query

A read-only command for answering questions from a Markdown knowledge base. It finds relevant pages, follows linked pages one level deep, and cites the pages used in the answer.

In plain words
What is it for?
Use it to research a question within the vault, connect related pages, identify missing knowledge, and optionally save substantial reusable answers when explicitly approved.
Why use it?
It turns scattered notes into a sourced answer while showing where each claim came from. It also points out when the vault lacks information needed to answer fully.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 340 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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 2d 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.

What it actually says

/query

Answer a question by synthesizing from the vault. $ARGUMENTS is the question.

Steps

  1. Read wiki/index.md to understand what's available.

  2. Identify relevant pages by matching on titles, summaries, and implied tags.

  3. Read those pages. Follow [[wikilinks]] one level deep if needed for the question. Don't go deeper unless explicitly required.

  4. Synthesize a comprehensive answer:

    • Lead with a direct answer
    • Cite wiki pages inline using [[wikilinks]]
    • Show how pages connect when the answer spans multiple
    • Mention raw sources when cited in pages
  5. If the answer reveals a gap (sub-question the wiki can't fully answer), note it:

    💡 Gap noticed: no page exists for X. Consider /ingest or /compile to add it.

  6. If the answer is substantial and reusable (3+ paragraphs of synthesis), offer to save it:

    This answer is reusable. Save as a new wiki page in wiki/concepts/ or to output/?

  7. Do NOT modify any wiki files. /query is read-only. User must explicitly accept the save offer.

Rules

  • Cite everything.
  • Be honest about gaps — don't fabricate.
  • One level deep on wikilink following.
  • Prefer wiki over web search — trust curated knowledge first.
  • If the answer contradicts a wiki page, flag it and recommend /lint.
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.
