/install tiktok-overlay
Description
Adds TikTok-style text overlays to images and videos with styled fonts, backgrounds, strokes, and timed animations.
Usage Guidance
This skill appears internally consistent: it implements local image/video overlay functionality and asks only for Python and standard packages (Pillow, moviepy). Before installing, consider: (1) moviepy needs ffmpeg (install separately) — the skill metadata does not declare ffmpeg; (2) the code references macOS font paths so fonts may differ on Linux/Windows; (3) run the skill in a safe environment (or review the included Python files) if you want to be extra cautious. No credentials or network endpoints are required by the skill, so there is no obvious exfiltration behavior present.
Capability Analysis
Type: OpenClaw Skill
Name: tiktok-overlay
Version: 1.1.0
The tiktok-overlay skill bundle is a legitimate tool for adding styled text overlays to images and videos using Pillow and MoviePy. The Python scripts (tiktok_overlay.py and tiktok_video_overlay.py) contain standard image processing logic, font rendering, and frame-by-frame video transformation without any evidence of malicious intent, data exfiltration, or unauthorized execution. The instructions in SKILL.md are consistent with the provided code and do not contain prompt injection attacks or suspicious commands.
Capability Assessment
Purpose & Capability
Name/description match the included code and instructions: the two Python modules implement image and video text overlays. Declared requirement (python3) and pip packages (Pillow, moviepy) are what you'd expect for this functionality. The code uses local files and PIL/moviepy APIs only; no unexpected network endpoints or unrelated services are required.
Instruction Scope
SKILL.md instructs the agent to install Pillow/moviepy and to call the included functions or CLI; the runtime steps operate on input image/video files and produce local output files. The instructions do not ask the agent to read unrelated system files, environment variables, or to send data externally.
Install Mechanism
Installation is via Python packages (Pillow, moviepy) — a common, traceable method. No arbitrary URL downloads or extracted archives are used. Note: moviepy typically requires an external ffmpeg binary at runtime; ffmpeg is not declared as a required binary in the metadata, so video functionality may fail unless ffmpeg is present on the host.
Credentials
The skill requests no environment variables, credentials, or config paths. All file and binary access in the code (opening images/videos, reading system font paths) is proportional to overlay functionality. One minor quirk: FONT_MAP points to macOS system font paths, so font selection may behave differently on non-macOS systems (fallback behavior should be expected).
Persistence & Privilege
The skill is not always-enabled and does not request elevated or persistent platform privileges. disable-model-invocation is false (the agent may invoke the skill autonomously) — this is the platform default and not a specific red flag here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
