| Merging from multiple worktrees in current branch | PASS | Strategy E (lines 62-67), Multi-Worktree Workflow (lines 195-211) |
| Picking which changes from each to merge | PASS | Strategies B, D, E with selective staging |
| Selective File Checkout | PASS | Strategy A: `git checkout <branch> -- <path>` |
| Interactive Patch Selection | PASS | Strategy B: `git checkout -p`, Patch Mode Guide (lines 149-172) |
| Cherry-Pick with No-Commit + Reset | PASS | Strategy C with full workflow (lines 43-51, 174-193) |

## Evaluation Criteria Scores

### 1. Correctness (35%) - Score: 33/35

All required merge strategies are implemented:

- **Strategy A: Selective File Checkout** - For complete files from another branch
- **Strategy B: Interactive Patch Selection** - For selecting specific hunks/lines
- **Strategy C: Cherry-Pick with Selective Staging** - For commits with partial changes
- **Strategy D: Manual Merge with Conflicts** - For full branch merge with control
- **Strategy E: Multi-Worktree Selective Merge** - For combining from multiple sources

The cleanup prompt is properly positioned in Step 7 to execute after successful merge.

### 2. Integration (25%) - Score: 24/25

Pattern consistency with Steps 1-2:

| Pattern Element | Matches create-worktree | Matches compare-worktrees |
|-----------------|-------------------------|---------------------------|
| Frontmatter format | Yes | Yes |
| `model: haiku` | Yes | Yes |
| `allowed-tools` pattern | Yes | Yes |
| Title format | Yes | Yes |
| Instructions section | Yes | Yes |
| Tables for reference | Yes | Yes |
| Examples section | Yes | Yes |
| Important Notes | Yes | Yes |
| Troubleshooting | Yes | Yes |
| Integration references | Yes | Yes |

### 3. Completeness (25%) - Score: 24/25

All required elements present:

- 5 merge strategies (A-E)
- Strategy reference table
- Interactive mode (`--interactive`)
- Cleanup prompt in Step 7
- Cleanup After Merge section with commands
- Troubleshooting section
- Integration with compare-worktrees

Minor gap: Could explicitly mention `git restore` as Strategy F (Git 2.23+ alternative mentioned in SKILL.md).

### 4. Quality (15%) - Score: 14/15

User-friendliness assessment:

- Clear section headers with logical flow
- Step-by-step numbered instructions
- Strategy selection guide with "Best for" descriptions
- Comprehensive examples covering all use cases
- Interactive patch mode guide with key explanations
- Cherry-pick selective workflow with full command sequence
- Multi-worktree merge workflow with practical example
- Common workflows section
- Troubleshooting with cause/solution format

## Verification Questions & Answers

**Q1: Does the command properly handle the `--interactive` flag for guided mode?**

A1: Yes. Line 19 shows `--interactive` or no arguments triggers "Guided interactive mode". The example on lines 123-138 demonstrates the full guided mode flow. Steps 3d-e explain worktree selection in interactive mode.

**Q2: Does the cleanup prompt appear AFTER successful merge as required?**

A2: Yes. Step 7 (lines 80-84) explicitly states "After successful merge, ask:" followed by cleanup options. The Cleanup After Merge section (lines 257-275) reinforces with "The command will prompt you about cleanup after each successful merge."

**Q3: Are all four specified merge techniques from the spec implemented?**

A3: Yes, all four are implemented:
- Selective File Checkout = Strategy A (lines 35-37)
- Interactive Patch Selection = Strategy B (lines 39-42)
- Cherry-Pick with No-Commit + Reset = Strategy C (lines 43-51)
- Manual Merge with Conflicts = Strategy D (lines 53-60)

## Final Score Calculation

| Criterion | Weight | Score | Weighted |
|-----------|--------|-------|----------|
| Correctness | 35% | 33/35 | 0.94 |
| Integration | 25% | 24/25 | 0.96 |
| Completeness | 25% | 24/25 | 0.96 |
| Quality | 15% | 14/15 | 0.93 |
| **Total** | 100% | | **4.5/5.0** |

## Issues

None identified. All requirements have been met.

---

## Suggested Improvements

1. **Add `git restore` as Strategy F** - The SKILL.md file mentions `git restore` (Git 2.23+) as an alternative method. This could be added as an optional strategy for users on newer Git versions.

2. **Enhanced interactive mode guidance** - While `--interactive` is documented, the instructions section could include more explicit step-by-step prompts for the guided mode flow.

## Conclusion

The merge-worktree command implementation is complete, well-structured, and follows all established patterns from the previous steps. It successfully implements all required merge strategies (Selective File Checkout, Interactive Patch Selection, Cherry-Pick with No-Commit + Reset, Manual Merge with Conflicts) plus an additional Multi-Worktree Selective Merge strategy. The cleanup prompt is properly positioned to execute after successful merge operations.

**VERDICT: PASS**
