What problem does it solve? Zeus has dozens of settings spread across a keychain blob, per-node fields, nested groups, and AsyncStorage flags, with defaults that differ between fresh installs and migrated users. This Skill gives you a verified catalog of every configuration axis so you can add, change, or look up a setting without causing data loss, shallow-merge bugs, or fresh-vs-migrated divergences. ## Core Features & Use Cases - Complete settings catalog: Every axis with its storage location, options, default value, and owning UI file, covering per-node fields, nested groups (privacy, display, payments, invoices, channels, swaps, POS, ecash), and flat LSP/embedded-node keys. - Add-a-setting checklist: A mandatory 10-step procedure covering typing, defaults, *_KEYS arrays, shallow-merge-safe updateSettings calls, locale strings, and migration requirements. - Divergence and deprecation tracking: Documents new-vs-migrated default differences (bimodalPathfinding, showMillisatoshiAmounts) and the five deprecated-but-retained flags that cannot be casually removed. - Use Case: You need to add a new payments setting. Load this Skill to find the right group, apply the spread-safe updateSettings pattern, add the English locale string, and determine whether a MOD_KEY migration and maintainer sign-off are required. ## Quick Start Load the zeus-config-and-flags skill and tell me where the setting I want to add or change should live and what its default value is.
