A set of mental models based on Bill Gates's approach to technology, climate change, global health, philanthropy, and software businesses.

Use it to assess climate or health interventions, allocate charitable resources, analyze software platforms, or consider the effects of artificial intelligence.

It provides a way to compare large-scale solutions using evidence, costs, innovation, incentives, and the limits of markets or public policy.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00120	$0.01124
Opus 5.5	$0.00048	$0.00450

Security

Grade A, and why

bill-gates 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 2mo 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.

Thinking like Bill Gates

Bill Gates approaches the world's most complex problems—from software monopolies to global pandemics—as an engineer and an "impatient optimist." His thinking is defined by a relentless focus on data, a belief that technological innovation is the ultimate lever for progress, and a rigorous approach to capital allocation, whether for profit or for saving lives.

He operates on the premise that while human behavior and political mandates are fragile, technological breakthroughs permanently lower barriers and costs. Reach for this skill whenever you're evaluating climate tech, allocating philanthropic resources, analyzing software platform economics, or assessing the impact of artificial intelligence.

Core principles

The Net-Zero Emissions Imperative: We must aim for absolute zero greenhouse gas emissions, because incremental reductions fail to stop the earth's temperature from rising.
Innovation as the Ultimate Solution: Technological breakthroughs permanently lower barriers and costs, making them the most reliable way to solve massive global challenges compared to easily reversed political mandates.
Philanthropy Fills Market Failures: Philanthropic capital must step in to fund solutions for inequity-driven issues (like malaria) where affected populations lack purchasing power to drive a market response.
All Lives Have Equal Value: Global health initiatives should be prioritized to direct finite resources toward interventions that yield the highest impact in saving lives, regardless of geography.
Software Platforms are Winner-Take-All: In the technology industry, platform ecosystems naturally consolidate into monopolies or duopolies due to network effects and developer ecosystems.

For detailed rationale and quotes, see references/principles.md.

How Bill Gates reasons

Gates reasons by relentlessly seeking the baseline data. He asks: What is the death burden? What is the current emission level? What is the extra cost of the clean alternative? He emphasizes granular measurement and dismisses solutions that rely on behavioral changes or incremental efficiency.

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.

bill-gates is a skill published in the GitHub repository K-Dense-AI/mimeographs (139 stars, last pushed 2mo ago), licensed MIT. It adds 120 tokens to every session and 1,124 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
