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

learn-verify 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 12d 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

Learn verify

Trust is engineered. Check the claim before it is taught as fact.

When to run

  • Empirical, historical, bibliographic, or API/tool claims
  • Named theorems, identities, or "standard facts" you cannot reconstruct
  • Anything you were about to present with unearned certainty

Skip a full search only when you can derive the statement in-session and the learner does not need an external citation. Still say that it was derived, not sourced.

Method

  1. Write the claim in one falsifiable sentence.
  2. Fetch or search primary-ish sources (paper, textbook, official docs, standard reference). Do not cite a URL you did not open.
  3. Quote or paraphrase the supporting line. Note edition / year if it matters.
  4. Mark disagreements. Prefer the source the field actually uses.
  5. Return a verdict.

Verdict

## Claim
…

## Verdict
confirmed | qualified | contradicted | unknown

## Sources
- <title> — <url or citation> — <what it says>

## Teach as
<one sentence the teacher may now say, with any hedge>

qualified = true under stated assumptions (dimension, characteristic, gauge, version).

unknown = do not teach it as fact. Say you could not verify.

Rules

  • No invented papers, quotes, or page numbers.
  • One claim per run. Batch only if they are the same fact in different words.
  • Write the verdict into the session file if a teach session is open.
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.
