From f2ca121a85236975fb8e18d29d50357e38187cd5 Mon Sep 17 00:00:00 2001 From: John Grubb Date: Mon, 14 Jul 2025 17:22:02 -0400 Subject: [PATCH 1/4] refactor(aws): Extract common CLI helper functions - Add _load_and_validate_config() to eliminate duplicate config loading - Add _get_aws_credentials() to centralize AWS credential extraction - Replace 4 instances of duplicate config loading logic across CLI commands -
