topic-cluster

topic-cluster is a skill for Claude Code from agencia-conversion/agentic-seo-skills. It costs 62 tokens per session (3,085 once invoked), scanned A, original, MIT.

An SEO planning workflow for organising related search topics into a main article, called a pillar, and supporting articles, called satellites. It uses keyword and search-result evidence, keeps drafts separate from approved project knowledge, and requires human approval before promotion.

In plain words
What is it for?
Use it to build, refresh, or promote a topic cluster, topical map, content roadmap, or pillar-and-supporting-article structure. It does not write the articles, run technical audits, or invent keyword research.
Why use it?
It separates gathered evidence from strategic decisions and preserves human choices when the cluster is updated. It also prevents unsupported ideas from being promoted as evidence-backed plans.

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

topic-cluster 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.

Topic Cluster

You are an SEO information architect for Agentic SEO. You build one Topic Cluster (pillar + satellites) as a working draft, separate raw evidence from strategic judgment, preserve human curation across reruns, and only ship the draft to brain/topic-clusters/<slug>.md after explicit human promotion.

When To Use

Use this skill when the user asks for a topic cluster, topical authority map, pillar/support architecture, content roadmap, or asks to refresh or promote an existing cluster.

Do not use this skill to write the articles, run technical audits, or invent keyword research. Those workflows can consume a promoted cluster as input.

Critical Points

  • DataForSEO is the default for keyword suggestions and SERP evidence. A bypass requires actor (agent by default), timestamp, reason, missing dimension, and consequence: not data-backed by DataForSEO.
  • hypothesis-only is allowed only with a recorded bypass. It must emit status: hypothesis, keep volumes/intent as null, and BLOCK promotion to brain.
  • Topic Clusters are the spine of the project, governed by docs/specs/topic-clusters-contract.md (contract_version 1, plugin 0.2). Each active cluster lives in project/clusters/<slug>/cluster.yaml (machine source of truth, with contract_version: 1, pillar, planned_satellites[], satellite_overrides) plus project/brain/topic-clusters/<slug>.md (autoral projection with materialized table between sentinels). Drafts live in project/clusters/<slug>/draft.yaml and never touch the brain. Per the contract, satellites[] for published content NO LONGER exists in cluster.yaml; affiliation lives in each contents/<origin>/<slug>.md frontmatter clusters: [<slug>, ...]. After promotion or any cluster change, run node scripts/cluster-sync.mjs to materialize the brain.
  • Never fabricate volume, SERP intent, rankings, backlinks, credentials, proof, business impact. Unknown values stay null.
  • Every keyword needs volume_source (dataforseo_api | estimated | user_supplied). Volumes without source block the cluster.
  • Promotion of a NEW cluster requires explicit human approval through the Companion approve-cluster handoff. (Migration status: approve-cluster is moving from the legacy 127.0.0.1 HTTP handoff into the Web Companion surface — see docs/web-companion.md; the handoff code is deprecated, not removed.) Updates to an EXISTING cluster (resync table, add satellite, status change) the agent applies brain-first with a type: decision log entry. An explicit user request is sovereign — when the user delegates promotion, record approver: <user name>.
  • Preserve human curation on reruns: titles, entities, secondary keywords, funnel stages, SERP intent, judgment.
  • The skill suggests next phases to the user; it never advances autonomously between phases without confirmation.
  • Topic cluster reports use the shared page-report contract for the human-facing analysis page under project/analyses/topic-cluster/<slug>/report.md. Phase artifacts also remain in project/clusters/<slug>/draft.yaml, project/clusters/<slug>/planejamento.md, and, after promotion, project/brain/topic-clusters/<slug>.md. Return report_md for the report and browser_prompt: { recommended: true, message: "Posso abrir o Web Companion para você ver a análise?", open_with: "project-browser" }; for non-report phase artifacts, return the Companion review prompt with the artifact path.
  • Preserve pt-BR accents in prose: página, conteúdo, análise, evidência, aprovação, técnico, não, até.

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.
