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-keyword-clustering 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 11d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenSEO Keyword Clustering

Group keywords into page-level clusters and assign each to an existing URL, a new page proposal, or a do-not-target bucket. Output lands in marketing/seo/clusters/*.md (per-cluster briefs) and feeds seo-content / seo-machine with measured page targets.

On Activation

  1. Catalog + binding: mktg catalog info openseo --json --fields configured and .seo/openseo.json for projectId. No binding → openseo-project-setup first. No OpenSEO at all → do lexical clustering with Exa context but label every cluster "SERP-unvalidated."
  2. Keyword source: prefer (a) brand/keyword-plan.md populated sections, (b) list_saved_keywords with a tag, (c) GSC live data, (d) seed discovery via research_keywords. Under 10 usable terms → simple map, no clustering ceremony.

OpenSEO MCP Tools

  • get_search_console_performance with dimensions: ["query","page"]: the cannibalization truth source — one query splitting impressions across multiple URLs means existing cannibalization, not theoretical risk.
  • get_ranked_keywords: domain/page-driven clustering from exact ranking rows + URLs.
  • get_serp_results: SERP-overlap validation for borderline terms (small batches, ≤10).
  • list_saved_keywords / research_keywords: source sets.
  • save_keywords: apply cluster tags ONLY after confirmation.

Workflow

  1. Assemble the candidate set from the source hierarchy above; dedupe and drop off-strategy terms.
  2. Cluster by intent and page type: same SERP intent + similar ranking pages belong together; different intent/buyer stage/SERP format splits. Lexical similarity is NOT evidence of same-page fit.
  3. Borderline terms: small get_serp_results overlap check.
  4. Assign each cluster: existing URL (if supplied and fitting), new-page proposal, or do-not-target/later.
  5. Cannibalization check: GSC query+page data first; otherwise flag where two proposed pages share one intent.
  6. Write per-cluster briefs to marketing/seo/clusters/<cluster-slug>.md: page type, searcher problem, required sections, internal-link targets, priority.
  7. Optionally tag clusters with save_keywords after confirmation.
  8. Hand off: seo-content for single pages, seo-machine for programmatic batches — both now have measured targets instead of vibes.

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.
