wiki-query

wiki-query is a skill for Claude Code from flsteven87/llm-wiki-mcp. It costs 243 tokens per session (1,517 once invoked), scanned A, original, MIT.

A skill for answering questions from a Karpathy-style LLM wiki, a collection of linked pages used as an AI-readable knowledge base. It searches relevant pages, reads them, and produces an answer with citations.

In plain words
What is it for?
For researching an existing wiki, comparing its pages, answering questions with citations, and optionally filing genuinely new analyses back into the wiki.
Why use it?
It helps the agent combine information from several wiki pages instead of relying on chat memory. New comparisons or connections may also be saved as synthesis pages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wiki-query scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

wiki-query

Answer a question against an existing Karpathy-style LLM wiki. The pattern this skill follows is described in https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f.

Karpathy's query description, verbatim:

You ask questions against the wiki. The LLM searches for relevant pages, reads them, and synthesizes an answer with citations.

And on filing answers back:

good answers can be filed back into the wiki as new pages. A comparison you asked for, an analysis, a connection you discovered — these are valuable and shouldn't disappear into chat history.

Filing is a judgment call, not an automatic step. Pure fact lookup or restatement of an existing page stays in chat. Cross-page analyses and new connections earn a page.

Prerequisites

  • A wiki exists. If not, run wiki-init first.
  • The llm-wiki-mcp server is wired into this session. If wiki_inventory is not callable, tell the user to add the server to their MCP client config and restart.

Pre-flight

Read CLAUDE.md. This is the authoritative schema — page categories, frontmatter fields, link conventions, and operation vocabulary. The user may have evolved it since wiki-init. Honor the current state, not the defaults.

Flow

1. Scope

wiki_inventory()

No scan_for argument — this is a cheap call that returns every page's slug, frontmatter, body length, and computed in/out links. Combine it with a host Read of index.md to pick candidate slugs. Prefer pages whose title, tags, or category directly match the question. When in doubt, widen the candidate set — reading is cheap.

2. Read

wiki_read(slug=...)

Pull the full body of each candidate. If a page cites a neighbor ([[other-slug]]) that clearly bears on the question, widen and read it too. Two or three reads are normal; ten means the question is too broad and you should narrow it with the user first.

3. Synthesize with citations

Write the answer in the primary language declared in CLAUDE.md. Cite every non-trivial claim with [[slug]] pointing at the page the claim came from. Only cite slugs that appeared in the pages list returned by step 1 — this is the deterministic guarantee that your citations are not hallucinations. If a claim deserves a citation but no page supports it, say so explicitly ("the wiki does not currently cover X") rather than inventing a slug.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
