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

claim-verification-checklist 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 8d 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.

Claim Verification Checklist

What This Skill Does

Generates a point-by-point checklist of every verifiable claim in a draft article, categorized by claim type and accompanied by the specific evidence needed to confirm each one.

When To Use This Skill

  • A story is close to publication and needs a systematic fact-check before the editor or legal team sees it
  • You are the assigning editor and want to hand a reporter a clear list of what still needs to be verified
  • You have inherited a draft from another writer and need to understand what is sourced and what is asserted
  • You want to ensure no factual claims slip through on deadline without a documented verification method

What You Need To Provide

Required: The full text of the draft article or a detailed section-by-section summary Optional: A note on which claims are already verified (so the checklist can mark them as such); the publication's fact-checking standard (minimal, standard, or rigorous); the story type (news, investigation, profile, feature)

How the Assistant Approaches This

  1. Reads the draft and extracts every claim that is factually verifiable — distinguishing factual assertions from opinions, characterizations, and attributed quotes
  2. Categorizes each claim by type: statistical, biographical, chronological, attribution (quote or paraphrase), official record, scientific, or legal
  3. For each claim, specifies the minimum evidence standard needed for verification — primary source, secondary corroboration, expert confirmation, or documentary proof
  4. Flags highest-risk claims: those that are specific, potentially defamatory, or that directly contradict public statements by named individuals
  5. Closes with a "Next Step" note: which High-risk item to verify first, estimated time to clear the checklist, and whether libel-check-brief should be run alongside for any drafts containing allegations against named individuals

Output Format

Numbered checklist. Each item: Claim (exact quote from draft) | Claim Type | Required Evidence | Risk Level (Low / Medium / High). Grouped by section of the article. Followed by a Summary section noting total claim count, High-risk count, and items already marked as verified. Length scales with article length — typically 400–800 words for a 1,500-word article. Output ends with a "Next Step" note: which High-risk claim to verify first, how long the full check is likely to take, and whether libel-check-brief should be run on the same draft.
