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. Before You Start Read ~/.obsidian-wiki/config to get OBSIDIAN_VAULT_PATH (works from any project). Fall back to .env if you're inside the obsidian-wiki repo. Read $OBSIDIAN_VAULT_PATH/index.md to understand the wiki's scope and structure Visibility Filter (optional) By default, all pages are returned regardless of visibility tags. This preserves existing behavior — nothing changes unless the user asks for it. If the user's query includes phrases like "public only" , "user-facing" , "no internal content" , "as a user would see it" , or "exclude internal" , activate filtered mode : Build a blocked tag set : {visibility/internal, visibility/pii} In the Index Pass (Step 2), skip any candidate whose frontmatter tags contain a blocked tag In Section/Full Read passes (Steps 3–4), do not read or cite any blocked page Synthesize the answer only from allowed pages — do not mention that excluded pages exist Pages with no visibility/ tag, or tagged visibility/public , are always included. In filtered mode, note the filter in the Step 6 log entry: mode=filtered . Retrieval Protocol Follow the Retrieval Primitives table in llm-wiki/SKILL.md . Reading is the dominant cost of this skill — use the cheapest primitive that answers the question and escalate only when it can't. Never jump straight to full-page reads. Step 1: Understand the Question Classify the query type: Factual lookup — "What is X?" → Find the relevant page(s) Relationship query — "How does X relate to Y?" → Find both pages and their cross-references Synthesis query — "What's the current thinking on X?" → Find all pages that touch X, synthesize Gap query — "What don't I know about X?" → Find what's missing, check open questions sections Also decide the mode : Index-only mode — triggered by "quick answer", "just scan", "don't read the pages", "fast lookup". Stops at Step 3. Answers from frontmatter + index.md only. Normal mode — the full tiered pipeline below. Step 2: Index Pass (cheap) Build a candidate set without opening any page bodies : You've already read index.md above — use it as the first filter. It lists every page with a one-line description and tags. Use Grep to scan page frontmatter only for title, tag, alias, and summary matches. A pattern like ^(title|tags|aliases|summary): scoped to vault .md files is far cheaper than content grep. Collect the top 5–10 candidate page paths ranked by: Exact title or alias match Tag match Summary field contains the query term index.md entry contains the query term If you're in index-only mode , stop here. Answer from summary: fields, titles, and index.md descriptions only. Label the answer clearly: "(index-only answer — page bodies not read; facts below are from page summaries and may miss nuance)" . Then skip to Step 5. Step 2b: QMD Semantic Pass (optional — requires QMD_WIKI_COLLECTION in .env ) GUARD: If $QMD_WIKI_COLLECTION is empty or unset, skip this entire step and proceed to Step 3. No QMD? Skip to Step 3 and use Grep directly on the vault. QMD is faster and concept-aware but the grep path is fully functional. See .env.example for setup. If QMD_WIKI_COLLECTION is set and the index pass didn't produce clear candidates — or the question requires semantic matching rather than exact terms — use QMD before reaching for Grep : mcp__qmd__query: collection: # e.g. "knowledge-base-wiki" intent: searches: - type: lex # keyword match — good for exact names, file paths, error messages query: - type: vec # semantic match — good for concepts, patterns, "what is X like" query: The returned snippets act as pre-read section summaries. If they answer the question fully, skip Step 3 and go straight to Step 4 (reading only the pages QMD ranked highest). If not, use the ranked file list to guide which files to grep or read in Step 3. Also search papers when the question may have source material in _raw/ : If QMD_PAPERS_COLLECTION is set and the user is asking about a topic likely covered by ingested papers (research, theory, background), run a parallel search against the papers collection. Cite raw sources separately from compiled wiki pages in your answer. Step 3: Section Pass (medium cost — only if Steps 2/2b are inconclusive) For each of the top candidates, pull the relevant section without reading the whole page : Use Grep -A 10 -B 2 "" to get just the lines around the match. This usually returns 15–30 lines per hit instead of 100–500. If the section grep gives a clear answer, go straight to Step 5. Step 4: Full Read (expensive — last resort) Only when Steps 2 and 3 don't answer the question: Read the top 3 candidates in full. Follow at most one hop of [[wikilinks]] from those pages if the answer requires cross-references. Check "Open Questions" sections for known gaps. If you're still short, then fall back to a broad content grep across the vault. Tell the user you escalated — this is the expensive path and they should know. Step 5: Synthesize an Answer Compose your answer from wiki content: Cite specific wiki pages using [[page-name]] notation Note which step the answer came from ("found in summary" vs "grepped section" vs "full page read") — helps the user understand confidence If the wiki has contradictions, present both sides If the wiki doesn't cover something, say so explicitly Suggest which sources might fill the gap Step 6: Log the Query Append to log.md : - [TIMESTAMP] QUERY query="the user's question" result_pages=N mode=normal|index_only|filtered escalated=true|false Answer Format Structure answers like this: Based on the wiki: [Your synthesized answer with [[wikilinks]] to source pages] Pages consulted: [[page-a]], [[page-b]], [[page-c]] Gaps: [What the wiki doesn't cover that might be relevant]
