openclaw-wasm-sandbox~/.openclaw/skills/opencv/files/opencv-component.wasmbash
openclaw wasm-sandbox download \
"https://raw.githubusercontent.com/guyoung/wasm-sandbox-openclaw-skills/main/opencv/files/opencv-component.wasm" \
"~/.openclaw/skills/opencv/files/opencv-component.wasm"Use wasm-sandbox-run tool with the WASM file:
wasm-sandbox-run({
wasmFile: "~/.openclaw/skills/opencv/files/opencv-component.wasm",
args: ["<operation>", ...args]
})
For file access, use workDir or mapDir to expose directories to the sandbox.
