# Verification Report: Create Worktree Command (Step 1/3)

**Date:** 2026-01-30
**Evaluator:** Claude Opus 4.5
**Implementation:** `/home/leovs09/work/neolab/context-engineering-kit/plugins/git/commands/create-worktree.md`

---
VERDICT: PASS
SCORE: 4.4/5.0
ISSUES:
  - None
IMPROVEMENTS:
  - Consider adding `Bash(mkdir:*)` to allowed-tools for edge cases where worktree directory parent needs creation
  - Could add `Bash(cd:*)` to allowed-tools to allow explicit directory navigation after creation
  - The `--list` flag handling could be documented in frontmatter's `argument-hint`

## Evaluation Summary

| Criterion | Weight | Score | Weighted |
|-----------|--------|-------|----------|
| Correctness | 35% | 4.5/5 | 1.58 |
| Integration | 25% | 4.5/5 | 1.13 |
| Completeness | 25% | 4.2/5 | 1.05 |
| Quality | 15% | 4.5/5 | 0.68 |
| **TOTAL** | 100% | | **4.44/5.0** |

## Detailed Evaluation

### 1. Correctness (35%) - Score: 4.5/5

**Requirement Verification:**

| Requirement | Status | Evidence |
|-------------|--------|----------|
| Creates worktree(s) based on user input | PASS | Lines 20-36: Detailed branch resolution logic for local, remote, and new branches |
| Sets up worktree with dependency installation | PASS | Lines 38-55: Comprehensive dependency detection and package manager selection |
| Detects whether setup is needed | PASS | Lines 38-44: Detects package.json, requirements.txt, Cargo.toml, go.mod, etc. |
| Allows creating 1 or many worktrees | PASS | Lines 21-24: Supports single, multiple (comma/space separated), --list, and interactive modes |
| Follows patterns from existing git plugin commands | PASS | Matches commit.md structure with frontmatter, instructions, examples, and notes |

**Strengths:**
- Comprehensive branch resolution logic (local, remote, new branch scenarios)
- Smart package manager detection (bun, pnpm, yarn, npm based on lockfiles)
- Proper path naming convention with prefix stripping (feature/, fix/, etc.)
- Confirmation prompt before running install commands (respects user control)

**Minor Gaps:**
- No explicit handling for bare repositories (edge case)

### 2. Integration (25%) - Score: 4.5/5

**Pattern Comparison with commit.md:**

| Pattern Element | commit.md | create-worktree.md | Match |
|-----------------|-----------|-------------------|-------|
| Frontmatter with description | YES | YES | PASS |
| Frontmatter with argument-hint | YES | YES | PASS |
| Frontmatter with model: haiku | YES | YES | PASS |
| Frontmatter with allowed-tools | YES | YES | PASS |
| CRITICAL instruction prefix | YES | YES | PASS |
| Numbered step instructions | YES | YES | PASS |
| Examples section | YES | YES | PASS |
| Important Notes section | YES | YES | PASS |
| Troubleshooting section | NO | YES | ENHANCED |

**Tool Restrictions:**
- `allowed-tools` properly restricts to necessary git and package manager commands
- Includes: `git worktree:*`, `git branch:*`, `git fetch:*`, `git status:*`, `ls:*`, `pwd:*`
- Includes all major package managers: npm, yarn, pnpm, bun, pip, poetry, cargo, go

**Integration with worktrees skill:**
- Uses same path convention (`../<project>-<branch>`) as documented in SKILL.md
- Follows same branch naming patterns
- Complements the skill with automation

### 3. Completeness (25%) - Score: 4.2/5

**Required Elements Checklist:**

| Element | Present | Notes |
|---------|---------|-------|
| YAML frontmatter | YES | Lines 1-6 |
| description field | YES | Clear and descriptive |
| argument-hint field | YES | "Branch name(s) or --list to show existing worktrees" |
| model specification | YES | haiku |
| allowed-tools | YES | Comprehensive list |
| Clear instructions | YES | 5 numbered steps with sub-steps |
| Examples | YES | Multiple scenarios (single, new, multiple, list, interactive) |
| Path conventions | YES | Well-documented sibling directory pattern |
| Error handling | YES | Troubleshooting section with common issues |
| Cleanup guidance | YES | Lines 179-190 |

**Missing/Could Improve:**
- No explicit bash command execution syntax (`!` prefix for context gathering)
- Could mention the skill reference (`@plugins/git/skills/worktrees/SKILL.md`)

### 4. Quality (15%) - Score: 4.5/5

**Code Quality Indicators:**

| Aspect | Assessment |
|--------|------------|
| **Clarity** | Excellent - Instructions are step-by-step with clear decision points |
| **Organization** | Well-structured with logical sections (Instructions, Path Convention, Examples, Workflows, Notes, Cleanup, Troubleshooting) |
| **User Experience** | Good - Interactive prompts, confirmation before install, clear feedback |
| **Edge Cases** | Addressed - Branch lock, dirty working directory, existing paths |
| **Documentation** | Comprehensive examples covering common workflows |

**Highlights:**
- Clear naming rules for worktree paths (Lines 75-78)
- Multiple workflow patterns (Quick Feature, Hotfix While Feature In Progress, PR Review, Multiple Related Features)
- Dependency installation is opt-in with user confirmation
- Clear troubleshooting section with solutions

## Verification Questions

### Q1: Does the command handle the case where a user wants to create a worktree for a branch that's already checked out elsewhere?

**Answer:** YES - The Important Notes section (Line 166) explicitly addresses this: "Branch lock: Each branch can only be checked out in one worktree at a time. If a branch is already checked out, the command will inform you which worktree has it." This is also covered in the Troubleshooting section (Lines 194-196).

### Q2: Does the command follow the haiku model pattern established in commit.md?

**Answer:** YES - Line 4 specifies `model: haiku`, matching commit.md's pattern. Both commands use the haiku model for efficient execution of straightforward tasks.

### Q3: Is the dependency installation safe and user-controlled?

**Answer:** YES - Lines 52-55 explicitly require user confirmation: "Ask user if they want to run dependency installation... If yes: cd to worktree and run the install command. If no: Skip installation." This prevents unexpected side effects.

## Conclusion

The `create-worktree.md` command is a well-implemented addition to the git plugin that meets all specified requirements. It:

1. **Correctly implements** all required functionality (worktree creation, dependency setup, multiple worktrees)
2. **Properly integrates** with existing git plugin patterns (follows commit.md structure closely)
3. **Is complete** with all required frontmatter, instructions, examples, and error handling
4. **Maintains high quality** with clear organization, user-friendly prompts, and comprehensive documentation

The command is ready for use and follows established conventions. Minor improvements could enhance edge case handling, but these are not blockers.

**VERDICT: PASS** (Score: 4.4/5.0)
