Wiki Dedup

Finds pages in your Obsidian vault that cover the same concept under different names (like "RSC" and "React Server Components") and merges them into a single canonical page. It scores pairs by title similarity, aliases, and tags, then reads the content to decide whether they're truly duplicates or just related. Runs in audit mode by default so you can review before it does anything destructive, or you can auto-merge high-confidence matches. Useful when your wiki has accumulated accidental duplicates or you've been inconsistent with abbreviations. Heavier than wiki-lint since it actually rewrites pages and creates redirect stubs, so the confirmation step matters.

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.

Before You Start

Writing profile: Before drafting or rewriting natural-language Markdown, read and apply the Writing Profile Resolution section in llm-wiki/SKILL.md. Framework schema, provenance, safety, and operation-specific requirements take precedence. WRITING.md preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.
