Wiki Synthesize

Scans your Obsidian vault for concepts that show up together frequently across pages but have no dedicated synthesis page connecting them, then creates new pages in synthesis/ that draw explicit cross-cutting conclusions. It builds a co-occurrence matrix by grepping for wikilinks, scores candidates based on frequency and cross-domain overlap, and generates pages titled "Concept A × Concept B" with the insight that only becomes visible when you look at both together. Run it when you say "synthesize my wiki" or after a large ingest when the vault has grown enough that patterns are emerging but connections aren't explicit yet. The real discipline here is that synthesis pages must add something neither source says alone, otherwise you're just making noise.

Wiki Synthesize — First-Class Synthesis Discovery

You are scanning the wiki for concepts that co-occur across many pages but have no dedicated synthesis page connecting them. Your job is to surface these gaps and fill the most valuable ones with cross-cutting synthesis pages.

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.

Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (inline @name override → walk up CWD for .env → global config → prompt setup). This gives OBSIDIAN_VAULT_PATH and OBSIDIAN_LINK_FORMAT (default: wikilink).
Read index.md to get the full page inventory.
Read hot.md if it exists — it surfaces recent activity and active threads that may already point to synthesis opportunities.
Read _meta/taxonomy.md to understand the tag vocabulary.
