Page Langs

What it does

When your agent uses it

• EDS page migrations
• Hreflang validation
• Multilingual content verification
• : detect languages

Example prompts

• “/page-langs”

Requirements

• Node.js
• Compatibility (from SKILL.md): Requires playwright-cli on PATH and Node 22+. One-time setup: run `npm install --prefix <skill-dir>` to install cld3-asm (WASM, model bundled, no native build). Run `playwright-cli --help` for the command reference.

Workflow steps

4 steps, taken from the step headings in SKILL.md.

1. 1Locate the scripts
2. 2Open the page
3. 3Collect signals and detect languages
4. 4Verify output

What it can do on your machine

Read from SKILL.md and the folder at commit cbc9952. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 2 files in scripts/ (JavaScript), which the agent can run.

  Shell commands in SKILL.md call:

  • npm
  • node

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires playwright-cli on PATH and Node 22+. One-time setup: run `npm install --prefix <skill-dir>` to install cld3-asm (WASM, model bundled, no native build). Run `playwright-cli --help` for the command reference.

  From compatibility in the SKILL.md frontmatter.

Context cost

Page Langs loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 210 tokens; SKILL.md has 318 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~210

When it runs · the whole SKILL.md, loaded when a task matches

~1.1k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Detect all languages used on a webpage — both declared (html@lang, hreflang alternate links, nested lang= attributes, meta content-language) and actually present in the body text (Google CLD3 via cld3-asm WASM). Reconciles the two signal sets and flags mismatches such as undeclared languages in the body or declared languages absent from the content. Outputs langs.json with detected languages (probability + proportion), all declared language signals, and a reconciliation report. Use for i18n audits, EDS page migrations, hreflang validation, and multilingual content verification. Triggers on: detect languages, page languages, what language, language detection, i18n audit, hreflang, hreflang validation, lang attribute, multilingual page, page-langs, language audit, which language, content language, undeclared language.

compatibility

Requires playwright-cli on PATH and Node 22+. One-time setup: run `npm install --prefix <skill-dir>` to install cld3-asm (WASM, model bundled, no native build). Run `playwright-cli --help` for the command reference.
