Usage Guidance
This skill appears to implement a Douyin video downloader and mostly matches its description, but it will follow redirects and fetch whatever play_url it finds, then save a file under ~/.openclaw/workspace/douyin-downloads/douyin_last.mp4. Consider these precautions before installing: 1) Only run it in a restricted environment (sandbox or non-production account) because a malicious share URL could cause requests to internal services (SSRF) or arbitrary hosts. 2) Inspect and/or vendor the script locally rather than running unknown code directly. 3) Run as an unprivileged user and ensure network egress controls (block access to sensitive metadata or internal endpoints like 169.254.169.254). 4) Be aware it will overwrite the previous download and store files in your home directory; copy any video you want to keep. If you need higher assurance, ask the author for input validation (restrict hostnames, validate URL patterns) or add size/time limits on downloads.
Capability Analysis
Type: OpenClaw Skill
Name: douyin-video
Version: 1.0.3
The skill is a legitimate Douyin video downloader that parses shared links and saves the video to a local workspace directory. The code in `scripts/douyin.js` uses standard Node.js built-in modules (http/https/fs) to fetch data and manage files, with no evidence of data exfiltration, malicious execution, or prompt injection.
Capability Assessment
Purpose & Capability
Name/description, required binary (node), SKILL.md, and included script align with a Douyin downloader. Minor mismatch: SKILL.md claims 'no environment variables needed', but the script reads HOME to build a path (normal but not declared). Overall capability requested (network fetch + write) is expected for a downloader.
Instruction Scope
The runtime instructions and script accept an arbitrary share URL and perform network requests (follow redirects) and then download the extracted play_url. There is no validation of hostname/URL, so a maliciously-crafted share page or redirect could cause the agent to request internal services (SSRF risk) or arbitrary external hosts. The script writes a fixed file under ~/.openclaw/workspace/douyin-downloads and deletes the previous file (no sandboxing or size limits).
Install Mechanism
Instruction-only skill with no install spec; only requires node to run. No downloads or archive extraction during install, which is low-risk.
Credentials
The skill requests no credentials or env vars. It does read process.env.HOME to construct paths (expected). No other sensitive environment access is requested. Proportional to purpose, but HOME usage should be noted in the README (it currently says '无需配置').
Persistence & Privilege
always:false and no special privileges or persistence. The skill writes files to the user's workspace directory but does not modify other skills or system-wide settings. Autonomous invocation is allowed by default (platform normal) — combine with the network concerns above when deciding to install.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install douyin-video - After installation, invoke the skill by name or use
/douyin-video - Provide required inputs per the skill's parameter spec and get structured output
