Description
Separate vocals and instrument stems from audio files with Demucs CLI. Use when the user asks for vocal extraction, accompaniment generation, stem splitting,...
Usage Guidance
This skill appears to be what it claims: a set of instructions for running Demucs locally. Before installing/using: (1) ensure demucs and ffmpeg are installed from trusted sources (PyPI/GitHub official releases) to avoid malicious packages; (2) note that SKILL.md mentions FFmpeg but the registry metadata doesn't list it — make sure ffmpeg is present on PATH; (3) the skill runs local binaries and may process large audio files (CPU/GPU, memory, and disk use), so monitor resource usage and run on appropriate hardware; (4) there are no requests for secrets or external endpoints, but if you adapt the instructions to upload files to cloud services, review those endpoints carefully; (5) if you want the skill to auto-install demucs, perform that installation yourself and verify package integrity rather than trusting an unverified automated install step.
Capability Analysis
Type: OpenClaw Skill
Name: music-seperator-demucs
Version: 1.0.1
The skill bundle is a legitimate wrapper for the Facebook Research Demucs audio separation tool. It contains standard CLI instructions, installation metadata via pip, and troubleshooting advice for FFmpeg and memory optimization, with no evidence of malicious intent, data exfiltration, or suspicious execution patterns.
Capability Assessment
Purpose & Capability
The skill is explicitly about running the Demucs CLI and the SKILL.md consistently documents demucs usage and options. One minor inconsistency: the runtime notes require FFmpeg (ffmpeg -version must succeed) but the registry metadata lists only demucs under required binaries. FFmpeg is reasonable and expected for audio processing but should be declared as a required binary.
Instruction Scope
SKILL.md only instructs the agent to run the Demucs CLI with documented flags, use absolute paths for automation, and troubleshoot typical local issues. It does not ask for unrelated files, system credentials, or to transmit data to external endpoints.
Install Mechanism
This is instruction-only (no install spec in registry), but SKILL.md metadata suggests installing Demucs via pip (demucs package). Installing via pip from PyPI is expected for this tool; there is no remote arbitrary-download URL or archive extraction. Users should verify installation comes from the official demucs package/repo.
Credentials
No environment variables, credentials, or config paths are requested. The skill does reference virtualenv executable paths for convenience, which is normal and proportional to the task.
Persistence & Privilege
The skill is not marked always:true and does not request persistent system-wide configuration or elevated privileges. It is user-invocable and uses standard CLI execution; autonomous invocation being allowed is the platform default and not a problem here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install music-seperator-demucs - After installation, invoke the skill by name or use
/music-seperator-demucs - Provide required inputs per the skill's parameter spec and get structured output
