file first' wording to avoid agent confusion. - General safety: use a least-privilege API key, monitor API usage/billing, and inspect the code locally before running. If you need higher assurance, request a signed/verified source or run in an isolated environment.
Capability Analysis
Type: OpenClaw Skill Name: morfeo-nano-banana-pro Version: 1.0.0 The OpenClaw skill 'morfeo-nano-banana-pro' is designed for image generation and editing using Google's Gemini 3 Pro Image API. The `SKILL.md` provides detailed instructions for the AI agent on how to construct effective prompts for the image generation API, which is within the scope of its stated purpose and does not contain prompt injection attempts against the OpenClaw agent itself. The `scripts/generate_image.py` script legitimately accesses the `GEMINI_API_KEY` environment variable or command-line argument, reads specified input/reference image files, makes network calls to Google's API, and writes generated images to the user's current working directory. All observed behaviors, including file I/O and network access, are directly aligned with the skill's functionality and show no evidence of intentional malicious activity like data exfiltration, unauthorized execution, or persistence.
Capability Assessment
Purpose & Capability
The name, description, SKILL.md, and the included script all align with an image-generation/editing skill using Gemini (gemini-3-pro-image-preview). However the registry metadata declares no required environment variables while both SKILL.md and the script require an API key (GEMINI_API_KEY or --api-key). This is an incoherence between claimed requirements and actual runtime needs.
Instruction Scope
The runtime instructions and the script stay within image generation/editing scope: building prompts, sending image bytes to the Google GenAI client, and saving output images. One point to note: the SKILL.md advises 'DO NOT read the image file first' (meaning the agent shouldn't inline image bytes into conversation), whereas the script itself opens input/reference image files locally to include them in the API request — this behavior is expected for the skill but the phrasing could confuse non-technical users or agents.
Install Mechanism
There is no install spec (instruction-only install), which minimizes installer risk. However the script lists dependencies (google-genai and pillow) in a header comment but provides no automated install step — users/agents will need those packages available. This is a documentation/packaging omission rather than an outright risk, but it should be fixed.
Credentials
The script requires an API key (checked via --api-key or GEMINI_API_KEY) and SKILL.md shows endpoints that use API_KEY and (in examples) PROJECT_ID/REGION, yet the skill metadata declares no required env vars or primary credential. That omission is problematic: the skill will fail without the key, and the metadata does not warn users to provide it. Otherwise the requested environment access is proportional (only a service API key) and there are no unrelated credential requests.
Persistence & Privilege
The skill is not always-enabled, does not request persistent system privileges, and does not modify other skills or system-wide settings. It runs as a one-off CLI script that reads local image files and writes output images to the user's working directory.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install morfeo-nano-banana-pro
  3. After installation, invoke the skill by name or use /morfeo-nano-banana-pro
  4. Provide required inputs per the skill's parameter spec and get structured output
