Frase

Build me a content-brief generator to replace Frase. Requirements: - A Node CLI: `brief "<keyword>"` writes ./briefs/<keyword-slug>.md. - Fetch the top 10 results for the keyword from Serper.dev (key in .env). - Scrape each result with Playwright plus Readability: title, H2/H3 outline, word count, and any questions found on the page. - Send the aggregate to an LLM (key in .env) to produce the brief: suggested title and angle, a target outline, questions to answer, terms competitors cover, and a word-count range. - `score <draft.md> "<keyword>"` re-checks my draft against the brief: which terms and questions are covered or missing, with a plain coverage percentage. - Cache scraped pages in ./cache/ keyed by URL so re-runs cost nothing. - Flat files only, no database; no accounts, no telemetry, the only network calls are the SERP API, page fetches, and the LLM. - Out of scope: an editor UI, rank tracking, team workflows. Briefs are Markdown, I write in my own editor. - README: which keys to get and the rough per-brief cost of the SERP API.
