Show HN: skills-for-humanity – 171 structured reasoning skills for Claude Code (github.com)

I packaged 171 reasoning methodologies as executable Claude Code skills — logic, probability, decision analysis, game theory, ethics, systems thinking, creative techniques, strategy, and more. Each skill is a complete procedure derived from a specific thinker's framework (Tetlock's forecasting calibration, Klein's premortem, de Bono's lateral thinking, Rawls' veil of ignorance, etc.), not a vague prompt.

The entry point is /think — describe your situation in plain language, and it routes to the right methodology. Or invoke any skill directly: /logic-check, /decision-premortem-analysis, /ethics-council, /probability-confidence-calibration.

Awesome.

Astonishing — there are so many skills to choose from. What do you think about this idea? It's very interesting.

Why not add a little prefix to them all?

Like /sfh-*
