Merge

Merge - Branch Management

Patterns for merging worker branches and handling conflicts.

CRITICAL: Always kill the worker terminal BEFORE merging. See @references/terminal-cleanup.md

Standard Merge Flow

ISSUE_ID="ISSUE-ID"
TABZ_API="http://localhost:8129"
TOKEN=$(cat /tmp/tabz-auth-token)

# 1. Kill worker terminal first
AGENT_ID=$(curl -s "$TABZ_API/api/agents" | jq -r --arg id "$ISSUE_ID" \
  '.data[] | select(.name == $id) | .id')
[ -n "$AGENT_ID" ] && curl -s -X DELETE "$TABZ_API/api/agents/$AGENT_ID" \
  -H "X-Auth-Token: $TOKEN"

# 2. Ensure on main
git checkout main
git pull

# 3. Merge feature branch
git merge "feature/$ISSUE_ID" --no-edit

# 4. Remove worktree and branch
git worktree remove ".worktrees/$ISSUE_ID" --force
git branch -d "feature/$ISSUE_ID"

# 5. Sync and push
bd sync
git push

One-Command Alternative

For full cleanup with checkpoints, capture, and terminal kill:

./plugins/conductor/scripts/finalize-issue.sh "$ISSUE_ID"

Conflict Detection

# Test merge without committing
git merge --no-commit --no-ff "feature/$ISSUE_ID"
git merge --abort

If conflicts exist, git merge will fail with conflict markers.

Conflict Resolution

Don't auto-resolve. Report conflicts for manual resolution:

# Get conflict files
git diff --name-only --diff-filter=U

# Show conflict details
git diff --check

Manual Resolution Steps

1. Navigate to worktree: cd .worktrees/ISSUE-ID
2. Open conflicting files
3. Resolve conflicts (remove markers, choose correct code)
4. Stage: git add .
5. Commit: git commit
6. Re-run cleanup

Merge Strategies

Fast-Forward (Clean history)

git merge --ff-only "feature/$ISSUE_ID"

Only works if main hasn't changed.

No-FF (Always create merge commit)

git merge --no-ff "feature/$ISSUE_ID"

Creates merge commit even if fast-forward possible.

Squash (Single commit)

git merge --squash "feature/$ISSUE_ID"
git commit -m "feat: description (ISSUE-ID)"

Combines all commits into one.

Default: Use --no-edit for automatic merge commit message.

Worktree Cleanup

# Remove worktree (--force ignores uncommitted changes)
git worktree remove ".worktrees/ISSUE-ID" --force

# List remaining worktrees
git worktree list

# Prune stale worktree references
git worktree prune

Branch Cleanup

# Delete local branch (fails if not merged)
git branch -d "feature/ISSUE-ID"

# Force delete (use carefully)
git branch -D "feature/ISSUE-ID"

# Delete remote branch
git push origin --delete "feature/ISSUE-ID"

Batch Operations

# Find all merged feature branches
git branch --merged main | grep "feature/"

# Delete all merged feature branches
git branch --merged main | grep "feature/" | xargs git branch -d

# Find orphaned worktrees
git worktree list | grep -v "$(pwd)$"

Error Handling

Safety Checks

Before merging:

1. Verify issue is closed
2. Kill worker terminal via TabzChrome API (see @references/terminal-cleanup.md)
3. Verify branch exists
4. Check for conflicts first

After merging:

1. Verify merge succeeded
2. Run any CI checks
3. Sync beads
4. Push to remote
