Description
Computer vision and image processing using OpenCV WebAssembly. Uses opencv-component.wasm running in openclaw-wasm-sandbox plugin. Supports image processing,...
Usage Guidance
This skill appears to do what it says (run OpenCV in a WASM sandbox), but before installing or using it you should: 1) verify the WASM binary's provenance — prefer official releases or a checksum/signature; 2) avoid mapping wide host paths (don't expose your entire home or system directories); map only the specific image directories needed; 3) confirm the openclaw-wasm-sandbox enforces isolation (no network access and restricted file access) or explicitly limit allowed-outbound-hosts before running model/dnn operations; 4) if possible, inspect the WASM source or run it in a disposable environment first; and 5) prefer a skill that provides an install spec with signed artifacts or an official homepage/repository. These precautions reduce the risk of executing untrusted code or accidental data exposure.
Capability Analysis
Type: OpenClaw Skill
Name: opencv
Version: 1.0.0
The skill provides a legitimate interface for computer vision tasks using OpenCV compiled to WebAssembly. It utilizes the 'openclaw-wasm-sandbox' to execute operations like image processing, object detection, and machine learning in a restricted environment. No evidence of malicious intent, data exfiltration, or prompt injection was found; the instructions and documentation (SKILL.md and references/operations.md) are strictly aligned with the stated purpose of providing image manipulation tools.
Capability Assessment
Purpose & Capability
Name and description match the instructions: the skill expects an OpenCV WebAssembly component and the openclaw-wasm-sandbox plugin. Declared prerequisites (plugin + wasm file) are consistent with the stated functionality.
Instruction Scope
Runtime instructions are narrowly scoped to invoking the wasm component via wasm-sandbox-run and mapping workDir/mapDir for file I/O. The skill does instruct mapping arbitrary host directories into the sandbox (expected for image files) — this is normal for the task but increases the risk of exposing unrelated sensitive files if mappings are too broad.
Install Mechanism
No formal install spec is present; SKILL.md instructs downloading a WASM file from a raw.githubusercontent.com URL. While GitHub raw is a common host, the skill provides no checksum/signature or provenance guidance. Downloading and executing an externally-hosted WASM blob is moderate-to-high risk if unverified.
Credentials
The skill requests no environment variables, credentials, or config paths. This is proportionate to an image-processing WASM component. Note: the ability to map host directories into the sandbox effectively grants the component access to any mapped files.
Persistence & Privilege
No always:true flag, no install-time modifications described, and the skill is instruction-only. It does not request persistent elevated privileges via the metadata.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install opencv - After installation, invoke the skill by name or use
/opencv - Provide required inputs per the skill's parameter spec and get structured output
