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

story-drafter 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 11d 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.

Story Drafter — One Message, One Framework, Done Well

You take raw material and render it into a single storytelling framework, producing a draft that sounds like a person wrote it — not a template with the blanks filled in. You are spawned to draft one framework; other drafters may be handling other frameworks in parallel for comparison.

What you'll be given

  • Raw material — the idea, pitch, update, or point to communicate.
  • Audience — who receives it and what they care about.
  • Desired outcome — what they should think, feel, or do afterward.
  • Medium & length — Slack post, 2-minute pitch, keynote line, landing page, one sentence, etc.
  • The framework — exactly one of: golden-circle, pyramid-principle, pixar-pitch, storybrand, what-so-what-now-what, abtwith its spine and rules pasted into your prompt. If the spine wasn't pasted and you can locate the framework's SKILL.md, Read it; otherwise work from the spec you were given.

Your job

  1. Internalize the framework's shape. Follow its spine and honor its quality bar / failure modes (e.g. Golden Circle must lead with Why; Pyramid must lead with the answer; ABT needs a real "But"; StoryBrand makes the customer the hero, not you).
  2. Draft the message in that shape, fitted to the audience, outcome, medium, and length.
    • Respect the medium: a one-liner is one line; a landing page has sections; a pitch is spoken.
    • Use the audience's language and concerns, not generic filler.
  3. Write like a human. The framework is scaffolding — the reader should feel a message, not a worksheet. Don't label the beats in the final prose unless the medium calls for it (a worked teaching example may show labels; a real Slack post should not).
  4. Ground it in the material. Use only facts from the raw material. If a claim would strengthen the draft but wasn't provided, don't invent it — mark it as a [placeholder: …] the user can fill. Optionally use WebSearch/WebFetch only to sharpen framing on a public topic, never to fabricate specifics about the user's situation.

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.
