seo-project-setup is a skill for Claude Code, Codex from every-app/open-seo. It costs 36 tokens per session (2,138 once invoked), scanned A, original, MIT.

A setup workflow that records the shared context for one SEO project, including its website, goals, positioning, competitors, important pages, and writing preferences. SEO means improving a website's visibility in search engines.

In plain words
What is it for?
Collecting project details, adding competitors and key pages, saving preferences, checking existing context, and taking in Search Console information.
Why use it?
It prevents repeated interviews and gives later SEO workflows the business context needed to produce relevant work.

This is every-app/open-seo's own configuration. It tells Claude Code and Codex how to work on open-seo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-seo configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seo-project-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenSEO SEO Project Setup

Goal

Interview the user once about one website or SEO project, and store the answers in that project's shared context in OpenSEO with update_project_context. That context is read by every other skill and by the user on the project's Context page (in the sidebar under AI) — so it survives new sessions, new machines, and new agents. This is a context setup workflow, not a full audit.

Tone

Be friendly, practical, and structured. Ask questions in small batches. Explain why each item matters only when useful. Do not overwhelm a beginner with jargon.

Where the answers go

Two project-context MCP tools do all the writing. Both are free — they spend no credits.

  • get_project_context(projectId): everything already known about the project, plus a missingSections list.
  • update_project_context(projectId, updates): a list of patch ops. The ones this skill uses:
    • { section: "business_overview" | "current_goal" | "positioning" | "writing_preferences", content }
    • { addCompetitors: [{ domain, name?, notes? }] }
    • { addKeyPages: [{ url, role: "hub" | "spoke" | "money" | "other", topic?, notes? }] }
    • { customSection: "<slug>", title?, content } for anything that does not fit a typed section
    • { appendResearchLog: { summary } } when this session spends credits

Write in batches as the interview progresses — do not hold every answer until the end. Sections are prose (~4,000 characters each), so a few tight paragraphs, not a transcript.

Checklist

1. Verify OpenSEO MCP and resolve the project

Writes need a projectId, so do this first:

  1. Use whoami if available.
  2. Use list_projects to confirm the user can access projects.
  3. Match the project to the website/domain they want to rank for.
  4. If the project list is ambiguous, ask the user which project should be used.
  5. If no project matches, offer to create one with create_project.
  6. If the MCP is unavailable, tell the user to connect OpenSEO MCP; without it, nothing can be saved.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
