When to Use Use this skill when: - Adding screens or menu options - Changing key bindings or navigation flows - Updating list rendering and detail views --- UX Rules 1. Keyboard behavior must be consistent across screens. 2. Empty/loading/error states must be explicit and readable. 3. Long lists require clear truncation/scroll cues. 4. Back navigation should preserve context predictably. --- Test Rules - Add tests for new key transitions. - Add tests for new rendering branches. - Add tests for async commands/data-loading paths. No TUI behavior change ships without deterministic tests. ---
