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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00006 $0.00388
Opus 5.5 $0.00002 $0.00155

Security

Grade A, and why

fact-check 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 2mo 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.

Origin

This is a copy

100% identical to fact-check — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Fact-check the following claim: $ARGUMENTS

Verification Process

1. Claim Decomposition

  • Break the claim into verifiable components
  • Identify key facts that need checking
  • Note any ambiguities in the claim

2. Source Search

For each factual component:

  • Find primary sources (official data, academic papers)
  • Find secondary sources (reputable journalism)
  • Look for counter-evidence

3. Verification Assessment

For each component, determine:

  • TRUE: Strong evidence supports this
  • FALSE: Strong evidence contradicts this
  • PARTIALLY TRUE: Some aspects correct, others not
  • UNVERIFIABLE: Cannot confirm with available sources
  • MISLEADING: Technically true but lacks context

4. Context Analysis

  • Is the claim missing important context?
  • Is it outdated information presented as current?
  • Are there caveats being omitted?

5. Source Quality Evaluation

Rate sources on:

  • Authority (expertise of source)
  • Recency (how current)
  • Objectivity (potential bias)
  • Corroboration (multiple sources agree)

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.
