URL Ranked Keywords Extractor

独立 skill：只负责从指定 URL 拉取 Google 排名词。不依赖、不调用其他 SEO/GEO skill。

输入指定网页 URL，通过 DataForSEO API 提取该页面当前在 Google 中排名的关键词及相关指标。

Prerequisites

Prefer .env.local in the project (or git root). Shell export still works and wins.

# .env.local
DATAFORSEO_LOGIN=your_login
DATAFORSEO_PASSWORD=your_password

Do not commit it. Confirm the consuming repo gitignores .env / .env.*. Do not store credentials in the skill directory or paste the file into chat.

Lookup order: existing env → .env.local then .env (cwd up to git root, then the skill dir) → ~/.env.local / ~/.env / ~/.dataforseo.env. Only DATAFORSEO_* keys are read. No extra packages.
