From 8ab74e053ba74e353b7dd9fa9b4d3cf77879b4f5 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Tue, 17 Mar 2026 17:07:36 -0700 Subject: [PATCH 1/2] =?UTF-8?q?feat:=20cognitive=20patterns=20for=20plan-r?= =?UTF-8?q?eview=20skills=20=E2=80=94=20latent=20space=20activation?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enrich /plan-ceo-review, /plan-eng-review, and /plan-design-review with researched cognitive patterns from Bezos, Grove, Munger, Horowitz, Altman, Rams, Norman, Zhuo, Gebbia, Larson, McKinley, Brooks, Beck, and Majors.
