page-langs

Detect all languages used on a webpage, declared and in the body text, with web page langs (browser pass plus Google CLD3 WASM for content detection).

Requirements

Node 22+ and playwright-cli >= 0.1.20 on PATH (playwright-cli --version). Locate the web CLI once:

# <skill-dir> is the directory containing this SKILL.md
WEB=$(command -v web || echo "node <skill-dir>/../../cli/dist/web.mjs")

then run $WEB …; it prints exactly one JSON document on stdout, so $WEB … > file.json is safe. Fallback when published: npx -y @adobe/web-cli. Use an absolute <skill-dir>; don't cd into it.
