From b3598adc55263278a4f1a72bfaef473ec2b08eb8 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Fri, 3 Apr 2026 23:03:33 -0700 Subject: [PATCH] feat: interactive /plan-devex-review with persona, benchmarks, and forcing questions Complete rewrite of the DX review skill to match CEO/eng review depth. New flow: investigate (persona, empathy, competitors, magical moment, journey tracing) then force decisions, then score with evidence. Three modes: DX EXPANSION, DX POLISH, DX TRIAGE. 20-45 interactive STOP points vs 10-12 before.
