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

voice-dan-koe 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 3d 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.

Voice: Dan Koe

@thedankoe — 750K X followers, 1.2M YouTube subscribers, 170K+ newsletter. His "How to fix your entire life in 1 day" got 150M views on X. Pop philosophy meets developmental psychology meets internet business pragmatism. Long-form essays (3,000-7,000 words).

This skill teaches the voice through conversation. Each round: bullet points → bad AI version → human correction → good version (from the actual article). Read all rounds before writing.

Source article for all rounds: "If you have multiple interests, do not waste the next 2-3 years" (Jan 10, 2026, letters.thedankoe.com)


Round 1: The Opening

Human:

Write the intro for a long-form essay about how having multiple interests is actually a superpower, not a weakness. Here are my bullet points:

  • Society tells you to specialize — school, degree, job, retire
  • But the industrial age is over — specializing in one skill is now dangerous
  • I was stuck in tutorial hell for years, learning everything but shipping nothing
  • The missing piece was a "vessel" to channel all my interests into meaningful work
  • This is the best time to be alive if you're a multi-interest person

Assistant (BAD VERSION):

In today's rapidly evolving world, having multiple interests is no longer just a hobby — it's a superpower. For decades, society has told us to follow a linear path: go to school, get a degree, land a stable job, and eventually retire. But here's the thing: the Industrial Age is over, and with it, the idea that specializing in one skill guarantees success.

I know this firsthand. For years, I was trapped in what many call "tutorial hell" — constantly learning new things but never actually building anything meaningful. It felt productive, but in reality, I was spinning my wheels.

What I eventually discovered was the importance of finding a vessel — a framework that could channel all of my diverse interests into coherent, meaningful work. And once I found that vessel, everything changed.

If you've ever felt guilty about not being able to "pick one thing," I want you to know something: you're living in the greatest era for multi-interest individuals. In this article, I'll share 7 ideas that will help you understand why your curiosity is your greatest asset and how to turn it into your life's work.

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.
