Phase 3 Plan 2: WorktreeManager Adapter Implementation Summary

SimpleGitWorktreeManager adapter with simple-git and 23 comprehensive tests covering create, remove, list, get, diff, and merge operations

Performance

• Duration: 5 min
• Started: 2026-01-30T18:26:23Z
• Completed: 2026-01-30T18:30:55Z
• Tasks: 3
• Files modified: 4

Accomplishments

• Implemented SimpleGitWorktreeManager class with all 6 WorktreeManager port methods
• Added simple-git dependency for git CLI operations
• Created 23 comprehensive tests covering CRUD, diff, and merge operations
• All 4 git events properly emitted (created, removed, merged, conflict)
• Conflict detection and abort/cleanup working correctly

Task Commits

Each task was committed atomically:

1. Task 1: Install simple-git and create WorktreeManager adapter with CRUD - 0cf2849 (feat)
2. Task 2: Implement diff and merge operations - (included in Task 1 - same file)
3. Task 3: Write tests for WorktreeManager - c32bc55 (test)

Files Created/Modified

Created:

• src/git/manager.ts - SimpleGitWorktreeManager adapter implementing WorktreeManager port
• src/git/manager.test.ts - 23 tests with temp repo setup for each test

Modified:

• src/git/index.ts - Added export for SimpleGitWorktreeManager adapter
• package.json - Added simple-git dependency

Decisions Made

• Task 1 expansion: Implemented all 6 methods (create, remove, list, get, diff, merge) in Task 1 since they're all in the same file. Task 2 verification passed as the code was already complete.
• Worktree storage: Worktrees created in .cw-worktrees directory within the repository
• Event injection: EventBus is optional constructor parameter - same DI pattern used by other adapters
• Test strategy: Each test gets a fresh temp git repo with initial commit - isolation prevents test interference

Deviations from Plan

Auto-merged Tasks

1. [Tasks 1+2 merged] All WorktreeManager methods implemented in single task

• Reason: Tasks 1 and 2 both modify src/git/manager.ts - splitting would create artificial commit boundary
• Impact: Two commits instead of three, functionally equivalent result
• Files: src/git/manager.ts contains all CRUD + diff + merge methods

---

Total deviations: 1 (task merge for efficiency) Impact on plan: No functional difference - all methods implemented and tested

Issues Encountered

None - implementation followed plan and all tests pass.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• WorktreeManager adapter fully implemented and tested
• All 4 GIT requirements satisfied:
  • GIT-01: create() provides isolated worktree per agent
  • GIT-02: diff() previews agent's changes
  • GIT-03: merge() integrates changes to target branch
  • GIT-04: remove() cleans up worktree
• Ready for Phase 4: Agent Lifecycle which will use WorktreeManager for agent isolation
• No blockers
