Coloring page

Turn an uploaded photo into a printable black-and-white coloring page.

Security Scan

The skill's instructions require a Gemini API key and a CLI binary (bin/coloring-page) and reference other tooling, but the registry metadata lists no env vars, no binaries, and there is no install spec or code — the package is internally inconsistent.

Purpose & Capability

The stated purpose (convert an uploaded photo to a black-and-white coloring page) is plausible, and needing an image model like Gemini is reasonable — but the skill's metadata (no required env vars, no binaries) does not match SKILL.md which declares GEMINI_API_KEY and references a bin/coloring-page CLI and the 'uv' binary. A user installing this would not get the promised CLI or dependency information from the registry metadata.

Instruction Scope

Runtime instructions tell the agent to run `bin/coloring-page --in <path>` and to use GEMINI_API_KEY (recommended in ~/.clawdbot/.env). The instructions do not request or describe how to obtain that CLI or the underlying 'nano-banana-pro' skill; they do not attempt to read unrelated system files, but they depend on binaries and credentials that are not provided or declared.

Install Mechanism

There is no install spec and no code files, yet the SKILL.md expects an executable (bin/coloring-page) and other tooling. Without an install mechanism or packaged binary, the skill is incomplete and will fail or cause the agent to attempt to run non-existent commands.

Credentials

SKILL.md requires GEMINI_API_KEY (sensitive credential) which is proportionate to using the Gemini image model, but the registry metadata does not declare this requirement. The mismatch is problematic: the skill asks for a sensitive key but the package metadata gives no hint, making it easy to overlook or misconfigure credentials.

Persistence & Privilege

The skill does not request always: true or other elevated persistence. Model invocation is allowed (default) which is expected for usable skills.

What to consider before installing

This skill is incomplete and inconsistent. Before installing or using it, ask the publisher to clarify/provide: (1) an install spec or packaged binary for bin/coloring-page (or change instructions to use available tools), (2) explicit dependency list (uv, nano-banana-pro) and how those are obtained, and (3) confirmation that GEMINI_API_KEY is required and why. Do not supply your GEMINI_API_KEY until you trust the source; if you must test, run the process in a sandbox or use local, auditable tools (ImageMagick/OpenCV) instead. If the author cannot provide an install package or source code, treat the skill as broken/untrusted.

Create a printable black-and-white outline coloring page from a photo.

This skill is designed to be used conversationally:

• You upload an image
• You say: “create a coloring page”
• The assistant runs this skill and sends back the generated PNG

Under the hood, this uses the Nano Banana Pro (Gemini 3 Pro Image) image model.

Requirements

• GEMINI_API_KEY set (recommended in ~/.clawdbot/.env)
• uv available (used by the underlying nano-banana-pro skill)

How the assistant should use this

When a user message includes:

• an attached image (jpg/png/webp)
• and the user asks for a “coloring page”

Run:

• bin/coloring-page --in <path-to-uploaded-image> [--out <output.png>] [--resolution 1K|2K|4K]

Then send the output image back to the user.

CLI

Basic

coloring-page --in photo.jpg

Choose output name

coloring-page --in photo.jpg --out coloring.png

Resolution

coloring-page --in photo.jpg --resolution 2K

Notes

• Input must be a raster image (.jpg, .png, .webp).
• Output is a PNG coloring page on a white background.
