Description
Generate short sound effects via ElevenLabs SFX (text-to-sound). Use when you need SFX clips like applause, canned laughter, whooshes, ambience, or short stingers, and optionally convert to WhatsApp-friendly .ogg/opus.
Usage Guidance
This skill appears to do what it says: it posts your text prompt to ElevenLabs' sound-generation API and saves the returned audio file. Before installing, consider: (1) supply an ELEVENLABS_API_KEY (or XI_API_KEY) in your environment — the registry metadata omitted this requirement; (2) any prompt you send will be transmitted to ElevenLabs, so do not include sensitive information in prompts or files; (3) the skill writes the output file path you provide — choose a safe location and ensure you trust the skill owner since the homepage is not provided; (4) ffmpeg is recommended for optional conversion but is not invoked by the script automatically; install it separately if you need .ogg/opus conversion. If you want stronger assurances, ask the publisher for a homepage/source repo or sign the script before use.
Capability Analysis
Type: OpenClaw Skill Name: sound-fx Version: 0.1.1 The skill bundle is benign. It generates sound effects using the ElevenLabs API as described. The `scripts/generate_sfx.sh` script securely retrieves the API key from environment variables, constructs a standard JSON payload, and makes a legitimate POST request to `https://api.elevenlabs.io/v1/sound-generation`. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, prompt injection attempts in `SKILL.md`, or obfuscation. All actions are clearly aligned with the stated purpose.
Capability Assessment
Purpose & Capability
Name/description (ElevenLabs SFX text-to-sound) align with the included script and examples. The script calls ElevenLabs sound-generation endpoint, accepts a text prompt, duration, model and format options, and writes an audio file — all expected for a sound-effect generator.
Instruction Scope
SKILL.md stays on-topic: it explains setting an API key, how to run the script, and optional ffmpeg conversion. The runtime script only reads the prompt/duration/env API key and posts to the ElevenLabs API; it does not attempt to read unrelated files or system state.
Install Mechanism
No install spec is provided (instruction-only + a small helper script). Nothing is downloaded or written during installation, so install risk is low.
Credentials
The script requires an ElevenLabs API key (ELEVENLABS_API_KEY or XI_API_KEY) but the registry metadata listed no required env vars. This is likely an oversight in the metadata rather than malicious behavior, but users should be aware that an API key must be provided at runtime and will be used in outbound requests to api.elevenlabs.io.
Persistence & Privilege
The skill is not always-enabled, does not request special persistent privileges, and does not modify other skills or global agent configuration. It simply runs a short script that posts to ElevenLabs and saves an audio file.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install sound-fx
  3. After installation, invoke the skill by name or use /sound-fx
  4. Provide required inputs per the skill's parameter spec and get structured output
