Claude-obsidian wiki-query
Answer questions using the Obsidian wiki vault. Reads hot cache first, then index, then relevant pages. Synthesizes answers with citations. Files good answers back as wiki pages. Supports quick, standard, and deep modes. Triggers on: what do you know about, query:, what is, explain, summarize, find in wiki, search the wiki, based on the wiki, wiki query quick, wiki query deep.

skills/wiki-query/SKILL.mdwiki-query: Query the Wiki
The wiki has already done the synthesis work. Read strategically, answer precisely, and file good answers back so the knowledge compounds.
Query Modes
Three depths. Choose based on the question complexity.
| Mode | Trigger | Reads | Token cost | Best for |
|---|---|---|---|---|
| Quick | or simple factual Q | hot.md + index.md only | ~1,500 | "What is X?", date lookups, quick facts |
| Standard | default (no flag) | hot.md + index + 3-5 pages | ~3,000 | Most questions |
| Deep | or "thorough", "comprehensive" | Full wiki + optional web | ~8,000+ | "Compare A vs B across everything", synthesis, gap analysis |
Quick Mode
Use when the answer is likely in the hot cache or index summary.
- Read
. If it answers the question, respond immediately.wiki/hot.md - If not, read
. Scan descriptions for the answer.wiki/index.md - If found in index summary, respond and do not open any pages.
- If not found, say "Not in quick cache. Run as standard query?"
Do not open individual wiki pages in quick mode.
Standard Query Workflow
- Read
first. It may already have the answer or directly relevant context.wiki/hot.md - Read
to find the most relevant pages (scan for titles and descriptions).wiki/index.md - Read those pages. Follow wikilinks to depth-2 for key entities. No deeper.
- Synthesize the answer in chat. Cite sources with wikilinks:
.(Source: [[Page Name]]) - Offer to file the answer: "This analysis seems worth keeping. Should I save it as
?"wiki/questions/answer-name.md - If the question reveals a gap: say "I don't have enough on X. Want to find a source?"
Deep Mode
Use for synthesis questions, comparisons, or "tell me everything about X."
- Read
andwiki/hot.md
.wiki/index.md - Identify all relevant sections (concepts, entities, sources, comparisons).
- Read every relevant page. No skipping.
- If wiki coverage is thin, offer to supplement with web search.
- Synthesize a comprehensive answer with full citations.
- Always file the result back as a wiki page. Deep answers are too valuable to lose.
Token Discipline
Read the minimum needed:
| Start with | Cost (approx) | When to stop |
|---|---|---|
| hot.md | ~500 tokens | If it has the answer |
| index.md | ~1000 tokens | If you can identify 3-5 relevant pages |
| 3-5 wiki pages | ~300 tokens each | Usually sufficient |
| 10+ wiki pages | expensive | Only for synthesis across the entire wiki |
If hot.md has the answer, respond without reading further.
Index Format Reference
The master index (
wiki/index.md) looks like:
## Domains - [[Domain Name]]: description (N sources) ## Entities - [[Entity Name]]: role (first: [[Source]]) ## Concepts - [[Concept Name]]: definition (status: developing) ## Sources - [[Source Title]]: author, date, type ## Questions - [[Question Title]]: answer summary
Scan the section headers first to determine which sections to read.
Domain Sub-Index Format
Each domain folder has a
_index.md for focused lookups:
--- type: meta title: "Entities Index" updated: YYYY-MM-DD --- # Entities ## People - [[Person Name]]: role, org ## Organizations - [[Org Name]]: what they do ## Products - [[Product Name]]: category
Use sub-indexes when the question is scoped to one domain. Avoid reading the full master index for narrow queries.
Filing Answers Back
Good answers compound into the wiki. Don't let insights disappear into chat history.
When filing an answer:
--- type: question title: "Short descriptive title" question: "The exact query as asked." answer_quality: solid created: YYYY-MM-DD updated: YYYY-MM-DD tags: [question, <domain>] related: - "[[Page referenced in answer]]" sources: - "[[wiki/sources/relevant-source.md]]" status: developing ---
Then write the answer as the page body. Include citations. Link every mentioned concept or entity.
After filing, add an entry to
wiki/index.md under Questions and append to wiki/log.md.
Gap Handling
If the question cannot be answered from the wiki:
- Say clearly: "I don't have enough in the wiki to answer this well."
- Identify the specific gap: "I have nothing on [subtopic]."
- Suggest: "Want to find a source on this? I can help you search or process one."
- Do not fabricate. Do not answer from training data if the question is about the specific domain in this wiki.
