Security Scan

This skill's code and instructions match its stated purpose (adding text/logo watermarks to images); it has no network/endpoints or credential requests, though it contains a few non-malicious bugs and portability assumptions you should be aware of.

Purpose & Capability

The name/description (image watermarking, batch processing, position, opacity) align with the included Python scripts. Required binaries and environment variables are none, which is consistent because the tool only needs Python and Pillow. The code operates on local image files and implements the advertised features.

Instruction Scope

SKILL.md and the scripts only instruct local file operations (reading images, writing watermarked outputs). No instructions to collect or transmit external data. Notes: (1) batch mode in watermark.py has a logic bug — the final exit uses result['status'] which doesn't exist for batch responses and will raise an exception; (2) both scripts assume macOS system font paths (PingFang etc.), which may not exist on Linux/Windows and will fall back to default fonts; (3) batch processing will recursively read image files under the provided input directory — make sure you don't point it at sensitive system folders or huge trees.

Install Mechanism

There is no install spec (instruction-only / bundled scripts). That is lower risk: nothing is downloaded or executed automatically beyond the included code. The only declared dependency is Pillow (pip install), which is reasonable for image processing.

Credentials

The skill requests no environment variables, no credentials, and no config paths. This is proportionate for an image watermarking utility that only reads and writes local files.

Persistence & Privilege

The skill is not forced-always, does not request elevated privileges, and does not modify other skills or system configs. Its filesystem writes are limited to the output paths provided by the user/arguments.

Assessment

This skill appears to do exactly what it says: add text or image watermarks to local images and folders, and it does not phone home or require credentials. Before installing/using: (1) ensure Pillow (PIL) is installed; (2) test on a small set of images — batch mode has a bug that can crash the script (exit logic expects a 'status' field that batch responses don't include); (3) adjust font paths or install a suitable TrueType font on non-macOS systems if Chinese text rendering is important; (4) run it only on directories you intend to modify (it will create output files and may overwrite if you choose output paths); and (5) review and run the code locally if you want to be certain it only touches intended files. If you need help patching the batch exit bug or making fonts portable, ask for a small patch recommendation.
