    Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.
    Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.

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

openseo 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 8d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenSEO — SEO Data Plane

You connect mktg's SEO playbooks to a running OpenSEO instance (hosted at openseo.so or self-hosted Docker). You do NOT invent metrics. You do NOT call DataForSEO directly. You route measured data (KD, volume, SERP, ranked keywords, backlinks, rank tracking, GSC) into mktg artifacts like brand/keyword-plan.md.

OpenSEO is a data plane, not a playbook. The SEO methodology lives in keyword-research, seo-content, seo-audit, off-page-seo, ai-seo, and seo-machine — this skill is how those playbooks stop guessing.

North Star

  1. Measured data beats estimated data. When OpenSEO is configured, metrics come from OpenSEO's MCP tools. When it is not, you say so explicitly and fall back to Exa-backed qualitative research — metrics marked unknown.
  2. mktg never calls DataForSEO directly. OpenSEO owns the vendor relationship; mktg talks to OpenSEO only.
  3. Expensive calls (bulk research, save_keywords) follow dry-run/confirm discipline — DataForSEO credit is real money.
  4. OpenSEO project state syncs into .seo/ and brand/keyword-plan.md; it never becomes a competing second source of truth.

On Activation

Run these steps before anything else. Each has a fallback that keeps the skill useful when OpenSEO is absent.

Step 1 — Verify the catalog is registered and configured

mktg catalog info openseo --json --fields configured,missing_envs,auth.credential_envs,mcp
  • Exit code 1 → the openseo catalog is not registered (upgrade marketing-cli). Stop.
  • configured: false → env vars are missing. Build the fix string from missing_envs. Canonical envs: OPENSEO_API_KEY (required for non-interactive automation) and OPENSEO_API_BASE (REST base; self-host override). The MCP URL is mcp.default_url (https://app.openseo.so/mcp) unless OPENSEO_MCP_URL overrides it for self-host.
  • configured: true → proceed. If only the MCP client is connected (OAuth login in the user's agent client) but no API key exists, treat readiness as mcp_client_only: MCP tools work interactively, headless automation does not.

What this file has done since we first saw it

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.
