From 839a3eb5cc154852efcd5d34f1e7c76bf43f2621 Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Wed, 18 Feb 2026 07:22:51 +0000 Subject: [PATCH 1/2] docs: improve docstring coverage from 46% to 97% for public functions Added comprehensive docstrings to 19 public functions including: - API helpers (validate_profile_id, validate_folder_data) - Core sync functions (sync_profile, push_rules, warm_up_cache) - Folder management (create_folder, delete_folder, list_existing_folders) - Data fetching (fetch_folder_data, get_all_existing_rules) - Entry points (main, parse_args) All docstrings follow the existing style with clear purpose statements and parameter/return descriptions where appropriate.
