vouch-ask

A question-answering command for a reviewed project knowledge base. It answers only from stored information and attaches a citation to each supported statement.

In plain words
What is it for?
Use it to ask about documented project knowledge, inspect supporting claims or records, and identify the closest available information when evidence is missing.
Why use it?
It prevents guesses from being presented as facts and clearly shows when the knowledge base cannot answer a question.

Made for: Claude Code.

Per session 15 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 245 The whole file, excluding the scripts and references it only reads on demand.

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

vouch-ask 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

/vouch-ask

Answer "$ARGUMENTS" using only reviewed knowledge from the vouch KB. Every statement in the answer must carry a [claim-id] or [source-id] citation.

Steps:

  1. Call kb_search with query: "$ARGUMENTS", then kb_context on the same query to assemble the working set.
  2. If the results answer the question, write the answer citing every claim id you relied on. Use kb_read_page for typed record detail (contacts, project records, followups).
  3. If the KB cannot support an answer, say so plainly and list the closest claims found. Do not fill gaps from your own knowledge — an uncited answer is worse than no answer.
  4. Only when the user explicitly asks about in-flight knowledge, list kb_list_pending items — each labeled UNREVIEWED — after the cited answer, never mixed into it.

Never call kb_approve. Never restate pending proposals as facts.

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.
