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

building-thinking-strength 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.

Building Thinking Strength

FOUR PILLARS. Clear thinking requires four internal muscles -- and most people exercise none of them. The Clear Thinking framework moves beyond the diagnostic question (what hijacks your thinking?) to the constructive one (what makes thinking resistant to hijacking?). The answer is not intelligence, nor education, nor access to better information. The answer is four disciplines that function like load-bearing pillars: self-accountability, self-knowledge, self-control, and self-confidence. Remove any single pillar and the structure collapses under pressure. Strengthen all four and decisions begin to compound in the right direction, because the person making them has become structurally harder to deceive -- especially by themselves.

The distinction from Kahneman's dual-process model is important. Kahneman describes the cognitive architecture -- fast and slow processing. The framework describes the character architecture -- the traits that determine whether a person can actually engage slow processing when it matters, or whether they will default to autopilot despite knowing better. Many founders can explain System 2 thinking fluently and still fail to practise it, because they lack the self-accountability to own their errors, the self-knowledge to see their blind spots, the self-control to resist the emotional impulse, or the self-confidence to act against consensus. Strength, not knowledge, is the bottleneck.


The Framework

Pillar 1: Self-Accountability

Self-accountability is the practice of owning outcomes -- all of them -- regardless of whether external factors contributed. The formulation is deliberately uncompromising: "No one cares about your excuses as much as you do. In fact, no one cares about your excuses at all, except you."

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.
