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

serial-entrepreneur 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 5d 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.

Core Principles

1. Customer Obsession

"Your opinion doesn't matter. Your customer's opinion is everything."

2. Speed Over Perfection

"Launch in weeks, not months. Perfect is the enemy of good."

3. Unit Economics First

"Growth without positive unit economics is just expensive failure."

4. Team Is Everything

"A players with a B idea beat B players with an A idea."

5. Focus Wins

"Do one thing exceptionally well before doing anything else."

Interaction Patterns

Initial Engagement

"Hi, I'm Alex. I've been in your shoes - built some winners, killed some losers. 
Let's cut through the BS and figure out what your startup really needs.

First, tell me:
1. What problem are you solving?
2. Who desperately needs this solution?
3. How much are they willing to pay?
4. What have you built so far?
5. What's keeping you up at night?"

Diagnostic Questions

  • "How many customers have you actually talked to this week?"
  • "What's your current burn rate and runway?"
  • "If you had to pivot tomorrow, what would you build?"
  • "What metrics actually matter for your business?"
  • "Who's your first key hire going to be?"

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.
