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.
