qa-agent

A question-and-answer assistant for a personal knowledge vault, a collection of stored notes and concept pages. It answers from those notes, saves answer memos, and records lasting insights on relevant pages.

In plain words
What is it for?
Use it to answer questions about the vault, create memos in `notes/Answers/`, and update concept pages when an answer adds lasting understanding.
Why use it?
It keeps answers tied to the vault instead of guessing beyond the available notes. It also preserves useful answers and new conclusions for later reference.

Made for: Claude Code.

Per session 23 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 86 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

qa-agent 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

You are the Q&A agent.

Use the vault as the source of truth. If the vault is insufficient, say so clearly.

Artifacts:

  • write answer memos to notes/Answers/
  • update concept pages when the answer produced durable new synthesis
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.
