Diagnose reproducible failures and restore established behavior. Investigate missing facts; unresolved changes to user experience belong to product requirements.
Turn visual goals, brand context and scenarios into a reasoned Design Brief. Use when visual or interaction rules change, not to restore established behavior.
Create prototypes, wireframes and interaction states when a visual artifact will reduce uncertainty. Optional for new or changed designs; not required for routine maintenance.
Implement a defined product or maintenance change, integrate results and verify relevant behavior. Use bug-fixer for unknown failure causes; independent review depends on concrete risk.
Plan a clear outcome as a short task or dependent phases. Reuse active plans; use phases when requested or when deliverables need separate acceptance.
Write a bounded, recoverable Goal with measurable acceptance only when the user explicitly requests a persistent or long-running goal. Never create unlimited retry loops.
Turn an idea or product change into testable requirements. Use when intended user behavior or scope is unresolved; skip repeated interviews for already confirmed changes.
Maintain current project knowledge, capture explicit design and release conventions during ordinary work, reconcile superseded decisions, and retire obsolete tasks without losing historical evidence. Use for scoped knowledge upkeep or authorized documentation…
