seo-repo-ecosystem-map-v1-9-0-nucleus-plus-three-satellites
AgriciDaniel/claude-seo v1.9.0 (released 15-Apr-2026) is the nucleus absorbing dancolta/seo-drift-monitor (fully merged as seo-drift) and matej-marjanovic/claude-seo (redundant fork—skip). Three repos still hold unmerged unique value: Drfiya/semantic-cluster-engine (execution layer: cluster-context block, backward link injection, scorecard), tools-enerix/claude-sxo-skill (wireframe/prototype/persona—3 of 4 SXO stages unmerged), and Chriss54/claude-blog-multilingual (entire orchestrator + translate/localize/audit unmerged). Install v1.9.0 as foundation, layer these three on top.
