Map Niche into Pillars Clusters and Internal Links

Unlike free topical-map and keyword-cluster prompts that brainstorm a content hub from memory, this skill runs a bundled offline Python script (standard library only, no API keys) on your own keyword list. It writes clusters.csv (every keyword with its cluster) and links.csv (pillar → cluster, cluster → pillar and sibling links with suggested anchors). Your agent then turns them into one page per intent, an 11-facet coverage check, COVERED / PARTIAL / GAP status for your existing URLs and a publishing order sized to your capacity. Volumes appear only if they are in your data; no ranking promises or "authority scores".

Sample output (excerpt; input: 13 email-marketing keywords · pillar "email marketing" · threshold 0.5 · no volumes supplied): Wrote topical-map-clusters.csv (13 keywords -> 6 clusters) and topical-map-links.csv (24 links). Pillar: 'email marketing' Note: 3 single-keyword clusters - merge manually or lower --threshold.

Review step (the skill's method, not the script): the clustering is lexical, so merge single-keyword clusters that share an intent (the two newsletter-template clusters) and split clusters that mix intents (C01 mixes "tips/ideas" with "software").

You get 3 files every time: topical-map-clusters.csv, topical-map-links.csv and topical-map.md with 7 sections: pillar page, cluster pages (primary/supporting keywords, intent, page type, facet, status), facet coverage, internal-link matrix, publishing calendar, cannibalisation watch, verify checklist.

The problem Blogs grow one random post at a time. Pages compete with each other, topics are half covered, and internal links are an afterthought.

What it does

• Clusters your keyword list offline into one-intent pages (clusters.csv)
• Builds the pillar ↔ cluster ↔ sibling internal-link plan with suggested anchors (links.csv)
• Checks coverage against 11 topic facets so nothing obvious is missing
• Maps your existing URLs as COVERED / PARTIAL / GAP to stop duplicate posts
• Gives you a publishing order sized to how many posts you can ship a week

Why this beats prompting it yourself The clustering and link matrix come from a script run on your real keyword list, so the plan is repeatable and checkable instead of a one-off brainstorm. Volumes appear only if they're in your data.
