keyword-cluster

Build a pillar+spokes content cluster plan from seed keywords — SERP-overlap clustering via keyword_cluster.py, intent grouping, a priority-scored build order, an internal-link map with anchor suggestions, and a four-gate quality scorecard (cannibalisation, orphan, coverage, anchor diversity), delivered as a numbered file set ending in PLAN.md. Triggers on "/digital-marketing-pro:keyword-cluster", "cluster these keywords", "design our topical hub", "are these pages cannibalising each other", "plan the pillar pages". Reads the brand profile and compliance rules to filter banned terms; consumes seeds from /digital-marketing-pro:keyword-research and hands PLAN.md to /digital-marketing-pro:content-brief.
