## Description

Find recurring concept combinations across the wiki that lack an explicit synthesis page, then create cross-cutting synthesis pages. Use for knowledge synthesis after the vault has accumulated enough material.

# 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.

1. **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`).
2. Read `index.md` to get the full page inventory.
3. Read `hot.md` if it exists, it surfaces recent activity and active threads that may already point to synthesis opportunities.
4. Read `_meta/taxonomy.md` to understand the tag vocabulary.

When writing internal links in synthesis pages, apply the link format from `llm-wiki/SKILL.md` (Link Format section) using the `OBSIDIAN_LINK_FORMAT` value.

## Step 1: Build the Co-occurrence Map

Scan every non-special page in the vault (skip `index.md`, `log.md`, `hot.md`, `_insights.md`, `_meta/*`, `_archives/*`, `_raw/*`).

For each page, collect:
- All `[[wikilinks]]` it contains (outgoing links)
- Its `tags` frontmatter
- Its `category` frontmatter

Build a co-occurrence matrix: for every pair of concept/entity pages (A, B), count how many other pages link to **both** A and B. This is their co-occurrence score.

You don't need to be exhaustive, aim for the top 20-30 pairs by co-occurrence score. Use Grep to find backlinks efficiently:
