seodraft

An SEO/AEO content engine that lives in your repo, powered by the agent you already pay for.

It installs an agent skill plus a set of dependency-free Node scripts into the AI coding harness you already run, and turns it into a content operation: keyword research, a content calendar, article generation, and a deterministic pre-publish gate.

No SaaS. No model API keys. Your articles are Markdown files in your repo and your state is JSON files you can read in a diff.

---

How it works

The division of labor is the whole design:

Your agent proposes	keywords, schedules, research, drafts, fix suggestions
Deterministic code decides	15 gate rules, 18 audit rules — no LLM, no network, milliseconds
You approve	nothing is published or edited without you

A reviewer gets tired; a gate does not. Every question with a factual answer (is the meta description within budget, does this internal link resolve, is this term already covered by another post) is answered by a script on every article, forever. Everything that needs taste stays with you and your agent.

Requirements

• Node.js ≥ 18
• A Markdown/MDX content repo — Astro, Next.js, Hugo and Jekyll are detected automatically, and Markdoc/Keystatic (.mdoc) works too
• One of: Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Pi

Install

From your content repo:

npx seodraft@latest install

install detects which harness folders exist (.claude, .agents, .cursor, .gemini, .opencode, .pi), asks you to confirm, and copies the skill in. Pass --providers=claude,cursor to skip the prompt, or --scope=global to install into ~ instead of the project. update re-copies over an existing install — run it after bumping the package.

Installing globally works too, and gives you the CLI on PATH for CI use:

npm install -g seodraft

To run from source instead:

git clone https://github.com/ch0rch/seodraft.git
cd seodraft && pnpm install
node /path/to/seodraft/bin/seodraft.mjs install   # from your content repo

Then open your agent in your content repo and run /seodraft init.

Pi

Pi loads seodraft as a native package, in place — nothing is copied into your repo and pi update keeps it current:

pi install npm:seodraft

Install it without a version: a pinned spec (npm:seodraft@0.2.0) is deliberately skipped by pi update --extensions. The package ships the skill plus a /seodraft <command> prompt template; /skill:seodraft works too.

Pick one route per machine — the package or seodraft install --providers=pi. Both at once makes pi report a seodraft name collision and load only the first one it finds. And if you already installed for Codex, pi picks the skill up for free: it reads .agents/skills/ as well.

Commands

Inside your agent:

command	what it does
/seodraft init	detects your framework, interviews you about the business, writes .seodraft/config.json + profile.md
/seodraft keywords	builds the keyword bank — real metrics via DataForSEO, or clearly-marked estimates without it
/seodraft plan	schedules stored keywords into a content calendar
/seodraft write	research → outline → draft → gate, then updates state. Max 2 redrafts, then it stops
/seodraft audit	deterministic audit of existing content, with fixes applied only after you approve
/seodraft status	queue, keyword coverage, AEO coverage, last audit counts

The same scripts run headless for CI, no harness required:

seodraft gate content/blog/my-post.mdx --term "target keyword"   # exit 1 on failure
seodraft audit --file content/blog/my-post.mdx                   # always exit 0
seodraft state validate

The gate

gate.mjs blocks an article on any error-severity failure. It is the reason a bad draft never becomes a file you have to clean up later.

rule	severity
frontmatter-parse, frontmatter-complete	error
title-length, description-length	error
h1-policy, heading-structure	error
internal-links-min, broken-internal-link	error
cannibalization	error
placeholder-text	error
tldr-length, faqs-min	error
cannibalization-fuzzy, thin-content, faq-answer-length	advisory

cannibalization is a hard stop, never a redraft: if a term is already covered by one of your posts, a second post splits your own ranking. The agent is forbidden from rephrasing around it.

AEO

Three canonical fields exist because answer engines quote structure, not prose:

• tldr — a self-contained answer to the target term. This is the block an answer engine lifts.
• faqs — quotable question/answer pairs.
• updatedDate — the freshness signal. It feeds dateModified in your structured data; without it, a post you refreshed can never say so.

The same AEO rules are errors in the gate and advisories in the audit. That split is deliberate. New content has no excuse for missing fields your own schema declares. But erroring every post in a legacy archive that predates the standard produces noise, not signal, and buries the findings that matter. A missing TL;DR on a three-year-old post is an opportunity; a missing meta description was always a defect.

Configuration

.seodraft/config.json (committed) maps nine canonical fields onto whatever your repo actually calls them. Values may be dot-paths into nested frontmatter, and null means the field is unused here — which also disables its rules.

{
  "schemaVersion": 1,
  "siteUrl": "https://example.com",
  "language": "en",
  "locationCode": 2840,
  "framework": "astro",
  "contentDir": "src/content/blog",
  "extension": ".mdx",
  "frontmatter": {
    "title": "seo.seoTitle",
    "description": "seo.seoDescription",
    "date": "publishedDate",
    "updatedDate": "updatedDate",
    "image": "coverImage",
    "tags": "category",
    "draft": "draft",
    "tldr": "seo.tldr",
    "faqs": "faqs"
  },
  "bodyH1": false,
  "internalLinksMin": 2,
  "thinContentWords": 500,
  "titleMax": 60,
  "descriptionMax": 160,
  "tldrMin": 100,
  "tldrMax": 400,
  "faqsMin": 3,
  "faqAnswerMax": 500
}

State files, all in .seodraft/:

file	committed	holds
config.json	yes	the above
profile.md	yes	business, audiences, competitors, voice, instructions
keywords.json	yes	the keyword bank
calendar.json	yes	scheduled entries
config.local.json	no	DataForSEO credentials

Keyword metrics are optional

DataForSEO gives you real search volume and difficulty. Without credentials, dataforseo.mjs exits 0 with {"degraded": true, "reason": "missing-credentials"}, and the agent estimates the metrics instead, marking those entries source: "estimate". Real measurements always overwrite an estimate; an estimate never overwrites a measurement.

Credentials go in DATAFORSEO_LOGIN / DATAFORSEO_PASSWORD or in the gitignored .seodraft/config.local.json.

Contributing

Issues and pull requests are welcome. Start with CONTRIBUTING.md — it is short, and it covers the one constraint that is easy to break by accident: everything under skill/scripts/ must stay dependency-free, because those scripts run inside someone else's harness with no node_modules anywhere near them. CI enforces it mechanically.

pnpm install
pnpm test                # 81 tests, 10 suites
pnpm check:deps          # the dependency guard
pnpm smoke               # packs the tarball, installs it, runs it

There is no build step: skill/ is the product and the installer copies it. prompts/ is Pi-only: it is loaded straight out of the package and is never part of the copied skill.

fixtures/astro-blog/ is a content repo seeded with a known set of defects that the gate and audit tests assert against exactly — it is a test fixture, not sample data.
