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

founder-led-sales 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 13d 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.

Founder-led sales (close your first customers yourself)

Nobody can sell it before you can. The first ten deals are not a hire, they are how you learn what you are actually selling and to whom. Do them yourself, badly at first, until the motion repeats.

Use this when: developers love it and live in the free tier but nobody pays, you have never sold anything and freeze on the actual conversation, every deal dies on "let me think about it," or you are tempted to hire a salesperson to do the part you have not figured out yet.

The core idea

market-to-devs-sell-to-buyers told you who to sell to (the dev adopts, the boss pays). pricing set the number. This is the part nobody warns technical founders about: actually doing it. And it is not slimy. Selling a dev tool well is discovery plus helping a champion get budget. You are not convincing anyone of anything false, you are finding the people who already have the pain and making it easy for them to say yes.

One rule under all of it: do this yourself until it repeats. You cannot outsource a motion you have not cracked. Founders who hire a rep at deal one hire someone to fail at a job that does not exist yet.

Every real deal has four things

If any one is missing, it is not a deal, it is a conversation. Your job is to find out which is missing.

  • A champion. Someone who uses it, loves it, and will fight for it inside their company. Usually the developer who adopted you.
  • A buyer. Someone with budget. Often not the champion.
  • A pain with a cost. Not "this is nice." A problem costing them money, time, or risk right now.
  • A trigger. A reason to act now, not next quarter. An incident, an audit, a deadline, a scaling wall.

The motion

1. Start with who is already engaged. Do not cold-blast strangers. Your first customers are hiding in your own usage data: the team with three seats on the free tier, the person who filed four issues, the account that hit a limit. They have already shown you the pain.
