Description
Download videos, audio, subtitles, and clean paragraph-style transcripts from YouTube and any other yt-dlp supported site. Use when asked to “download this video”, “save this clip”, “rip audio”, “get subtitles”, “get transcript”, or to troubleshoot yt-dlp/ffmpeg and formats/playlists.
Usage Guidance
Review this skill carefully before installing. It is suitable only if you trust users and prompts not to supply advanced yt-dlp options after `--`; a safer version would remove raw passthrough or replace it with a small allowlist for benign options like format selection and verbosity.
Capability Analysis
Type: OpenClaw Skill Name: video-transcript-downloader Version: 1.0.0 The skill is classified as suspicious due to its use of `node:child_process.spawn` to execute external binaries (`yt-dlp`, `ffmpeg`) and, critically, its explicit forwarding of arbitrary user-supplied arguments (`opts.extra`) directly to `yt-dlp` in `scripts/vtd.js`. This passthrough mechanism, documented in `SKILL.md`, allows for command injection into `yt-dlp`'s powerful `--exec` option, which could lead to arbitrary code execution if the AI agent is prompted to pass malicious arguments. While this capability is plausibly needed for advanced `yt-dlp` usage, it significantly increases the attack surface for prompt injection against the agent, making it a risky capability without clear malicious intent from the skill itself.
Capability Assessment
⚠ Credentials
Network retrieval and local file writes are expected for this skill, but unrestricted passthrough can override output behavior or invoke yt-dlp features that are not proportionate to routine transcript or download requests.
ℹ Install Mechanism
Installation uses `npm ci` plus optional Homebrew installation of yt-dlp and ffmpeg; this is plausible for the purpose, with one pinned npm dependency in the lockfile.
⚠ Instruction Scope
The SKILL.md examples are mostly task-focused, but lines 63-67 explicitly allow arbitrary extra yt-dlp arguments for transcript fallback, download, audio, subtitles, and formats without an allowlist or warning about sensitive options.
ℹ Persistence & Privilege
The artifacts do not install services, hooks, or persistent background behavior, but dangerous forwarded yt-dlp options could execute local commands with the invoking agent's existing permissions if used.
⚠ Purpose & Capability
Downloading videos, audio, subtitles, and transcripts is coherent with the stated purpose, but the documented raw yt-dlp passthrough after `--` expands the capability beyond media retrieval into any behavior yt-dlp options support.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install video-transcript-downloader
  3. After installation, invoke the skill by name or use /video-transcript-downloader
  4. Provide required inputs per the skill's parameter spec and get structured output
