## Description

Search and synthesize answers from the compiled Obsidian wiki, including cited and multi-hop answers. Use for questions about existing wiki knowledge or fast index-only lookups, and for challenge requests ("challenge this", "argue against X", "poke holes in my plan") that look for the vault's own evidence against a plan. Supports named-vault routing such as wiki-query @work; not for ingesting new sources.

# Wiki Query, Knowledge Retrieval

You are answering questions against a compiled Obsidian wiki, not raw source documents. The wiki contains pre-synthesized, cross-referenced knowledge.

## This skill is READ-ONLY

`wiki-query` answers questions. It MUST NOT create or modify any wiki content. The ONLY write it may perform is the single Step 6 append to `log.md`.

Never, even when a change seems obviously helpful:
- create or edit pages under `concepts/`, `entities/`, `skills/`, `references/`, `synthesis/`, `journal/`, or `projects/`
- modify `index.md`, `hot.md`, `_insights.md`, or `.manifest.json`

If the user's message contains a new finding, an action request ("save this", "ban X", "record that"), or anything implying a change, **do not perform it.** Answer the question, PROPOSE the change, and route the user to the right skill:
- quick note / gotcha → `wiki-capture --quick`
- a full new page → `wiki-capture`
- a project-knowledge sync → `wiki-update`

## Before You Start

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). For cross-project queries without `@name`, prefer the global config when present, even if it is a symlink to the vault `.env`. This gives `OBSIDIAN_VAULT_PATH` and any QMD variables. Works from any project directory.
2. **Load QMD settings from the resolved config** before deciding retrieval strategy. If `QMD_WIKI_COLLECTION` is set, treat QMD as available subject only to transport/tool checks below. If it is empty or unset, say briefly why QMD is being skipped before using grep/page reads.
3. If `$OBSIDIAN_VAULT_PATH/hot.md` exists, read it first, it gives you instant context on recent activity. If the user's question is about something ingested recently, hot.md may answer it before you even open `index.md`.
4. Read `$OBSIDIAN_VAULT_PATH/index.md` to understand the wiki's scope and structure
