From fc515daaefaa1cb28f749b521c0f2bcd029faf6a Mon Sep 17 00:00:00 2001 From: Jamie Taylor Date: Fri, 31 Oct 2025 19:35:16 +0000 Subject: [PATCH 1/3] feat(confirm): add command risk scoring to confirm prompts Integrate the new safety package to evaluate command risk before execution. The confirmation prompt now displays a colored risk level (high, medium, low) based on the assessment, helping users make informed decisions.
