Guide the user through parallel development workflows using Ghostty terminal panels, git worktrees, and Lazygit. This is both a teaching experience and a practical reference.

---

## Preflight

Before starting, detect the user's environment:

```bash
git rev-parse --is-inside-work-tree 2>&1 && echo "GIT_OK" || echo "NOT_GIT"
```

**If not a git repo:**
> This isn't a git repository. Navigate to a git project first, then come back to `/worktree-guide`.

Check if we're in a worktree or main repo:
```bash
git worktree list
pwd
```

Note the context for later guidance.

## Worktree Parallel Development Guide

Welcome! I'll guide you through setting up and using parallel worktrees for multi-task development.

**Your workflow:**
1. Create worktrees → `/worktree-init`
2. Open Ghostty panels → `Cmd+D` / `Cmd+Shift+D`
3. Run Claude in each panel → `cd <worktree> && claude`
4. Deliver when done → `/worktree-deliver`
5. Clean up → `/worktree-cleanup`

What would you like to do?
```

Use AskUserQuestion:
- "Learn the full workflow" — Start from Phase 2
- "Just show keybindings" — Jump to Quick Reference
- "Create worktrees now" — Suggest `/worktree-init`
- "Something else" — Ask what they need

**If already in a worktree:**
```
## Worktree Status

You're already inside a worktree! Let me check your status.
```

Then run the equivalent of `/worktree-check` and provide contextual guidance.

**Monitoring workflow:**
1. Open lazygit in the main repo (or a dedicated Ghostty panel)
2. Press `w` to see all worktrees
3. Use Enter to dive into any worktree's changes
4. Press `q` to go back to the worktree list
```

## Phase 4: Complete Workflow (Guided)

**EXPLAIN:**
```
## Full Parallel Development Workflow

Let me walk you through the complete cycle. We'll go step by step.
```

### Step 4.1: Create Worktrees

**EXPLAIN:**
```
### Step 1: Create Worktrees

First, define the tasks you want to work on in parallel. The `/worktree-init` command creates a worktree for each task.
```

**DO:** Show example command:
```
Example usage:

/worktree-init add user authentication | fix login bug | improve dashboard performance

This creates:
├── ../worktrees/<repo>/claude-add-user-authentication/
├── ../worktrees/<repo>/claude-fix-login-bug/
└── ../worktrees/<repo>/claude-improve-dashboard-performance/
```

### Step 4.2: Open Ghostty Panels

**EXPLAIN:**
```
### Step 2: Open Ghostty Panels

Now split your terminal into panels—one for each task, plus optionally one for Lazygit monitoring.
```

**DO:**
```
1. Press Cmd+D to split right (first worktree)
2. Press Cmd+D again (second worktree)
3. Optionally press Cmd+Shift+D on any panel for Lazygit below

Resulting layout:
┌──────────┬──────────┬──────────┐
│ Task 1   │ Task 2   │ Task 3   │
│ claude   │ claude   │ claude   │
├──────────┴──────────┴──────────┤
│           lazygit              │
└────────────────────────────────┘
```

### Step 4.3: Work in Each Panel

**EXPLAIN:**
```
### Step 3: Work Independently

In each panel:
1. cd to the worktree path (from the commands output)
2. Run `claude` to start a Claude session
3. Use `/worktree-check` anytime to verify which task you're working on
4. Work normally—Claude doesn't know about other panels
```

### Step 4.4: Deliver Completed Work

**EXPLAIN:**
```
### Step 4: Deliver When Done

When you finish a task in any panel, use `/worktree-deliver` to:
1. Review your changes
2. Create a commit
3. Push to remote
4. Create a pull request
```

### Step 4.5: Clean Up

**EXPLAIN:**
```
### Step 5: Clean Up After Merging

After your PRs are merged on GitHub:
1. Go back to the main repo (not a worktree)
2. Run `/worktree-cleanup --all`
3. It removes merged worktrees and branches
```

---

## Phase 5: Troubleshooting

**SHOW:**
```
## Troubleshooting

### "I'm not sure which worktree I'm in"

Run `/worktree-check` — it shows your branch, task, and status.

Alternatively:
$ git branch --show-current    # Shows claude/<name>
$ pwd                          # Shows the worktree path

---

### "I have uncommitted changes and want to switch tasks"

**Option 1:** Commit work-in-progress
$ git add . && git commit -m "wip: progress on feature"

**Option 2:** Stash changes (temporary)
$ git stash push -m "wip: parking changes"

Then in the other panel, continue working. Come back later with:
$ git stash pop

---

### "I accidentally started working in the wrong worktree"

1. Stash your changes: `git stash push -m "work done in wrong place"`
2. Navigate to the correct worktree
3. Apply the stash: `git stash pop`

---

### "My worktree has merge conflicts"

1. Run `git fetch origin` to get latest
2. Run `git rebase origin/main` (or merge if you prefer)
3. Resolve conflicts in your editor
4. `git add .` then `git rebase --continue`

---

### "I want to abandon a worktree"

From the main repo:
$ git worktree remove ../worktrees/repo/claude-<name> --force
$ git branch -D claude/<name>

Note: Force is needed if there are uncommitted changes.

---

### "/worktree-deliver failed on push"

Usually means the remote branch doesn't exist yet or there's a conflict.

Try:
$ git push -u origin HEAD

If there's a conflict with remote, pull first:
$ git pull --rebase origin claude/<name>

---

### "The worktree path doesn't exist anymore"

The worktree was probably deleted manually. Clean up the git state:
$ git worktree prune
```

## Guardrails

- **Never execute destructive commands** without confirmation (worktree remove, branch delete)
- **Always verify location** before suggesting worktree operations
- **If user seems lost**, offer `/worktree-check` first
- **Never force-delete** branches that aren't merged
- **Don't assume tools are installed** — check for lazygit availability if suggesting it
- **Respect user's pace** — don't rush through sections if they want to practice
- **Keep the reference card available** — offer to show it whenever relevant
