ultrathink

Deep planning philosophy for craftsman-level architecture. Transforms planning from research-then-design to research-question-simplify-design. Use when --deep flag is set, for epics, complex features (30+ tasks), or when auto_deep_mode preference is enabled. Invokes assumption questioning, codebase soul analysis, and ruthless simplification. (project)
