Usage Guidance
This skill appears to do what it says and operates on local files. Before installing or running it: 1) ensure your environment has the required tools (ffmpeg, ffprobe, pdftoppm/poppler, whisper-cpp) since metadata does not declare them; 2) expect to download a Whisper model binary from Hugging Face (check license, size, and trust the URL before downloading); 3) scripts operate on files you provide and will write outputs (CSV, ffconcat, MP4) to working directories — review/output paths before running; 4) if you need to run on sensitive audio, note that transcription happens locally if you use whisper-cpp, but if you substitute a cloud ASR you should review that service's privacy; and 5) review the two bundled Python scripts (they are short and readable) if you want full assurance — they do not perform network calls or access unrelated credentials.
Capability Analysis
Type: OpenClaw Skill Name: ppt-audio-to-video Version: 0.1.0 The skill bundle provides a legitimate workflow for converting slide decks (PPTX/PDF) and audio files into narrated videos using standard tools like ffmpeg, pdftoppm, and whisper-cpp. The included Python scripts (extract_slide_outline.py and render_from_timing_csv.py) perform their stated functions safely, using list-based subprocess calls to prevent shell injection and standard libraries for file processing. No evidence of data exfiltration, malicious execution, or harmful prompt injection was found.
Capability Assessment
Purpose & Capability
The skill's name/description match the included scripts and SKILL.md: extracting text from PPTX, producing slide images, transcribing audio, building a timing CSV, and rendering via ffmpeg is expected. One minor inconsistency: the registry metadata lists no required binaries/env vars, but the SKILL.md explicitly requires ffmpeg/ffprobe/pdftoppm and whisper-cpp (and a whisper model). This is reasonable for the task but the metadata omission means the platform won't automatically surface those runtime dependencies.
Instruction Scope
SKILL.md stays on task: it references only slide files, audio files, timing CSVs, local model downloads, and standard tools. The instructions do suggest downloading a model from Hugging Face and using platform-specific exporters (Keynote/PowerPoint/soffice) which are expected for slide rendering; there are no instructions to read unrelated system files or to transmit data to unexpected endpoints beyond the model download URL.
Install Mechanism
This is instruction-only with two small helper scripts; there is no install spec. The SKILL.md suggests installing via brew and downloading a model with curl from Hugging Face — those are normal but are network operations performed at runtime by the user/agent, not packaged installers. No arbitrary or obfuscated remote code downloads are embedded in the skill files.
Credentials
The skill requests no environment variables or credentials. The files and tools it uses (local PPTX/PDF/images/audio, whisper model binary, ffmpeg) are proportional to the stated functionality. There are no requests for API keys, cloud credentials, or unrelated secrets.
Persistence & Privilege
always is false and the skill does not request special persistent privileges or modify other skills/system configs. It runs local scripts and spawns ffmpeg as expected; autonomous invocation is allowed by platform default but is not combined with other red flags here.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install ppt-audio-to-video
  3. After installation, invoke the skill by name or use /ppt-audio-to-video
  4. Provide required inputs per the skill's parameter spec and get structured output
