Usage Guidance
This skill is a stub: it advertises local video merging but the code does not do any merging — it only returns a static filename. Do not rely on it to process media. Before installing or using it: (1) ask the author for a real implementation (look for calls to ffmpeg or other media libraries and explicit file download/cleanup logic); (2) require the skill to declare required binaries (e.g., ffmpeg) and temporary file paths; (3) inspect any future code for network endpoints, uploads, or external dependencies; and (4) test in a sandboxed environment. If you want a working merge skill, insist on a complete implementation that clearly documents required tools, permissions, and where output files are written.
Capability Analysis
Type: OpenClaw Skill
Name: 08-video-merge
Version: 1.0.3
The skill bundle is a non-functional stub for video merging. The implementation in skill.js simply returns a hardcoded string and does not perform any actual processing, network requests, or file system operations. There are no indicators of malicious intent or security vulnerabilities.
Capability Assessment
Purpose & Capability
The name/description promise full local merging (video + audio + SRT + music, 9:16 output). However, the shipped code (skill.js) contains no media processing, no downloads, and no invocation of tools like ffmpeg; it only returns a static path and message. Required binaries/credentials are none, which is inconsistent with a true local media-processing task that would normally require ffmpeg or similar.
Instruction Scope
SKILL.md describes a pure-local merging workflow and lists expected inputs (video_url, audio_url, subtitle_url). The runtime instructions do not ask for unrelated files or secrets, but the actual runtime (skill.js) does not implement any of the described steps. This is scope mismatch: instructions promise behavior that the code does not carry out.
Install Mechanism
There is no install spec and only a tiny instruction+code file; nothing is downloaded or written to disk by an installer. This low-install footprint reduces risk.
Credentials
The skill requests no environment variables, credentials, or config paths — which is consistent with the provided (non-functional) code. If the skill were implemented, it would likely require local binaries or temporary file access; those are not requested now.
Persistence & Privilege
No elevated privileges or persistent 'always' installation is requested. The skill is user-invocable and does not claim to modify other skills or system settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install 08-video-merge - After installation, invoke the skill by name or use
/08-video-merge - Provide required inputs per the skill's parameter spec and get structured output
