Usage Guidance
Before installing, be aware of these points:
- Privacy/hosting: Despite README claims of 'local-only', the script uploads audio to OpenAI Whisper and sends transcripts/prompts to Anthropic for analysis. If you must keep audio/video entirely offline, do not use this skill as-is (consider replacing Whisper/Anthropic calls with a local ASR/LLM).
- Credential visibility: The code requires OPENAI_API_KEY and an Anthropic API key (used at runtime). The registry metadata did not declare these env vars — verify and set keys only after you accept the external API usage.
- Data sensitivity & copyright: Using yt-dlp downloads remote videos; uploading audio to external APIs may violate privacy or copyright expectations. Only process content you are allowed to upload to those services.
- Confirm author/source: The README points to a GitHub repo and an author handle; if you care about provenance, inspect the repo and commits. Prefer installing from a known repository rather than an anonymous bundle.
- Running safely: Run with the --dry option first to inspect transcripts and outputs. Consider running in an isolated environment (container, VM) and limit network egress if you want to inspect behavior before allowing API calls. Rotate keys after testing and scope them appropriately.
- Ask for fixes: Request the publisher update the registry metadata to declare required env vars (OPENAI_API_KEY, ANTHROPIC_API_KEY) and correct the 'local-only' wording in README/SKILL.md so it accurately reflects external API usage.
If you want a fully offline alternative, ask the author or maintainers whether the tool supports a local-only ASR (e.g., whisper.cpp) and local LLM processing, or consider forking the project and replacing network calls.
Capability Analysis
Type: OpenClaw Skill
Name: youtube-clipper-ko
Version: 0.1.0
The youtube-clipper-ko skill is a legitimate video processing tool designed to automate the creation of short-form clips from YouTube videos. It utilizes standard libraries and tools such as yt-dlp for downloading, OpenAI Whisper for transcription, and Anthropic Claude for content analysis. The Python script (scripts/clip.py) safely handles external process execution using subprocess lists to prevent shell injection, and the instructions in SKILL.md are strictly aligned with the tool's stated purpose without any evidence of malicious prompt injection or data exfiltration.
Capability Assessment
Purpose & Capability
The name/description (YouTube → viral clips using Whisper + Claude + ffmpeg) match the included script: it downloads videos (yt-dlp), extracts audio, calls OpenAI Whisper for transcription, calls Anthropic for segment selection, and uses ffmpeg to produce clips. However the registry metadata lists no required environment variables even though the code expects OPENAI_API_KEY and an Anthropic API key — this metadata omission is an incoherence.
Instruction Scope
SKILL.md and README state '로컬 실행' / '영상 외부 서버에 올라가지 않음', but scripts/clip.py uploads audio to OpenAI's Whisper API and sends transcript/prompts to Anthropic — i.e., user audio and transcript are sent to external services. Instructions also rely on yt-dlp and ffmpeg via subprocess; they do not appear to exfiltrate data to unexpected endpoints beyond OpenAI and Anthropic, but the 'local-only' claim is misleading.
Install Mechanism
There is no binary download/install spec embedded in the package (instruction-only plus included Python script). Dependencies are standard (yt-dlp, ffmpeg, openai, anthropic) and the README/scripting suggest pip/brew/apt installs; nothing in the manifest points to arbitrary archive downloads or obscure URLs.
Credentials
The runtime requires API keys (OPENAI_API_KEY for Whisper and an Anthropic key) which are appropriate for the described external API usage, but the registry metadata incorrectly lists no required env vars and SKILL.md references other tooling keys (TOOLS.md/Gemini) in a confusing way. The omission of these credentials from metadata is a meaningful mismatch and could lead users to miss the fact that audio/transcripts will be uploaded to third parties.
Persistence & Privilege
The skill does not request always:true, does not modify other skills or system-wide configs, and only writes outputs into its own outputs/ directory. It uses subprocesses and writes files locally as expected for a media-processing tool.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install youtube-clipper-ko - After installation, invoke the skill by name or use
