Phase 06 Tier 1: Complete Backend Implementation - Recovery Tracking & Swap System

COMPLETED TASKS:
✅ 06-01: Workout Swap System
   - Added swapped_from_id to workout_logs
   - Created workout_swaps table for history
   - POST /api/workouts/:id/swap endpoint
   - GET /api/workouts/available endpoint
   - Reversible swaps with audit trail

✅ 06-02: Muscle Group Recovery Tracking
   - Created muscle_group_recovery table
   - Implemented calculateRecoveryScore() function
   - GET /api/recovery/muscle-groups endpoint
   - GET /api/recovery/most-recovered endpoint
   - Auto-tracking on workout log completion

✅ 06-03: Smart Workout Recommendations
   - GET /api/recommendations/smart-workout endpoint
   - 7-day workout analysis algorithm
   - Recovery-based filtering (>30% threshold)
   - Top 3 recommendations with context
   - Context-aware reasoning messages

DATABASE CHANGES:
- Added 4 new tables: muscle_group_recovery, workout_swaps, custom_workouts, custom_workout_exercises
- Extended workout_logs with: swapped_from_id, source_type, custom_workout_id, custom_workout_exercise_id
- Created 7 new indexes for performance

IMPLEMENTATION:
- Recovery service with 4 core functions
- 2 new route handlers (recovery, smartRecommendations)
- Updated workouts router with swap endpoints
- Integrated recovery tracking into POST /api/logs
- Full error handling and logging

TESTING:
- Test file created: /backend/test/phase-06-tests.js
- Ready for E2E and staging validation

STATUS: Ready for frontend integration and production review
Branch: feature/06-phase-06

+# Claude Code Hooks for claude-flow
+
+## Purpose
+Automatically coordinate, format, and learn from Claude Code operations using hooks.
+
+## Available Hooks
+
+### Pre-Operation Hooks
+- **pre-edit**: Validate and assign agents before file modifications
+- **pre-bash**: Check command safety and resource requirements
+- **pre-task**: Auto-spawn agents for complex tasks
+
+### Post-Operation Hooks
+- **post-edit**: Auto-format code and train neural patterns
+- **post-bash**: Log execution and update metrics
+- **post-search**: Cache results and improve search patterns
+
+### MCP Integration Hooks
+- **mcp-initialized**: Persist swarm configuration
+- **agent-spawned**: Update agent roster
+- **task-orchestrated**: Monitor task progress
+- **neural-trained**: Save pattern improvements
+
+### Session Hooks
+- **notify**: Custom notifications with swarm status
+- **session-end**: Generate summary and save state
+- **session-restore**: Load previous session state
+
+## Configuration
+Hooks are configured in `.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      {
+        "matcher": "^(Write|Edit|MultiEdit)$",
+        "hooks": [{
+          "type": "command",
+          "command": "npx claude-flow hook pre-edit --file '${tool.params.file_path}'"
+        }]
+      }
+    ]
+  }
+}
+```
+
+## Benefits
+- 🤖 Automatic agent assignment based on file type
+- 🎨 Consistent code formatting
+- 🧠 Continuous neural pattern improvement
+- 💾 Cross-session memory persistence
+- 📊 Performance metrics tracking
