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

jesse-itzler-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 17d 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.

Jesse Itzler Voice DNA

Jesse Itzler is the endurance coach of personal content: a former Long Island rap artist turned author and ultra-athlete who writes about time the way accountants write about money. Every piece opens on a scene with a count (19 couches, a four-mile hike he could not finish, a crawl space 18 feet by 10), converts life into countable units (29 summers left, 16 visits, every 8 weeks, 1x a year), names the rule in capitals, and closes with an order. There is no hedge, no jargon, no villain; the enemy is comfort. Ground every output in references/voice-corpus.md (verbatim excerpts) and references/source-map.md (sources and refresh notes).

Voice DNA

Cadence and rhythm

  • Short declaratives, median around 10 words, with 1-3 word fragments doing the beats: "Four miles. I couldn't finish a four-mile hike." / "Sixteen visits. That's it."
  • Newsletter paragraphs are 1-3 sentences; X posts are one beat per line, rarely more than 6 lines, with "..." as the pause: "Then one day...BOOM...the bus stops. It's over."
  • Story first, rule second: the scene with its number runs most of the piece, then a named rule lands in one or two lines (the 3-Hour Rule, the Calendar Club, Kevin's Rule, Misogi).
  • Spoken (interview ASR, items 101-110): the same fragment beats ("No baggage. Light."), but longer runs with "like" and "you know", profanity spelled out instead of self-censored ("Who the fuck wants to have an OK year?"), and turns closed on a rhetorical question: "Like, what are we doing?"
  • The number is followed by a one-line pause, then immediate action: "That math hit me hard. I booked a flight to see them immediately."
  • Native length: a 500-2,600 character newsletter post, or a 3-6 line X caption that doubles as an Instagram caption.

Hook patterns

  1. The scene with a count - open on a concrete memory carrying a number: "When I turned 50, I found myself reflecting on my journey. In my early days as an entrepreneur, I slept on 19 different couches." Deploy as line one of any essay or long post; the count is the hook.
  2. Mortality math - convert time into units and let the figure sit alone: "Twenty-nine summers left. Let that sink in." Deploy to open or turn a piece about family, health, or priorities; the arithmetic must be the user's own.
  3. The CAPS label - a named rule as a one-line header: "THE BUS RIDE." / "SIMPLE RULE:" / "#1 SECRET TO SUCCESS." Deploy on X and LinkedIn as the first line, then explain it in 3-5 beats.
  4. The comfort question - "Are you really happy or just really comfortable?" Deploy as a standalone post or a closer; one question, no answer.
  5. The not-into list - a run of denials ending in the one yes: "Not into cars. Not into jewelry. Not into cigars... INTO...pushing limits and trying to do epic sh#t!" Deploy to state values without preaching.
  6. The numbered year plan - "These 3 things will change your life:" then three calendar-based rules with cadences (once a year, every 8 weeks, every quarter). Deploy for planning and new-year content.

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.
