命令参考
图片转换 (ImageMagick)
convert input.png output.webp
convert image.jpg image.png
mogrify -format webp *.png
convert input.jpg -resize 1920x1080 output.jpg
视频/音频转换 (FFmpeg)
ffmpeg -i input.mp4 -vf "fps=10,scale=640:-1" output.gif
ffmpeg -i input.mp4 -c:v libx265 output.mkv
ffmpeg -i video.mp4 -q:a 0 -map a output.mp3
ffmpeg -i input.wav -b:a 320k output.mp3

Usage Guidance
This skill appears to do what it says: run local conversion commands using standard tools. Before installing/using it: (1) verify the author/source (registry metadata and _meta.json owner/version mismatch noted), (2) inspect convert.sh (it invokes binaries on your machine and will create/move files), (3) install conversion tools from official package managers, and (4) avoid converting untrusted files with ImageMagick, LibreOffice, Pandoc or similar tools (these have historically been attack vectors for malicious input). If you need stronger isolation, run conversions inside a sandbox/container or VM and do not grant elevated privileges.
Capability Analysis
Type: OpenClaw Skill
Name: local-file-converter
Version: 1.0.3
The skill is a legitimate file conversion utility that wraps standard command-line tools such as FFmpeg, ImageMagick, LibreOffice, and Pandoc. The `convert.sh` script is well-implemented, utilizing shell case statements to validate output formats and employing proper variable quoting to prevent common shell injection vulnerabilities. No evidence of data exfiltration, persistence mechanisms, or malicious prompt injection was found in the code or documentation.
Capability Assessment
Purpose & Capability
The name/description, SKILL.md and convert.sh consistently implement a local file-conversion capability using ffmpeg, ImageMagick, libreoffice, pandoc and calibre. However, the package source is unknown and _meta.json ownerId/version differ from the registry metadata (minor metadata inconsistency), which is a trust signal to verify the origin.
Instruction Scope
SKILL.md instructs only local conversion actions (detect formats, pick tool, run conversion, return output path). convert.sh only reads the given input file, creates an output directory (or uses OUTPUT_DIR env var), invokes local conversion binaries and reports the result—no attempts to read unrelated files or transmit data externally.
Install Mechanism
This is instruction-only (no install spec). SKILL.md suggests installing common packages via apt or brew (official package managers). No remote downloads or archive extraction are present in the bundle.
Credentials
The skill requires no credentials or special environment variables; convert.sh accepts an optional OUTPUT_DIR environment variable which is reasonable and transparent.
Persistence & Privilege
The skill does not request persistent or elevated privileges (always: false). It does not attempt to modify other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install local-file-converter - After installation, invoke the skill by name or use
/local-file-converter - Provide required inputs per the skill's parameter spec and get structured output
