✨ Added

Ultrathink Deep Planning Mode

Add Steve Jobs-inspired craftsman planning methodology with --deep flag support across all workflow commands.

• ultrathink skill: New skill for craftsman-level architecture

  • 5 Pillars: Think Different, Obsess Over Details, Plan Like Da Vinci, Simplify Ruthlessly, Iterate
  • Assumption Inventory - challenge implicit assumptions
  • Codebase Soul Analysis - understand project philosophy
  • Simplification Review - reject premature abstractions
  • Generates craftsman-decision.md artifact

• Planning depth preferences: New preference planning.auto_deep_mode with triggers

  • Epic features (>5 features)
  • High complexity (>30 tasks estimated)
  • Architecture changes

• Command support: --deep flag added to /feature, /epic, /quick, /plan

  • Forces ultrathink/craftsman mode for important decisions
  • --quick flag for standard mode when speed needed

Init/Update Command Flexibility

• npx spec-flow init and npx spec-flow update now interchangeable
  • Both commands detect existing installation state
  • Automatically run correct operation (install or update)

🐛 Fixed

Worktree Path Bugs

Fixed critical path issues where Task() agents worked in wrong directory when worktrees enabled.

• worker.md: Strengthened cd validation with error handling

  • Added path reconstruction after cd (WORKING_DIR pattern)
  • Clear instructions to forget orchestrator paths after cd

• feature.md: Pass worktree-relative paths to Task()

  • Feature slug explicitly passed for path reconstruction
  • Conditional instructions for worktree vs normal mode

• implement-epic.md: Fixed sprint worktree paths

  • Epic slug included in context
  • LOCAL_SPRINT_DIR pattern for path reconstruction

• worktree-context.sh: Added path conversion helpers

  • extract_worktree_relative_path() - fixes duplication bug
  • extract_slug_from_path() - extract slug from any path format
