wiki-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.

Transport (v1.7+)

Reads should prefer the same transport the rest of the plugin uses. Consult .vault-meta/transport.json (auto-created by bash scripts/detect-transport.sh) and use the preferred entry:

• cli — obsidian-cli read "$VAULT" "$NOTE" and obsidian-cli search "$VAULT" "<query>" (Obsidian-native ranking); see skills/wiki-cli/SKILL.md
• mcp-obsidian / mcpvault — mcp__obsidian-vault__read_note, search_notes; see skills/wiki/references/mcp-setup.md
• filesystem — Claude's Read and Glob/Grep tools (final floor; always works)

Full decision tree: wiki/references/transport-fallback.md. Quick mode (hot.md only) is transport-agnostic — always uses Read.

Retrieval (v1.7+)

If wiki-retrieve is feature-detected — [ -x scripts/retrieve.py ] && [ -d .vault-meta/chunks ] && [ -f .vault-meta/bm25/index.json ] — Standard and Deep modes consult it BEFORE the legacy hot→index→drill chain:

python3 scripts/retrieve.py "<the user's question verbatim>" --top 5

Output is JSON with a candidates array. Each candidate has absolute_path to the source page, a snippet, and bm25_score + rerank_score. Read the cited pages (using the transport selector from §Transport above) and synthesize with chunk-level citation.

If retrieve.py exits 10 (feature not provisioned), or any step in the pipeline errors, fall back to the v1.6 legacy read order described in the Standard/Deep workflows below — no user-visible breakage.

Quick mode always skips retrieval (hot.md only — keeps the ~1,500 token budget intact).

Full spec: skills/wiki-retrieve/SKILL.md. Setup: bash bin/setup-retrieve.sh. The legacy read-order workflows below remain authoritative when wiki-retrieve is not installed.

Query Modes

Three depths. Choose based on the question complexity.

Quick Mode

Use when the answer is likely in the hot cache or index summary.

1. Read wiki/hot.md. If it answers the question, respond immediately.
2. If not, read wiki/index.md. Scan descriptions for the answer.
3. If found in index summary, respond and do not open any pages.
4. If not found, say "Not in quick cache. Run as standard query?"

Do not open individual wiki pages in quick mode.

Standard Query Workflow

1. Read wiki/hot.md first. It may already have the answer or directly relevant context.
2. Read wiki/index.md to find the most relevant pages (scan for titles and descriptions).
3. Read those pages. Follow wikilinks to depth-2 for key entities. No deeper.
4. Synthesize the answer in chat. Cite sources with wikilinks: (Source: [[Page Name]]).
5. Offer to file the answer: "This analysis seems worth keeping. Should I save it as wiki/questions/answer-name.md?"
6. 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."

1. Read wiki/hot.md and wiki/index.md.
2. Identify all relevant sections (concepts, entities, sources, comparisons).
3. Read every relevant page. No skipping.
4. If wiki coverage is thin, offer to supplement with web search.
5. Synthesize a comprehensive answer with full citations.
6. Always file the result back as a wiki page. Deep answers are too valuable to lose.

Token Discipline

Read the minimum needed:

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:

1. Say clearly: "I don't have enough in the wiki to answer this well."
2. Identify the specific gap: "I have nothing on [subtopic]."
3. Suggest: "Want to find a source on this? I can help you search or process one."
4. Do not fabricate. Do not answer from training data if the question is about the specific domain in this wiki.
