## [5.2.2] - 2025-11-03

### ✨ Added

**`/memory:skill-memory` Intelligent Skip Logic**:
- ✨ **Smart Documentation Generation** - Automatically detects existing documentation and skips regeneration
  - If docs exist AND no `--regenerate` flag: Skip Phase 2 (planning) and Phase 3 (generation)
  - Jump directly to Phase 4 (SKILL.md index generation) for fast SKILL updates
  - If docs exist AND `--regenerate` flag: Delete existing docs and regenerate from scratch
  - If no docs exist: Run full 4-phase workflow
- ✨ **Phase 4 Always Executes** - SKILL.md index is never skipped, always generated or updated
  - Ensures SKILL index stays synchronized with documentation structure
  - Lightweight operation suitable for frequent execution
- ✨ **Skip Path Documentation** - Added comprehensive TodoWrite patterns for both execution paths
  - Full Path: All 4 phases (no existing docs or --regenerate specified)
  - Skip Path: Phase 1 → Phase 4 (existing docs found, no --regenerate)
  - Auto-Continue flow diagrams for both paths

### 🔄 Changed

**Parameter Naming Correction**:
- 🔄 **`--regenerate` Flag** - Reverted `--update` back to `--regenerate` in `/memory:skill-memory`
  - More accurate naming: "regenerate" means delete and recreate (destructive)
  - "update" was misleading as it implied incremental update (not implemented)
  - Fixed naming consistency across all documentation and examples

**Phase 1 Enhancement**:
- 🔄 **Step 4: Determine Execution Path** - Added decision logic to Phase 1
  - Checks existing documentation count
  - Evaluates --regenerate flag presence
  - Sets SKIP_DOCS_GENERATION flag based on conditions
  - Displays appropriate skip or regeneration messages

### 🎯 Benefits

**Performance Optimization**:
- ⚡ **Faster SKILL Updates** - Skip documentation generation when docs already exist (~5-10x faster)
- ⚡ **Always Fresh Index** - SKILL.md regenerated every time to reflect current documentation structure
- ⚡ **Conditional Regeneration** - Explicit --regenerate flag for full documentation refresh

**Workflow Efficiency**:
- 🔗 Smart detection reduces unnecessary documentation regeneration
- 🔗 Clear separation between SKILL index updates and documentation generation
- 🔗 Explicit control via --regenerate flag when full refresh needed

### 📦 Modified Files

- `.claude/commands/memory/skill-memory.md` - Added skip logic, reverted parameter naming, comprehensive execution path documentation
