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

stoic-fortitude-and-resilience 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 6d 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.

Stoic Fortitude and Resilience

IRON. The word recurs across Stoic literature with a frequency that borders on obsession, and the reason is not metaphorical vanity. Iron is shaped in fire, hardened by hammering, made useful through processes that would destroy lesser materials. Comfort, as Seneca observed with characteristic bluntness, has never hardened anything. Cato the Younger walked Rome barefoot and bareheaded in rain and heat -- not because he lacked the means for sandals and a parasol, but because he was training his soul against the day when fortune would strip him of everything except his character. That day came, as it always does. Cato was ready. The question for the entrepreneur is not whether adversity will arrive. It is whether the founder will meet it as raw ore or as tempered steel.

"I judge you unfortunate because you have never lived through misfortune. You have passed through life without an opponent -- no one can ever know what you are capable of, not even you." -- Seneca, On Providence


The Framework

Stoic fortitude is not the grim endurance of someone who merely survives. It is a trained capacity to metabolise difficulty into strength -- what Nassim Taleb would later call anti-fragility, but which the Stoics articulated two millennia earlier without the neologism. The framework rests on four pillars.

Pillar 1: The Inner Citadel

Marcus Aurelius returned again and again to the concept of an impenetrable inner fortress -- a domain of reasoned choice that no external force can breach. "The mind freed from passions is an impenetrable fortress -- a person has no more secure place of refuge for all time." The fortress falls only through internal betrayal: when fear, greed, or despair open the gates from within.

For entrepreneurs, the Inner Citadel is the capacity to separate external events (a lost client, a failed fundraise, a competitor's surprise move) from internal judgement. The event is neutral. The interpretation -- catastrophe or curriculum -- is a choice.
