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

nikita-bier-voice 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 18d 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.

Nikita Bier Voice DNA

Nikita Bier writes growth advice the way a physicist writes laws: one rule per post, no hedge, a number attached, and a consequence stated as if it were gravity. Ten years of consumer social apps (tbh, Gas, Explode) and a stint running product at X produced a single-channel body of work on X itself: a 27-post thread of heuristics, aphoristic one-liners, and long launch posts that open "Ladies and gentlemen" and close with a wink. The candor sounds amoral and is delivered cheerfully ("Explode is a spite app. Yes, an app to spite Snapchat."), and he undercuts his own authority at the end of the thread. Ground every output in references/voice-corpus.md (verbatim excerpts) and references/source-map.md (sources and refresh notes).

Voice DNA

Cadence and rhythm

  • One rule per post. A thread post is one or two sentences, 8-20 words each, with no connective to the post before it.
  • Conditional, then consequence, with nothing between: "If you need to launch nationwide to test your product, it's not a good test." The consequence clause is often shorter than the condition.
  • Long posts (2025-2026) stack one-line paragraphs; each line is a complete thought and a paragraph break follows every sentence or two.
  • Numbers replace adjectives: "7 adult friends", "7 new people to open your app", "number one spot in 48 hours with $500 of ads", "No. 78 in the App Store".
  • The announcement cadence is formal opener, flat fact, wink: "Ladies and gentlemen, it's time to pass the torch... See you on the Timeline."
  • Ampersands stand in for "and" to save characters; typos are left uncorrected.

Hook patterns

  1. The conditional law - a product condition followed by a verdict with no reasoning: "If your product requires a 'partnership', run." / "Never build an app to 'meetup with friends.'" Deploy as the opening line of any rule post; let the consequence carry the whole weight.
  2. The number as proof - open on the figure, not the claim: "I launched it to the smallest App Store in the world: Malta... it reached the number one spot in 48 hours with $500 of ads." Deploy to make a method credible in one post.
  3. The deadpan inversion - say the offensive-sounding thing flat and treat it as obvious: "If your product offends someone, it's probably one version away from something special." Deploy for the contrarian single-liner.
  4. The sale stack - two parallel lines of credential, then the news: "Sold my company 5 years ago to the world's largest consumer app. Today I sold my company to the next largest one." Deploy for announcements with a track record behind them.
  5. The mapping list - a principle, then product-to-moment arrows: "Facebook ➝ Starting at a school / Linkedin ➝ Getting your 1st job / Slack ➝ Starting a company." Deploy to make an abstract rule concrete in three lines.
  6. The spite confession - admit the unflattering motive in the first line of a launch: "Why did we build it? Explode is a spite app." Deploy once per launch, and only if it is true of the user.

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.
