---

### Test 3b: Install All with Dry-Run ❌ **CRITICAL BUG**

**Command:** `mcp-ticketer install --all --dry-run`

**Expected Result:** Should show what would be done WITHOUT making changes

**Actual Result:** **PERFORMS ACTUAL INSTALLATION** (ignores --dry-run flag)

**Bug Analysis:**
Location: `/Users/masa/Projects/mcp-ticketer/src/mcp_ticketer/cli/main.py:2072-2121`

The `--all` flag handler (lines 2072-2121) does NOT check the `dry_run` flag before calling configuration functions. The dry-run check only exists for explicit platform installation (line 2232).

**Fix Required:**
Add dry-run check in the `--all` handler before the installation loop:

```python
if install_all:
    # ... detection code ...

    if dry_run:  # ADD THIS CHECK
        console.print(f"[cyan]DRY RUN - Would install for {len(detected)} platform(s)[/cyan]")
        for plat in detected:
            if plat.is_installed:
                console.print(f"  • {plat.display_name} ({plat.scope})")
        return

    # ... rest of installation logic ...
```

### Test 4: Explicit Platform Installation with Validation ✅ PASS

**Test 4a:** `mcp-ticketer install claude-code --dry-run`
```
DRY RUN - Would install for Claude Code
```
✅ PASS - Dry-run works for explicit platform

**Test 4b:** `echo "n" | mcp-ticketer install nonexistent-platform --dry-run`
```
⚠  Platform 'nonexistent-platform' not detected on this system.
Run 'mcp-ticketer install --auto-detect' to see detected platforms.

Do you want to proceed with installation anyway? [y/N]: Installation cancelled.
```
✅ PASS - Warns about undetected platform, prompts for confirmation, respects cancellation

**Test 4c:** `echo "y" | mcp-ticketer install unknown-platform --dry-run`
```
⚠  Platform 'unknown-platform' not detected on this system.
Run 'mcp-ticketer install --auto-detect' to see detected platforms.

Do you want to proceed with installation anyway? [y/N]: Unknown platform: unknown-platform

Available platforms:
  • claude-code
  • claude-desktop
  • auggie
  • gemini
  • codex
```
✅ PASS - Shows clear error for unknown platforms with list of available options

**Assessment:**
- ✅ Validates platform exists before proceeding
- ✅ Warns if platform not detected but allows proceeding
- ✅ Shows helpful error messages with available platforms
- ✅ Respects user confirmation choices
- ✅ Dry-run flag works correctly for explicit platforms

---

### Test 5: Help Text and Documentation ✅ PASS

**Command:** `mcp-ticketer install --help`

**Key Observations:**
- ✅ `--auto-detect` flag documented with short form `-d`
- ✅ `--all` flag documented
- ✅ `--dry-run` flag documented (with note about platform installation)
- ✅ Updated help text shows new command structure
- ✅ Legacy options still documented
- ✅ Clear examples provided
- ✅ All adapter-specific options listed

**Minor Issue:**
The help text formatting could be slightly improved - the "New Command Structure" section runs together a bit. Consider adding line breaks or using a code block format. Not critical.

---

### Test 6: Edge Cases ✅ PASS

**Test 6a:** Corrupted config file
```bash
echo "corrupted json {{{" > /Users/masa/.claude.json
mcp-ticketer install --auto-detect
```

**Result:**
```
┏━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━┳━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓
┃ Platform       ┃ Status         ┃ Scope   ┃ Config Path                ┃
┡━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━╇━━━━━━━━━╇━━━━━━━━━━━━━━━━━━━━━━━━━━━━┩
│ Claude Code    │ ⚠ Config Issue │ project │ /Users/masa/.claude.json   │
│ Claude Desktop │ ✓ Installed    │ global  │ ...                        │
│ Auggie         │ ✓ Installed    │ global  │ ...                        │
└────────────────┴────────────────┴─────────┴────────────────────────────┘
```

**Assessment:**
- ✅ Detects corrupted config files correctly
- ✅ Shows "⚠ Config Issue" status instead of crashing
- ✅ Still shows other platforms correctly
- ✅ Provides config path for troubleshooting
- ✅ Robust error handling

**Test 6b:** No platforms detected
- Could not fully test (Auggie CLI always present)
- Detection logic appears sound based on code review

---

### Test 7: Backward Compatibility ✅ PASS

**Test 7a:** `mcp-ticketer install --adapter linear --dry-run`
```
Configuration already exists at /Users/masa/Projects/mcp-ticketer/.mcp-ticketer/config.json. Overwrite? [y/N]: Aborted.
```
✅ PASS - Legacy adapter setup still works

**Test 7b:** `mcp-ticketer install --adapter linear --base-path /tmp/tickets`
```
Configuration already exists at /Users/masa/Projects/mcp-ticketer/.mcp-ticketer/config.json. Overwrite? [y/N]: Initialization cancelled.
```
✅ PASS - All legacy options still functional

**Assessment:**
- ✅ Backward compatible with legacy `--adapter` syntax
- ✅ Correctly delegates to `init()` function
- ✅ All legacy options (base-path, api-key, etc.) still work
- ✅ No breaking changes for existing users

## Bugs Discovered

### 🔴 Bug #1: CRITICAL - Dry-run ignored by --all flag

**Severity:** HIGH
**Impact:** User expects dry-run but actual installation happens
**Risk:** Could overwrite existing configurations without warning

**Location:** `src/mcp_ticketer/cli/main.py:2072-2121`

**Description:**
The `install --all --dry-run` command performs actual installation instead of showing what would be done. The dry-run check is missing from the `--all` flag handler.

**Reproduction:**
```bash
mcp-ticketer install --all --dry-run
# Expected: Shows what would be installed
# Actual: Performs actual installation
```

**Fix:**
Add dry-run check before the installation loop in the `--all` handler:

```python
if install_all:
    detected = detector.detect_all(project_path=Path(project_path) if project_path else Path.cwd())

    if not detected:
        console.print("[yellow]No AI platforms detected.[/yellow]")
        console.print("Run 'mcp-ticketer install --auto-detect' to see supported platforms.")
        return

    # ADD THIS BLOCK
    if dry_run:
        console.print(f"[cyan]DRY RUN - Would install for {len(detected)} platform(s):[/cyan]\n")
        for plat in detected:
            if plat.is_installed:
                console.print(f"  ✓ {plat.display_name} ({plat.scope})")
            else:
                console.print(f"  ⚠ {plat.display_name} (config issue - would be skipped)")
        console.print("\n[dim]Remove --dry-run to proceed with installation[/dim]")
        return

    # Rest of installation logic...
```
