What Wiki Dedup does

Wiki Dedup scans an Obsidian wiki for pages covering the same concept under different names and merges them. Use it when the user asks to deduplicate, find duplicate pages, or consolidate a vault.

Wiki Dedup is cataloged under Automation on DirSkills. Wiki Dedup comes from a repository tagged agent-skills, brain, knowledge-base, llm-tools and obsidian.

Documentation

README

Excerpt

Wiki Dedup — Identity Resolution and Page-Level Deduplication

You are finding and merging wiki pages that cover the same concept under different names. This is a write-heavy, potentially destructive skill — page merges cannot be automatically undone. Work carefully and confirm before acting in merge mode.

Follow the Retrieval Primitives table in llm-wiki/SKILL.md. The candidate-detection pass uses only frontmatter and titles (cheap). Only open full page bodies for confirmed candidate pairs.
