# Build brief — a focused alternative to Surfer SEO

## Context

**Surfer SEO** — SEO content optimization and AI writing based on SERP analysis. It currently costs $99/mo.

A SERP-scrape-to-content-brief tool is buildable, but reliable SERP data, NLP scoring, editor workflow, AI articles, audits, and integrations create ongoing work.

This brief describes a focused, single-operator replacement for the part of Surfer SEO that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

## What you are building

Fetch top SERP pages via API, extract headings/entities/terms, score a draft, and produce brief/editor suggestions.

- Automate a bounded research or reporting workflow using permitted data sources.
- A responsive interface with real empty, loading, success, and error states.

## Requirements

### Functional

- Web scraper/parser.
- Content editor.
- Scoring logic.
- Hosted backend.

### Data and integrations

- Search/SERP API.
- LLM API.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

### Non-functional

- Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
- Security: server-side secrets, validated input, and no credentials in the client bundle.
- Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
- Portability: the operator can export their data and leave without losing it.

## Implementation brief

Build me a content-brief and draft-scoring tool to replace Surfer SEO, personal scale. Requirements:

- A Node CLI with two commands: brief "<keyword>" and score <draft.md> "<keyword>".
- brief: fetch the top 10 results from Serper.dev (key in .env), download each page,
  extract title, headings, and body text with cheerio + @mozilla/readability.
- Compute across the winners: median word count, recurring H2/H3 topics, and the 30
  most frequent meaningful terms via simple tf-idf. No NLP service.
- Send that to an LLM (key in .env) to write briefs/<keyword>-YYYY-MM-DD.md: suggested
  outline, target word count, terms to cover, questions to answer.
- score: compare my draft against the brief's term list and outline, print a coverage
  percentage and a table of missing terms in the terminal.
- Cache every SERP response and fetched page in SQLite (better-sqlite3) so re-runs
  cost zero API credits.
- No accounts, no telemetry, everything local except the Serper and LLM calls.
- Out of scope: a writing editor with live scoring, site audits, and rank tracking.
  This outputs Markdown briefs, and page scraping will break on some sites · Serper
  is the one paid dependency, say both in the README.
- README: where to get the Serper key and the rough API cost per brief.

## Delivery standard

- Inspect the repository first, then write a short implementation plan before writing code.
- Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
- Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
- Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
- Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
- Add structured logs around every external call and return actionable errors without leaking sensitive details.
- Write unit tests for the core logic and one automated test of the main user journey.
- Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

## Acceptance criteria

- [ ] A clean install starts the app using only the README and .env.example.
- [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
- [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
- [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
- [ ] Tests, type checking, linting, and a production build all pass with no ignored failures.
- [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

## Non-goals

Do not build these, and do not claim to have replaced them:

- SERP data reliability.
- Scoring model.
- Editor UX.
- AI article workflows.
- The useful dataset is owned, accumulated, or expensive to reproduce.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.

## What you still own after launch

- Secure credentials, rotate secrets, and handle provider rate limits.
- Run migrations, backups, restores, and dependency updates.
- Test the critical journey after every model, API, or hosting change.
- Monitor failures and fix the edge cases a first prompt will miss.
- Maintain every third-party integration as APIs and OAuth rules change.

## Risk

**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.
