## Description

Detect and merge wiki pages representing the same concept under different names. Use for page-identity deduplication and consolidation. Destructive merges require confirmation; not for link repair or general linting.

# 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.

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`.
2. Read `index.md` to get the full page inventory with one-line descriptions and tags.
3. Read `log.md` briefly, if a dedup run just happened, note what was already merged.

## Modes

| Mode | Flag | Behavior |
|---|---|---|
| **Audit** | *(default)* | Report candidates only, no writes |
| **Merge** | `--merge` | Show each confirmed pair, ask for confirmation before merging |
| **Auto-merge** | `--auto` | Merge all high-confidence pairs (`score ≥ 0.90`) non-interactively |

If the user doesn't specify, run in **Audit** mode and present findings before asking whether to proceed.

## Step 1: Build the Page Registry
