Not a concept to apply — a method to run. **Lineage:** [de Bono](https://en.wikipedia.org/wiki/Edward_de_Bono) · [Meadows](https://en.wikipedia.org/wiki/Donella_Meadows) · [Altshuller](https://en.wikipedia.org/wiki/Genrich_Altshuller) · [Minto](https://en.wikipedia.org/wiki/Barbara_Minto) · [Goldratt](https://en.wikipedia.org/wiki/Eliyahu_M._Goldratt) · [Tetlock](https://en.wikipedia.org/wiki/Philip_E._Tetlock) · [Klein](https://en.wikipedia.org/wiki/Gary_Klein) · [Mill](https://en.wikipedia.org/wiki/John_Stuart_Mill) · [Kant](https://en.wikipedia.org/wiki/Immanuel_Kant) · [Aristotle](https://en.wikipedia.org/wiki/Aristotle) · [Noddings](https://en.wikipedia.org/wiki/Nel_Noddings) · [Rawls](https://en.wikipedia.org/wiki/John_Rawls) · [Sun Tzu](https://en.wikipedia.org/wiki/Sun_Tzu) · [Clausewitz](https://en.wikipedia.org/wiki/Carl_von_Clausewitz) · [Musashi](https://en.wikipedia.org/wiki/Miyamoto_Musashi) · [Nash](https://en.wikipedia.org/wiki/John_Forbes_Nash_Jr.) · [Axelrod](https://en.wikipedia.org/wiki/Robert_Axelrod) · [Vickrey](https://en.wikipedia.org/wiki/William_Vickrey) · [Shapley](https://en.wikipedia.org/wiki/Lloyd_Shapley) · [Spence](https://en.wikipedia.org/wiki/Michael_Spence) ``` npx @human-avatar/skills-for-humanity ``` Run again to update.

Every skill pauses before running and asks how deep you want to go. ``` /think │ ├── Think Sharper │ ├── /logic │ │ ├── /logic-check │ │ ├── /logic-argument-validation │ │ ├── /logic-causality-mapping
