Merging & Cleanup - Automagik Suite Documentation

Overview

After comparing attempts and choosing the best approach, it’s time to merge those changes into your main branch and clean up temporary worktrees.

The Merge Process

Merging Attempts

Via Web UI

Review Changes

Open task details → Click on completed attempt

Review Diff

Check all file changes carefully:

Files modified
Lines added/removed
Tests passing

Approve

Click “Approve & Merge” button

Confirm

Confirm merge in dialog:

Merge attempt #2 (gemini) into main?

Files changed: 8
Additions: +269
Deletions: -16

[Cancel] [Merge]

Success

Task moves to “Done” column Worktree auto-cleaned

Via CLI

# Basic merge
forge task merge 1 --attempt 2

# Merge with message
forge task merge 1 --attempt 2 \
  --message "Add JWT authentication (Gemini implementation)"

# Merge and close task
forge task merge 1 --attempt 2 --close

# Merge without cleanup (keep worktree)
forge task merge 1 --attempt 2 --no-cleanup

Merge Strategies

Fast-Forward Merge (Default)

Clean, linear history:

forge task merge 1 --attempt 2 --ff

# Git history:
# * abc123 Add authentication (gemini)
# * def456 Previous commit
# * ...

When to use: Single-developer, clean history preferred

Merge Commit

Preserves attempt branch history:

forge task merge 1 --attempt 2 --no-ff

# Git history:
# *   abc123 Merge task-1-gemini
# |\
# | * def456 Implement JWT tokens
# | * ghi789 Add login endpoint
# |/
# * jkl012 Previous commit

When to use: Multiple developers, want to preserve attempt context

Squash Merge

Combine all commits into one:

forge task merge 1 --attempt 2 --squash

# Git history:
# * abc123 Add user authentication
#   - Implemented JWT tokens
#   - Added login/signup endpoints
#   - Added tests
# * def456 Previous commit

When to use: Clean up messy attempt history, single commit per feature

Pre-Merge Checks

Forge runs automatic checks before merging:

Test Suite

forge task merge 1 --attempt 2

# Automatic checks:
Running pre-merge checks...
✓ All tests pass (24/24)
✓ Linting passed
✓ Type checking passed
✓ No merge conflicts
✓ Branch up to date with main

Ready to merge!

Custom Pre-Merge Hooks

Configure in .forge/hooks.yaml:

pre_merge:
  - run: "npm test"
    required: true
  - run: "npm run lint"
    required: true
  - run: "npm run build"
    required: true
  - run: "npm audit"
    required: false  # Warn but don't block

If any required check fails, merge is blocked:

❌ Pre-merge checks failed

  ✓ Tests passed
  ✓ Linting passed
  ❌ Build failed: TypeScript errors in src/auth/login.ts

Merge blocked. Fix errors and try again.

Handling Merge Conflicts

Detecting Conflicts

forge task merge 1 --attempt 2

# Output:
❌ Merge conflicts detected

Conflicts in:
  - src/auth/login.ts (3 conflicts)
  - package.json (1 conflict)

[Resolve Manually] [Use Ours] [Use Theirs] [Abort]

Resolving Conflicts

Manual Resolution
Interactive Resolution
Automated Strategies

# Open conflicted files
forge task conflicts 1 --attempt 2

# Edit conflicts in your editor:
<<<<<<< HEAD (main)
const PORT = 3000;
=======
const PORT = 8080;
>>>>>>> task-1-gemini

# Choose one or combine:
const PORT = process.env.PORT || 3000;

# Mark as resolved
git add src/auth/login.ts

# Continue merge
forge task merge 1 --attempt 2 --continue

Post-Merge Actions

Automatic Actions

After successful merge, Forge can:

.forge/hooks.yaml

post_merge:
  - run: "npm run build"
  - run: "git push origin main"
  - notify:
      slack: "#engineering"
      message: "Task #{{task.id}} merged by {{user.name}}"
  - create_pr:  # If feature branch
      title: "{{task.title}}"
      body: "Closes #{{task.id}}"

Manual Post-Merge Steps

Common things you might do:

# Push to remote
git push origin main

# Tag release
git tag -a v1.2.0 -m "Add authentication"
git push origin v1.2.0

# Deploy
npm run deploy

# Notify team
forge task comment 1 \
  --message "@team Authentication is live in production!"

Cleanup

Automatic Cleanup (Default)

Forge automatically cleans up after merge:

forge task merge 1 --attempt 2

# Automatic cleanup:
✓ Merged to main
✓ Removed git worktree
✓ Cleaned up temporary files
✓ Archived attempt logs
✓ Updated task status

Done! 🎉

Manual Cleanup

Sometimes you want to keep the worktree:

# Merge without cleanup
forge task merge 1 --attempt 2 --no-cleanup

# Later, clean up manually
forge worktree remove task-1-gemini

# Or clean all merged worktrees
forge worktree cleanup --merged

Cleanup Rejected Attempts

# Remove specific attempt
forge task remove-attempt 1 --attempt 1

# Remove all rejected attempts
forge task cleanup 1 --rejected-only

# Remove all attempts except winner
forge task cleanup 1 --keep-merged

Worktree Management

List Worktrees

# List all worktrees
forge worktree list

# Output:
/Users/you/project           abc123 [main]
.forge/worktrees/task-1      def456 [task-1-claude]
.forge/worktrees/task-2      ghi789 [task-2-gemini]

# Git's native command
git worktree list

Remove Worktrees

# Remove specific worktree
forge worktree remove task-1-claude

# Or use git directly
git worktree remove .forge/worktrees/task-1-claude

# Force remove (if needed)
git worktree remove --force .forge/worktrees/task-1-claude

Clean Orphaned Worktrees

Sometimes worktrees get orphaned (branch deleted but directory remains):

# Detect and remove orphaned worktrees
forge worktree cleanup

# Output:
Found 3 orphaned worktrees:
  - .forge/worktrees/task-old-1
  - .forge/worktrees/task-old-2
  - .forge/worktrees/temp-experiment

Remove all? [y/N] y

✓ Cleaned 3 orphaned worktrees
Freed 156 MB of disk space

Forge runs this automatically, but you can trigger it manually if needed

Rolling Back Merges

Made a mistake? Undo the merge:

Immediate Rollback

# If you just merged
git reset --hard HEAD~1

# Via Forge
forge task rollback 1

Revert Merge

After pushing to remote:

# Create revert commit
git revert -m 1 abc123

# Via Forge
forge task revert 1 --create-issue

This creates a new commit that undoes the merge, preserving history.

Merge Best Practices

Always Review First

Never merge without reviewing:

# Good workflow
forge task review 1 --attempt 2
forge task test 1 --attempt 2
forge task merge 1 --attempt 2

# Bad workflow
forge task merge 1 --attempt 2 --force

Keep Main Stable

Main branch should always work:

All tests must pass
No known bugs
Builds successfully
Deployed confidently

Meaningful Commit Messages

# Good
forge task merge 1 --message \
  "Add JWT authentication with refresh tokens

  - Implemented login/signup endpoints
  - Added bcrypt password hashing
  - Configured JWT with 24h expiry
  - Added comprehensive tests (95% coverage)"

# Bad
forge task merge 1 --message "auth stuff"

Clean Up Regularly

Don’t let worktrees accumulate:

# Weekly cleanup
forge worktree cleanup

# Check disk usage
du -sh .forge/worktrees

Old worktrees waste disk space

Advanced: Partial Merges

Sometimes you want only specific files from an attempt:

# Merge only specific files
forge task cherry-pick 1 --attempt 2 \
  --files "src/auth/*.ts"

# Or manually
git checkout task-1-gemini -- src/auth/login.ts
git commit -m "Cherry-pick login from attempt #2"

Integration with CI/CD

Trigger Builds on Merge

.github/workflows/forge-merge.yml

name: Forge Merge

on:
  push:
    branches: [ main ]
    # Only when Forge merges
    paths:
      - '!.forge/**'

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Deploy
        run: npm run deploy

Merge Gates

Require CI checks before merge:

.forge/config.json

{
  "mergeGates": {
    "requireCI": true,
    "requireReview": true,
    "requireTests": true,
    "minCoverage": 80
  }
}

Troubleshooting

Merge fails with 'detached HEAD'

Error: “Cannot merge: worktree is in detached HEAD state”Solution:

# Checkout proper branch in worktree
cd .forge/worktrees/task-1-attempt
git checkout task-1-claude

# Retry merge
forge task merge 1 --attempt 1

'Worktree still in use' error

Error: “Cannot remove worktree: directory is locked”Solution:

# Check for running processes
lsof | grep ".forge/worktrees/task-1"

# Kill processes if needed
pkill -f task-1

# Force remove
git worktree remove --force .forge/worktrees/task-1

Merge creates huge commit

Issue: Merge commit contains unintended filesSolution:

Check .gitignore is proper
Ensure node_modules/ not committed
Review files before merge:
```
forge task files 1 --attempt 2
```

Abort and fix:

git merge --abort
# Fix .gitignore
git add .gitignore
git commit -m "Update .gitignore"
# Retry merge

Can't push after merge

Error: “Updates were rejected because the remote contains work that you do not have locally”Solution:

# Pull and rebase
git pull --rebase origin main

# Resolve conflicts if any
git add .
git rebase --continue

# Push
git push origin main

Cleanup Schedule

Recommended cleanup schedule:

Frequency	Action	Command
Daily	Remove merged worktrees	`forge worktree cleanup --merged`
Weekly	Remove old attempt logs	`find .forge/logs -mtime +7 -delete`
Monthly	Archive old tasks	`forge task archive --older-than 30d`
Quarterly	Compact database	`sqlite3 .forge/forge.db "VACUUM;"`
