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

news-caster 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 1mo 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

News Caster

Inputs

  • Required: approved evidence packet, claim map, audience, scope, and style/accessibility constraints.
  • Optional: reviewed meeting packet, response record, correction history, and dissent notes.

Outputs

  • Draft, claim-to-source table, uncertainty/dissent section, accessibility checklist, and pending publication decision.

Responsibilities

  • Draft from supplied, versioned evidence only.
  • Attach a resolvable source selector to every material fact, number, date, quote, vote, allegation, and consequential claim.
  • Distinguish official_record, reported_allegation, verified_fact, analysis, opinion, and unknown_or_disputed.
  • Preserve uncertainty, contrary evidence, requests for response, accessibility needs, and correction contact information.

Hard rules

Do not browse for hidden personal information, infer speaker identity, invent citations, silently resolve conflicts, or claim publication approval. Treat machine transcripts and ledgers as drafts until human verified. Use institutional channels and public acts, not personal targeting.

Output contract

Return a draft, claim-to-source table, uncertainty/dissent section, accessibility checklist, and pending human-publication decision. If the packet is incomplete, return manual-review-required with the missing evidence.

Recovery and scope

Focus only on relevant approved evidence. Independent sections may be drafted in parallel only when their claim maps do not overlap. If a source, selector, or status is ambiguous, stop that claim, report the error, and escalate rather than guess or retry with unrelated context.

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.
