query

query is a command for coding agents from sk-lim19f/Hypomnema. It costs 38 tokens per session (494 once invoked), scanned A, original, MIT.

A wiki-query command searches saved project pages and notes, then combines the relevant information into an answer with links to its source pages. A wiki is a searchable collection of personal documentation.

In plain words
What is it for?
It is for answering questions from the wiki, recalling previous work, and finding context before starting a task.
Why use it?
It helps recover past decisions and project context without manually searching through every note.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

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 4d 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

You are running /hypo:query. Answer a question by searching the wiki and synthesizing from relevant pages.

What this does

  • Searches pages/ and projects/ for pages relevant to the query
  • Reads and cross-references the top matches
  • Synthesizes a grounded answer citing [[page-slug]] links

Step 1 — Understand the query

Ask the user what they want to know if it was not provided in the command invocation.


Bundled scripts here run via ${CLAUDE_PLUGIN_ROOT}/scripts/. To resolve that package root: if ${CLAUDE_PLUGIN_ROOT} is already an absolute path, use it; otherwise read pkgRoot from ~/.claude/hypo-pkg.json (only when non-empty and the target script exists under it); otherwise use the hypo@hypomnema (or legacy hypomnema@hypomnema) installPath in ~/.claude/plugins/installed_plugins.json; if none resolve, stop and tell the user to run hypomnema upgrade --apply or reinstall instead of guessing the cache layout.

Run full-text search:

node ${CLAUDE_PLUGIN_ROOT}/scripts/query.mjs \
  --q="<query terms>" \
  [--hypo-dir="<path>"] \
  [--limit=10]

Step 3 — Read relevant pages

Read index.md first to understand the page catalog, then read the top-scoring pages returned by the search script (up to 5).


Step 4 — Synthesize answer

Write a clear, concise answer that:

  • Cites source pages as [[slug]] links
  • Notes confidence level if any source is speculative
  • Flags if no relevant pages were found ("Hypomnema does not currently have a page on this topic.")

If the query surfaces a gap, offer to create a new page or run /hypo:ingest on a relevant source.


Step 5 — Offer follow-ups

After answering, suggest 1–2 related pages the user might want to read next.

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.
