Blog Cluster

If you've ever manually written a pillar post and then realized you need twelve supporting articles that all link together correctly, this is the orchestration layer you were missing. It takes a seed keyword, pulls SERP data to find semantic clusters, generates a hub and spoke plan with an SVG map, then executes the whole thing by calling blog-write repeatedly with shared context so every post knows where it fits and auto-injects the right internal links. Adapted from Lutfiya Miller's semantic-cluster-engine (winner of the AI Marketing Hub Pro Challenge, March 2026), stripped of brand styling and ported to work with claude-blog's existing skills. Treats content ecosystems as architecture problems: plan the structure, then build it in one pass.
