What problem does it solve? Contributing to Zeus, a React Native Bitcoin/Lightning wallet, involves strict unwritten maintainer rules, change classification gates, and review conventions that are easy to violate, causing PR rejections, reverts, or even user fund loss. ## Core Features & Use Cases - Change Classification & Gates: Categorizes changes as funds-touching, storage-touching, UI-only, docs-only, dependency, or locales, and states the approval gate each requires before coding and before merge. - PR & Commit Conventions: Documents the mandatory PR template sections, commit message prefix style, ACK/tACK/NACK review vocabulary, and the four CI checks that run on every pull request. - Incident-Backed Rules: Explains the four maintainer non-negotiables (storage gating, revert-first near releases, no payment-path refactors, manual two-platform testing) with the real incidents that motivated them. - Use Case: Before opening a PR that edits locale files or touches the keychain settings blob, consult this Skill to learn that only locales/en.json may be edited and that storage changes require maintainer sign-off plus a written migration plan. ## Quick Start Ask how to classify and submit a change to the Zeus wallet, for example what approval is needed before editing storage migrations or payment code.
