What it does
Query is an agent skill from jackwener/llm-wiki. Answer questions from an LLM Wiki vault. Use whenever the user invokes /query, asks what the wiki knows about a topic, or needs an evidence-grounded synthesis of existing wiki pages and their links.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering LLM wikis. The repository describes itself as: Agent-native persistent knowledge management — compile knowledge once, query forever. The licence is Apache-2.0.
When your agent uses it
- The user invokes /query
- Asks what the wiki knows about a topic
- Needs an evidence-grounded synthesis of existing wiki pages and their links
Example prompts
- “/query”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Find the vault and read wiki-purpose.md; confirm that the question falls
- Search with llm-wiki search "". Use --bm25-only only when
- Read the matched pages and follow relevant [[wikilinks]] and ## Related
- Give a direct answer grounded in the pages. Cite pages as [[slug]], state
- If the wiki lacks enough evidence, say so and suggest specific material to
What it can do on your machine
Read from SKILL.md and the folder at commit cd54666. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Query loads about 479 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 219 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
The full file from jackwener/llm-wiki at commit cd54666, republished under its Apache-2.0 licence (© jackwener). 219 words, ~479 tokens.

- Answer questions from an LLM Wiki vault. Use whenever the user invokes `/query`, asks what the wiki knows about a topic, or needs an evidence-grounded synthesis of existing wiki pages and their links.
Query an LLM Wiki
Answer from the maintained wiki, then capture only durable synthesis that makes future queries more useful.
Workflow
- Find the vault and read
wiki-purpose.md; confirm that the question falls within its intended scope. Readwiki-schema.mdfor local conventions. - Search with
llm-wiki search "<question>". Use--bm25-onlyonly when vector search is unavailable or inappropriate. Scanwiki/for exact terms if needed. - Read the matched pages and follow relevant
[[wikilinks]]and## Relatedsections. Use the graph as context rather than treating search ranking as the answer. - Give a direct answer grounded in the pages. Cite pages as
[[slug]], state uncertainty, distinguish evidence from inference, and surface conflicts or gaps instead of guessing. - If the wiki lacks enough evidence, say so and suggest specific material to ingest. Do not fill gaps from unsaved external knowledge.
When knowledge should compound
Write back only a non-trivial, high-confidence synthesis: for example, a new connection among at least three pages, a resolved contradiction, or a useful comparison absent from all source pages. Do not create a page for a simple lookup or speculative conclusion.
For a durable synthesis, create a focused wiki page with complete frontmatter:
---
title: Synthesis Title
description: One-line summary
tags: [synthesis]
sources: [contributing-page-slugs]
source_type: query-synthesis
created: YYYY-MM-DD
updated: YYYY-MM-DD
---Link it to the contributing pages, append a query entry to wiki-log.md,
and run llm-wiki sync. Do not modify anything under sources/.
